Vertical underwater farming of kelp and shellfish. Many types of seaweed are edible. You also have the option to opt-out of these cookies. This work will help lead to more efficient permitting and allow seaweed farming to expand while also being economically and environmentally sustainable. [27], Spreading of pathogens between fish stocks is a major issue in disease control. Kelp farming has gotten a lot of attention, and WHOI scientists and collaborators have developed a selective breeding program designed to produce strains that are high-yield and more resilient to a warming ocean. Diagram of a seawater greenhouse: the humid conditions inside the greenhouse is created by the evaporation of seawater at the front of the building at the seawater surface through porous cardboard. Their blades will reach 10 feet or more before they are harvested in the spring. Saltwater, instead of freshwater, can be used to directly support a wide range of sustainable agricultural activities and enrich the soils in the coastal regions. In fact, dense seaweed farms can create a halo-effect around them that could help mitigate local ocean acidification. Existing pilot projects are running independently in Eritrea (Seawater Forest Initiative), Mexico (Seawater Foundation, Bahia Kino), the United Arab Emigrate (UAE University) and Australia (Seawater Green House). He managed to make a successful transition into shellfish farming in the Long Island Sound until he was all but ruined again when powerful hurricanes demolished his oyster crops two years in a row. Seawater Farming - Seawater Solutions For these reasons, environmental organizations such as the World Wildlife Fund and The Nature Conservancy actively champion shellfish and seaweed farming. Offshore aquaculture, also known as open water aquaculture or open ocean aquaculture, is an emerging approach to mariculture (seawater aquafarming) where fish farms are positioned in deeper and less sheltered waters some distance away from the coast, where the cultivated fish stocks are exposed to more naturalistic living conditions with stronger ocean currents and more diverse nutrient flow. Seaweed farming can offset some of the serious problems facing the oceans. By continuing on this site, you consent to their use. As a fisherman in Newfoundland, Bren Smith (TEDxBermudaTalk: The least deadliest catch) saw his livelihood vanish when the Atlantic seaboards cod stocks collapsed in the 1990s after years of overfishing. She lives in New York City. Aquaculture regulations vary from country to country. It receives everything it needs from the sun and the sea. Aquaculture is the farming of aquatic animals or plants principally for food. Some of the challenges in the U.S. thus far include regulatory and policy hurdles (e.g., the need to secure permits to farm in state and federal waters), as well as a reluctance by more established commercial and recreational interests to share the marine environment. Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater, or a mixture of fresh water and seawater.There are crops that can grow on seawater and demonstration farms have shown the feasibility.

He wondered: What if we could take a vertical approach to aquaculture? [14] However, new species are now being farmed offshore although little is known about their ecology and epidemiology. Here on Cape Cod (and in other regions in the U.S.), oyster farming has greatly expanded in the last decade, and some private and municipal shellfish programs are expanding with the aim of using shellfish production and harvests to mitigate excess nitrogen in estuaries. The UN estimates that the world could easily be fed if just 2% of oceans were used for sustainable farming. Summer 2018. Subscribe to Salt of the Earth, our monthly newsletter! It includes the breeding, rearing, and harvesting of fish, mollusks, crustaceans, and plants in fresh and saltwater environments. [26], Compared to inshore aquaculture, disease problems currently appear to be much reduced when farming offshore. Farmers grow various types of seaweedincluding dulse, bull kelp, ribbon kelp, and sugar kelpthat are used in sushi, salsas, sauces, salads, seasonings, and other food products. However, some issues remain with seawater farming: Japan for Sustainability. "[31], Moving aquaculture offshore into the exclusive economic zone (EEZ) can cause complications with regulations. Fortunately, the U.S. has one of the most stringent water quality monitoring, testing, and shellfish food safety systems in the world which prevents accidental harvest and sale of HAB-impacted shellfish. Seawater Solutions develops degraded coastal land using seawater, creating wetlands that capture carbon, create jobs, produce food, re-wild the environment, clean waterways and stabilise coastlines. WHOI scientists are developing new robotic vehicles and modifying existing ones in order to develop a system to autonomously sample and monitor offshore aquaculture production. For shellfish and finfish farmers, commercial fishermen, and first-time farmers, seaweed offers an opportunity to diversify a farming operation or start a new business. Biofuels from land-based sources such as corn and sugarcane require arable land, fertilizers from fossil fuels, and scarce fresh water, whereas biofuels from marine algae and seaweeds require only sunlight and abundant seawater.

There is no shortage of sea-water: 97 percent of the water on earthis in the oceans. [7] Employment is likely to expand more at processing facilities than grow-out industries as offshore aquaculture develops. The seaweeds create forage and refuge habitat for commercially important fish and diversity of marine life. Although existing federal statutes provide a framework for regulation, critics say that state regulations for different kinds of aquaculture vary considerably and that there is no way to ensure that regulations are uniformly enforced. Rich nutrients from sea-water are used to grow saline-tolerant, profitable species such as white-leg shrimp (Penaeus vannamei), Indian prawn (Penaeus indicus), tilapia fish and milk-fish (chanos chanos). [2][3] Existing "offshore" developments fall mainly into the category of exposed areas rather than fully offshore. Unlike land-based crops, seaweed is what Smith calls "zero-input food" it requires no additional fresh water, fertilizer, pesticides, feed or soil to grow. For shellfish and finfish farmers, commercial fishermen, and first-time farmers, seaweed offers an opportunity to diversify a farming operation or start a new business.

The practice originated in China about 4,000 years ago, and global production continues to be dominated by China and other Asian countries. Dickenson, M (July 10, 2008). Another major challenge identified by the research community is the need to routinely monitor aquaculture farmsa difficult task if farms are located offshore. We need more farms. [2] This could have significant consequences for native species, even if the farmed fish are inside their native range. Artistic rendering of floating ocean farms designed by Agrisea. Known as "seawater rice" because it's grown in salty soil near the sea, the strains were created by over-expressing a gene from selected wild rice that's more resistant to saline and . Sustainable Seafood: An Interview with Janet Coit, NOAA Fisheries Assistant Administrator. Moving aquaculture offshore also provides more ecological space where production yields can expand to meet the increasing market demands for fish.

In Puget Sound, bull kelp has declined extensively. Seaweed farming can offset some of the serious problems facing the oceans. [16] Future offshore farms will probably be much larger than inshore farms today, and will therefore generate more waste. Except for a few countries, offshore aquaculture has focused predominantly on high value carnivorous fish. M.A. Historically, freshwater aquaculture (particularly carp and catfish) has been and continues to be responsible for the majority of global production. Learn . Traditional methods of fishing or aquaculture wont work under current conditions we need a 21st-century strategy. What I realized then was, this isnt a slow lobster boil of climate change, Smith says. "Shellfish farming is very sustainable. Kelp is one of the fastest-growing organisms on the planet. Growing crops underwater also benefits the environment by eliminating the need for pesticides as no pests can enter the pods unless they are introduced. This means farmers can grow seaweed using a process known as vertical, or 3D, farmingand reap large harvests from a small area. Right out of the ocean it does, just like any other fertilizer that is not diluted properly; but delivered in the proper concentration seawater is actually an amazing fertilizer. Farming seaweed is an efficient way to produce highly nutritious food for a growing population. For example, farmers in Alaska produced more than 112,000 pounds of sugar, ribbon, and bull kelp in 2019. Seawater Farming.
