Abstract

Penelitian ini dilakukan pada Bulan April 2019 dengan tujuan untuk menganalisis kondisi kesehatan terumbu karang dan kondisi kesehatan ekosistem terumbu karang di Perairan Kawasan Mandeh. Penelitian ini dilakukan dengan menggunakan metode survey dimana setiap pulau terdiri atas 3 stasiun dengan tiap stasiun terdiri atas 2 kedalaman yaitu 4 meter dan 9 meter. Pengambilan data persentase tutupan karang dan tingkat resiliensi karang yang dinilai berdasarkan persentase patahan karang dilakukan dengan metode Underwater Photo Transek (UPT), Sedangkan pengambilan data ikan dilakukan dengan metode Underwater Visual Census (UVC). Berdasarkan hasil penelitian yang dilakukan diketahui bahwa kondisi kesehatan terumbu karang yang paling baik disekitarnya adalah Pulau Marak.  Sedangkan kondisi kesehatan terumbu karang yang terburuk adalah Pulau Pagang. Ukuran dalam menentukan kondisi kesehatan terumbu karang karang didasari oleh sehatnya terumbu karang itu sendiri dan ekosistemnya. Terumbu karang yang sehat memiliki persentase tutupan karang batu hidup yang tinggi dan disertai oleh tingginya tingkat resiliensi atau pemulihan yang dimiliki hewan karang saat mendapat gangguan. Sedangkan ekosistem terumbu karang yang sehat adalah terumbu karang yang mampu memproduksi sumberdaya ikan sebanyak-banyaknya.

Abstract

AstractOne of the biota that lives in mangrove ecosystems is the gastropod telescopium telescopium. Telescopium telescopium has more active behavior at spring tide (high tide and low tide) than low tide (low tide and high low tide). The weight of the gonad will reach a maximum of a moment when the mangrove snail will spawn, then the weight of the gonad will decrease rapidly as long as the spawning is in progress until complete. This research was carried out in June-July 2018, sampling in the mangrove ecosystem of Ketapang Beach waters, Sungai Cingam Village, Rupat District, Bengkalis Regency, Riau Province. The samples were analyzed at the Marine Biology Laboratory of the Faculty of Fisheries and Marine Sciences, Riau University. This study aims to determine the population structure of gonad maturity index and habitat conditions of T. telescopium gastropods in Ketapang Beach waters, Sungai Cingam Village, Rupat District. The method used in this research is survey method. Measurement of water quality parameters is carried out in situ, namely temperature, and determination of sampling locations by purposive sampling, salinity and pH, type of substrate in sandy mud dominance. Water quality parameters are still supportive for the life of mangrove snails. Average density of Tcopcopium T in the mangrove forest of Sungai Cingam Village is low. There were no differences in density between the research stations but there were differences in density between the study zones. The average distribution pattern of T. telescopium is clustered. The size of T. telescopium found ranged from 38-87 mm. The main habitat of T. telescopium is in zone 2 (lowere zone).Keywords: Population structure, Telescopium telescopium, Rupat Island.
