2004年4~10月,在苏州澄湖采集翘嘴鱼白样本62尾,对其年龄和生长进行了研究。其体长与体质量的关系为W=7.3×10-6L3.09。用Von Bertalanffy生长模型对澄湖翘嘴鱼白的生长进行拟合,该模型可较好地反映翘嘴鱼白的生长过程及其变化规律。渐近体长L∞=1 091.4 mm,渐近体质量W∞=3.1274×104g。建议提高澄湖翘嘴鱼白最小捕捞规格到体长70 cm。
From April to October 2004, 62 samples of C. albacore were collected from Chenghu Lake, Suzhou, and their age and growth were studied. The relationship between body length and body mass is W = 7.3 × 10-6L3.09. The Von Bertalanffy growth model was used to fit the growth of Chengchuangzuiyu whitefish. The model could well reflect the growth process and its variation of Cichlium japonicus. Asymptotic body length L∞ = 1 091.4 mm, asymptotic body mass W∞ = 3.1274 × 104g. It is suggested to increase the minimum fishing catch of Chenghu alburnus to a body length of 70 cm.
