摘要

1965年,在弗吉尼亚州东岸半岛的海滨码头进行勘探调查期间,通过浅水围网运输获得了幼鱼白鲻鱼(Mugil curema Valenciennes)的分布、生长和捕食水平数据。从6月到9月,每半个月的平均最小生长量为17.5毫米。用模拟计算机拟合的生长方程为:Wt=615(1−e−0.78t)3 Lt=360(1−e−0.78(t+0.06))叉长单位为毫米,重量单位为克。9月下旬进水口采食时,捕食率最高,为49%。文献资料表明,出现在北卡罗莱纳北部的幼年白鲻鱼有南方的起源。

Distribution, growth, and predation of juvenile white mullet (Mugil curema) in oceanside waters of Virginia’s eastern shore
Distribution, growth, and predation level data for juvenile white mullet (Mugil curema Valenciennes) were obtained in 1965 by shallow water seine hauls during an exploratory survey of oceanside embayments of Virginia’s eastern shore peninsula. Average minimum growth was 17.5 mm fork length per half-month period, June through September. Growth equations fitted with an analog computer are: Wt=615(1−e−0.78t)3 Lt=360(1−e−0.78(t+0.06)) Fork lengths are in mm and weights are in grams. Highest predation incidence, 49%, was observed in late September inlet collections. Literature data implies juvenile white mullet, that occur north of North Carolina, have a southern origin.
