Abstract/ Executive Summary:

Mature meni (N. Nandus) of about 6-8 months age were selected for breeding and females were introduced with hormone extract @ 5 mg/kg body weight. At the same time males were introduced PG @ 2 mg/kg of body weight. Ovulation was taken place after 6-7 hours and hatching successful was about 100%.

Keywords: Breeding, Culture techniques, Bheda (Nandus nandus)

Location: Santahar, Bogra, Mymensingh, Faridpur & Jamalpur

Start Date: 01-07-2001

End Date: 30-06-2002

Program Area: Variety and Species

Commodity: Fish

Objectives:

To develop economically and socially viable breeding and culture technology of Bheda; and to develop and adopt viable small scale aquaculture technology of Bheda

Methodology:

About 150 mature meni fish (N. nandus) were collected from beels of Faridpur and Jessore region and reared in ponds of Santahar Sub-station. Both female and male breeders were injected with 3 different doses of PG @ 1-3, 2-4 and 3-5 mg/kg of body weight. After injection, both male and female breeders were placed in spawning hapa (1:1). Ovulation and natural spawning accomplished within 6-8 hours after injection. The newly produced hatchling than shifted to shallow cisterns for nursing. Larval rearing of meni hatchlings in cemented cisterns were continued for a period of 2-3 weeks. After yolk sac absorption, the fries fed with chopped tubifex and zooplankton. Than they were shifter to earthen pond for further rearing.
