Care and Shelter for Rohu Fish

When it comes to caring for Rohu fish, it’s essential to create a suitable environment for them to thrive. Rohu fish farms are typically built on land that is not suitable for agriculture. One of the key factors to consider when setting up a fish farm is ensuring that the land can hold water. Additionally, it is crucial to avoid using sandy or loamy soil for pond construction as it may cause water leakage.

To maximize the productivity of Rohu fish farms, three main types of fish ponds are commonly used. The first type is production ponds, which are designed for breeding and growing fish to market size. Rearing ponds are used to rear fingerlings until they reach a suitable size for stocking in production ponds. Lastly, nursery ponds are utilized to raise young fish from larvae until they reach the fingerling stage.

Fertilizer management plays a significant role in the aquaculture of Rohu fish. Organic fertilizers, derived from agricultural and animal waste, provide essential nutrients for the growth of phytoplankton, which serves as the main source of food for adult Rohu fish. Inorganic fertilizers, consisting of mineral nutrients produced in industries, can also be used to supplement the nutritional requirements of the fish.

Key Points:

  • Choose land that can hold water for setting up Rohu fish farms.
  • Avoid using sandy or loamy soil for pond construction to prevent water leakage.
