feed conversion ratio("Feed conversion ratio (FCR) is calculated from the number of kilos of feed that are used to produce one kilo of whole fish." visitor)
yield potential(Yield potential is affected not only by the coregonid species stocked, but by both abiotic and biotic environmental conditions and by factors intrinsic to the population in question... Once the manager is satisfied that the general conditions are favourable he needs to consider the relationship between the yield potential, life stage and stocking rate in determining the target catch from the fishery. For example if in an eutrophic lake the target is to increase the whitefish catch by 1 kg/ha then the target could be achieved by stocking 323 ( = 1 000/3.1) larvae or 38 (= 1 000/26.3) summer juveniles or 15 (= 1 000/66.7) autumn juveniles. Yield (kg/l 000 fish stocked) from coregonid stockings by life stages in oligotrophic (Finnish) and in eutrophic (Polish) lakes. Alexander Demidov)
efficiency of stocking(количество исходного рыбопосадочного материала (икра, личинки, мальки, сеголетки), которое необходимо иметь для того, чтобы через определенное число лет в промысел вступила одна взрослая особь. The efficiency of stocking (yield per unit stocked) for tilapia was not significantly related to ...| The efficiency of stocking was considered in terms of yield per unit stocked (Welcomme & Bartley 1998). Alexander Demidov)
stocking efficiency(The stocking efficiency (ratio of the yield of stocked fish in kg/ha to the weight of the stocked fish in kg/h) in reservoirs in ThaiNguyen Province ... Alexander Demidov)
instantaneous growth rate(a measure of the weight increase, the natural logarithm of the ratio of final weight to initial weight of a fish in a unit of time, usually a year Cranberry)
conversion rate(Коэффициент расхода сырья (переводной коэффициент) – это показатель выражающий отношение количества израсходованного сырья к количеству готовой продукции.aldrignedigen)
