Abstract

The study aimed to identify species of reef fishes, to obtain indexes of diversity  and dominance, eveness and to analyze the comparison of communities between the two study sites by Sorensen similarity index. Data was gathered in-situ with underwater recordings at a depth of 6 meters assisted by diving apparatus, and using fish visual census method. Subsequent data were identified using  fish identifikaction guide and WoRMS (Word Register of Marine Science) online identification applications. The number of species and specimens of reef fishes from each study site after bein identified were then analyzed  the diversity, dominance and similarity of the community between the two study sites. The coral reef fishes identification results that obtained from each study site  were:  20 families, 86 spesies and 362 specimen at  Malalayang beach, and 15 families, 55 spesies and 217 specimen at Meras beach. The value of the calculated index o community structure obtained by H’ 3.42 (Malalayang) and 2.91 (meras) has been shown the ecological condition of coral reef ecosystem which is still stable even though diversity is moderate, but inversely with low dominance value (D=0.08). The coral reef fishes in both study sites were very diverse and there was no dominant species. Eveness of community between two study sites high.The result of community similarity analysis using Sorensen Index was 49 % (<50 %) indicates that there was no community similarity of coral reef fishes between Malalayang Beach and Meras Beach which was allegedly caused by natural factors and or anthropogenic one in both research sites.Keywords : coral reef fishes community, diversity, dominance, community similarity

Abstract

Generally, this study was intended to examine the problems or implementation of turtle conservation in Talise, Gangga and Bangka Islands and specifically with a number of objectives to: know the introduction of sea turtle, to know sea turtle fishing and turtle exploitation, to know the knowledge of the people about turtle as a protected animal. Survey results on Talise Island, Gangga and Bangka showed that people who had seen turtles directly: Talise Island 94%, Gangga 58%, and Bangka 92%. Local residents of Talise, Gangga and Bangka Islands know well the turtles even see directly in their habitat and spawning time. In Talise, Gangga and Bangka Islands,  turtles are still commonly caught, traded and consumed by local people.  People's awareness about turtles as protected animals is lacking.  Keywords: Turtle, Talise Island, Gangga and Bangka

Abstract

Hampir semua negara dan lembaga-lembaga konservasi resmi di dunia melarang perdagangan eksploitasi penyu. Penyu telah terdaftar dalam daftar Apendik I Konvensi Perdagangan Internasional Flora dan Fauna Spesies Terancam (Convention on International Trade of Endangered Species - CITES). Penyu terancam bahaya kepunahan karena tempat bertelur penyu mengalami degradasi. Tempat bertelur penyu belum terdokumentasikan dengan baik  di Sulawesi Utara sehingga perlu penelitian tentang lokasi bertelur penyu. Penelitian dimaksudkan untuk memetakan dan mendeskripsikan lokasi tempat bertelur penyu di Pantai Timur Kabupaten Minahasa, Provinsi Sulawesi Utara. Data diperoleh dengan survei dan wawancara warga yang tinggal di sekitar lokasi penelitian, mencakup Tiga wilayah kecamatan yaitu Kecamatan Kombi, Kecamatan Lembean Timur, dan Kecamatan Kakas. Hasil menemukan bahwa tempat bertelur terdapat di Pantai Ranowangko, Pantai Kawis, Pantai Toloun, Pantai Kolongan, Pantai Lembean, Kamenti, Atep Oki, Parentek, dan Pantai Tumpaan. Hampir semua kondisi lokasi bertelur penyu memiliki karakteristik yang mirip, yaitu garis pantainya yang panjang dengan di dominasi oleh pasir putih, daerah intertidal yang luas serta terdapat lamun. Sebagian besar penduduk yang tinggal di sekitar lokasi bertelur penyu pernah menangkap penyu, mengambil telur untuk dikonsumsi bahkan menjualnya.

Abstract

Padang lamun memilki berbagai peranan dalam kehidupan ikan dimana padang lamun dapat dijadikan daerah asuhan (nursery ground), sebagai tempat mencari makan (feeding ground), dan daerah untuk mencari perlindungan. Untuk spesies lamunnya sendiri dapat merupakan makanan langsung bagi ikan. Peranan lamun adalah sebagai daerah asuhan, dimana sebagian besar ikan penghuni padang lamun adalah ikan-ikan juvenil apabila telah dewasa akan menghabiskan hidupnya pada tempat lain.Jenis ikan yang yang di dapat pada padang lamun pantai Tongkaian dengan menggunakan survey jelajah dan alat tangkap gil net yaitu 10 jenis ikan. 10 jenis ikan yang di dapat pada saat penelitian di padang lamun pantai tongkaiana adalah umumnya penghuni daerah padang lamun dan ada juga ikan yang hanya mencari makan di daerah padang lamun atau ikan penghuni terumbu karang.Jenis lamun yang paling dominan di padang lamun pantai Tongkaina yaitu 2 jenis lamun. Kedua jenis lamun tersebut adalah lamun Enhalus acroides dan Thalassia hemprichii.

