Organisms generally increase in size (length, weight) during development. The key factors
that influence the growth of fish are the quantity of food available, the number of fish utilizing
same food source, temperature, oxygen and other water quality factors besides the size, age
and sexual maturity of the fish. Every animal in its life exhibit growth both in length and in
weight and the relationship between these two has both applied and basic importance. The
length-weight relationship is one of the standard methods that yield authentic biological
information and is of great importance in fishery assessments. It establishes the mathematical
relationship between the two variables, length and weight, and helps in assessing the
variations from the expected weight for the known length groups
