FISH RESOURCES CONSERVATION BY INDIGENOUS FISH SPECIES CULTURE IN KALIMANTAN

Preserving the fish resources is one of the components to guarantee the existence, availability, and sustainability of certain fish species specifically to the endangered or nearly extinct fish species to ensure the sustainability.   The species conservation can be conducted by rearing and developing species.  Some indegenous species of Kalimantan is now lower in population caused by massive and uncontrolled capture fisheries.  Aquaculture could be one of the solution to maintain biodiversity by domestication in form of applied research on development.  Eksploration, collection, documentation, characterization, breeding technology both natural and artificial, grow out, and reproduction are some aspects to  be consideration.    

The indigenous fish species develop by Mandiangin Freshwater Aquaculture Development Center (MFADC) based on the availability in natural habitat and consumer demand such as climbing perch (Anabas testudineus, 1792), snakehead (Channa striata Bloch, 1793), hovens carp (Leptobarbus hoevenii), kelabau (Osteochilus melanopleurus), knife fish (Chitala lopis) dan arwana (Scleropages formosis). Some of those fish species are well domesticated.  In addition the climbing perch and snakehead have acknowledge legally by Ministry of Marine Affairs and Fisheries.  Nowadays, MFADC has produced the forth generation of climbing perch, third generation of snakehead brood stock, and the fingerlings spread throughout fish farmers.  There is also development of Kelabau fingerling and brood stock which still on going.

Dissemination on indigenous species culture after domestication also conducted by MFADC to fish farmers by means of technical assistance, training and demonstration pond culture.    Fish rearing technic by using controllend tank (cage and pond culture) for eight months  results the initial weight 7,18±3,14 gram/fish of snakehead and 190,52±6,61 gram/fish in final weight by survival rate 80,9±2,21 %.  For the climbing perch result the initial weight  1,63±0,093 gram/fish and 77,04±9,8925 gram/figh final weight by survival rate  87,6±7,21 %. In addition to domestication and dissemination, MFADC also conducting restocking on climbing perch and hovens carp in open water especially around South, Central, and East  Kalimantan.   Therefore, the indigenous species culture and the dissemination can directly useful as species diversification, supporting food security, livelihood among the fish farmers and as a matter of natural conservation.
