Harike wetland (Ramsar site) is an internationally important aquatic ecosystem. This water body is widely known for its commercial fishery resources as many fishermen and their families are dependent on this for their livelihood. Fishery resources from natural aquatic ecosystems are depleting with a very fast pace due to various anthropogenic activities. Harike wetland possessing wide array of fish biodiversity but the important commercial fishes are depleting with a very fast rate due to loss of habitat, discharge of industrial effluents, municipality sewerages, pollution from surface runoff, addition of solid waste, etc. It is observed that the catch of commercial fish Catla catla is depleting drastically from this wetland hence study of length-weight relationship has been conducted to know the present status of the fish. The coefficient correlation (r) was found to be 0.94 indicating a significant linear relationship of length and weight. The exponent value b = 3.2028 was indicating positive allometric growth from this wetland.
