MASS PRODUCTION OF TUBIFICID WORMS (Tubifex sp.) FROM UTILIZATION OF CATFISH GROW-OUT WASTEWATER  

Catfish (Clarias sp.) culture was carried out intensified with a higher stocking density, which will result in increased production of fish consumption and improve waste of grow-out activities. Waste water catfish grow-out is rich in nutrients that can be used for media cultivation natural feed, as well as feed tilapia fish or other.

Hatchery for freshwater fish (fish consumption or ornamental) are still heavily dependent on the natural food for early development,  such as Rotifers, Daphnia sp., tubicid worms (Tubifex sp.), etc. The availability of natural food, especially during the tubicids worm is supplied from collecting in nature (river, or channel of household), whose production is not stable in the wet season production is greatly reduced while for Daphnia and rotifers can be cultivated already with the use of organic fertilizers such as chicken manure  and others. So that the necessary efforts to meet the needs of the tubicid worms that can be met from the utilization of waste water engineering innovation catfish grow-out for the mass production of tubicid worms. Production of tubicid worms by utilizing the waste water flow of 24 catfish grow-out tank each size of 2 x 6 x 1.5 m³ tubicid worms can be obtained on average 22 liter per month or  330,000 IDR. liter. As an additional income for farmers catfish and catfish enlargement. Condition tubicid worms generated more clean than from the catch of public rivers. This technology is very easy to implement and is a solution to meet the needs of natural food for the larvae of freshwater fish as well as additional income from catfish farmers and cope with the smell of sewage feed catfish grow-out.
