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.
Although researchers in several countries are working to enhance sea urchin fisheries or commercial production, the development of a major commercial industry has been restrained by the lack of cost-effective production technology.

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.
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.
There is much interest in the biology and artificial propagation of the Malaysian mahseer, both for conservation and aquaculture production.
As research on WSSV continues, commonsense steps can lessen the potential impacts of white spot syndrome virus on shrimp-farming operations.
The technology for closing the life cycle of spotted red snappers has progressed due to efforts of government and private-sector researchers.
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.
New cost-effective additives, such as fishery byproducts, will likely be needed to meet the increasing demand for feeding stimulants by aquafeed producers.
Measurements of nitrogen isotope uptake can enable more efficient study of feed utilization in whole aquaculture pond systems.
Shrimp farm performance can often be below realistic production standards. Use proven nutrition, feeds and feeding techniques to improve profitability.
Deformities in farmed fish skeletons can result from excessively fast growth, high temperatures, insufficient calcium and phosphorus, and other factors.
Integrated aquaponic operations can improve water use efficiency because plants participate in nitrogen and phosphorus removal and integration.
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 production advantages over channel catfish. Trials show greater survival, faster growth and shorter production cycles.
Sustainable development of China's tilapia industry depends largely on the market prices of products, disease control, climate and seed availability.
