PERFORMANCE OF GILLNET-MESH SIZE SELECTIVITY FOR THREE FLYINGFISH SPECIES IN AMBON WATERS, MOLUCCAS PROVINCE Hutubessy, Barbara Grace; Syahilatua, Augy
Marine Research in Indonesia Vol 35, No 2 (2010)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

The gillnets performance for capturing flying fish was obtained from the selectivity parameters of each mesh size. Gillnet selectivity parameters for flying fish were estimated using multi-panel drift gillnets with four different mesh sizes in southern Ambon Island. The black-spot flying fish Cheilopogon suttoni reached peak selectivity at 20.34 cm for mesh size of 1.25", 24.37 cm (1.5") and 28.47 cm (1.75"). Peak selectivity occurred at 22.16 cm for the 1,25" mesh size in the yellow-spot flying fish Cheilopogon abei, with the maximum size selectivity at 31.61cm for the 1.75" mesh. The optimum size for the black-plain flying fish Hirundichthys oxycephalus was 18.67 cm for the 1.25" mesh size, and 22.37 cm for 1.50" mesh size. Selectivity was highest at 26.12 cm for the 1.75" mesh size. Gillnet used in this study was constructed specifically for targeting flying fish suggesting that information on mesh selectivity examined here should has direct applicability to local flying fish fishery.

Fisheries management or conservation requires information on length-weight relationship (LWR) for the fishing regulation and biomass estimation. This study aims to assess LWR estimation using two methods, regular and Bayesian hierarchical approached for big-eye Scad (Selar crumenophthalmus). Samples of big eye Scad were collected at several fish landings around Ambon Island from March to August 2020. Length-weight relationship measurement to obtain the parameters of W = a*Lb was tested using generalized linear model and t-test. The parameter b for monthly sampling was not significantly different (F = 0.77, df = 70, P = 0.89) and showed isometric growth b=3 (t = -1.13, df = 4, P = 0.32). Regular measurement resulted parameter log10(a) = -1.99 (±SD = 1.06) dan b = 3.06 (±SD = 0.084). Bayesian method produced parameter log10(a) = -2.07 (±SD = 0.2365) dan parameter b = 3.21 (±SD = 0.1497). Weight measurement from HB approach was significantly higher than the regular method (t = 1.65; df = 405; P <0.0001), and might produce over-estimated of weight from length data. Discrepancy of these methods was overcome by combining all information of LWR to obtain the best estimation on LWR parameters. Abstrak Pengelolaan perikanan atau konservasi memerlukan informasi tentang bobot ikan untuk estimasi biomassa dan regulasi penangkapan. Tujuan penelitian ini adalah untuk membandingkan hubungan panjang-bobot hasil pendekatan hirarki bayesian dengan pengukuran regresi langsung ikan selar bentong, Selar crumenophthalmus. Ikan selar bentong dikoleksi dari lima tempat pendaratan ikan di Pulau Ambon dari bulan Maret hingga Agustus 2020. Pengukuran panjang total dan bobot ikan selar bentong bertujuan untuk memperoleh hubungan panjang-bobot dengan formulasi W = a*Lb. Uji general linear model dipakai untuk menguji parameter b (kemiringan) pada bulan pengamatan yang berbeda. Uji-t satu sampel dipakai untuk menguji pertumbuhan isometrik (b=3). Hasil penghitungan hubungan panjang-bobot berdasarkan pengukuran langsung dibandingkan dengan hasil estimasi dengan pendekatan bayesian dan diuji dengan uji-t. Nilai parameter b dari pengamatan langsung tidak berbeda untuk bulan pengamatan (F = 0,77, df = 70, P = 0,89) dan ikan selar memiliki pola pertumbuhan isometrik, b=3 (t = -1,13, df = 4, P = 0,32). Pengukuran regresi langsung memperoleh parameter log10(a) = -1,99 (±sb = 1,06) dan b = 3,06 (±sb = 0,084). Metode Bayesian menghasilkan parameter log10(a) = -2,07 (±sb = 0,2365) dan parameter b = 3,21 (±sb = 0,1497). Estimasi bobot dengan pendekatan bayesian terlalu tinggi (t = 1,65; df = 405; P < 0,0001), memungkinkan timbulnya bias pada pendugaan biomassa. Hasil ini berarti metode bayesian adalah over estimasi, sehingga perlu banyak data dan info yang digabung untuk menekan bias dalam mengestimasi hubungan panjang-bobot dan biomassa.

