Worldwide inland fish culture industry is suffering from massive economic losses due to epizootic ulcerative syndrome (EUS) and fish-based pathogens. The available literature indicate that infection from fish pathogens like bacteria ( Aeromonas hydrophila and Aeromonas sobria ), fungi ( Aphanomyces invadans ) and viruses can cause stunted ...
In 1988 the fish catch was 302,900 tons. In 1991 the catch was 289,675 tons, down from more than 319,000 tons in 1990. [1] Large-scale poaching by foreign vessels has severely depleted fish stocks in Ghana's 200-nautical-mile (370 km) maritime Exclusive Economic Zone, causing major government concern. [1]
Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
In 2016, the greatest part of the 12 percent used for non-food purposes (about 20 million tonnes) was reduced to fishmeal and fish oil (74 percent or 15 million tonnes), while the rest (5 million tonnes) was largely utilized as material for direct feeding in aquaculture and raising of livestock and fur animals, in culture (e.g. fry, fingerlings ...
Aquaculture (less commonly spelled aquiculture [1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus).
Biofloc technology (BFT) is a system of aquaculture that uses "microbial biotechnology to increase the efficacy and utilization of fish feeds, where toxic materials such as nitrogen components are treated and converted to a useful product, like a protein for using as supplementary feeds to the fish and crustaceans."
Fish play symbolic roles in religion, mythology, folklore, and fairy tale, where stories about fish have been told in cultures around the world for thousands of years. Fish have similarly been depicted in art, literature, film, and music in many cultures. Academic study of fish in culture is called ethnoichthyology. Both academically and in ...
