根据1994年的汤河水库鲢、鳙的生物学测定、历年的放养数量和历年的渔获量资料,对汤河水库鲢各龄鱼的残存率、资源量进行了估算(鲢、鳙比例接7：3原则确定),从而确定了鱼种规格为132mm时的最佳放养数量为3．246753×106尾(其中鲢为2．272727×106尾；鳙为9．74026×105尾)。在连续8～10年无任何捕捞时水库对鲢、鳙的环境容纳量为2．246124×106尾(其中鲢为1．572287×106尾；鳙为6．73837×105尾)。依据RICKER模式确定了鲢、鳙的最佳捕捞死亡系数分别为2.0和1．9,最佳开捕年龄分别为5和4．5龄,同时确定了1994年汤河水库偷鱼量为5．0×104～6．0×104kg,从而提出了汤河水库渔业资源的合理利用策略。
Based on the biological measurements of silver carp and silver carp in Tanghe Reservoir in 1994, the stocking quantity over the years and the catch data over the years, the survival rates and resources of fish at various ages in the Yuhe Reservoir were estimated 7: 3 principle to determine), so as to determine the fish stock size 132mm when the best stocking number is 3.246753 × 106 tail (which silver carp is 2.272727 × 106; 鳙 9.74026 × 105 tail). In 8-10 years without any fishing, the environmental capacity of silver carp and bighead carp in the reservoir was 2.246124 × 106 tails, of which silver carp was 1.572287 × 106 tails and 鳙 6.73837 × 105 tails. According to the RICKER model, the best fishing mortality index of silver carp and bighead carp were 2.0 and 1.9, respectively. The best catching age was 5 and 4.5 years old, respectively. 0 × 104 ~ 6.0 × 104kg, so as to put forward the reasonable utilization strategy of the fishery resources in Tanghe Reservoir.
