Abstract/ Executive Summary:

In mini earthen ponds, highest growth and survival of H. fossilis was observed at a density of 200/m2. After 28 days rearing in cement cistern 200/m² gave the highest growth and survival. Highest growth and survival was obtained at the stocking density of 200/m² in net cages also. Among the environment tested, pond rearing of C. batrachus showed better growth performance but cement cistern produced highest rate of survival than others. On the other hand, in mini earthen ponds, after 4 months experimental period, 2/m² stocking density produced highest growth and survival but highest production was obtained at the density of 4/m². Moreover, in monoculture of C. batrachus in partitioned pond during 8 months, highest growth and survival was obtained at 4/m² stocking density and a production of 3200 kg/ha was found at the stocking density of 6/m².

Keywords: Catfish, Breeding, shing, magur

Location: BFRI, Mymensingh

Start Date: 01-07-2002

End Date: 30-06-2003

Program Area: Variety and Species

Commodity: Cat fish

Objectives:

Development of mass seed production technique of shing (H. fossilis); to evolve grow-out technique for shing (H. fossilis) and local magur (C. batrachus) on-station and on-farm condition; to develop a technique of polyculture of shing and magur with carps; and to evaluate the economic benefit to introduction of shing and magur in polyculture system.

Methodology:

The larvae of H. fossilis and C. batrachus produced through induced breeding were reared in different rearing condition such as steel tray, cement cisterns and mini ponds. After yolk-sac absorption H. fossilis larvae were stocked in steel trays @ 1000-1500 individuals/m². Natural (Tubifex, zoo-plankton, Artemia) and formulated feeds prepared from locally available ingredients, fed three times daily @ 15-20% of the total body weight. Growth in terms of length and weight and survival were recorded at weekly interval. For production of fingerlings of H. fossilis and C. batrachus, the reared up fry were stocked in cement cistern and in mini earthen ponds @ 100-400 individuals/m². Feeding was done three times daily with Saudi Bangla Shrimp Nursery feed (Starter-2). Polyculture of shing and magur with carps (excluding the bottom feeders) proved as an ideal culture system. Natural food of different layer of a water body was utilized properly.
