Precision fermentation is a method that uses tiny living things called microorganisms to create specific molecules. This process can make food ingredients usually found in animals and plants, such as proteins, fats, sugars, and other substances. Microorganisms like bacteria or yeast are used to make large amounts of a particular compound.
Recirculating aquaculture systems (RAS) are used in home aquariums and for raising fish when water exchange is limited. These systems use biofiltration to reduce harmful ammonia levels. Other types of filtration and environmental controls are often needed to keep water clean and create a good home for fish.
Integrated multi-trophic aquaculture (IMTA) is a farming method that uses waste, such as leftover food or animal waste from one type of water creature, as resources for another. Farmers grow animals that need to be fed (like fish or shrimp) together with plants (like seaweed) and animals that filter water (like shellfish) to create systems that help the environment, improve farming results, and make farming practices more accepted by communities. Choosing the right types of animals and plants, and controlling how many of each are grown, helps create a balance in the ecosystem.
Integrated multi-trophic aquaculture (IMTA) is a farming method where waste and other byproducts from one aquatic species are used as resources, such as food or fertilizer, for another species. Farmers combine farming of animals like fish and shrimp with farming of seaweed and shellfish to create balanced systems that help protect the environment, improve economic results, and support better farming practices. Choosing the right species and managing their numbers helps maintain a stable balance in the ecosystem.
Seaweed farming, also called kelp farming, is the process of growing and collecting seaweed. Some farmers collect seaweed from natural areas, while others grow it in controlled environments where they manage every stage of its growth. The seven most commonly farmed types of seaweed are Eucheuma spp., Kappaphycus alvarezii, Gracilaria spp., Saccharina japonica, Undaria pinnatifida, Pyropia spp., and Sargassum fusiforme.
Integrated multi-trophic aquaculture (IMTA) is a method of farming aquatic animals and plants where waste and other byproducts from one species are used as resources for another. Farmers grow animals that need food (like fish and shrimp) together with plants and animals that take in nutrients (like seaweed and shellfish). This creates systems that help the environment, support economic growth, and improve farming practices.
Tilapia is the third most important fish in aquaculture, following carp and salmon. Global production of tilapia exceeded 1.5 million metric tons in 2002 and continues to grow each year. Tilapia is farmed widely because it has high protein content, grows quickly (reaching harvest size in 6 to 7 months), and is easy to eat.
Shrimp farming is a type of aquaculture that happens in saltwater or freshwater areas, where shrimp and prawns (types of crustaceans) are raised for people to eat. However, this industry has caused problems, including harm to mangrove ecosystems, the use of slave labor, and issues related to how the animals are treated.
Salmonid aquaculture involves farming and harvesting salmonid fish, such as salmon and rainbow trout, under controlled conditions for commercial and recreational use. Salmonids, along with carp and tilapia, are the three most important fish groups in aquaculture. The Atlantic salmon (Salmo salar) is the most commonly farmed salmonid for commercial purposes.
Dolphin-safe labels are used to show that fishing methods follow laws or rules meant to reduce the number of dolphins that die when catching tuna for canning. Some labels have stricter rules than others. The Dolphin Safe label started in the United States.
