New WSSV, TSV genotypes identified in Saudi Arabia
To determine origins of White Spot Syndrome Virus and Taura Syndrome Virus in Saudi Arabia, authors performed genotyping studies and found a new genotype in each of the isolates collected.
Fish protein hydrolysates enhance stress resistance of aquaculture species
Fish protein hydrolysates are naturally rich in nutrients that can help support aquatic species’ immune defenses in resisting stressors.
Studies identify aquaculture potential for Cortez flounders
Preliminary studies at the University of Sonora showed that wild Cortez flounders readily adapted to captivity and accepted dry feeds. Results of this work encourage further investigations of its potential for aquaculture.
Malaysian mahseer: New candidate for Asian aquaculture?
There is much interest in the biology and artificial propagation of the Malaysian mahseer, both for conservation and aquaculture production.
Effective management of WSSV in shrimp
As research on WSSV continues, commonsense steps can lessen the potential impacts of white spot syndrome virus on shrimp-farming operations.
Integrated spotted red snapper aquaculture in Central America
The technology for closing the life cycle of spotted red snappers has progressed due to efforts of government and private-sector researchers.
Dietary potassium diformate improves growth performance of male Nile tilapia
Some of the more promising alternatives to antibiotics for the treatment of Nile tilapia are found in the group of organic acids and their salts.
Fishery byproducts evaluated as feeding stimulants in plant-based shrimp diets
New cost-effective additives, such as fishery byproducts, will likely be needed to meet the increasing demand for feeding stimulants by aquafeed producers.
Nitrogen isotope for evaluating protein uptake in biofloc systems
Measurements of nitrogen isotope uptake can enable more efficient study of feed utilization in whole aquaculture pond systems.
A case for better shrimp nutrition
Shrimp farm performance can often be below realistic production standards. Use proven nutrition, feeds and feeding techniques to improve profitability.
Research supports healthy fish skeletons
Deformities in farmed fish skeletons can result from excessively fast growth, high temperatures, insufficient calcium and phosphorus, and other factors.
Integrated aquaponics systems evaluated for arid zones of Chile
Integrated aquaponic operations can improve water use efficiency because plants participate in nitrogen and phosphorus removal and integration.
Study: Lower biofloc concentration may improve shrimp production
In an experiment comparing two biofloc concentrations, shrimp grew larger and faster in low-solids, with no significant differences in survival, FCR or final biomass.
Hybrid catfish offer performance advantages for U.S. farmers
Hybrid catfish offer production advantages over channel catfish. Trials show greater survival, faster growth and shorter production cycles.
Tilapia aquaculture in China
Sustainable development of China's tilapia industry depends largely on the market prices of products, disease control, climate and seed availability.
Why certify aquaculture?
In the international aquaculture trade, producers have lots of information on how their fish or shrimp were produced, but buyers may know little about a product’s safety, origins or environmental and social impacts.
