Therefore any applicant must provide assessment of the effects of their proposed activity in support of their application. NHBS Ltd is registered in England and Wales: 1875194. Further information on these target seaweed and seagrass species is included in Appendix C (Table C1 ), including their general distribution on the shore, growth cycles, and. Common eelgrass ( Zostera marina) is the only species that occurs below low water mark, forming dense underwater lawns. Current level (2019) is less than 100 wet tonnes, Source: Seaweed harvesting activity table from the work of the Seaweed review steering group meeting 26 September 2019. An important ingredient in miso soup is something called kombu. ID notes: Forms fronds of variable shape which are thin and membranous. The effects of wave action occur in both the littoral and sublittoral zones of rocky shores: in general, species can be recognised as characteristic of shelter or characteristic of wave exposure [8] . generally only mature plants are harvested). Tong Garden, Dae Chun Gim) seaweed in instant noodles (eg. It is high in iodine, prebiotic fibre, antioxidants and plant protein. Turns green with exposure to bright sunlight. In this case, the ground-up seaweed was used to remove intestinal worms presumably employing the drastic method of scouring them out. Visit 'Set cookie preferences' to control specific cookies. These cover methods used in Scotland and in other countries. Collection or foraging of seaweed in small quantities for personal use is considered to be akin to "blackberrying" and does not require a lease. Positions higher up the shore in the intertidal or littoral zone are more stressful because the organisms, which are marine, have to withstand increased periods out of seawater, exposed to the drying effect of air, and the salinity shock of fresh rainwater. Further information on the specific EUNIS habitats that represent each of the broad seaweed and seagrass groups in the distribution maps and the spatial data layers used is included in Appendix C (Table C2) . The seaweed is cut about 12 inches from the base and the stump that is left will then regenerate in 3 to 4 years. This vessel works close to the shore and cuts the seaweed as the stalks float above the seabed. What I cant eat fresh, I wash and dry on my daughters trampoline in the garden. Farming will hopefully open up new markets for seaweed, which will solve what Peter tells me is one of the biggest challenges the industry faces: There is a willingness to produce seaweed and there is a wonderful product but there are gaps of clear routes to market. Peter goes on to explain why farming might help: Farming is all about producing fast-growing seaweed for a wider variety of applications which includes food but also a more diverse range including bioplastics and speciality ingredients. He adds, By growing volume through farming there are a lot of things you can do at a lower price than wild harvesting., The seaweed industry in the Highlands can be a great support for local communities. Crown Estate Scotland leasing costs: The current approach to leasing, which has been Edible; eaten as laver bread. Intertidal. The seaweed is loaded onto small boats and transferred to a sheltered area for loading onto a lorry, Recovery of growing seaweed varies according to harvesting method, frequency of cutting and time of year. www.researchgate.net/publication/269996303_Integrated_multi-trophic_aquaculture_IMTA_in_marine_temperate_waters, https://pureadmin.uhi.ac.uk/ws/portalfiles/portal/3263673/Burrows2018_1.pdf, www.gov.scot/publications/wild-seaweed-harvesting-strategic-environmental-assessment-environmental-report/, https://www.zerowastescotland.org.uk/content/integrated-multi-trophic-aquaculture, Lack of regional evidence / robust assessment criteria, but no or few concerns for some local areas, Lack of regional evidence / robust assessment criteria, but some concerns for some local areas, Lack of regional evidence / robust assessment criteria, but many concerns for some local areas. The major abiotic factors influencing seaweed and seagrass growth are light, temperature, salinity, water motion, wave exposure, nutrient availability and exposure to air (desiccation) (Lobban & Harrison, 1994; Smale et al., 2016). SC051354, Now closed: Were Hiring! L. digitata beds in Scotland are narrow and therefore mechanical harvesting is unlikely to be viable. Approximately 501 species of seaweed occur in Ireland: 272 reds, 147 browns and 80 greens. In Caithness, Ascophyllum sp is cut by hand. Seaweeds in Scotland's coastal waters fall into the following five broad categories: 3.1.2. Air bladders help seaweeds float so they can reach the sunlight and photosynthesize at the ocean surface. 3.11.3. 