Despite the importance of certain highly unsaturated fatty acids in osmotic regulation, few studies have been addressed to determine the essential fatty acid requirements for a given species cultured under different salinities. As Galaxias maculatus is a diadromic species, the present study aimed...

Durvillaea antarctica is a brown seaweed that can be located in the Southern Hemisphere and has a high content of polyunsaturated fatty acids and gamma-tocopherol. Aquaculture currently uses vegetable oils for feeding rainbow trout (Oncorhynchus mykiss), but this reduces the omega-3 levels in the...

Atlantic salmon (Salmo salar) were fed 6 experimental dietscontaining three levels of arachidonic acid (ARA) (0.18 g kg(-1), 0.28 g kg(-1) and 0.63 g kg(-1) for low, medium and high levels, respectively) and two levels of vitamin E (150 and 730mgkg(-1) for low and high levels, respectively). At t...

The activity of fish acid proteases is strongly dependent on the pH, and many basic and applied works had focused on researching the pH-profile of digestive proteases using different buffered media. Nevertheless, enzymatic activity is also known to be affected by the ionic strength (IS) of the me...

Aquaculture represents a vital food production industry that contributes to the global economy and fish supplies. Several studies had suggested that changes in the production process, especially those related to nutritional and feeding interventions may have an impact on the final quality of farm...
