The purpose of this study is to determine the difference between the catches of the two boat lift net using collecting lights of different colors, this research was held in Polewali Mandar waters in September-November 2020 by following the operation of catching 2 boat lift units. The results showed that the boat using the green collecting light caught 1876.6 kg more fish than the boat using the red light 1534.4 kg, and boat that use green lights have more variety of fish species than boat that use red lights. The different types of fish in the two units of boat lift net are grouper, kerung-kerung, and shark.

Kajian pola kedatangan ikan dengan metode akustik ini dilakukan untuk mengetahui pola kedatangan ikan pada area penangkapan bagan perahu berdasarkan waktu dan kedalaman perairan. Studi dilakukan dengan metode experimental fishing dengan mengikuti operasi penangkapan pada satu unit bagan perahu di perairan Pantai Kota Parepare yang dilaksanakan pada Mei-Juni 2015. Hasil penelitian menunjukkan bahwa schooling ikan mendatangi sumber cahaya di area penangkapan bagan perahu sekitar 30-50 menit setelah penyalaan lampu pengumpul ikan. Kawanan ikan mendatangi sumber cahaya pada kedalaman 6-7 meter dengan pola soliter dan mendekat setelah 100-120 menit pada kisaran 2-3 meter dari permukaan laut dengan pola kedatangan ikan soliter dan bergerombol. Hasil ini dapat menj...

The present study aims to assess the effectiveness of the operation of the lift-net with hydroacoustic technology in an effort to increase the productivity of the fisherman of boat liftnet. The study was conducted on fishing activity of boat liftnet in the Makassar Strait from April to May 2015 by utilizing the tools of acoustic technology in the operation of the boat liftnet. The analysis method is based on the productivity of the boat liftnet. The results showed that the productivity of fishing gear which is operated by using the tools of fisheries acoustic were improved compared with the fishing effort without acoustic tools. This result is expected to be a reference to research on the use of acoustic technology in a variety of fishing gear and as reference to research ...

Penelitian ini bertujuan untuk menentukan produktivitas bagan perahu, menganalisis faktor teknis penangkapan yang berpengaruh terhadap produktivitas penangkapan, dan mendeskripsikan komposisi hasil tangkapan. Penelitian ini dilakukan di Desa Tobinta, Kecematan Karossa, Kabupaten Mamuju Tengah dari bulan Juni sampai Agustus 2018. Metode penelitian yang digunakan adalah studi kasus, dengan menggunakan analisis spearman untuk mengetahui faktor teknis yang berpengaruh. Hasil penelitian ini menunjukkan produktivitas bagan perahu yang mengalami tren peningkatan dari hauling I ke hauling II. Faktor teknis memiliki kedekatan hubungan atau cukup berpengaruh terhadap produktivitas bagan perahu, dan proporsi jenis ikan hasil tangkapan bagan perahu yang terbesar adalah tembang (Sardinella fimbriata) dan proporsi terendah adalah tongkol (Euthynnus affinis). Kata Kunci: Bagan perahu, Produktivitas, Teknis penangkapan.

Penelitian ini dilaksanakan di Desa Punagaya, Kec. Bangkala, Kab. Jeneponto pada bulan Juli sampai Agustus 2011. Metode penelitian yang digunakan adalah studi kasus pada dua unit penangkapan bagan tancap. Teknik pengambilan data yang dilakukan selama penelitian yaitu melakukan pengukuran secara langsung dilapangan. Perbandingan hasil tangkapan dilakukan dengan menggunakan uji perbandingan non parametrik Mann Whitney. Hasil penelitian menunjukkan produksi total bagan tancap yang dioperasikan dekat dari pantai sebesar 422,23 kg,sedangkan bagan tancap yang jauh dari pantai sebesar 732,92 kg. Terdapat 32 jenis ikan yang tertangkap dari bagan tancap dekat pantai, sedangkan bagan tancap yang jauh dari pantai terdapat 34 jenis ikan. Terdapat 10 jenis ikan yang dominan tertangkap, baik bagan tancap dekat pantai maupun yang jauh dari pantai. Tidak terdapat perbedaan produktivitas penangkapan yang signifikan antara bagan yang tancap yang dioperasikan dekat pantai dengan bagan tancap yang dioperasikan jauh dari pantai.

This research was conducted in the desa Punagaya, Kecamatan Bangkala, Kabupaten Jeneponto July to August 2011. The research method used was a case study on two fixed lift nets. Data retrieval techniques performed during the study, namely direct measurement field. Comparison of the catch is done using statistic nonparametric test of Mann Whitney. The results showed a total production of fixed lift net operated near the coast at 422.23 kg, while the fixed lift net away from the coach at 732.92 kg. There are 32 kind of fish caught fixed lift net near the coast, while the fixed lift net away from the coast there are 34 kinds of fish. There are 10 kinds of fish caught dominant, both fixed lift net near the coast beach and far from the coast. Mann Whitney test showed no significant differences in fishing productivity between fixed lift net operated near the coast and fixed lift net that operated away from the beach.

Monthly mean remotely sensed sea surface temperature and surface chlorophyll-a concentration during the southeast monsoon (April-August) were used for the year 2012. The best generalized additive model was selected to assess the effect of marine environment variables (sea surface temperature and chlorophyll-a concentration) on skipjack tuna abundance (catch per unit effort). Then, the appropriate linear model was constructed from the functional relationship of the generalized additive model for generating a robust predictive model. Model selection process for the generalized additive model was based on significance of model terms, decrease in residual deviance, and increase in cumulative variance explained, whereas the model selection for the linear model was based on decrease in residual deviance, reduction in Akaike's Information Criterion, increasing cumulative variance explained and significance of model terms. The best model was selected to predict skipjack tuna abundance and their spatial distribution patterns over entire study area. A simple linear model was used to verify the predicted values. Results indicated that the distribution pattern of potential fishing zones for skipjack during the southeast monsoon were well characterized by sea surface temperatures ranging from 28.5˚C to 30.5˚C and chlorophyll-a ranging from 0.10 to 0.20 mg•m −3. Predicted highest catch per unit efforts were significantly consistent with the fishing data (P < 0.01, R 2 = 0.8), suggesting that the oceanographic indicators may correspond well with the potential feeding ground for skipjack tuna. This good feeding opportunity for skipjack was driven the dynamics of upwelling operating within study area which are capable of creating a highly potential fishing zone during the southeast monsoon.