3.10.2. Found on rocks on lower shore. Outer Hebrides; Orkney; Caithness (Ham to Scarfskerry). In the north region, there are widespread records of maerl beds in tide-swept areas, especially in Orkney and Shetland and Loch Eriboll on the north coast of the Scottish mainland. It is therefore crucial that when we use our seas as a means of food production that we do so sustainably with as little impact as possible. Further detail and regular reporting of progress is available on the seaweed review web pages. 3.9.1. (for Clean and safe, Healthy and biologically diverse assessments), (for Clean and safe, Healthy and biologically diverse and Productive assessments), The Scottish Marine Regions (SMRs; S1 S11) and the Scottish Offshore Marine Regions (OMRs, O1 O10). * marine licences have been issued to remove kelp from around power station water intakes. We dont harvest where there are rivers running onto harvest sites. Below the low water mark, increasing depth results in a very rapid decrease in light intensity so that sublittoral (subtidal) species are restricted to a depth range near the surface, known as the photic zone, where light is sufficient for growth. Edible; used as a curry-like spice. Review of Scottish seaweed harvesting rules - BBC News This brown seaweed has paired air bladders (which look like bubbles). Guide to Wild Food Foraging in Scotland | VisitScotland An example is the replacement of Laminaria communities in Nova Scotia by sea urchins after excessive kelp removal by harvesting (see Section 6.2 ). 3.14.7. 3.16.2. The wracks are almost entirely intertidal, while the kelps dominate the subtidal, forming the kelp forest, but also extend into the lowest intertidal just above the low water mark. Intertidal. Indeed, we have been running trial seaweed farms for more than 10 years. They grow from mushroom-shaped structures of about 1in in diameter that are attached to the rocks. Distribution: Found in the mid to upper shore, generally on mussel-covered rocks. Let's take a look at a brief history of seaweed in Scotland! Despite being a foreign introduction, its never caused any problems, just the little buzz of joy in seeing something so peculiar bobbing about in the sea. Manual seaweed harvesters first encircle the cutting area with a rope or net and cut within this area. Sources: Hebridean Seaweed Company website; Just Seaweed website; McHugh (2003); Seaweed Industry Association website; The Crown Estate. Figure 2: Available spatial information on the distribution of kelps, maerl, wracks and green seaweeds, Figure 3: Available spatial information on the distribution of potential areas for kelps, and the distribution of red seaweeds, seagrasses and beach-cast seaweeds or seagrasses. Distribution: Grows in dense beds in the lower intertidal and shallow subtidal zones (at a depth of up to 20m). Other smaller beds are found along the West coast of Scotland, such as in Loch Ryan, Loch Sunart, in the Montrose Basin and in the Forth and Tay Estuaries ( JNCC, 1995; SNH, undated). Typically hand harvested at low tide with small knives or scissors. What Is Edible Seaweed? 7 Types of Seaweed and 4 Seaweed Recipes Intertidal. Purple, with flat fronds up to 20cm long. The only strandline habitat that has been recorded is in outer Tay Estuary and north coast of Orkney. It also associates all pressures that might be exerted by a defined list of activities at a particular benchmark. Where there's less wave action, it often forms dense, branched, spiny nodules up to 10cm in diameter. Well, it sometimes grows on oysters. Key deliverables are expected to cover: An OSPAR agreed list of marine pressures is used to help assessments of human activities in the marine environment. What Is Edible Seaweed? A monster of a seaweed, its our largest at up to four yards in length. (and other species mixed with it) are traditionally gathered to spread on machair land (Angus, 2009), which is also important for the biodiversity of the machair (Comhairle Nan Eilean Siar, 2013). They can outcompete other native species for food, light or space, forcing them to move or die out altogether. In Scotland, some beach-cast, Common name/s: Carragheens, Irish moss or Carrageen moss, Common name/s: Carragheens, Climhin Cait, False Irish moss, Harvested at low tide by hand with scissors or a blade above the holdfast to allow regrowth. The fund was developed by Defra and its Arm's-Length Bodies. A brown kelp up to 2m long, with frilly fronds. reading for all who are involved in land management for nature conservation, Harvesting of each species would be annual as each species grows rapidly each year. 3.14.5. There are fewer records of kelps on the east coast of Scotland, where much of the seabed is composed of sand ( SNH, undated), although some significant patches of kelps do occur, particularly along the northeast and southeast Scottish coast. It is expected that the type and scale of wild harvesting will generally continue at or around current levels, in the immediate and near future until after the seaweed review has reported. 