Epinephelus Fuscoguttatus

Penelitian ini bertujuan untuk menentukan dosis pemberian enzim papain dalam meningkatkan efisiensi pakan dan pertumbuhan ikan kerapu cantang Epinephelus fuscoguttatus x Epinephelus lanceolatus. Penelitian ini dilakukan pada bulan Oktober 2019 selama 42 hari di Hatchery Skala Rumah Tangga Koperasi Marin Agri Sejahtera, Kota Tanjungpinang Kepulaun Riau. Metode yang digunakan ialah eksperimental dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan dimana perlakuan K (tanpa pemberian enzim papain), perlakuan A (dosis enzim papain 2,75%), perlakuan B (dosis enzim papain 3,75%), perlakuan C (enzim papain 4,75%). Hasil penelitian melalui analisis statistik, pemberian dosis enzim papain mampu memberikan pengaruh yang signifikan (P<0.05). Dosis yang terbaik didapatkan pada perlakuan A dengan pemberian dosis enzim papain sebanyak 2,75% dimana hasil yang didapatkan pada parameter efisiensi pakan (69.66±1.32%) dan pertumbuhan bobot mutlak sebesar (18.47±0.03 g).

Fish Trade

The harvesting of groupers (Serranidae) in Indonesia for the live reef food fish trade (LRFFT) has been ongoing since the late 1980s. Eight sites in Komodo National Park that included two fish spawning aggregation (FSA) sites were monitored for groupers and humphead wrasse,Cheilinus undulatus, from 1998 to 2003 and from 2005 to 2008 to examine temporal changes in abundance and assess the effectiveness of conservation and management efforts. Monitoring identified FSA sites for squaretail coralgrouper,Plectropomus areolatus, and brown-marbled grouper,Epinephelus fuscoguttatus. Both species formed aggregations before and during full moon from September to December, prior to lapses in monitoring (2003–2005) and in enforcement (2004-2005). Following these lapses, data reveal substantial declines inP. areolatusabundance and the apparent extirpation of one aggregation at one site. Other non-aggregating species targeted by the LRFFT showed similar declines at three of eight monitored sites. This paper highlights the impact of FSA fishing and the need for a seamless monitoring and enforcement protocol in areas where aggregation fishing pressure is high. Within Komodo National Park, local fishers, particularly those operating on behalf of the LRFFT, pose a serious threat to population persistence of species targeted by this trade.
