CENAIM study examines effects of transport on shrimp postlarvae survival
The cumulative effects of shrimp hatchery harvest, packing, temperature change, transporting and acclimation have an impact on postlarvae survival.
Concerns over antibiotics, chemicals in aquaculture
When an antibiotic is administered, the usual effective dose may be insufficient to control an infection if the invasive microorganism has developed resistance.
Size-grading experiments yield strong advice for tilapia hatcheries
In an experiment in which tilapia were sorted by size and reared separately, large individuals maintained their size advantage after eight weeks of culture.
Israeli study examines feeding regimes for Asian sea bass grown at high temperatures
Asian sea bass (Lates calcarifer) feeding strategies and diets must be developed for slow-growth (winter) and fast-growth (summer) seasons.
Intensively cultured Paraclanid copepods for small tropical marine fish larvae?
Intensively cultured Paracalanid copepods represent a valuable new diet for rearing small tropical marine fish larvae under biosecure conditions.
Netherlands study links fish feeding behavior with growth performance
Do fish grow differently because of variations in growth efficiency or social hierarchies that affect the feeding behavior in tanks or cages?
Penaeus vannamei seedstock production
The dramatic transformation of the shrimp sector in Asia was fueled by the switch from monodon shrimp to P. vannamei seedstock from Hawaii.
Cyanobacteria toxicity tested in shrimp larvae
Often forming large colonies, cyanobacteria – aquatic, photosynthetic organisms – represent one of the largest and most important bacteria groups.
New nursery diet for shrimp performs well at super-high stocking densities
A shrimp diet developed in trials is the first dry nursery diet shown to ensure good performance at stocking densities up to 45,000 per square meter.
Diagnostic profile of Belize Taura Syndrome Virus
Shrimp farming in Belize, Central America, was hard hit by Taura Syndrome Virus (TSV, now known as TSV serotype A) in 1996 and a re-emergence in 2002.
Trans-fatty acids health concerns, labeling requirements
FDA’s regulatory definition for trans-fatty acids is all unsaturated fatty acids that contain one or more isolated double bonds in a trans configuration.
Genetic screening in Nile tilapia
Both microsatellite and AFLP marker analyses can provide adequate screening of genetic diversity in tilapia stocks at a low cost.
Feed ingredient digestibility
Determining the digestibility of protein and other nutrients in feed ingredients is an important step in the formulation of balanced feed.
Super chilling slurry ice quickly cools, preserves seafood
Slurry ice is widely adopted in major fisheries around the world, where ice companies work with fishermen and seafood processors to develop better methods of preservation.
SPF-defined pathogen-free status of shrimp limited
Specific pathogen-free status depends on the presence or absence of specific pathogens. This status depends on the level of biosecurity for the shrimp.
Mexican institute studies dried artemia biomass as feed for postlarval shrimp
Dried artemia biomass and other crustacean meals could be cost-efficient alternatives for shrimp hatcheries as the only feed used to rear shrimp postlarvae.
