Abstract

Fishermen in Wakal Village still water is pot to catch coral fish species. The pot is made from woven bamboo with small hexagonal-shaped cracks. The type of fish that are targeted by the catch usually after being caught in the traps suffer injuries to their bodies as they try to escape through small gaps that are hexagonal. The purpose of this study is to analyze the viability of fish after escaping to the cover net. The data were collected by experimental fishing using four units of pots that were cover net in 20 repetitions. The research was conducted from September to December 2018 in Wakal Village, and Central Maluku Regency. The total number of fish caught is only 2.83% of fish that escape into the net cover. Fish that escaped are divided into 7 species including Plectrypops lima, Pinjalo lewisi, Ephinephelus tauvina, Chaetodon kleini, Centropyge bicolor, Priolepis cincta, Paraluteres prionurus. The cause of fish death is not only assessed from the wounds on the body of the fish when escaping or the wounds resulting from contact with other fish but the stress from the fish itself. The environmental factors that greatly affect the survival of fish when escaping are temperature and salinity.  Nelayan di Perairan Desa Wakal menggunakan alat tangkap bubu untuk menangkap ikan karang. Bubu terbuat dari anyaman bambu dengan celah-celah berukuran kecil berbentuk hexagonal. Jenis ikan yang menjadi target tangkapan biasanya setelah tertangkap oleh bubu mengalami luka pada tubuhnya karena berupaya meloloskan diri melalui celah-celah kecil yang berbentuk hexagonal. Luka yang terdapat pada tubuh ikan dapat mengakibatkan kondisi yang buruk bagi kelangsungan hidup. Tujuan dari penelitian ini adalah Menganalisis kelangsungan hidup ikan setelah meloloskan diri ke cover net. Pengumpulan data dilakukan dengan uji coba penangkapan menggunakan 4 unit bubu buton yang dipasang cover net sebanyak 20 kali ulangan. Penelitian dilakukan pada bulan September-Desember 2018 di Desa Wakal, Kabupaten Maluku Tengah. Total jumlah keseluruhan ikan yang tertangkap hanya 2.83% ikan yang meloloskan diri masuk ke dalam cover net. Ikan yang lolos terbagi dalam 7 spesies diantaranya Plectrypops lima, Pinjalo lewisi, Ephinephelus tauvina, Chaetodon kleini, Centropyge bicolor, Priolepis cincta, Paraluteres prionurus. Penyebab kematian ikan bukan saja dinilai dari luka pada tubuh ikan saat meloloskan diri ataupun luka akibat dari kontak dengan ikan lainnya namun stress dari ikan itu sendiri. Adapun faktor-faktor lingkungan yang sangat berpengaruh terhadap kelangsungan hidup ikan saat meloloskan diri yaitu suhu dan salinitas.

Abstract

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.

Abstract

One of the fishery commodities with high economic value is tuna, where in the Maluku region in 2021, tuna production will be 35.56% (BPS, 2022). Tuna is caught using handlines which are classified as small-scale fisheries. The existence of tuna that changes over time causes fishermen to experience uncertainty in finding suitable fishing areas. Temperature is an important indicator in the distribution and abundance of tuna. This study aims to determine the composition of the hand line catch and to analyze the temperature distribution based on the area of ​​the hand line fishing operation in Central Maluku Regency. The research was conducted in the waters with the method used is a survey method by following fishing trips and using GPS satellite-based Spot Trace to track vessel movement activities during fishing operations. Descriptive data analysis was used to determine the composition of fisherman catches and used SeaWiFS Data Analysis System (SEADAS) 7.3.1 and Surfer 12 to analyze the distribution of water temperatures at fishing locations. The results showed that yellowfin tuna (Thunnus albacares) dominated the catch by 70.30%, bigeye tuna (Thunnus obesus) by 20.19% and skipjack tuna (Katsuwonus pelamis) by 0.52%. The frequency distribution of yellowfin tuna length ranges from 23-171 cmFL where during 2019 it was dominated by sizes <100 cmFL as much as 82.42%. The SST range in January is 290C-310C, optimal fishing is at 29.80C-30.40C, April is in the range of 30.20C-31.70C, optimal fishing is at 30.90C-31.30C, in May is in the range of 27.40C-31,40C the optimal catch is in the temperature range of 27.80C -30.80C, in June is 27.40C -280C the optimal catch is in the temperature range 27.60C-27.850C, in September 27.40C-29.50C the optimal catch is at a temperature range of 27, 80C -28.50C, and in December the range of 29.40C-31.50C is optimal for catching at a temperature range of 30.40C -31.20C

Abstract

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.

