Even with dedicated aerators, aquaculture farms can experience stress and mortality in culture animals due to low dissolved oxygen concentrations in pond water. Simple tractor-powered aerators offer a quick and portable solution to low dissolved oxygen levels that provides strong emergency aeration and water movement.
Parasite management is crucial for cod farming in Scotland. The main threat comes from parasites with direct or single-host life cycles.
Using intramuscular injection of white spot syndrome virus, study determines number of viral particles associated with the infectious dose.
Translocated shrimp have the potential to carry pathogens to new areas. Shrimp have a tendency to carry persistent infections without showing signs of disease.
Study in Peru that evaluated three food sources for larval pacu shows that water fleas appear to be a cost-effective substitute for artemia.
A selection program can produce channel catfish with smaller heads relative to their body weights to deliver higher dress and fillet yields.
Palm distillate could be an effective substitute for fish oils in catfish diets. It is is a rich source of vitamin E and natural antioxidants.
It is technologically feasible to recover functional muscle proteins and lipids from fish processing byproducts using isoelectric solubilization/precipitation.
Analytical procedures, like measuring water stability of shrimp feed, performed at labs provide more consistent and quantitative results.
While feed conversion ratios are often used as indexes of feed efficiency, they can be misleading as ecological indicators.