3.12.1. It is being delivered by The National Lottery Heritage Fund in partnership with Natural England, the Environment Agency and Forestry Commission. 3.14.13. Exposed at low tide. by product type), scale (volumes, turnover, Gross Value Added (GVA) and employment) and location of seaweed based industries that may establish in Scotland. In locations with higher tidal range, it may be possible to harvest without a boat. Seaweed harvesting & cultivation activities can be associated with 24 marine pressures please read the pressure descriptions and benchmarks for further detail. Grows on rocks in mid-zone of shores. Although this species is also known as sea spaghetti, I prefer thongweed because it brings those sea nymphs to mind. Amid the flotsam and jetsam on our beaches lies a rich abundance of brown, green and red seaweeds which can be put to good culinary and cosmetic use. Methods used for cultivating particular types of seaweed can be found in Sections 2.5, 4.5 and 6.5. Operations involving the harvesting of living or beach-cast seaweed in the wild, with some exceptions, require the permission of the relevant landowner. Individual cutters handle their own cutting areas and rotate them to ensure sustainability. The renewable energy industry is interested in using seaweed in biofuel production. When we talk about farming and food production, we often think about sheep pasture or cereal fields, but of course not all of our food comes from the land. UK sea temperatures have risen 2C in the past 40 years. Most of the intertidal wrack cover is reduced. Seaweed pudding, anyone? Non-native species are those that wouldnt normally be found in the UK. Opportunists are normal members of all communities. Here are 12 for you to spot and identify. All of their harvesting areas are controlled and include designated no-take zones. 3.2. These have been used as the assessment areas for hazardous substances. Sugar kelp can be confused with Dabberlocks and Wakame. Scotland's main commercial wild seaweed harvesting is based in the Outer Hebrides and is focussed on egg or knotted wrack (Table 1). These inflate with the oxygen of photosynthesis and float in rock pools like curled intestines. Table 7: Summary of potential future harvesting activities in Scotland, Islands of the southern Firth of Lorn in Argyll (Garvellachs, Scarba, Luing, Easdale, Seil, Insh Lunga, Fladda, Eilean dubh mor, Eilean dubh beag, Mull (near Loch Buie), north shore of Jura). This is shown in Table 7 and Figure 9. For centuries, seaweeds have been harvested for food several of the dozen species pictured here are edible (and delicious). The shellfish benefit from the organic particulates and the seaweed from the soluble nutrients, including nitrogen. The current and potential distribution of each of the seaweed and seagrass groups shown in Figures 2 and 3, together with the known existing wild harvesting locations shown in Figure 8 provides an indication of the future locations that are likely to be exploited. Usually harvested in late spring and summer, from boats or by hand at low spring tides. Squeeze as you go between each roll to make sure the roll sticks together. The red seaweed usually comes pressed into thin dried sheets that are dark green or black which we eat as a snack or use to make sushi rolls. Dan Cole/The Art Agency Small, pink or purple seaweed with a feathery structure. Clicking the pressure will give you more information on the pressure and examples of how it may be associated with the activity. Revealed at low spring tides. 3.4.1. These are sub divisions of the biogeographic, or Charting Progress 2 (CP2), Regions. Wakame was first recorded in the UK in 1994, where it arrived from the temperate waters of Japan, China and Korea. This is not used to make an oriental laver bread, but nori, the black papery covering of sushi rice. The Feature Activity Sensitivity Tool (FeAST) uses the marine pressure list to allow users to investigate the sensitivity of Scottish marine features. In relation to the marine and coastal environment this includes the protection of migratory species, including birds and fish stocks, protection of marine and coastal habitats, and management of non-native invasive species. The shells are oval or pear-shaped, up to 11cm across. Inter/subtidal. A stock biomass assessment to predict sustainably available annual volumes for each species proposed to be harvested (as an acceptable percentage of standing stock); A sustainable harvesting strategy setting out harvesting methods, the