Abstract

An adaptive trial was undertaken for early breeding of carps in four private hatcheries of Khordha district in the state of Odisha, India. CIFABROODTM, a promising carp brood diet was used to observe the breeding performance and seed production of carps in early monsoon. CIFABROODTM was provided in experimental ponds while farm made feed prepared by the hatchery owners were used in the control ponds. After 45days of feeding, fishes in the trial ponds became mature while in the control ponds fishes were immature. Average fertilization rate was observed to be 88.14% with an average spawn recovery of 2.14 lakh spawn/kg body weight of female. Highest average fertilization rate was found in mrigal followed by rohu and catla. Similarly average spawn recovery per kg of female body weight indicates a highest recovery in rohu followed by mrigal and catla. In turn the spawn buyers had an average survival rate of 42.18% from spawn to fry and 73.5% from fry to fingerling rearing. This adaptive trial has reconfirmed CIFABROODTM as a proven carp brood diet which has shown to impact at all the three crucial stages of seed production. The positive outcomes of the attributes of innovation were highly towards an increased rate of adoption.

Highlights

Aquaculture is considered as one of the booming sector in India providing livelihood to millions of farmers
The network of hatcheries comprised of public and private sectors in India has grown substantially but the position to meet the demand of quality seeds is not encouraging
The study tailored towards understanding the status of hatcheries, capacity to hold the trial and perception of hatchery owners towards off season fish seed production

Summary

Introduction

Aquaculture is considered as one of the booming sector in India providing livelihood to millions of farmers. Though the technique of carp seed production (induced breeding and multiple spawning) is well standardised3,4.5,6,7 the availability of quality seeds is one of the major impediments in expansion of aquaculture in India. Lowering of temperature even without rainfall will bring about ovulation or spermiation in Indian major carps which is the rationale behind CIFRI’s early breeding programme of both major and exotic carps in different seasons[10] In this context, ICAR-Central Institute of Freshwater Aquaculture conducted research and developed a brood stock diet ‘CIFABROODTM’ for early maturation of broods and producing quality seeds. CIFABROODTM, as a brood stock feed advances maturation and growth of gonads, facilitating early spawning and significantly increases spawning response This may be due to increase in the level of prostaglandin and sex steroids estrogens and progesterone[21]. This study was conducted with the objectives to analyse the performance of CIFABROODTM at farmer’s field through adaptive trial, to study the attributes of the innovation and to understand the perception of hatchery owners and fish seed buyers on off season fish seed production
