Biosecurity principles for sustainable production using SPF shrimp
Basic components of biosecurity include knowledge of diseases, adequate detection methods and the use of “clean” shrimp stocks.
Disease risk evaluation
Assessing disease risk at an aquaculture facility allows the anticipation of possible outbreaks and subsequent production losses. It can also help to identify weaknesses of the production system.
International coalition breaks cobia fingerling production bottleneck
Fingerling production has long been a bottleneck in the advancement of cobia culture. A coalition has validated intensive larviculture production systems and protocols that deliver 35 percent survival.
Soy-based diets support white shrimp performance
A study evaluated Pacific white shrimp given plant protein-based diets with varied lipid content and soybean meal:soy protein concentrate ratios.
Candidate gene markers for selective breeding of CyHV-3-resistant carp, koi
Common carp and koi producers around the world have suffered substantial financial losses due to a contagious disease caused by cyprinid herpesvirus-3.
What makes bioflocs great for shrimp?
Single-celled proteins in bioflocs can provide protein and other nutrients in shrimp feed, but what makes them enhance growth performance in shrimp?
Intensive nursery, pre-grow-out of white shrimp in autotrophic, heterotrophic systems
A seven-week trial evaluates autotrophic and heterotrophic systems in the nursery and pre-grow-out of Pacific white shrimp.
Developing a breeding program for Tasmanian salmon
A research partnership focused on Atlantic salmon selective breeding aims to improve growth and resistance to amoebic gill disease in Tasmanian salmon.
Sensory analysis evaluates pangasius fillet quality
Authors developed a lexicon of sensory properties for pangasius fillets and examined the sensory characteristics of raw fresh and frozen catfish fillets as predictors of the sensory qualities of cooked catfish.
New approaches can help ensure safety of raw farmed oysters
Practical post-harvest oyster processing methods are needed. Preliminary studies evaluated the potential of high-salinity relaying to control Vibrio levels in raw oysters.
Innovative techniques achieve more cost-efficient salmon selective breeding
Successful non-invasive predictions of pigment and fat levels in whole salmon were demonstrated by the authors using visible and near infrared spectroscopy to study how these traits vary genetically during growth.
Parasitism enhances susceptibility to bacterial infection in tilapia
The authors conducted a study to evaluate whether tilapia infected with Gyrodactylus were more susceptible to Streptococcus iniae. The research found that fish with a solo infection of Gyrodactylus or Streptococcus had less than 7 percent total mortality.
Intensive Peruvian operation produces shrimp in greenhouses
Langostinera Florida is an intensive shrimp farm with controlled conditions. Greenhouses can operate in areas where diseases have affected the industry.
Tilapia aquaculture in Saudi Arabia
Saudi Arabia has a growing aquaculture industry that farms mainly tilapia, but also shrimp, grouper, sea bream, rabbitfish and mullet. Although aquaculture is a major source of supply for fresh fish, it has not grown fast enough to meet the country’s growing demand.
Farmed tilapia net producers of long-chain omega fatty acids
In a trial, a novel dietary vegetable oil blend was able to totally replace fish oil in tilapia diets without negatively impacting growth performance.
New Bacillus probiotic tested for shrimp
The authors evaluated Bacillus bacteria in a pink shrimp nursery and found it controlled Vibrio concentrations as well as a commercial probiotic.
