Mutualism Symbiosis of Silkworm and Catfish Aquacultureto Provide Fish-based Protein for Local Community in Salak Malang Hamlet, Banjarharjo Village, Kalibawang District, Kulon Progo Regency
The application of appropriate technology on the concatenate of silkworm (Tubifex tubifex) and catfish (Clarias sp.) aquaculture was carried out in Salak Malang and Salam Hamlets, Banjarharjo Village, Kalibawang District, Kulon Progo Regency, Special Region of Yogyakarta, Indonesia. The main concept of this appropriate technology is to establish a mutualism symbiosis by creating water recirculation between silkworms and catfish ponds. The results show that an increase in the water flow frequency from catfish ponds to silkworm culture areas has the potential to provide higher silkworm production. The integration of silkworm and catfish aquaculture may also reduce catfish's Feed Conversion Ratio (FCR) to around 0.7-0.9. This alleviation in FCR value indicates the feed efficiency that reduces feed costs, making catfish farming more effective and efficient. By applying this appropriate technology, the number of silkworms required for catfish seed in Banjarharjo Village would still be fulfilled, and simultaneously the availability of fish-based protein from catfish available for the silkworm farmer and the local community.
