Study on Freshwater Snail (Viviparus viviparus, Linnaeus): Culture Techniques at the Farmers Level and Its Potential to Use in Fish Feed Formulation - Softcover

Inhaltsangabe

In the inland aquaculture systems, traditional aquaculture started shifting from the culture of piscine to non-piscine aquatic animals in Bangladesh. The present study was concerned with emerging culture systems of freshwater snail, (Viviparusviviparus) at the farmers level highlighting its potential to use in fish feed formulation. The study was conducted over a period of 7 months from May to November 2009 in Rupal Integrated Farm Chothrasia, MuktagachaUpazila of Mymensingh district. Emerging culture systems of freshwater snail, its collection methods, proximate composition of snail mixed feed and comparative economic efficiency of snail mixed feed versus traditionally used fish feed were the focal points under the present study.The pond for freshwater snail culture was rectangular in shape with an area 120 decimals. After liming at the rate of 1-1.5 kg/decimal, pond was filled up with water where compost manure was spread throughout the pond during noon. Then snail seeds were stocked. After 15days of interval, compost was provided to the pond for satisfactory growth and breeding of snails. The collection of snail from the culture ponds were carried out by the four methods.
