The effect of dietary water content and feeding rate on the growth and food conversion efficiency of turbot (Scophthalmus maximus L.)

The effect of dietary water content and feeding rate on the growth and food conversion efficiency of turbot was investigated using diets which contained identical amounts of dry nutrient material but different quantities of water, ranging from 0 to 74 per cent. The dietary water content did not significantly influence the growth, composition, condition factor or food conversion efficiency of the turbot. It appeared that, as long as the basic nutrients were formulated so as to produce an adequate diet, the water content was immaterial. The over-riding factor governing growth was the rate of food intake. Comparisons at feeding rates which in energy equivalents ranged from 24 to 72 calories per gram of fish a day, showed that the higher the energy intake the more rapid the growth. At the highest feeding rate, fast growth was accompanied by a marked increase in the condition factor and an elevated lipid content of the fish. The percentage protein content, however, was relatively stable in relation to the feeding rate. Food conversion efficiency was also relatively stable. On average, 40.3 per cent of the dietary protein and 36.3 per cent of the ingested energy was converted into turbot
