Despite the well known importance of omega-3 polyunsaturated fatty acids (PUFA) in marine and freshwater fish larvae, there are few studies on how essential fatty acid requirements and composition on whole body can be altered by changes in water salinity. The present study aimed to determine the ...

This study was conducted to evaluate the effect of citric acid (CA) and amino acid chelated trace elements (AA) on the growth, phosphorus (P) utilization efficiency and loading in rainbow trout fed a diet formulated with a low-fish meal (FM) concentration. A low-FM basal diet with or without mono...

Artificial diets have been reported to produce suboptimal pH values in the stomach of salmonid species. Therefore, it is interesting to investigate the gastric function of different species fed commercial diets. In the present work, two groups of Atlantic salmon juveniles were either fasted or fe...

Melanoidins, a product of advanced browning reactions due to the thermal treatment of the diet, has been previously demonstrated to inhibit the activity of trypsins from mammalian origin, but no data exists in relation to fish trypsins. The present work is devoted to the investigation of the effe...

In a global context of a fast growing aquaculture, the reduction of the aquatic pollution through the optimisation of aquafeeds and their nutritional value is a major concern for farmers, researchers and governments. More than 50% of phosphorus (P) reserves in seeds of most legumes are stored as ...

Melanoidins are complex molecules usually found within dietary matrixes suffering heating steps during the production process. These compounds are known to exert a number of negative effects on the digestibility of nutrients and digestive enzymes in mammals, but also determines an increase in the...

Whole lupin seed meal was evaluated as partial replacement for fishmeal in extruded diets for rainbow trout, with particular emphasis on the effect on growth performance and apparent digestibility coefficient (ADC) of protein, lipids, carbohydrates, and energy. Effect on muscle fatty acid composi...

The use of macroalgae as an additional component in animal feeding has been studied. However, information on how it could influence muscle composition of fish body is scarce. This study evaluates four diets with different macroalgae inclusion levels (0%, 1.5%, 3% and 6%) to test the effect on bod...
