Fish management with respect to length and weight ratio and ecology of river Jhelum

Author(s): Sartaj Aziz
Abstract: Fish growth plays an important role in the economical development of a nation because it is the most important source of protein for the human being. Kashmir is a place which is mostly famous for the freshwater lakes. These fresh water lakes which form the cold sector are famous for fish growth. There are different species found in Kashmir valley. Fauna of the Jhelum River is one of the oldest fauna known to science the first fauna found in the Jhelum River. However through this study length-weight relationship of fishes was established. Length-weight relationship studies of fishes are considered as an important tool for understanding of fish. Length is a linear measure (in centimeter) and the weight of a fish (in gram) is approximately equal to its volume (cubic centimeter). Hence, weight of a fish is a function of length. The relationship can be expressed by the hypothetical law W= aL3. The value of exponent may considerably deviate from the value 3, as most fishes change their form or shape when they grow. This variation from expected weight to the actual weight of individual fish is assessed by analyzing the length weight relationship.
