Abstract: Fishing in India is a major Industry and fish production has been on the rise since independence. Catching and processing of fish generates significant amount of solid waste which include head, offal, fins, some bones, skin, viscera, roe and scales. In view of the high nutrient value of fish and its waste the waste generated by sale of the fish, Catla catla in Anantapuram market was collected and it wash air dried for fifteen days and made in to fine powder. 50mg, 100mg and 200mg of this waste was mixed with 150gm of soil and in this finger millet (Eleusina coracana) was grown for forty five days. Measurement of growth of finger millet supplemented with varied concentration of waste has increase the growth of plant and its root. Determination of chemical composition of fish waste has shown that this is a rich source of nutrients and micro elements. Our studies have shown that plant with fish waste also have increased amount of nutrients and micro elements. Hence it can be said that waste of Catla catla is a good supplement to improve plant growth, quantitatively and qualitatively.