proportion of individual plants or plant populations to be harvested, the frequency of removal, wildlife and habitat disturbance considerations, rotational fallowing. I think increasing plant based meals is also really important. Your feedback helps us to improve this website. It is really important that people eat healthy and that they understand and appreciate the story of where their food comes from. In this guide, we reveal 10 of the most common seaweed types found on UK shores. In fact, one of the great pleasures of studying seaweeds is the many other species that you find along the way. The main species harvested in biomass terms is egg or knotted wrack. However, the groups also differ in more complex structural and biochemical features, such as their photosynthetic pigments and cell structure. When it gets to a certain size, its oxygen-filled body is sufficiently buoyant to lift the unfortunate oyster from the seabed and float off with it. scientific literature through a combination of long-form articles, regular columns and reports, The sea is becoming more acidic as it absorbs increasing amounts of carbon dioxide in our atmosphere. This makes all UK beaches - rocky, shingly or sandy - a good place to forage for them. Below the low water mark, increasing depth results in a very rapid decrease in light intensity so that sublittoral (subtidal) species are restricted to a depth range near the surface, known as the photic zone, where light is sufficient for growth. Bright green and grows up to 40cm in length. At Sandy Bay in south Devon, some years ago, I discovered that its mile of very wide sandy beach had disappeared completely beneath an 8in layer of this seaweed. Sugar kelp is often farmed at sea and is used in cosmetics and animal feeds. dredgers used in maerl extraction). This may involve the collection of 'baseline' data and studies to assess the effects. For example, some grow from the base and some grow from the tips, so we harvest them in different ways to allow them to grow back. The total volume of seaweed harvested is recorded to be around 15,000 tonnes. Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. Indeed, one of them is now our production coordinator and he knows everything there is to know about everything! He continues, As we are driven by the tides, harvesting is not a full-time job but by bringing more activity into Wick, which we have started this year, we can offer more stable employment for people as well., Peter adds: When we started, no one had a clue about seaweed. As one schoolboy exclaimed during a demonstration of seaweed cookery I once gave at my daughters school: Yuck, hes making pudding out of snot.. Illustrations of some of these are provided in Figure 1. However, other species are also harvested, in smaller volumes, including (but not limited to) saw wrack ( Fucus serratus), carragheens ( i.e. The species at the center of Scotland's kelp controversy is Laminaria hyperborea. For example, there is known to be an abundance of Ulva sp. High levels of soluble fibre, supporting healthy digestion. Nori Lyudmila Zavyalova/Shutterstock We'll start off with an easy one. The Crofters (Scotland) Act 1993 (as amended) gives crofters access to reasonable use of seaweed under Common Grazings regulations and these rights are attached to particular tenancies. The harvest of seaweed under other circumstances does not require a marine licence, however landowner permission may still be required. Once considered an incomprehensible habit of the Celtic fringe, eating seaweed has now become very fashionable in Britain, if not exactly mainstream. Like a bayleaf, its removed after cooking, its flavour-enhancing glutamates left behind. In addition, invasive species may dominate in niches liberated by loss of native species (Brodie et al., 2014). With a little increase in wave action, other possible communities can be present in a mosaic with the wracks so that continuous dense wracks cover does not occur. They also added two more types of seaweed: dulse and alaria. book reviews and letters. This formed the basis of a multi-billion-dollar industry and Drew-Baker is honoured in Japan with a monument and the impressive title mother of the sea. This small, red seaweed was first recorded in South West England in 1890 having been introduced from Japan. The distribution of this group is likely to have been highly underestimated as it is a less conspicuous intertidal species that does not regularly form a dominant feature/biotope in the available spatial data layers. 3.5.1. 