Abstract

Intensive and massive fishing exploitation of various reef fish resources occurs in coastal areas, including the Pteriocaesio tile (dark-banded fusilier). This study was conducted due to a lack of information, including size distribution, length of first captured (Lc), length at first mature (Lm), and the selectivity of the mesh size for Pteriocaesio tile caught in the Huamual Belakang waters. The data collection was conducted from September to December 2022. The experimental fishing method was conducted by operating one unit of encircling gillnet consisting of eight panels, each consisting of four mesh net units of 1.75 inch and 2.0 inch, installed randomly. Samples of fish caught for each actual fishing were measured for total length. The reproductive aspect used 10-15% of fish samples per trip. The fish were measured for total length and body weight, and dissected to determine the sex and gonad maturity level and weight. The catches with encircling gillnets were dominated by the Caesionidae family, consisting of Pteriocaesio tile at 74.73%, Pterocaesio chrysozona at 6.80%, and caesio caerulaurea at 6.41%. The size distribution of the total length of Pteriocaesio tile was 15.0 – 27.3 cm. The average length first caught in a  1.75-inch mesh was 21.4 cm, and 22.5 cm for the 2.0-inch mesh. The length at first mature was 18.6 cm for the female, and 20.6 cm for the male. The gillnet selectivity obtained 50% chance of being caught in the mesh size of 1.75 inches was 18.8 cm, and 21.9 cm in the mesh size of 2.0 inches. The status of the resource utilization of Pteriocaesio tile was in good condition (Lc > Lm). Nevertheless, the use of the 1.75-inch mesh size indicated recruitment overfishing   Eksploitasi penangkapan terjadi secara intensif dan masif di wilayah pesisir terhadap berbagai sumberdaya ikan karang termasuk ikan Pteriocaesio tile (dark-banded fusilier). Penelitian ini dilakukan karena masih minimnya informasi meliputi; distribusi ukuran, ukuran ikan pertama kali tertangkap, ukuran ikan pertama kali matang gonad, dan selektivitas ukuran mata jaring Pteriocaesio tile yang tertangkap di perairan Huamual Belakang. Pengumpulan data dilakukan pada bulan September sampai Desember 2022. Metode experimental fishing dilakukan dengan mengoperasikan satu unit jaring insang lingkar terdiri dari 8 panel ukuran mata jaring 1,75 inci dan 2,0 inci yang dipasang secara acak. Sampel ikan hasil tangkapan setiap aktual atau trip penangkapan diukur panjang total, untuk aspek reproduksi menggunakan 10-15% sampel ikan setiap trip, ikan diukur panjang total, berat tubuh dan dibedah untuk mengetahui jenis kelamin, tingkat kematangan gonad maupun berat gonad.  Hasil tangkapan jaring insang lingkar di dominasi family Caesionidae masing-masing jenis ikan Pteriocaesio tile 74,73%, Pterocaesio chrysozona 6,80% dan Caesio caerulaurea 6,41%. Distribusi ukuran panjang total ikan Pteriocaesio tile 15,0-27,3 cm. Ukuran ikan rata-rata pertama kali tertangkap mata jaring 1,75 inci adalah  21,4 cm dan 2,0 inci adalah 22,5 cm. Ukuran pertama kali matang gonad ikan betina 18,6 cm dan jantan  20,6 cm. Selektivitas jaring diperoleh peluang tertangkap 50% mata jaring 1,75 inci adalah 18,8 cm dan 2,0 inci adalah 21,9 cm. Status pemanfaatan sumberdaya ikan P tile berada dalam kondisi baik (Lc > Lm) tetapi penggunaan mata jaring 1,75 inci terindikasi mengalami recruitment overfishing.

Abstract

Poverty among fishermen is a complex problem and often occurs in many coastal areas and small islands. Fishermen depend heavily on fish catches for their income, however, they are very vulnerable to seasonal fluctuations, climate change, limited infrastructure, access to capital, social security and price competition. The factors faced by fishermen cause unstable economic conditions and make them vulnerable to poverty. This condition is also experienced by tuna handline fishermen in Haya Village, Central Maluku Regency. Community Service Activities (PKM) aim to identify problems with small-scale tuna handline fisheries and assist in the institutional formation of a Joint Business Group (KUB) for tuna handline fisheries in Haya Village. Implementation of activities begins with training, Participatory Rural Appraisal (PRA) and assistance in establishing KUB. This activity is in the form of a Forum Group Discussion (FGD) with partners and other stakeholders. Mitra is a small-scale tuna hand-line fisherman who has experience and is of productive age. The results of identifying partner and stakeholder problems through the Focus Group Discussion (FGD) method are decreasing fish resources, weak availability of facilities and infrastructure, low technology, weak institutions, and not yet optimal policy implementation. In this PKM activity, fishing operation management material is presented as material for gaining knowledge, experience and real conditions of fishermen management in handline fishing activities. All participants were very enthusiastic about taking part in this activity by providing feedback and suggestions for developing their fisheries business in the future. The implementation of the formation of Joint Business Groups (KUB) is expected to be able to overcome fishermen's problems, provide motivation, and be innovative and collaborative in groups. PKM activities were carried out well, apart from that, partners had increased capability, cooperation, communication and commitment within the group for fisheries business development.

Abstract

Gear selectivity is an important part of controlling the size of fish that are suitable for catching so that fish resources are maintained. The size of the hook is one of the factors that affect the selectivity of the fishing line. The purpose of this study is to analyze the selectivity of fishing lines on the results of catching Selar crumenopthalmus. Fish sampling was carried out by following a series of fishing operations by fishermen using hook sizes no. 17 and 18. The Holt method was used to analyze and calculate the selectivity of hook size operated by fishermen on the total length of the fish line. Size distribution of the total length of hook no. 17 in the middle-class size 16.5 cm – 22.5 cm and hook no. 18 in the middle-size class 16.5 cm – 20.5 cm. The distribution of length sizes on both hooks tends to be normally distributed and the proportion of large lengths is higher on hook no. 17. The 50% and optimal (100%) chance of being caught for hook size no. 17 is 18.3 and 20.1 cm, respectively. while the size of hook no. 18 is 167 cm and 18 cm. It is recommended to use hook size for trevally resources in the Seram Strait waters is hook no. 17.
