ABSTRACT Mangrove crab (Scylla serrata) and swimming crab (Portunus pelagicus) are economically important marine commodities produced from the coastal waters of Sangihe Islands Regency. But those marine commodity products are usually only caught accidentally with a bottom gill net. There has been a special trap fishing gear for that resources, but not known well by local fishermen. Addition of squid oil extraction baits could increase the fishing power of mangrove crab and swimming crab traps. This research aims to study the effect of squid oil extract on traps bait to catch mangrove crab and swimming crab; and identify the types of biota captured. This research was done in coastal waters of Malise village, Tabukan Tengah District of Sangihe Islands Regency for 2 weeks September 2015; based on experimental method. Six unit traps were operated ten trips where three units of them used scad mackerel bait that injected with squid oil extract, and tree other units just used scad mackerel bait without extract; and the capture data were analyzed using t test. The catch was 142 individuals (135 mangrove crabs and 7 swimming crab); where 86 crabs was caught by scad mackerel bait with squid oil extract, and 56 crabs caught with bait without squid oil extract. The analysis showed that the use of squid oil extracts on trap baits increased the catch.

Abstrak : Penangkapan rajungan di perairan Pantai Purirano umumnya dilakukan oleh usaha perikanan rajungan skala kecil, yang menggunakan jaring insang (gillnet). Gillnet merupakan alat tangkap pasif yang pengoperasiannya tidak merusak sumberdaya hayati perairan. Walaupun demikian, gillnet merupakan alat tangkap yang tingkat selektivitasnya rendah, sehingga dikhawatirkan hasil tangkapan sampingan (bycatch) lebih banyak daripada hasil tangkapan utama (target species). Penelitian ini bertujuan untuk mengetahui proporsi hasil tangkapan rajungan (portunus pelagicus) sebagai target utama dan komposisi bycatch alat tangkap gillnet di perairan Pantai Purirano.Sampel rajungan ditangkap menggunakan jaring insang (gillnet) dengan ukuran mata jaring 4 inci & lebar jaring 80 cm. Hasil tangkapan selama penelitian diperoleh 29 jenis dari 25 famili. Hasil tangkapan yang diutamakan adalah rajungan dari famili Portunidae, tetapi terdapat juga jenis-jenis lain yang juga tertangkap (bycatch), yang sebagian dimanfaatkan (useable) dan sebagian lain dibuang ke laut (discarded). Jumlah total hasil tangkapan rajungan jantan selama penelitian adalah 58 ekor (54%) dan betina sebanyak 50 ekor (46%). Indeks dominansi hasil tangkapan tergolong rendah yaitu berkisar 0,21 – 0,27. Hal ini mengindikasikan bahwa selektivitas alat tangkap jaring insang tergolong rendah.Kata Kunci : Rajungan (Portunus pelagicus), Bycatch, Gillnet, PuriranoAbstrack : Catching crabs in Purirano Beach is generally carried out by small-scale crab fishing businesses, which use gillnet. Gillnet is a passive fishing gear whose operation does not damage aquatic biological resources. However, gillnet is a fishing tool with a low selectivity level, so it is feared that bycatch by-catch is more than the main catch (target species). This study aims to determine the proportion of crab catches (portunus pelagicus) as the main target and the composition of gillnet fishing gear bycatch in Purirano Beach waters. Swimming crab samples were captured using gill nets with mesh sizes of 4 inches & net width of 80 cm. The catch during the study obtained 29 species from 25 families. The preferred catch is crabs from the family Portunidae, but there are also other species that are also caught (bycatch), some are used (useable) and some others are thrown into the sea (discarded). The total number of male crab catches during the study was 58 individuals (54%) and 50 females (46%). The catch index dominance is relatively low, in the range of 0.21 - 0.27. This indicates that the selectivity of gill nets is relatively low.Keywords : Rajungan (Portunus pelagicus), Bycatch, Gillnet, Purirano
