Effect of different levels of poultry droppings on growth performance of Indian major carps in the foothills of Arunachal Pradesh, India

Abstract

This study was conducted to evaluate the effect of different level of poultry droppings on growth performance of Indian major carps (IMC) during May 2013 to April 2014. Three ponds viz. T0,T1 and T2 having an area of 1000 square meters were selected for the study and stocked at the rate of 10,000 fingerling/ha with Catla catla (Hamilton), Labeo rohita (Hamilton) and Cirrhinus mrigala (Hamilton) in the ratio of 3:3:4. The T1 and T2 ponds were supplied with poultry excreta from 70 and 90 numbers of broiler birds respectively, except the T0 (control) pond. Growth per day of Catla catla, Labeo rohita and Cirrhinus mrigala were 1.59 g, 1.16 g and 0.83 g in T1; 1.87 g, 1.49 g and 1.15 g in T2 and 0.70 g, 0.51 g and 0.41 g in T0 pond respectively. The T1 (55.24%) and T2 (66.28%) ponds showed higher fish production compared to T0. Higher yield of the T2 pond indicated the optimum amount of poultry droppings compared to T1. The water qualities in all ponds were falling in suitable ranges. Judicious amount of poultry droppings were favoured the better yields of fish by maintaining desired level of water quality for aquaculture in foothills of integrated fish- poultry farming (IFPF) system.
