The result of this activity is the availability of three tarpaulin catfish ponds measuring 3 ´ 2 m2 each which can be used by the reformatory students as a medium for life skills training. The time for putting baby fish into the three ponds was scheduled in different times so that the harvest time would also be different such that market oversupply can be avoided. During the farming period, the reformatory students were very enthusiastic in feeding and monitoring the condition of the pond water and the growth of the catfish, so that catfish farming could run as expected. The first harvest was partly consumed and the other was sold to the local market.
