Hello Sir
there are 3 types u can start semi intensive and extensive type
In extensive fish farming, economic and labour inputs are usually low.
Natural food production plays a very important role, and the system’s productivity is relatively low.
Fertiliser may be used to increase fertility and thus fish production.
Semi-intensive fish farming requires a moderate level of inputs and fish production is increased by the use of fertiliser and/or supplementary feeding. The fish are fed supplementary feed, while natural food production plays a minor role.
To start with
Ponds may be dug into the ground; they may be partly above or below original ground level. Slopes and bottom should be well
packed during construction to prevent erosion and seepage. Soil should contain a minimum of 25% clay.
Depth should be 0.5-1.0 m at shallow end, sloping to 1.5-2.0 m at the drain end.
Best shape for ponds is rectangular or square.
Sufficient water should be available to fill all ponds on the farm within a few weeks and to keep them full throughout the growing
season.
The steps in building a fish pond are:
1 Prepare the site
2 Build a clay core (in the case of contour ponds)
3 Dig the pond and build the dikes
4 Build the inlet and outlet
5 Protect the pond dikes
6 Fertilise the pond
7 Fence the pond
8 Fill the pond with water
9 Stock the fish
Combination of rohu and a fish with complementary feeding habits, the carp catla (Catla catla) in the ratio 60%-40%, resulted in very high fish production, superior to monoculture of either species.(as reported by research)
u can start integrated fish farming which involves farming of fish along with livestock and agricultural crops. This type of farming offers great efficiency in resource utilization, as waste or byproduct from one system is effectively recycled. It also enables effective utilization of available farming space for maximizing production.
