Immunostimulant qualities of probiotic bacteria
The use of probiotic bacteria and immunostimulants are promising yet controversial methods to prevent and manage infectious shrimp diseases.
Scope for further optimization of selective breeding in aquaculture species
Article briefly describes the structure of family-based selective breeding and identifies areas where developments in genetics and related fields may increase efficiency.
Dietary cottonseed meal affects growth, hematology, immune responses of Nile tilapia
Cottonseed meal is less expensive than soybean meal, and studies have explored whether it can be incorporated in fish diets without affecting growth performance.
Salinity affects protein, lipid requirements of Nile tilapia broodstock
United Arab Emirates University studied the effects of salinity and dietary protein levels on spawning performance of Nile tilapia broodstock.
L. vannamei trials in Indonesia improve productivity
In L. vannamei trials in Indonesia, results confirmed that somewhat lower protein levels in feed had no effect on production performance.
Temperature affects sperm quality in L. vannamei
A Texas A&M study showed that temperature affects sperm quality of Pacific white shrimp, the top commercial shrimp species in the Americas.
Study shows oxytetracycline controls streptococcus in tilapia
The FDA approved the oxytetracycline to combat streptococcosis in aquaculture, but their use is limited to channel catfish and salmonid species.
Channel catfish seedstock: Studies yield suggestions for hatching success
Research indicates that small improvements in current management practices can significantly improve the hatching success of channel catfish.
Sex-reversal technology in sustainable aquaculture
Sex-reversal in cultured fish can be easily controlled – females grow more than males and mature later – because the process of gonadal differentiation is very labile.
Tagging technology helps monitor shrimp performance in research, genetic improvement
A variety of external and internal tags have been developed over the past several decades to enable researchers to monitor aquatic animals.
Thai study shows fatty acid profiles of tilapia vary by aquaculture system
University of Stirling study determines the fatty acid profiles for Oreochromis niloticus tilapia and hybrid red tilapia in Thailand.
Supplemented feeds stimulate immune systems of gilthead sea bream
Gilthead seabream (Sparus aurata) is affected by winter disease, a complex syndrome that has been related to cold stress-induced immune suppression.
Carotenoids, retinoids modulate ovarian development in Litopenaeus vannamei
The levels of carotenoids in commercial shrimp feeds are generally insufficient to reach the physiological levels needed for critical bioactive functions.
Canthaxanthin stands up to scrutiny
Carotenoids like canthaxanthin are biological pigments widely found in nature that provide color to many species of birds, insects, crustaceans and fish.
Management of seafood safety and quality systems in Irish aquaculture
Two key supports of Irish aquaculture are provided by state agencies through the development of product quality and food safety programs.
Thailand works to prevent problems in exported aquaculture products
Thailand is one of the top shrimp exporters but if it is to retain confidence in the safety and quality of its products, significant measures must be taken.
