Abstract

Nelayan desa Dullah laut sangat menggantungkan hidupnya pada kawasan perairan pulau adranan, kawasan ini dikenal sebagai kawasan wisata bahari karena selain memiliki pasir putih juga memiliki keanekaragaman terumbu karang dalam jumlah yang banyak, sehingga sering disebut juga sebagai surganya wisatawan dan nelayan karena menyajikan keindahan terumbu karang dan beragam jenis ikan karang serta cumi. Permasalahan dalam beberapa tahun terakhir telah terjadi pengurangan jumlah tangkapan nelayan (ikan dan cumi), akibat kegiatan illegal fishing (menggunakan jaring pukat harimau, racun serta peledak), hal ini mengakibatkan banyak sekali terumbu karang rusak dan mati. Tujuan kegiatan ini adalah untuk menerapkan teknologi rumpon hybrid pada kawasan laut pulau adranan sebagai sarana perbaikan habitat terumbu karang dan mengembalikan kembali daerah penangkapan. Metode yang digunakan adalah pelatihan pembuatan dan penanaman rumpon hybrid dan monitoring habitat. Hasil Kegiatan berupa 2 unit rumpon hybrid yang telah diletakan pada perairan pulau adranan, dan setelah dilakukan monitoring, terlihat secara signifikan hasil pertumbuhan transplantasi terumbu karang pada lokasi penanaman rumpon dan ikan-ikan herbivora seperti ikan botana dan ikan baronang serta cumi sudah mulai menempati lokasi sekitar rumpon. Sesuai harapan kedepannya lokasi ini akan kembali menjadi daerah penangkapan baik untuk ikan maupun cumi

Abstract

The economic value of sea cucumbers is high in the market and is similar to other fishery commodity products. The high economic value causes the fishing effort to increase. The level of fishing that is not balanced with the availability of resources can threaten the existence of the population. This study aims to examine the density, size distribution, distribution pattern, population presence and growth pattern of sea cucumbers in Letman waters. The sampling method is a random method. The sea cucumbers found at the research site consisted of 8 species with a density range of 0.04-0.24 ind/m2. The results of measurements of temperature, salinity and pH at the study site obtained temperatures ranging from 29-31°C, salinity ranging from 28-31‰ and pH ranging from 8.11-8.26. The length of the sea cucumbers ranges from 10.5-31.52 cm, the diameter size ranges from 3.00-10.03 cm and the weight size ranges from 51.5-611.09 gr. The distribution pattern of sea cucumbers is grouped with an Id value of 1.23. The existence of sea cucumbers showed a low diversity value (H' = 0.42), low uniformity (E = 0.234) and the dominance was classified as stable (C = 0.83). The growth pattern of sea cucumbers obtained a b value of 2.16 so that it is classified as negative allometric (b < 3).

Abstract

Fishermen in Hoat Sorbay Sub-district, Southeast Maluku Regency are dependent on the sea, this sub-district has potential waters with many fish resources because located in ten archipelagic waters which potential famous for reef fish and migration route for leatherback turtles. The high level of fishing activities followed by mores illegal activities. Generally, they uses explosives, poison, trawl nets, and cause the coral reefs damaged, then fishermen's catches will decreases. This study aims to repair the coral reefs damaged, provide training and counseling to preserving the marine environment. We use methods training, counseling and mentoring in this study and gives output 24 units of reef ball and biorock fish apartment placed in the waters of Warhu Island. Monitoring found that several types of fish such as the Acanthuridae family or surgeonfish or botana fish have occupied the biorock or fish apartment. In addition, there are fish with the Siganidae family or baronang fish and also a little bit of carnivorous fish species such as Lethrinidae family or lencam fish. In the future, the waters area of Warhu Island will become a new fishing ground, because more of the fish are the target of fishermen’s catches.
