Age and Growth Related Investigations on Major Carps in the Riverine Environment of River Ghaghra at and Around Faizabad

Abstract

A considerable population of India is suffering from malnutrition. This problem can be solved up to some extent when we add fishes in our food. Fishes are good source of protein and vitamins. To ensure the availability of fishes to masses we have to improve the production in our available water resources. Rivers in India are a good source of freshwater fish production. Ghaghra is an important river of North India. It has sufficient water around the year. The present investigation was carried out to observe the comparative growth of Cirrhinus mrigala,Labeo rohita,Labeo calbasu and Catla catla in riverine environment of Ghaghra.The back-calculation method was adopted to assess the age and growth of these fishes. It was observed that the growth rate of Labeo calbasu is maximum among above four fishes.
