Distribution of Larval Fishes in a Lower Mississippi River Dike Field

A study was conducted from April through October 1980 to characterize seasonal changes in distribution, diversity, and abundance of ichthyoplankton within the Cracraft dike field in the lower Mississippi River. During high river stages (April through June), diversity and abundance of larval fishes were greater at open-water than nearshore stations. Under moderate to low river stages (July through October), diversity was low and greatest densities of larval fishes were observed along the shoreline inside the middle bar rather than in the open-water.
