Fish Farming & Aquaculture Methods





Cage System


  • This is an off-shore method of fish cultivation. The fish you are looking to grow are kept in cages in ponds, lakes, or even the sea. The fish are fed manually and attempts are made to ensure that the fish have the most natural sort of environment to grow in. The biggest concern with cage fish farming systems is that the fish may escape into the ocean. If the variety of fish being grown is not local to the area it could cause a disruption in the natural balance

Pond System


  • Ditches or ponds are built next to fields that can house the fish. The pond fish farming method is very popular in rural areas where access to fish farming equipment might not be readily available. The Irrigation ditch built for farming is meant to be self-sustainable and able to hold not just the fish but enough vegetation and algae to help feed the fish. The fish waste is also used to fertilize the fields nearby leading to a circular co-dependant system. KisaanMitrr, best fish farming.

Biofloc Tank System


  • Biofloc is the suspended growth in ponds/tanks which is the aggregates of living and dead particulate organic matter, phytoplankton, bacteria and grazers of the bacteria. The global population is expected to reach 9.6 billion by Yr. 2050 and as the demand for animal protein is increasing year by year it is a challenge to provide quality protein by safeguarding its natural resources for future generations.

RAS System


  • Recirculatory Aquaculture System (RAS) is a technology where water is recycled and reused after mechanical and biological filtration and removal of suspended matter and metabolites. This method is used for high- density culture of various species of fish, utilizing minimum land area and water.The technology is based on the use of mechanical and biological filters and the method can be used for any species grown in aquaculture. New water is added to the tanks only to make up for splash out, evaporation and that used to flush out waste materials. The reconditioned water circulates through the system and not more than 10% of the total water volume of the system is replaced daily.

Cold Water Fishery


  • To utilize the cold water resource, number of fast growing and economically viable species have been introduced, which include species of Carp and Trout. The Rainbow Trout (Oncorynchus mykiss) is a temperate region (cold water) carnivorous fish species which needs crystal clear and highly oxygenated water, thus well suited for water systems of Himalayan states. Rainbow Trout farming has great potential in India since Trout is one of the high value species and having high demand in both domestic and international market. Trout farming is common in the states of J&K, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh and Ladakh due to the suitable temperature (5° - 18°C).

Mariculture


  • Mariculture is a specialized branch of aquaculture involving the cultivation of marine organisms for food and other products in the open ocean, or in tanks, ponds or raceways which are filled with seawater. An example is the farming of marine fish, including finfish and shellfish like cobia, pompano, sea bass, lobster, oysters and seaweed in salt water resources. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery (e.g. cultured pearls), and cosmetics. Fish raised through mariculture practices are perceived to be of higher quality than fish raised in ponds or tanks, and offer more diverse choice of species.
