Abstract

The black pearl oyster Pinctada margaritifera (Linnaeus, 1758) or black lip pearl oyster is a marine bivalve with important economic value. P. margaritifera is a protandrous hermaphroditic species. Externally it is difficult to differentiate between male and female gonads. This research aimed to determine differences in gonad color and determine the sex of P. margaritifera based on shell size. The test animals used in this research were black pearl mussels P. margaritifera totaling 33 samples taken from Talengen Bay, Sangihe Islands Regency, North Sulawesi. The results of morphometric measurements showed the average shell length was 103.16 mm, where the maximum shell length was 131.61 mm and the minimum was 81.29 mm. The average shell width was 105.65 (max 141.17 mm-min 83.21mm), the average shell thickness was 32.46 mm (max 44.36, min 20.11mm). The gonads were white and slightly yellow in 24 males and yellow in 9 females. P. margaritifera with a shell length of 90-130 mm was found to be female, and most were 110-120 mm in size. Meanwhile, shell lengths <80 mm and 110-130 mm male pearl oysters were still found. Keywords: marine bivalve, growth rate, morphometric, shell length

Abstract

Coral reefs are one of the most productive and diverse ecosystems on earth and provide ecosystem services. One of the islands of the Seribu Islands that has a coral reef ecosystem is Tidung Island. It is strategic and developing location makes this island used as a residential area, conservation area, and tourist destination. But the utilization has an impact on the damage of coral reefs through environmental and anthropogenic pressures. This study aims to determine coral diversity by identifying the coral genus Scleractinia and the factors that affect coral diversity. Observations were done on three different stations include 2 snorkeling areas and 1 natural area. The method used is LIT (Line Intercept Transect) and coral genus identification with Coral Finder Toolkit Indo Pacific 3.0. The results of identification obtained 16 coral genera namely genus Acropora, Montipora, Isopora, Favites, Leptastrea, Favia, Goniastrea, Montastrea, Platygyra, Echinopora, Porites, Pocillopora, Stylophora, Ctenactis, Pavona, dan Symphyllia, with the value of Diversity Index (H') in the waters of Tidung Island ranges from 0.94 – 2.34  in the category of low to moderate diversity. The parameters of water quality in Tidung Island, temperature, salinity, and acidity (pH) are relatively good for coral growth, but brightness is still relatively poor for coral growth. The impact of human activities such as snorkeling, ship anchors, fishing with destroyers, oil and waste pollution, and rock mining are factors that affect coral growth and diversity.Keywords: Coral Scleractinia; Limiting Factors; Coral Finder; Tidung IslandAbstrakTerumbu karang adalah salah satu ekosistem yang paling produktif dan beragam di bumi serta menyediakan jasa ekosistem. Salah satu pulau dari gugusan Kepulauan Seribu yang memiliki ekosistem terumbu karang yaitu Pulau Tidung. Letaknya yang strategis dan berkembang menjadikan pulau ini dimanfaatkan sebagai kawasan permukiman, daerah konservasi, dan kawasan tujuan wisata. Namun dari pemanfaatan tersebut memberikan dampak terhadap kerusakan pada terumbu karang melalui tekanan-tekanan lingkungan maupun antropogenik. Penelitian ini bertujuan untuk mengetahui keanekaragaman karang dengan mengidentifikasi genus karang Scleractinia dan faktor yang mempengaruhi keanekaragaman karang. Pengamatan di tiga stasiun berbeda yaitu di antaranya 2 kawasan wisata snorkeling, dan 1 kawasan yang masih alami. Metode yang digunakan yaitu LIT (Line Intercept Transect) dan identifikasi genus karang dengan Coral Finder Toolkit Indo Pasific 3.0. Hasil identifikasi didapatkan 16 genus karang yaitu genus Acropora, Montipora, Isopora, Favites, Leptastrea, Favia, Goniastrea, Montastrea, Platygyra, Echinopora, Porites, Pocillopora, Stylophora, Ctenactis, Pavona, dan Symphyllia, dengan nilai Indeks Keanekaragaman (H’) di perairan Pulau Tidung berkisar 0,94 – 2,34 berada pada kategori keanekaragaman rendah hingga sedang. Parameter kualitas perairan di Pulau Tidung, suhu, salinitas, dan derajat keasaman (pH) tergolong baik bagi pertumbuhan karang, namun kecerahan masih tergolong kurang baik bagi pertumbuhan karang. Dampak aktivitas manusia seperti snorkeling, jangkar kapal, penangkapan ikan dengan alat perusak, pencemaran minyak dan sampah, serta penambangan batu karang menjadi faktor yang mempengaruhi pertumbuhan dan keanekaragaman karang.

