Preventing melanosis in shrimp
The black spots of melanosis quickly arise in harvested shrimp from enzymatic reactions in shrimp tissue or external stressors.
Sole larvae perform best on algae-and-rotifer diet
In a study, Senegal sole larvae had better survival when fed an initial diet of enriched rotifers with algae, rather than artemia alone.
Controlled cooking methods offer higher shrimp yields with product safety
Advances in equipment design keep pace to provide uniform, controlled cooking temperatures that allow more precise bacteria lethality with higher yields.
Polyculture studies with white, black tiger shrimp show promise in Indonesia
The Central Pertiwi Bahari farms in Indonesia found polyculture of white shrimp and black tiger shrimp at a density of 70 PLs per square meter promising.
Tilapia harvest microbial flocs in active suspension research pond
In a study, microbial flocs contributed about 50 percent of feed material as dry solids and about 50 percent of the protein requirement of tilapia.
Florida study achieves tank spawning of southern flounder
Southern flounder offer potential in aquaculture to answer declining fishery landings and increased demand, but insufficient fingerlings are available.
Australian research examines effects of hatchery cleaners, procedures on oyster embryos
A recent study showed the sensitivity of Sydney rock oyster embryos to small amounts of disinfectants and other substances commonly used in hatcheries.
Field diagnostic kits for aquaculture
New antibody-based diagnostic kits for aquaculture disease diagnosis are simple and fast, and high-sensitivity PCR testing is coming to the field, as well.
Advances in tank culture of sunshine bass fry
The successful development of efficient tank culture techniques for sunshine bass fry and fingerlings would help in the year-round production of fish of uniform size and quality.
P.L. size, source strong early measures of shrimp grow-out performance
Artificial diets are used to replace live artemia at commercial shrimp hatcheries, but complete replacement remains a challenge for strong grow-out results.
Seaweed products find varied commercial, medical applications
Seaweed products like extracts are ingredients in many beauty products and creams, and widely marketed as natural herbal and weight-reduction products.
Flatworms potential harvesters of antitumor compounds
Tiger flatworms hold promise as a source for ecteinascidins, a class of antitumor compounds under study for human cancer treatment.
Nutrient requirements of penaeid shrimp
Penaeid shrimp need the same nutrients required by all animals, including protein, lipids, energy sources, vitamins, minerals, oxygen and water.
Oxygen injection system helps manage D.O. in salmon cages
A commercial oxygen injection system tested in Norway maintained D.O. at levels that sustained growth and increased the harvested biomass.
Quality Index Method provides objective seafood assessment
The Quality Index Method provides guidelines for objectively assessing seafood freshness with specific criteria for individual species.
Scombrotoxins, part 3
While freezing, salting, smoking and irradiation can minimize growth biogenic amine formation, special care from harvest through consumption can prevent scombrotoxin poisoning.
