Abstract

Coral reefs are communities of organisms that live at the bottom of shallow seas of tropics area. Degradation of coral reefs in the waters of Pulau Lembeh, Bitung caused by fishing activities were not responsible. However, there have been attempts to build artifial reefs since 2014 to protect natural coral reefs as well as repairing the damaged coral reefs. It is necessary to hold monitoring association of fish species target on artificial reef has been built with Acropora sp. trasnplantated. This research was conducted in Mawali Village, Lembeh Strait, on August - December 2016; done with descriptive method; and the data were analyzed through the diversity and richness index. Results of the analysis showed that the diversity of species classified as moderate with a value of 2.85; and species richness is high with a value of 6.09. This figure reflects the dominance of Cheilodipterus isostigmus species to other species in terms of number. Oceanography parameters such as temperature (26,99 – 28,97°C), salinity (32 – 33,2 ppt), dissolved oxygen (10,2 – 12,4 mg/l), acidity (7,3 – 8,4 pH), dissolved density (30,4 – 31,1 g/l ) and level of turbidity (1,2 – 2,6 NTU) in natural conditions support the development of the association of fish around the artificial reefs. Keywords: Monitoring, Fish Species Target, Artificial Reefs, Lembeh Strait, Mawali Village ABSTRAK Terumbu karang merupakan komunitas organisme yang hidup di dasar laut dangkal daerah tropis. Degradasi terumbu karang di perairan Pulau Lembeh, Kota Bitung disebabkan oleh aktifitas perikanan yang tidak bertanggungjawab. Namun telah ada upaya pembangunan terumbu buatan sejak tahun 2014 untuk melindungi serta memperbaiki terumbu karang alami yang rusak. Maka dipandang perlu mengadakan monitoring asosiasi ikan target pada terumbu buatan yang telah dibangun dengan karang yang ditransplantasikan jenis Acropora sp.  Penelitian ini dilakukan di Selat Lembeh Kelurahan Mawali pada bulan Agustus – Desember 2016; dikerjakan dengan metode deskriptif; dan data dianalisis melalui indeks keragaman dan indeks kekayaan.  Hasil analisis menunjukan bahwa keanekaragaman spesies tergolong sedang dengan nilai 2,85; dan kekayaan spesies tergolong  tinggi dengan nilai 6,09. Hal ini menggambarkan adanya dominasi spesies Cheilodipterus isostigmus terhadap spesies lain dari segi jumlah. Parameter oceanografi seperti suhu (26,99 – 28,97°C), salinitas (32 – 33,2 ppt), oksigen terlarut (10,2 – 12,4 mg/l), derajat keasaman (7,3 – 8,4 pH), kepadatan terlarut (30,4 – 31,1 g/l ), dan tingkat kekeruhan (1,2 – 2,6 NTU) dalam kondisi alami menunjang perkembangan asosiasi ikan di sekitar terumbu buatan.

