Abstract
Most of the usual methods for studying fish populations have been ineffective when applied in the shallow, freshwater marshes of southern Florida. Exceptions are devices which trap fish by rapidly enclosing a known area of marsh. Of these, pull‐up traps are best suited for sampling large areas for relatively large or widely dispersed fish, whereas drop traps with bottom nets are the most efficient for studies of small species at permanent sampling sites. Each produces comparable but consistently biased results due to habitat disturbance. The most precise data on shallow water fish communities are obtained by use of bottomless drop traps which are moved to new sites for each sample.This publication has 0 references indexed in Scilit:
