中文摘要:
      为了研究小黄鱼形态性状与体质量之间的关系,以小黄鱼的体质量和8个形态性状(全长、体长、头长、躯干长、尾长、尾柄长、尾柄高及体高)为对象,进行形态性状与体质量的灰色关联分析,以此衡量各形态性状对体质量的相对重要性。结果显示,小黄鱼雌性个体生长速度显著大于雄性个体。所有目标性状中,体质量的变异系数最大(雌性:30.598%;雄性:27.055%),形态性状之间的变异系数相差不大(雌性:9.941~12.543;雄性:8.170~13.295)。小黄鱼的雌雄样本中,形态性状与体质量的灰色关联度存在一定差异,其中,雌性样本的形态性状与体质量的关联度在0.526 6~0.681 2之间,关联度从高到低依次为:全长 > 体长 > 躯干长 > 尾长 > 尾柄长 > 体高 > 尾柄高 > 头长;而雄性样本的关联度在0.528 4~0.711 6之间,关联度依次为全长 > 体长 > 尾长 > 躯干长 > 尾柄长 > 尾柄高 > 体高 > 头长。8个形态性状在雌、雄样本中均是全长与体质量的关联度最高,体长次之,头长最低,而其余性状在雌、雄样本中的排序存在一定差别,研究结果为小黄鱼良种选育方案的制定提供了重要指导。
英文摘要:
      The small yellow croaker(Pseudosciaena polyactis) is an important marine fish species and widely distributed throughout the Bohai Sea, the Yellow Sea, and the East China Sea of the Northwest Pacific Ocean. Grey relational analysis was used in this study to examine the relationship between morphological traits and body weight of the small yellow croaker. Body weight and 8 morphological traits(including total length, body length, head length, trunk length, tail length, caudal peduncle length, caudal peduncle depth, and body depth) were measured and analyzed. The results show that the average body weight of female was significantly greater than that of male. The coefficients of variation in body weight(30.598 for female, 27.055 for male) were greater than morphological traits(9.941-12.543 for female, 8.170-13.295 for male). The grey relational degrees between morphological traits and body weight were in the interval of 0.5266-0.6812 for female, 0.5284-0.7116 for male. The descending relational order of the morphological traits in the female samples was total length > body length > trunk length > tail length > caudal peduncle length > body depth > caudal peduncle depth > head length. That of male samples was total length > body length > tail length > trunk length > caudal peduncle length > caudal peduncle depth > body depth > head length. In all the samples, the grey degree of total length was the highest and followed by body length, and the head length was the lowest both in the female and male. This study provided scientific basis for the small yellow croaker breeding selection on growth traits.
