WebMark and Recapture Technique In this procedure, biologists use traps to capture animals and mark them in some way. The animals are then returned unharmed to their environment. Over a period of time, the animals are trapped again, with researchers recording how many of the original tagged individuals are recaptured. WebMark and recapture is a process where a small group of a particular fish species is captured, marked or tagged, and then released so they can be recognized during a later recapture. These methods help scientists better understand the numbers and distributions of fish populations. 2. Introduce the fish mark and recapture simulation activity.

WebManagers can use “Mark-Recapture” techniques to estimate population size without handling every individual in a population. Calculating a population estimate requires two sampling visits. During the first visit (the “marking period”), the sample crew will collect as many individuals as possible in a standardized time period.