Abstract

The research purposes were to determine the best initial weight of Caulerpa lentillifera algae, determine the appropriate cultural operational depth for the best growth of C.lentillifera algae, and determine the interaction between the initial weight factor of C.lentillifera algae and the depth factor of growth. This research was carried out from May to July 2023. The C. lentillifera algae in this research were obtained from nature. C.lentillifera algae culture is carried out using the verticulture method, namely tying the algae to strings arranged in a row. This research was designed using a 3x3 factorial in a Completely Randomized Design (RAL). There are 2 factors tested in this experiment, each of which has 3 levels, namely: the weight factor of C. lentillifera algae which consists of: A1 = 50 grams, A2 = 100 grams and A3 = 150 grams, and the depth factor which consists of: B1 = 20 cm, B2 = 70 cm and B3 = 120 cm. The results obtained from this research are that differences in the growth of C. lentillifera algae are very significantly influenced by differences in the initial weight of different. The best absolute growth, relative growth, and daily growth rate were initial C. lentillifera algae weights of 50 grams, which respectively had the highest average values of 24.3 grams, 16.2%, and 1.4%. Differences in depth had no significant influence on differences in absolute growth, relative growth, and daily growth rate of the algae C. lentillifera. The results of variance analysis showed that the influence of the weight factor of C. lentillifera on absolute growth, relative growth, and daily growth rate did not change significantly when the depth factor level was changed.

Abstract

Indonesia is a tropical country with high marine biodiversity, including sea cucumber. The high demand for sea cucumber has led fishermen to catch sea cucumber regardless of the type or size suitable for harvesting. The lack of cultivation and regulations governing the protection of sea cucumbers has caused some species to be endangered. Sea cucumber species with high selling prices are increasingly difficult to find in West Likupang District. This study aims to identify strategies for managing sea cucumber fisheries sustainably and provide policy recommendations for their sustainable management in West Likupang District. This study used a survey method and then analyzed it with a SWOT analysis (strengths, weaknesses, opportunities, threats). The SWOT analysis reveals several strategies for achieving sustainable sea cucumber fisheries: legislation, conservation efforts, aquaculture development, regulated fishing, proper post-harvest handling, and educating fishermen on regulations. Keywords: Management, regulation, conservation, sea cucumber, SWOT Abstrak Indonesia merupakan negara tropis yang mempunyai keanekaragaman hayati laut yang tinggi, salah satunya ialah sumber daya trepang (Holothuridea). Permintaan pasar yang tinggi terhadap trepang, menyebabkan nelayan menangkap trepang tanpa mengindahkan jenis dan ukuran yang layak panen. Belum adanya budi daya dan regulasi yang mengatur perlindungan terhadap trepang menyebabkan beberapa spesies sudah terancam punah. Spesies trepang dengan harga jual yang tinggi makin sulit ditemukan terutama di Kecamatan Likupang Barat. Penelitian ini bertujuan untuk menentukan strategi pengelolaan sumber daya perikanan trepang, untuk mencapai perikanan trepang yang berkelanjutan, dan membuat rujukan atau rekomendasi kebijakan untuk pengelolaan sumber daya perikanan trepang (Holothuroidea) yang berkelanjutan secara umum Di Provinsi Sulawesi Utara, khususnya di Likupang Kabupaten Minahasa Utara. Penelitian ini menggunakan metode survei kemudian dianalisis dengan analisis SWOT (kekuatan, kelemahan, peluang, dan ancaman). Berdasarkan hasil analisis, terdapat beberapa strategi yang dapat dikembangkan untuk mencapai perikanan trepang yang berkelanjutan, yakni: regulasi berupa peraturan perundangan, upaya konservasi, pengembangan usaha budidaya, penangkapan yang terukur, penanganan pasca panen/penangkapan dari alam, dan sosialisasi kepada nelayan terkait peraturan Kata kunci: Pengelolaan, regulasi, konservasi, trepang, SWOT
