FISHERIES

Fish Production of Belagavi District: Inland fish production in Belagavi is majorly carp based. Carp seeds produced and distributed to farmers from Hidkal and Navilutheertha seed production and rearing centers by Department of Fisheries, Belagavi. Diversity of wild caught landings (other than carps) also contribute partially (20%) to the total production. Fish production of the distirct in last 11 years is illustrated in the chart below.

Fish seed production and stocking pattern
Department of Fisheries, Belagavi supplies fish seeds from three farms. Details of the capacity of the each fish seed farms are given in the table below. It is estimated that the district requirement of fish seeds per year is about 40lakhs of advanced fingerlings (82 lakh fry).

 Inland Fishery Resources of Belagavi District
Belagavi is one of the resource abundant districts in Karnataka where ample opportunity exists for fisheries enterprise. Following table illustrates the inland resources of the district with water spread area.

A total of 16 Fisheries Co-operative Societies are functional in the district with 1884 active members involved. Majority of the members involved in fishing in reservoirs, rivers,  major and minor tanks of the district. The district has 4161 fishermen (3782 male and 379 female) population altogether.
Productivity of Reservoirs: Central Inland Fisheries Research Institute (CIFRI) estimated productivity of Malaprabha reservoir is 6 Kg/yr/ha and the productivity of Ghataprabha reservoir is 4Kg/yr/ha. This productivity is considered as medium and low respectively.Accurate productivity of Markandeya and Rakkasakoppa remained unknown. Major landings (fish fauna) of the reservoirs of Belagavi and their local name is given in below table.

Fisheries in Tanks
Tanks are the major contributor to total district fish production and estimated to contribute more than 80% of total fish production of the district. Talukwise details of the tanks are given in the table below.

The average productivity of larger tanks is estimated to 700-800Kg/ha/yr. Apart from stocking fish seeds, other aquaculture management practices such as feeding and manuring are not practiced. Tanks previously considered as Fish Farmers Development Authority Tanks (w.s.a less than 10ha) have shown the productivity of 2 Tonnes/ha/year. This figure indicates that additional management practices have been taken to increase the production.  
Other Potential Areas for Fish Production:
ICAR-BIRDS Krishi Vigyan Kendra is emphasizing fisheries in non conventional waterbodies as their potential is immense. Alkaline, saline and waterlogged areas are the real treasure for inland aquaculture. Andra Pradesh and Raichur, Bellari and Koppal districts of Karnataka has proved these type of lands are best suited for aquaculture when there is limited possibilities with agri and horticulture crops. Following table gives the details of extent problematic lands in Ghataprabha and Malaprabha CADA jurisdiction. The details of the technologies for fish farming in problematic areas are covered in the later part of this document.  
Water storage-cum-irrigation tanks:
Adjacent to Krishna river belt, more than 80 number of storage ponds were built and each are having water spread area of 1 acre and more which are potential fish farming sites. In addition, under Krishi Bhagya Yojane of Karntaka State Department of Agriculture, more than 15,000 numbers of smaller water bodies area ranging from 200m2 to 500m2built across the district. Department of Horticulture under National Horticulture Mission has also helped farmers to build farm ponds. In addition, many farmers are having pipeline collection from rivers and canals also have built farm ponds of area ranging from 1000m2 to 3000m2. Although storage tanks or farm ponds are considered as relatively smaller structure and regular inflow and outflow of water hinders the planktonic production, these water bodies cannot be ignored for fisheries activity. These are individually owned waterbodies by farmers and hence, effective utilization is possible for either fish seed rearing or grow out production with slight and need based technological modification. The customized technological modification is discussed in later part of this document in detail.
