Aquafeeds
A study evaluated the potential of pink salmon testes meal, a fisheries byproduct, as a feed ingredient to replace fishmeal in diets fed to juvenile Pacific threadfin. Results showed the salmon testes meal contained high levels of protein, taurine and arginine.
Aquafeeds
A study investigated the effects of storage temperature and duration on the quality of finished fishmeal fed to juvenile shrimp. Diets with 15 percent fishmeal were stored at 4 or 30 degrees-C for six months or 12 months.
Aquafeeds
A study of shrimp feeding demonstrated the digestibility of byproducts prepared from salmon livers, salmon milt, black cod viscera and arrowtooth heads and viscera from Alaskan fisheries processing plants.
Health & Welfare
New cost-effective additives, such as fishery byproducts, will likely be needed to meet the increasing demand for feeding stimulants by aquafeed producers.
Health & Welfare
An eight-week growth trial evaluated the effects of potassium diformate on the growth performance and digestibility of Pacific white shrimp. Weight gain was not significantly affected by different levels of PDF in diets, and survival was high for all treatments.
