| 摘 要： | 2010年5月10日-6月20日对黑龙江同江至抚远江段的施氏鲟（Acipenser schrencki）捕捞群体结构进行调查，测量施氏鲟90尾，全长为96～201（150.53±18.93）cm；其中雌性个体全长为 113～201（163.14±22.24）cm；雄性个体全长为96～183（138.48 ±20.55）cm。体重为3～44（18.46±10.17）kg；其中雌性个体体重为7.5～44（24.48±10.33）kg；雄性个体体重为3～30.5（12.70±5.94）kg。繁殖群体的雌雄比例为1:1.05；以16～20龄个体为主，占捕捞群体的37.2%；优势群体在11～25龄，占总群体的84.7%。繁殖群体中雌性的生长方程为:Y=0.00129x3.3169 ,R2=0.9202 ，雄性的生长方程为: Y=0.0029X3.0899, ;R2=0.9375 。 |

| Abstract: | A survey on the population structure of Acipenser schrencki in the Amur reach between Tongjiang City and Fuyuan County was conducted from May 10 to June 20 in 2010,and 90 fish of A.schrencki were measured,full length being between 96 and 201 cm,with average length(150.53±18.93) cm.Of 90 fish,full length of individual female was 113-201 cm,average length(163.14±22.24) cm;full length of individual male was 96-183 cm,average length(138.48 ±20.55)cm.The individual body weight was 3-44 kg,average weight(18.46±10.17) kg.The weight of individual male 7.5-44 kg,average weight(24.48±10.33) kg;The weight of individual female 3-30.5 kg,average weight(12.70±5.94)kg.The ratio between female and male of the breeding population was 1:1.05;individuals of age 16-20 were of dominance,representing 37.2% of the catch.Dominant individuals were 11-25 years of age,constituting 84.7% of the total.Growth equation of female in breeding population is y=0.001x3.3169,R2=0.9202,whilst growth equation of male in breeding population is y=0.0029x3.0899,R2=0.9375. |