3.13.1. Forms beds in mid-zone of rocky shores. On sheltered shores there are often dense stands, in potentially harvestable amounts, of intertidal wracks. Even if you think you don't know nori, you do: it's the sushi seaweed.. It only takes around an hour and will provide valuable data that can be used to research the effects of environmental change on our seashore communities. Traditionally it has been harvested on the shoreline, by hand. SHORE started harvesting wild seaweed in Caithness in 2016 after some four years of research and planning into how to do so as sustainably as possible. On Monday, the chain became the first major supermarket to stock fresh, edible seaweed, selling 80g punnets of tagliatelle-like sea spaghetti, harvested on the Cornish coast, for 2. Blades are cut from existing plants, leaving the stipe and lower blade intact and able to keep growing. There are a plethora of edible seaweed varieties, from the rather mysterious-sounding native species spiral wrack, Irish moss and gutweed to the Japanese staples of kombu and nori. Figure c: Kelp forest in shallow water, Loch Laxford NatureScot. CLM includes long-form articles, events listings, publication reviews, Also known as: Toothed wrack or saw wrack. You might spot ridges where neighbouring crusts meet. Edible; used as a sugar substitute. ID notes: Forms long undivided blades that are yellow-brown in colour and have ruffled sides. Seaweed also plays a beneficial role in integrated multi-trophic aquaculture systems, where the by-products from one species are recycled to become inputs for another. Harvest may also involve the use of boat and rake. The Brown Seaweeds of Scotland, Their Importance and Applications Authors: O. Aldulaimi Mostafa Rateb University of the West of Scotland Andrew Hursthouse University of the West of Scotland. Distribution: Found attached to rocks or floating in rock pools. Peter tells me: We saw a transformational opportunity to build our own brand using seaweed as a star ingredient. Why is there a row over seaweed harvesting in Scotland? After an assessment has been completed it may be appropriate for an ' EIA-type' process, of Screening, Scoping and Environmental Statement stages to be applied. Widely distributed but less common on the east coast. Mastocarpus stellatus and Chondrus crispus), the channel wrack ( Pelvetia canaliculata), dulse ( Palmaria palmata), pepper dulse ( Osmundea spp.) A range of shellfish has been used in the Scottish Salmon Company trial including: mussels, oysters and queen scallops, each of which has established markets, as well as sea urchins which are less established. Stratification in Response to Exposure. and Alaria esculenta of solid bedrock shores do not occur here. * Macroalgae communities have different composition at different times of year and therefore the timings could change as the demand changes. The majority of red seaweeds are located along the west coast of Scotland, the Inner Hebrides, the west coast of the Outer Hebrides and around Orkney and Shetland. Today seaweed continues to be used in a variety of products. There may, however, be some potential for physical disturbance of the substrate by other devices ( e.g. A3.11 Kelp with cushion fauna and/or foliose red seaweeds, A3.21 Kelp and red seaweeds (moderate energy infralittoral rock), A3.33 Mediterranean submerged fucoids, green or red seaweeds on full salinity infralittoral rock. Coral weed ( Corallina officinalis) Coral weed seaweed. The UK National Ecosystem Assessment ( NEA) Conceptual Framework (2011) identifies intermediate and final ecosystem services and goods/benefits ( Figure 12). Seaweeds in Scotland's coastal waters fall into the following five broad categories: Wracks (rockweeds): large brown seaweeds of the taxonomic order Fucales. Seaweeds, or marine macroalgae, are plant-like organisms that live in coastal areas, usually attached to rocks or other substrates. Care must be taken to keep the holdfast and part of the stipe intact so that plants re-grow for subsequent harvest. Alterations to temperature, pH and sea levels along with several other factors may result in community shifts which have the potential to affect the ecological functions and ecosystem services currently provided by seaweeds (Jackson et al., 2012). There is growing commercial interest in Scotland in the seaweed resource as properties of various species and potential uses in various products are being recognised. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. They are very special places and we are very keen to protect them it is very important to us., Photographs taken from survey sites. 3.7.1. Its fronds form massive fingers that are attached to a flat palm, that, in turn, is attached to an arm with frilled edges. Building resilience to climate change is also a cross-cutting theme. In England commercial-scale extraction of maerl took place in the River Fal between 1975 and 1991, as much as 30,000 tonnes annually ( UK Marine Special Areas of Conservation webpage [10] ).
