SALVAGE OYSTER MUSHROOM Pleuratus ostreatus AS CULTURE MEDIA OF WORM Lubricus rubellus FOR FISH FEED

Diversification of the local feed ingredients to substitute some or all imported feed ingredients should be studied and developed technically and economically sustainable. Worm Rubellus Lumbricus is one of alternative feed ingredients as a source of protein that has the potential of both productivity and quality, and has the potential to be developed. Worm contains 64-76% protein that is easily digested and broken down into amino acids which are beneficial to the body and various enzymes.

The purpose of the activities that take advantage of the waste of oyster mushroom logs as a medium for the cultivation of worm Lumbricus rubellus. Furthermore, the worm Lumbricus rubellus can be used as feed either directly or as a constituent ingredient of fish feed manufacture. The activities carried out in BPBAT Mandiangin South Kalimantan Province. Materials and equipment used are worm Lumbricus rubellus seeds, oyster mushroom log salvage, organic waste as feed, scales and pond culture of size 1.25 x 1.5 m² as many as 10 pieces.

Biomass growth out and the increase in the number of individual worm Lumbricus rubellus since stocked measured after one month of maintenance. The results showed an increase in the biomass starting from the second month until the end of the activity. The production of biomass is harvested after four months of maintenance, from the initial stocking of seeds as much as 1 kg/ m² produces to become 4 kg/m² or increased up to four fold. The next harvest cypress months with a mean weight of the harvest 1 kg/ m².

Of the activities carried out can be concluded utilization of oyster mushroom log salvage as worm Lumbricus rubellus culture media and given additional feed in the form of organic waste can increase production. In addition to loose mushroom logs also contain nutrients and organic matter that can be utilized optimally worm Lumbricus rubellus.
