Abstract

In Fisheries Science the word stock is defined as a sub-set of one species having the same growth and mortality parameters, and inhabiting a particular geographical area. Most of the parameters in the stock assessment cannot be obtained or measured throughout the whole population. In fish population studies, it is impossible to measure the whole population and also the fish caught. Hence a sample of the population is collected assuming that a reasonable estimate can be obtained of the true value of the sample population. Random sampling can be defined as a sampling from a population where each entry has an equal chance of being drawn. In practical terms this means that any fish from the stock under investigation have the same probability of being sampled. Care should be taken to sample from a mixed or unsorted catch of commercial landing.
