Krill meal use reduces other costly ingredients in shrimp study diets
Due to its high protein and highly unsaturated fatty acids content, krill meal can be an effective ingredient in aquafeed.
Much of Brazil’s expanding tilapia aquaculture takes place in floating cages with sturdy frames and nets made from plastic-coated steel or polypropylene.
Due to its high protein and highly unsaturated fatty acids content, krill meal can be an effective ingredient in aquafeed.
Determining dietary requirements for tilapia requires precise formulation. Individual amino acids must be considered to establish well-balanced diets.
Cobia is a top emerging candidate for tropical and subtropical marine fish aquaculture. The University of Miami Experimental Hatchery has led ongoing research to advance the viability of raising hatchery-reared cobia.
With the global spread of viruses, biosecurity has become an essential element of every shrimp farm. Biosecurity starts with quality of farm design.
Research with sturgeon and carp species indicated that encapsulated artemia has high potential to carry probiotics or other beneficial microorganisms.
In studies, bacteria and yeasts isolated from the native microbiota of wild shrimp at larval, juvenile and adult life stages were administered to early-stage shrimp via the culture water.
Advances in fish hatchery management – particularly in the areas of brood management and induced spawning – have helped establish aquaculture for multiple species.
Published information on the effects of including organic acids and their salts at low concentrations in aquafeeds varies according to fish species and age, as well as the types and levels of organic acids and salts used.
A study in Brazil found that the growth superiority brought about by within-family selection of tested shrimp transmitted to the next generation of animals.
Traditionally, Australian farmers relied on wild broodstock to source black tiger shrimp larvae, but substantial progress has been made in the domestication and selective breeding of Australian P. monodon.
The basic premise of refrigeration is to move heat from a colder heat source to a warmer heat sink. Common pitfalls for refrigeration in aquaculture are a lack of water flow, inadequate evaporator capacity and evaporator freezing.
In research involving white shrimp siblings raised in ponds in Thailand and in raceways in Hawaii, shrimp growth can be improved after one generation of selection, even with a modest investment.
Authors examined whether beta-glucans extracted from bakers yeast could improve the survival and growth of Pacific white shrimp challenged with infectious myonecrosis virus.
In an NHP (necrotizing hepatopancreatitis) challenge test, shrimp from a Colombian breeding program had higher resistance and 30 percent greater survival than a control line of Taura syndrome virus-free shrimp.
Although concerns for the animal welfare of food animals are currently highest in the United Kingdom and European Union, they are also growing in other parts of the world.
