Abstract

North eastern region (NER) of India harbours 266 species of fishes out of which 196 have potential ornamental value. The present paper incorporates the technique of mass propagation of indigenous ornamental fish species with Danio aequipinnatus as the test species. For successful mass propagation of D. aequipinnatus, selection of brood stock, food and feeding schedule and breeding set-up are important criteria. Maintenance of physic-chemical parameters of the breeding tank is important in the survival of the breeders. Best fertilization rate are obtained with 3:2 male to female ratio.

Highlights

The hobby of keeping ornamental fish has expanded into a booming international trade. 85% of ornamental fish from north eastern region are exported to the global market and all are traded on wild catch
Looking at the present scenario of ornamental fish trade of North eastern region (NER), the present paper accentuates the technique of mass propagation of indigenous OFS D. aequipinnatus a classified ornamental fish of NER in particular for the benefit of entrepreneurs in ornamental fish trade [3]
Live food consisted of mosquito larva, blood worm and tubifex which were supplied at the rate of 6% and 5% per body weight respectively at every 8 hours and formulated feed were supplied at the rate of 8% per body

Summary

Introduction

The hobby of keeping ornamental fish has expanded into a booming international trade. 85% of ornamental fish from north eastern region are exported to the global market and all are traded on wild catch. The hobby of keeping ornamental fish has expanded into a booming international trade. 85% of ornamental fish from north eastern region are exported to the global market and all are traded on wild catch. The commercial organized export of freshwater ornamental fish depends primarily on assured and adequate supply as and when demand arises [1]. Some studies have been done by the earlier workers on food, nutrition and rearing of some ornamental freshwater fishes viz., 18; 11; 14; 2 and 17. It was 7; 15; 16 and 13 who made empirical studies on the breeding of some native ornamental fish species of N.E. India hitherto remain [2]. Looking at the present scenario of ornamental fish trade of NER, the present paper accentuates the technique of mass propagation of indigenous OFS D. aequipinnatus a classified ornamental fish of NER in particular for the benefit of entrepreneurs in ornamental fish trade [3]