Abstract

Swimming crab (Portunus pelagicus) is one of the fishery commodities that have high sales value for which raced flavor and high nutritional content. This swimming crab in coastal waters of North Sulawesi usually caught accidentally (by catch) with bottom gillnets. There has been a special fishing gear for crab traps, but not known by local fishermen. The differences of trap shape could increase the fishing power of swimming crab traps; but such scientific information is not widely available yet. Therefore, this research aimed to study the effect of pots shape to catch swimming crab; and identifies the types of biota captured. This research was conducted in the coastal waters of  Kema Tiga village, North Minahasa Regency; from September to December 2014; which is based on the experimental method. Bubu six units of traps (three units conical shape, and three other rectangular shape), operated for eight nights to collect data; used scad mackerel bait; and the capture data were analyzed by t test.  The catch was 86 swimming crab in total; 56 was caught by conical shape traps, and 30 individuals were caught by rectangular shape traps. Analysis of test showed that t0 = 4.596> t table 0.01; 7 = 3.499, which means that the use of conical shape traps, giving highly significantly different swimming crab catches compared to rectangular shape traps. Keywords: Swimming crab, trap, mackerel bait, North Minahasa   ABSTRAK Rajungan (Portunus pelagicus) merupakan salah satu komoditi perikanan yang memiliki nilai jual tinggi karena memiliki rasa yang lezat dan kandungan gizi yang tinggi). Rajungan  ini di perairan pantai Sulawesi Utara biasanya tertangkap tanpa sengaja (by catch) dengan jaring insang dasar. Sebenarnya telah ada alat tangkap bubu khusus untuk rajungan, tetapi belum dikenal oleh nelayan lokal. Perbedaan bentuk bubu diduga dapat meningkatkan kemampuan tangkap dari bubu ranjungan; namun informasi ilmiah seperti ini belum banyak tersedia. Oleh karena itu, penelitian ini bertujuan untuk mempelajari pengaruh bentuk bubu terhadap hasil tangkapan ranjungan; dan mengidentifikasi jenis-jenis biota yang tertangkap.  Penelitian ini dilakukan di perairan pantai Desa Kema Tiga, Kabupaten Minahasa Utara; pada bulan September sampai Desember 2014; yang didasarkan pada metode eksperimental. Enam unit bubu (tiga unit bentuk kerucut terpancung dan tiga unit bentuk empat persegi) dioperasikan selama delapan malam untuk mengumpulkan data; menggunakan umpan ikan layang; dan data dinalisis dengan uji t. Tangkapan total berjumlah 86 ekor; 56 ekor tertangkap dengan bubu bentuk kerucut terpancung, dan 30 ekor tertangkap dengan bubu bentuk empat persegi. Hasil analisis menunjukan bahwa t hitung = 4,596 > t tabel 0,01;7 = 3,499, yang berarti bahwa penggunaan konstruksi bubu bentuk kerucut terpancung, memberikan hasil tangkapan rajungan yang sangat berbeda nyata dibandingkan dengan konstruksi bubu empat persegi. Kata-kata kunci: Rajungan, bubu, umpan ikan layang, Minahasa Utara.

Abstract

Fishing boat has unique characteristics, such as seaworthiness, maneuvering, boat’s velocity, displacement, fishing gear layout, and catch storage facilities. With increasing development of photographic technology, photography is not merely an art but it has become a field of mathematics, making it a technique that can be integrated with software technology designed to produce digital data objects in the form of 3D images called Photogrammetric technique. This study is to obtain the reconstruction of the boat's hull based on the Photogrammetric software, to determine the effect of photography to obtain a 3D image, and to know the weakness and strength of 3D reconstruction of the boat’s hull. The images in this study were obtained using a POCO F3 smartphone camera integrated with the PIX4Dcatch application and analyzed with Agisoft Metashape Professional (Trial Version). From this research, we concluded that 1) the reconstruction of the boat hull can be obtained by using Photogrammetric techniques in the PIX4Dcatch application followed by the Agisoft Metashape Professional (Trial Ver.) software analysis; 2). With photographic equipment and several data processing software, the boat’s shape could be produced in 3D images, and 3). There are several advantages in reconstructing the ship's hull with the Photogrammetric technique, namely producing the ship's reconstruction of 3D images, obtaining the principal dimensions of the boat, such as the area and volume of the boat, that could be as the basic data for boat resistance and ship stability calculation, and the work could be done by one person only.

Abstract

The aim of this research is to determine the differences between two types of artificial bait on troll line on catches and to identify the composition of catch types based on bait type. This research was carried out in Tanawangko waters and was carried out from February to March 2023 using the experimental fishing method, where two pancing tonda  each using silk fiber and chicken feather bait were operated simultaneously in one boat for 5 trips which were then analyzed using the t test. The catch during the research was 24 individuals with 3 species, namely with silk fiber bait, 20 individuals were caught consisting of 3 species and using chicken feather bait, 4 individuals were caught consisting of 2 species. The analysis results show that tcount = 1.684 < t table = 2.776; so it accepts H0 and rejects H1. This explains that the use of chicken feather bait is not significantly different from silk fiber as trolling bait for catch results. The conclusion of this research is that using silk fiber bait resulted in more catches than chicken feather bait, but the results of the t test analysis showed that the two were not significantly different and the three species of fish caught were 15 skipjack tuna (Katsuonus pelamis), 7 baby tuna (Thunnus sp.), and 2 lemadang (Coryphaena hippurus).
