Induced breeding of Vietnam koi (Anabas cobojius, Hamilton, 1822) under controlled conditions at Murshidabad district, West Bengal

Vietnam koi, a new variety of exotic koi, native to Vietnam getting tremendous popularity in different parts of West Bengal due to its quick increase in body weight. Murshidabad Krishi Vigyan Kendra under take programme on popularization of new breed air-breathing fish through demonstration programme during 2014 to 2015. By culturing this species farmer’s were getting 150g to 200g body weight within 3-4 months and the market price of was Rs. 250-300 per kg. Realizing the huge demand of quality fish seed, KVK Murshidabad successfully under took the breeding programme of this species at KVK farm. In this breeding programme gonadoprim hormone used as inducing agents in different doses i.e. 0.25ml, 0.30ml, 0.35ml kg-1 of body weight for male and 0.35ml, 0.45ml, 0.50ml kg-1 of body weight for female. Among the different doses 0.45 ml kg-1 of ...

Larval rearing of freshwater Angelfish (Pterophyllum scalare) fed on different diets

The mean survivable rate (%) after 20 days observation were 74.67% for Artemia, 68.33% for rotifer, 70.89% for Moina, 29.46% for Ceriodaphnia, 31.19% for egg custard and 23.72% for green water (Table.3.1). The survivable rate (%) is greater in Artemia than Moina, rotifer, egg custard, Ceriodaphnia and green water respectively. The highest growth rate 11.1 mm was observed in case fed by Artemia after 20 days of culture and lowest 4.8 mm was found in Ceriodaphnia (Table.3.2). The average 28 days required for live feed taken by the spawn cultured, maximum 36 days and minimum 24 days required respectively and diseases occurrence also observed during this study.

Low Cost Innovative Technology for Seed Production of Cirrhinus Reba (Hamilton, 1822) at Backyard of Murshidabad District, West Bengal, by using Ovaprim

The optimum dose of Ovaprim (0.3 ml/kg of body weight for male and 0.5 ml/kg for female) were standardized based on three experiments, viz., fecundity (relative fecundity), and response time (hrs) and fertilization rate at different doses. Maximum fecundity (9120) obtained at 0.5 ml/kg of body weight. Hatching conducted in a specially designed inverted at 2 liter thumps up bottle following the mechanism of glass jar hatchery and the spawns are reared at nursery pond by placing the hatchlings in the hapa. This innovative and cost effective technology will certainly add a new era in the seed production of Cirrhinus Reba including some other indigenous fishes of fresh water sector.

The optimum dose of Ovaprim (0.35ml/kg of body weight) was standardized based on three experiments, viz., fecundity (relative fecundity) at different doses (r = - 0.94; p< 0.01, n = 6), response time (hrs) at various doses and fertilization rate (r = -0.69; p<0.01; n = 6) at different doses. Maximum fecundity (665.66) obtained at the dose of 0.35ml/kg of body weight and a significant relation was observed between doses and response time (hrs.) of spawning at 1% level (F = 189.14; p<0.01; n = 6). Lower breeding response time recorded at this dose.

Assessment of productivity of pangas catfish (Pangasius pangasius, Hamilton-1822) culture in jute retting pond in Murshidabad district

But few farmer’s, they were culture traditionally with IMC and exotic carps and getting very low yield (3.66q ha-1yr-1). In that condition Murshidabad KVK has designed one OFT trails having three treatments, Farmer’s Practice (FP), Technology Option-I (TO-I) and Technology Option-II (TO-II) on air-breathing fish pangas (Pangasius pangasius) and conducted in farmers’ field for three years. To find out the suitable fish species, observed water parameters (pH, DO mg L-1), stocking density (nos./ha), length (cm), weight (g), survival rate (%), yield (q ha-1yr-1), cost of culture (Rs. ha-1yr-1) gross return (Rs. ha-1yr-1), net return (Rs. ha-1yr-1), BC ratio and disease incidence etc. The effect of water pH and DO (mg L-1) in post jute retti...
