The ichthyoplanktonic community of Tamiahua Lagoon, Veracruz, Mexico, was studied throughout an annual cycle. Major concentrations of larvae occurred in the central portion of the lagoon, occasionally along the channels, but never at the inlets. The cycle of larva abundance was correlated with cycles of salinity and temperature. In spite of the greater number of species then, the spring and summer periods had low species diversity and evenness, due to the marked domination by larvae of Anchoa mitchilli. The number of larval fish species and individuals entering the lagoon from the adjacent offshore waters was minimal. The greatest portion of species diversity is generated within the lagoon itself. The community structure identified corresponds to the physically controlled type, as indicated by the poor diversity values obtained.

墨西哥西部海湾塔米亚瓦泻湖浮游鱼类的季节性多样性，丰度和分布。

在整个年度周期中，研究了墨西哥韦拉克鲁斯州塔米亚瓦泻湖的鱼鳞浮游生物群落。幼虫主要集中在泻湖的中央部分，偶尔沿着通道出现，但从未出现在入口处。幼虫丰度的周期与盐度和温度的周期相关。尽管有更多的物种，但春季和夏季的物种多样性和均匀性较低，这是由于due鱼的幼虫明显占优势。从邻近近海水域进入泻湖的幼体鱼种和个体数量很少。物种多样性的最大部分是在泻湖内部产生的。如获得的差的多样性值所表明的，所识别的群落结构对应于物理控制的类型。
