In a 10-week study of nursery-reared Pacific white shrimp performance, the inclusion of Spirulina meal allowed reduction of fishmeal up to 25 percent with no detrimental effect on shrimp growth performance.
The authors have established a procedure to reduce the impacts of Taura Syndrome Virus in the culture of Pacific white shrimp. The procedure focuses on avoiding the molting process of shrimp by limiting culture conditions.
Waddell Mariculture Center operates a commercial-scale prototype raceway utilizing minimal water exchange and biofloc culture to develop protocols for the indoor growout of Pacific white shrimp.
In biofloc production systems, ammonia-oxidizing bacteria process ammonia to nitrite, which provides substrate for nitrite-oxidizing bacteria that process nitrite to relatively non-toxic nitrate.
A study carried out with the herb punarnava showed that it has antiviral properties in resisting WSSV infection and holds potential to promote growth in tiger shrimp. Increased survival was related to higher dosages.
In order to monitor and compare the performance levels of shrimp, statistical modeling of comprehensive field data collection from many commercial shrimp operations.
Probiotics administered in feeds provide competitive exclusion of pathogenic bacteria, create conditions unfavorable for pathogens and modulate intestinal immune responses.
A study demonstrated that VP19 and VP28 white spot syndrome virus envelope proteins expressed by replicon particles provided protection against mortality due to WSSV in shrimp.
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.
Basic components of biosecurity include knowledge of diseases, adequate detection methods and the use of “clean” shrimp stocks.
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.
A study evaluated Pacific white shrimp given plant protein-based diets with varied lipid content and soybean meal:soy protein concentrate ratios.
Common carp and koi producers around the world have suffered substantial financial losses due to a contagious disease caused by cyprinid herpesvirus-3.
Single-celled proteins in bioflocs can provide protein and other nutrients in shrimp feed, but what makes them enhance growth performance in shrimp?
A seven-week trial evaluates autotrophic and heterotrophic systems in the nursery and pre-grow-out of Pacific white shrimp.
A research partnership focused on Atlantic salmon selective breeding aims to improve growth and resistance to amoebic gill disease in Tasmanian salmon.
