Seafood includes fish and other important marine animals. While national meat consumption correlates strongly with indicators like GDP per capita, this correlation is less intense with seafood consumption. Seafood plays a vital role in some poorer states, serving as a significant source of protein and essential nutrients. [1]
It is used industrially in the production of docosahexaenoic acid. [2] Crypthecodinium cohnii is a heterotrophic non-photosynthetic Microalgae . C. cohnii can acclimate a higher docosahexaenoic acid to polyunsaturated fatty acids ratio, [ 3 ] however current studies are trying to increase the volume of DHA production by creating mutant strains.
DHA in breast milk is important for the developing infant. [10] Rates of DHA production in women are 15% higher than in men. [11] DHA is a major fatty acid in brain phospholipids and the retina. Preliminary research has investigated its potential benefit in Alzheimer's disease, [1] [12] and cardiovascular disease, [13] and other disorders. [1]
In 1983 when production was estimated at 78,000 tons p.a., potential production or Maximum sustainable yield (MSY) was estimated at 150,000 tons, yet by 1990 production had exceeded this level by 55,000 tons. [2] In all areas outside the central Lake Kyoga region, fish production increased
Because of their high protein content, large size, rapid growth (6 to 7 months to grow to harvest size), [3] and palatability, a number of coptodonine and oreochromine cichlids—specifically, various species of Coptodon, Oreochromis, and Sarotherodon—are the focus of major aquaculture efforts. Tilapia fisheries originated in Africa and the ...
World capture fisheries and aquaculture production by species group [1] This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.
The Department of Trade and Industry states in its sector diagnostic study, that national aquaculture production data (2003–2006) in 2003 was 3,485 tons and in 2006 was 3,564 tons which had a value of R210. Abalone accounted for the biggest increase with production increasing by 61% from 515 tons in 2003, to 833 tons in 2006.
