Fisheries :: Integrated Farming System | ||
Seri-Fish System In this integration, mulberry is the producer; silkworm is the first consumer while fish is the secondary consumer, ingesting silkworm faeces directly. Inorganic nutrient in the silkworm faeces are utilized by phytoplankton, and filter-feeding fish in turn consumes heterotrophic bacteria. The optimum range of temperature and humidity is 15-32oC and 50-90% respectively. The seri-fish system provides linkages between mulberry and pond sub-system. Harvested mulberry leaves are fed to silkworm and the waste material obtained from silkworm rearing enters fish-pond as a mixture of mulberry leaves and silkworm excrement. Mulberry dykes yield leaves at 30 tonnes/ha/year, when fed to silkworm 16-20 tonnes of waste is produced. In 1 ha mulberry-pond system, 50% of area is kept for dyke and remaining is kept as water area. During winter, vegetables are inter-planted with mulberry. A production of 30 tonnes of mulberry-leaves/ha, 3.75 tonnes of vegetables/ha can be attained.
