The treatment on this study using termites feed and pelet by different percentages. Aquarium A treatment = 20% termites; 80% pelets, aquarium B = 40% termites; pelets 60% and aquariums C = termites 60%; pelet 40%. The results showed that the percentage of pellet feed on termites and provide a better relative growth in treatment A 0.42 grams, C 0.26 grams and 0.10 grams B. FCR best value is obtained by treatment A 2.04 followed by C 3.3 and B 7.9. Similarly, the value of feed efficiency best values obtained by the treatment of A 51.6%, followed by C 29.58% and B 11.02%. Values lowest feed costs obtained by the treatment A Rp. 4112, -, followed by C Rp. 4496, - and B Rp. 5008, -.

Selain kajian ekologi, kajian sosial ekonomi tentang peran masyarakat dalam memanfaatkan potensi sumberdaya pesisir juga perlu dilakukan untuk mendesain model pengelolaan pesisir yang tepat. Tujuan dari penelitian ini adalah untuk mengetahui bentuk pemanfaatan sumberdaya pesisir oleh masyarakat di Distrik Manokwari Selatan dan untuk mengetahui persepsi dan partisipasi masyarakat tentang pelestarian ekosistem pesisir. Penelitian berlangsung pada April hingga Juli 2013, bertempat di Rendani, Sowi IV, dan Arfai, Distrik Manokwari Selatan. Pengumpulan data dilakukan dengan observasi dan wawancara. Pengolahan data persepsi secara tabulasi yang dinyatakan dalam persen (%) dan disajikan dalam bentuk diagram, selanjutnya dilakukan analisa interpretasi dengan menggunakan referensi terkait. Hasil penelitian memberi informasi bahwa masyarakat telah memanfaatkan mangrove dan karang untuk berbagai peruntukan, sedangkan lamun belum dimanfaatkan. Terdapat bentuk pemanfaatan yang bersifat merusak seperti penebangan mangrove dan penambangan karang. Responden menilai bahwa kondisi lingkungan pesisir telah rusak, terutama ekosistem mangrove (97%) dan terumbu karang (83%). Permasalahan yang paling dominan adalah berkurangnya sumberdaya ikan (98%) dan terkontaminasinya laut oleh sampah (97%). Responden juga menilai bahwa perlu ada upaya pelestarian sumberdaya alam pesisir dan lautan seperti penanaman mangrove (47%) dan karang (32%). Partisipasi masyarakat dalam pelestarian ekosistem pesisir tergolong rendah, baru sampai pada tahap restorasi, dan termasuk partisipasi yang dimobilisasi.
