The role of fish hatchery is to produce healthy and high quality fry or fingerlings in sufficient numbers according to the operation plan of the hatchery. Therefore and in reference to the “compensatory growth” phenomenon in fish, hatcheries are not supposed to produce large-size fingerlinger on the cost of their number (unless economically justified). In grow-out on fish farms, hatchery-produced normal size fry or fingerlingrlings are expected to show exceptional grow rate compared to their larger-size counterparts of fingerlings and over time, the will be able to make up the deficit in average weight and hence minimizing initial benifit of producing unnecessarily large-size fingerlings on the cost of larger numbers of healthy even smaller size fingerlings.
