Enumeration of Fish or Other Aquatic Animals

  • Robert G. Wetzel

There are various ways of estimating the size of a natural population of large, mobile animals in a freshwater habitat. Obviously, the most accurate method would involve catching or, in some way, counting the entire population. However, this approach is usually either impossible to do in practice or, at least, destructive to the natural populations. Instead, a mark-and-recapture procedure frequently is used to obtain a statistical estimate of the size of the natural population.
