Cyanobacteria toxicity tested in shrimp larvae
Often forming large colonies, cyanobacteria – aquatic, photosynthetic organisms – represent one of the largest and most important bacteria groups.
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.
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.
Chloramphenicol revisited
Zero tolerance for chloramphenicol residue in food by the European Community indicates that chloramphenicol risks are regarded as real by European regulators.
Mercury scare: Conflicting reports affect U.S. seafood attitudes, consumption
U.S. news media, doctors and even dietitians are warning patients that methylmercury in fish can harm them, their children and their unborn children.
Researchers capture images for practical molt stage analysis in shrimp
Many production aspects in shrimp culture are related to the molt stage, such as mating in closed-thelycum species, market value and eyestalk ablation.
Stressors in fish culture decreased through dietary manipulation of arachidonic acid
Studies show that dietary arachidonic acid improves fish survival and growth if offered together with suitable levels of the other essential fatty acids.
Levels of dietary gossypol affect growth, bacterial resistance of Nile tilapia
Dietary gossypol from cotton seeds, if present in large amounts in a diet, causes unfavorable physiological effects in monogastric animals including fish.
Development of DNA vaccine for piscine mycobacteriosis
