Abstract

This paper describes the state of lobster resource which landed in Sorong, including species, fishing season, and the analysis of weight-length relationship. The measurements were carried out by using randomized sampling in three (3) lobster shelter in Sorong from September - November 2015. Total of 1.316 lobster were observed during this research. The data observed were species, carapace length (mm), weight (g) and gender. The aspects of fishing technique, season, marketing and lobster types were analyzed by using descriptive analysis, whereas the measurement data was analyzed by using linear allometrik model to see the weight-length relationship with the equation of W = a Lb . The result showed that there are six types of lobster which landed in Sorong namely are; Panulirus ornatus, P. versicolor, P. longipes, P homarus, P penicillatus, and Thenus orientalis. Fishing season was carried the whole year which consists of the peak season (June, November, December), middle season (March-July, September-October) and bad season (August, January, February). The whole lobster observed in this research have negative allometric growth pattern which indicates that the lobster are in growth stage.

Abstract

Size of the shrimp trawl will be proportional to the size of the propulsion power engine, that is more great tools to catch going to need a big powered ships for more economical. The goal of research is to productivity shrimp trawl and correlation of respondence between size of the fishing gear with power engine of the vessel. Methods of practice that is descriptive (describing systematically fact observation/ research about the operation the shrimp trawl and about shrimp trawl fishing gear) and quantitatively (using calculations of productivity and calculate the suitability of gear with power engine). Productivity KM. Soerya 86 is 66,4 tonnes while the corresponding data in the field catches 20,9% higher. Based on the calculations for KM. Soerya 86, size of the shrimp trawl appropriate supposed to 41,10 m while the field observations used mesh size of 18 m. Weight otter board according supposed 271,25 kg but field observation using only weight 220 kg. Otter board spacious appropriate but should 3,06 m2 observations in the field widely otter board using 2,31 m2.

Abstract

Penelitian bertujuan untuk mengetahui pengaruh perbedaan hanging ratio terhadap hasil tangkapan Gillnet. Penelitian dilakukan di Perairan Sorong, bulan Oktober 2013 - November 2013 menggunakan Gillnet dengan hanging ratio 0,30, 0,40, dan 0,50 masing-masing sebanyak 2 piece. Ketiga tipe gillnet dioperasikan secara bersama-sama. Hasil tangkapan selama penelitian dengan jumlah total pengambilan sampel 20 diperoleh 16 jenis spesies ikan yang didominasi oleh Belanak (Mugil cephalus) dengan jumlah dan total berat hasil tangkapannya adalah 166 ekor dan 125,60 kg, Daun Bamboo (Chorinemus spp) dengan jumlah dan total berat hasil tangkapannya adalah 146 ekor dan 131, 29 kg. Rataan jumlah ikan dan total berat hasil tangkapan per setting dari setiap jenis jaring insang memberikan indikasi adanya pengaruh nyata faktor hanging ratio. Rataan pada jumlah ikan Belanak (Mugil cephalus) per setting memperlihatkan kecenderungan menurun dengan meningkatnya hanging ratio. Sedangkan rataan jumlah ikan Bamboo (Chorinemus spp) terlihat maksimum untuk jaring dengan hanging ratio 0.40. Analisis sidik ragam menyimpulkan bahwa faktor tersebut signifikan pada taraf a = 0,05.
