With favorable resources, local sources of eggs, availability of fishmeal and qualified labor, Chile has become the world’s top producer of rainbow trout.
Although lobster farming is already established in Indonesia, improvements in feed and nutrition, and seed collection would help the industry expand. The diet of trash fish fed to developing lobsters generates waste and is not conducive to good hygiene or growth.
In the evolution of shrimp farming, white shrimp emerged as the primary species. While some farms in the Americas successfully converted to intensive practices, wide adoption has been limited.
Lobster cage culture has great potential in Indonesia. The current industry consists of about 1,000 small-scale farm units, many of which raise lobsters in polyculture with seaweed and grouper.
Insufficient cooking and improper storage can lead to the proliferation of pathogens in seafood and other foods.
A feed enrichment study showed that dietary lipid source and content of EPA and DHA in the diets of shrimp influenced the fatty acid profiles of their tails.
Fish farmers rear paddlefish as a substitute for bighead carp in more than 10 provinces in China. Limited supply and high fingerling prices limit expansion of production.
Advances in the culture of sea cucumber species are countering the overexploitation of wild populations. Protocols for intensive hatchery production are well established, and juvenile production efficiency has improved.
Spotted wolffish exhibit attractive culture characteristics, including high value, high growth rates at high stocking densities, excellent fillet yield, nonaggressive behavior and few disease problems.
Early efforts at sole culture in Europe were hampered by several technological and disease problems. Improvements in recirculation technology and advances in feed technology have renewed interest in the species.
Digestive enzymes in fish can cause post-harvest tissue degradation, an effect that is most pronounced when connective tissue is affected. Some parasites produce enzymes that make seafood appear unsuitable for human consumption.
Work on the reproduction and larval rearing of southern Brazilian flounder supports the feasibility of flounder culture. Further research will improve weaning and grow-out techniques for the species.
The most important factors in the loss of quality in seafood are nucleotide catabolism and glycolysis. The rates and pathways of nucleotide degradation vary with species and muscle type.
Enzymes are responsible for postharvest changes in seafood that impact product characteristics and reduce value. The odor of seafood is a direct result of enzyme activity.
The National Marine Fisheries Service Manchester Research Station has conducted research to develop aquaculture systems for the production of sablefish.
Taurine can protect against oxidative stress, neurodegenerative diseases and atherosclerosis. It can lower blood pressure and blood cholesterol values.
