Fish censuses are important tools used by researchers and resource managers to evaluate an ecosystem's health, to identify and maintain viable fish populations for the future, and to determine human impacts on current fish numbers. A variety of methods, both invasive and noninvasive, have been tried and tested to help estimate fish populations. The effectiveness and reliability of each of these census techniques are dependent upon various circumstances and conditions specific to each environment in which they are used. The purpose of this paper is to review the literature and then evaluate the censusing methods most appropriate for commercial fisheries, scientific research, and the aquaculture industry.
