Fish occurrence at the study site.

Mean±SE fish biomass (g/50m2) estimated at the study site. Minimum fish length (L) per species excludable by cages was calculated by L = FH/PLH where FH = fish height and PLH = proportional length height coefficient. Species in bold can potentially contribute to the differences based on length frequency. Trophic guilds are Her herbivore, Pla Planktotrophic, Car Carnivorous, and Omn Omnivorous.Fish occurrence at the study site.本研究样地估算得到的鱼类生物量平均值±标准误（单位：g/50m²）。各物种可被网笼拦截的最小鱼类体长（L）通过公式L = FH/PLH计算得出，其中FH为鱼体高度，PLH为比例体长高度系数。以粗体标注的物种，依据体长频率特征，可能是造成体长相关差异的潜在因素。营养类群（trophic guilds）的分类缩写如下：Her代表植食者（herbivore），Pla代表浮游生物食性者（planktotrophic），Car代表肉食者（carnivorous），Omn代表杂食者（omnivorous）。本研究样地的鱼类出现情况。
