【摘要】 测定了黄颡鱼的体长、头长、吻长、眼径、眼间距、眼后头长、头高等形态指标。雌性个体的体长显著小于雄性个体,雌雄两性个体头长、吻长、眼间距、眼后头长随体长的增长呈同速增长,无显著差异。雌性个体在眼径、头高随体长的增长速度显著大于雄性个体。更多还原

【Abstract】 We measured some morphological traits, including the body length, head length, length of proboscis, diameter of eye, eyes interval, head length behind the eyes, and head height of Pseudobagrus fulvidraco. Female body is notably shorter than male body. The head length, length of proboscis, diameter of eye, eyes interval, head length behind the eyes of male and female individuals grow at the same speed at which the body length grows, with no remarkable difference. Female individual’s diameter of eye and head height grow at a remarkably greater speed than male individuals.更多还原