Nelayan mengetahui sumberdaya laut secara rinci, juga lingkungan mereka dan aktifitas penangkapan yang mereka lalukan, dan pengetahuan ini jarang dikoleksi secara sistimatik. Penelitian ini dilakukan untuk menguji persepsi nelayan terhadap perubahan hasil tangkapan dan penyebabnya. Kami mewawancarai nelayan pantai Haive Besar dengan menggunakan kuisioner yang sifatnya semi terstruktur. Informasi pribadi nelayan seperti umur dan pengalaman menangkap ikan, aktifitas penangkapan seperti alat yang digunakan dan daerah penangkapan, serta pengetahuan mereka tentang perubahan ekosistem menjadi topik pertanyaan di dalam kuisioner. Nelayan dengan usia karir menengah (21-35 tahun) lebih banyak dibandingkan nelayan usia karir muda dan karir tua. Nelayan mendeteksi perubahan pada ekosistem daerah penangkapan mereka seperti banyaknya sampah, limbah minyak, rusak dan berkurangnya habitat karang dan lamun serta kekeruhan. Dampak yang nelayan rasakan adalah hasil tangkapan yang semakin berkurang bahkan tidak ada lagi. Persepsi nelayan terhadap perubahan ekosistem dan hasil tangkapan mereka menjadi dasar bagi penelitian selanjutnya seperti fisheries assessment. FISHERS’ PROFILE AND PERCEPTION ON THE SHIFTING OF CATCH ON THE COAST OF AMBON BAY. Fishers have detailed knowledge of their resources, their environment, and their fishing practices that is rarely systematically collected. This study was undertaken to examine perceptions of fishers on the shifting of catch and the occasion of the changing. We conducted an interview with coastal Hative Besar fishers using a semi-structured questioner. Fishers’ profiles such as age and years at fishery, gears and fishing grounds was one part of the questions. Other part was fishers’ ecological knowledge focused on environmental condition and shifting catch. More fishers with middle career (21-35 year in fishery) than young and old careers were interviewed. Environmental changes included waste in the water, oil, corals and seagrasses degradation, and turbidity affected the catch of fishers. Fish became difficult to be found. We learn from this study that fishers’ perception is an important tool for further fisheries assessment study.

Publisher : Universitas Bengkulu

Jaring insang digolongkan sebagai alat tangkap yang ramah lingkungan mengingat ukuran ikan yang tertangkap dipengaruhi oleh ukuran mata jaring yang digunakan. Penelitian yang dilakukan selama 2013-2014 di perairan Kotania, Kabupaten Seram Bagian Barat bertujuan untuk menghitung kelimpahan ikan pada spektrum ukuran (abundance size-spectrum) berdasarkan habitat ikan pada waktu yang berbeda. Data dikumpulkan melalui logbook yang diisi oleh nelayan Dusun Pulau Osi dan Dusun Wael dengan daerah penangkapan di Teluk Kotania. Distribusi panjang ikan hasil tangkapan setiap mata jaring menunjukkan kisaran panjang yang tidak beraturan yang bisa menimbulkan selektivitas yang tidak konsisten. Ketidakpastian selektivitas jaring insang yang dioperasikan pada perairan dangkal disebabkan oleh perubahan pilihan habitat sebagai daerah penangkapan nelayan. Spektrum panjang menunjukkan distribusi panjang yang unimodal dengan jumlah ikan jenis ikan berukuran kecil tinggi dan menurun secara eksponensial untuk jenis ikan berukuran besar. Mengingat ikan besar mempunyai peranan penting dalam komunitas, dan kurang rentan terhadap jaring insang, kami menyimpulkan bahwa jaring insang adalah alat yang ramah lingkungan.EVALUATION OF GILLNET SELECTIVITY IN KOTANIA BAY, WEST PART OF SERAM. Gillnets are categorized as environmentally friendly fishing gear convinced by its selectivity. Study conducted at Kotania Bay, West Seram Regency, for two years (2012-2013) aimed to count the abundance size-spectrum on habitat for evaluating the catch of gillnets. Length distribution of catch for each mesh size showed irregular ranges, which may lead to selectivity uncertainties. Data was collected from logbooks filled by fishers from Osi Island and Wael. Uncertainty of gillnets selectivity which were operated in shallow waters was influenced by the fishers’ habitat preference that was distinct temporally. The size-spectra of exhibited unimodal length distribution with high catch of small-bodied species and lowered exponentially towards large-bodied species. As large- bodied species play important role in the community and they are less vulnerable to gillnets, we concluded that the practices of gillnet at Kotania Bay are environmentally friendly gear.

Various fishing gears that are operated in the coral reef waters of Western Seram Regency have their own selectivity, capture various species of fish, and have an impact on the damage to coral reef ecosystems. This study aims to determine the leading reef fishing gears in Western Seram District. The survey method is through observations and interviews with fishermen who conduct fishing activities of coral species. Respondents are determined by propulsive sampling, the selection of superior fishing gear is done by the scoring method. The results showed that the fishing gear classified into the line fishing gear was superior to other fishing gear, where the bottom trolling were superior. The less favored coral fishing equipment especially from the biological aspect needs attention to improve the method and design of the fishing gear.

