摘　　要：于2021年4—5月从德清昊源水产种业有限公司按照人工繁育标准挑选后,随机采集卵巢发育处于Ⅳ期的一龄和二龄马口鱼(Opsariichthys bidens)雌性个体60尾,开展个体繁殖力研究。结果表明,平原池塘养殖条件下马口鱼体重与全长的关系为W=0.0061L3.2092,其中一龄马口鱼的绝对繁殖力(F)在749.33~6070.20粒,平均为3209.74粒;体重相对繁殖力(FW)在49.62~244.67粒·g^(-1),平均为142.03粒·g^(-1)。二龄马口鱼的绝对繁殖力(F)在2178.13~7530.60粒,平均为4400.17粒;体重相对繁殖力(FW)在42.75~148.83粒·g^(-1),平均为90.68粒·g^(-1)。一龄马口鱼体重相对繁殖力极显著高于二龄马口鱼(P<0.01)。本研究表明,一龄马口鱼雌鱼亲本较二龄马口鱼雌鱼亲本具有更高的繁殖性能。The individual fecundity of Opsariichthys bidens was studied based on 60 one-year old and two-year old female individuals according to artificial breeding standards with ovaries atⅣstage from Deqing Haoyuan Fish Farm during April and May in 2021.The results showed that the relationship between body weight and full length in plain pond cultured O.bidens could be described with the function of W=0.0061L3.2092.The absolute fecundity for one-year old female individuals ranged from 749.33 to 6070.20 eggs(average 3209.74 eggs).The relative fecundity in body weight for one-year old female individuals ranged from 49.62 to 244.67 eggs·g^(-1)(average 142.03 eggs·g^(-1)),respectively.The absolute fecundity for two-year old female individuals ranged from 2178.13 to 7530.60 eggs(average 4400.17 eggs).The relative fecundity in body weight for two-year old female individuals ranged from 42.75 to 148.83 eggs·g^(-1)(average 90.68 eggs·g^(-1)),respectively.The relative fecundity in body weight for one-year old female individuals was found to be extremely significantly higher than two-year old female individuals(P<0.01).This study indicated that one-year old female individuals have higher reproductive performance than two-year old female individuals.
