The synergistic effect of arachidonic acid (ARA) (20:4n-6) and alpha-tocopherol on the accumulation of fatty acids and the peroxidation of lipids in liver and muscle was evaluated in Atlantic salmon (Salmo salar) juveniles. Triplicate groups were fed during 12 weeks with eight experimental diets ...

A digestibility trial was conducted to assess the effect of dehulling, steam-cooking and microwave-irradiation on the apparent digestibility of nutrients in white lupin (Lupinus albus) seed meal when fed to rainbow trout (Oncorhynchus mykiss) and Atlantic salmon (Salmo salar). Six ingredients, wh...

Intestinal inflammation is a harmful condition in fish that can be triggered by the ingestion of soybean meal. Due to the positive costs-benefits ratio of including soybean meal in farmed fish diets, identifying additives with intestinal anti-inflammatory effects could contribute to solving the i...

'Puye' (Galaxias maculatus) is a small freshwater fish species of great interest to Chilean aquaculture diversification, because of the high commercial value reached by its transparent larvae or 'cristalino'. This study presents the first data with regard to blood cytology in larvae and adults of...

Two feeding experiments were conducted to investigate the effect of a low-phosphorus (P) diet in combination with citric acid (CA) on rainbow trout growth performance and P utilization. In the first 12-week trial, duplicate groups of 30 fish (12.0 +/- 1.7 g) were fed one of five diets. The basal ...

The products resulting from the non-enzymatic browning in processed diets are known to exert negative effects on the digestive enzymes of vertebrates. In addition, browning heavy products (BHP's) are known to co-precipitate with proteins depending on the pH and ionic strength of the medium and on...

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...