The aim of this research was to know the effectiveness of the trap which was modified and redesigned from its original. The research was conducted in the water of Baa, Rotendao district, East Nusa Tenggara Province. The trap was operated for 3 months started from August to November 2004 by using three types of baits. Fishes were collected from the trap every 2-3 days immersion by pulling up the trap on board. There were 69 individuals fishes in one trap representing 11 families and 15 species. Most fish species were highly economic values and was dominated by snappers (Lutjanidae) and groupers (Serranidae). The fish size were ranging from 17 to 29 cm of tolat lenght (TL). There was no significant difference between bait used on the catch (p>0.05) suggesting that bait may not be required anymore on this specific reef fishing methods. It is realized that further studies may be required, however in the mean time, this gear may provide an alternative method for small scale reef fishing.

Larval occurrence in Ambon Bay is related to the larval settlement and indirectly affects the population of pelagic species which have nursery ground in Ambon Bay. The objective of this study is to analyze the factors that influence larval fish occurrence in Ambon Bay based on the length distribution. A lift net assisted by 6 LED lights was operated during the dark to catch larval fish and data was collected from 2016-2018 at Hative Besar, Ambon City. Length frequency with a 5 mm interval was set following the sampling dates. Two variables: length frequency and the number of new individuals (<20mm) together with information on tides and moon phase obtained from the website were collected for further analysis. The larval occurrence was associated with 4 moon phases (dark, first quarter, full and third quarter) and with 2 types of tides: semi-diurnal and mixed semi-diurnal. The normality test (Kolmogorov–Smirnov test) showed normal distribution on length data and the ANOVA showed no significant difference in larval occurrence among the moon phases (F=1.223, P=0.318) but between semi-diurnal and mixed semi-diurnal, and larval recruitment was significantly different (F=3.07; P=0.003), small size larvae were abundance during semi-diurnal tides while large larvae during mixed semi-diurnal tides. It is concluded that small pelagic larval occurred throughout the year and the new cohort occurred by the influence of the tidal current to Ambon bay. Our findings highlight the biological impacts of lift net siru-siru as priorities for the management of fisheries in Ambon bay. Abstrak Pola kehadiran larva ikan di Teluk Ambon berkaitan erat dengan proses menetap dan secara tidak langsung berkaitan juga dengan dinamika populasi ikan pelagis yang memilih daerah pembesaran di dalam Teluk Ambon. Penelitian ini bertujuan untuk menganalisis faktor lingkungan yang memengaruhi kehadiran pra-menetap larva ikan pelagis kecilberdasarkan frekuensi panjang. Larva ikan ditangkap dengan menggunakan siru-siru dengan bantuan lampu di malam hari. Sampling dilaksanakan dari tahun 2016 hingga 2018 di Negeri Hative Besar, Ambon. Frekuensi panjang total larva ditabulasi dalam bentuk histogram dengan kisaran 5 mm untuk setiap tanggal sampling. Dua variabel: panjang dan jumlah individu baru (≤ 20mm) bersama dengan hari bulan dan pasang surut digunakan untuk analisis selanjutnya. Kehadiran larva dihubungkan dengan hari bulan (4 fase: bulan baru, kwartir pertama, purnama dan kwartir terakhir) dan tipe pasang surut (harian ganda dan tipe campuran). Uji normalitas Kolmogorov–Smirnov test menunjukkan sebaran data panjang normal (P=0.20). Selanjutnya hasil ANOVA menunjukkan kehadiran pra-menetap larva di Teluk Ambon tidak dipengaruhi hari bulan (F=1,223, P=0,318), tetapi dipengaruhi oleh pasang surut (F=3,07; P=0,003) ketika larva berukuran kecil lebih banyak tertangkap pada tipe harian ganda, sedangkan larva yang lebih besar pada tipe campuran. Kehadiran pra-menetap larva ikan pelagis kecil terjadi sepanjang tahun dan kehadiran individu baru di Teluk Ambon dipengaruhi oleh arus pasang surut. Hasil penelitian ini menyorot dampak biologis dari perikanan siru-siru sebagai prioritas pengelolaan perikanan di Teluk Ambon.

The highest protein resource is come from fish and fish meat contains Omega-3 Fatty Acid. Unfortunately, a publication of mercury contamination on fish has created public unsettling. Unlicensed gold mining in Buru Island and cinnabar rocks in Seram Island provides plenty of job opportunities, however the tailing causes mercury contamination into the ocean. It is therefore, teach people on how to consume fish without any further mercury contamination should be done. The aims of this public service is to provoke young age people or students to eat fish. It is also to teach students avoiding of being dangerous mercury contaminated. To achieve these aims, we discussed with Prof.Dr. Y. Malle, M.Si regarding mining contamination and continued with library searched. Then we taught this information to primary student of Citra Kasih Primary school in Ambon. Focus group discussion involving a professor who is expert on mercury contamination, and he concluded that the mining has contaminated surroundings sea water. Fish also can be contaminated through food chain. The important information should be taught to the people especially the young age or students. During the innovation and outing day of Citra Kasih Primary School, this important information was taught to the students. They were so enthusiasm to learn how to eat healthy fish without being contaminated. The Omega-3 fatty acid is important for their brain and their balance, so fish meals should put in their diet menu. It is concluded that fish provide protein and contain Omega-3. Eat healthy fish is by avoiding fish head and fish body cavity to avoid contamination.
