The effects of a period of starvation and subsequent refeeding on the weight and length of sea bass, sea bream and rainbow trout reared at 17%o salinity and at different temperatures were investigated. The fish were starved for 3 weeks and then fed ad libitum by hand for 3 weeks in the 3 periods studied. The study provided evidence of the adaptation of the fish to starvation followed by what may be termed compensatory growth once feeding was resumed. The length changes of the fish indicate that the weight gains were due to grojth rather than increases in gut fat deposits or increased water uptake.