Abstract

There are a large variety and quite abundant types of small pelagic fish that have high economic value in the Sulawesi Sea. One of which is the blue scad fish or commonly known as malalugis (Decapterus macarellus). This study aims to analyze and determine the status of scad fisheries management and to develop recommendations in the management of scad fisheries in the waters of Sulawesi Sea, North Sulawesi Province. The evaluation of fishery management status is carried out using multi-criteria analysis (MCA) through the development of composite index of each indicator of Ecosystem Approach to Fisheries Management (EAFM). The results showed that, in general, the status of scad fisheries management in North Sulawesi Province, was in ‘good’ category, specifically reviewed from the domain of fish resources fall into the category of “medium”, habitat and ecosystem “good”, fishing techniques “good”, economy “not good”, social “medium” and institutional “good”. Management actions take precedence over domains that have “poor” indicator values. Priority management action is implemented in the economic domain, followed by the domain of fish resources, social, institutional and fishing techniques.Indonesian title: Pengelolaan perikanan ikan layang (Decapterus spp.) di perairan Laut Sulawesi, Provinsi Sulawesi Utara, menggunakan EAFM

Abstract

Bark of mangrove trees harbor populations of Littoraria scabra. The snails are preyed upon by aquatic and terrestrial predators. To investigate the main direction of predation, foui· Avicennia trees were seeded with 30 marked snails each. The snails were placed on trees variously protected by net cages: one tree with a fully closed cage to prevent access of all predators, one with a cage open above to allow entry of terrestrial predators, one with a cage open at the bottom to allow entry of aquatic predators. The fourth tree, without net, served as control. Snails were counted every 2 weeks. In the fully closed cage, the number of snails was relatively constant for 12 weeks, and survival was significantly different from the other trees. On the partly caged trees and the control tree, the number of snails declined drastically during the first four weeks. This indicates that aquatic predators (crabs), entering the tree from below, preyed on the Littoraria. Terrestrial predators, entering the tree trunk from above, are unknown.

Abstract

The purpose of this study was to classify the color of the shell and to know the carotenoid pigment content in Littoraria pallescens based on color classification and population distribution in the mangrove ecosystem area of Mokupa Village, Tombariri Sub district and Basaan Village, Ratatotok Sub district. Sampling directly on mangrove trees as water begins to recede. Identification of L. pallescens species is done by looking at the shape of the shell, the color of the shell, the color of the operculum and the shape of the genital organ. Shell color classification by inserting into the Color Explorer application. Analysis of carotenoid pigments by extraction process with acetone and petroleum ether, further separation of pigment by thin layer chromatography. The results obtained show that L. pallescence dominates life on mangrove trees. Sex was inversely proportional to the two research sites, 53.8% of the male L. pallescens species and 46.2% female in Mokupa waters while from Basaan waters there were 47.1% males and 52.9% females. Color classification based on the percentage of occurrences of constant color that is black (18.5), black orange (16.3) brown black spots (16,3), gray (10.7), angry (6,3), yellow pale (17.8), brown yellow spots (14,1). The detected pigment based on the color classification of the shell is located on the identical and identifiable Rf for all colors is the β-carotene pigment.Keyword : Littoraria pallescence, Carotenoid pigments Tujuan dari penelitian ini adalah untuk mengklasifikasikan warna cangkang dan mengetahui kandungan pigmen karotenoid pada Littoraria pallescens berdasarkan klasifikasi warna dan sebaran populasinya di wilayah ekosistem mangrove Desa Mokupa kecamatan Tombariri dan Desa Basaan Kecamatan Ratatotok.

Abstract

This study aims to get an overview of the intensity of predation on mangrove ecosystem in five marine protected areas (MPA), namely Tumbak, Basaan, Blongko, Bahoi and Tambun. The research method was carried out by installing Squidpops bait within one hour and calculating the number of lost bait during the exposure of baits in high tide. Fish species that migrate in the mangrove area are obtained through visual census; Mega Bentos is recorded.  The result of this study indicates the intensity of predation in the mangrove ecosystem in the five North Sulawesi DPLs are varied in each location, which has the possibility of being influenced by local condition, predatory fish population, the level of disturbance at observation, method and level of preference for the bait provided.Keywords: Predation, Predator, Mangrove, Fish Community, Squidpops ABSTRAKPenelitian ini bertujuan untuk mendapatkan gambaran intensitas predasi pada ekosistem mangrove di lima daerah perlindungan laut (DPL), yaitu Tumbak, Basaan, Blongko, Bahoi dan Tambun.
