Abstract

Ikan karang merupakan salah satu komponen biotik yang menjadi tolak ukur kondisi keanekaragaman hayati di ekosistem terumbu karang. Perubahan kondisi dasar perairan yang disebabkan baik oleh aktivitas alami maupun antropogenik mampu mengubah kondisi kelimpahan dan keragaman ikan karang yang ada di suatu wilayah. Begitu juga dengan perubahan kelimpahan ikan karang yang dapat berdampak pada penurunan kualitas ekosistem itu sendiri. Tujuan dari penelitian ini adalah untuk memberikan gambaran mengenai kondisi tingkatan trofik ikan karang  dan hubungannya dengan kondisi dasar perairan di Selat Sempu. Pengambilan data dilaksanakan di Selat Sempu pada Bulan November 2019 pada tiga stasiun menggunakan metode Roving Diver Technique (RDT). Hasil penelitian menemukan 721 individu ikan karang dari 76 spesies dan 25 famili, dimana famili Chaetodontidae, Pomacentridae, dan Labridae yang merupakan famili dengan kelimpahan spesies tertinggi. Stasiun Tiga Warna memiliki tutupan karang hidup tertinggi, yang berhubungan dengan kelimpahan ikan corallivore yang tinggi. Meski demikian, korelasi antara tutupan karang keras dan ikan corallivore menunjukkan hubungan yang lemah (R2=0,2045). Sementara korelasi antara kelimpahan ikan herbivore dan tutupan karang dengan alga menunjukkan korelasi yang kuat (R2=0,9843). Dengan demikian, diketahui bahwa keragaman tutupan dasar perairan memiliki pengaruh terhadap kelimpahan tingkat trofik ikan karang tertentu di suatu wilayah.

Abstract

The fisheries sector is one of the sectors with great potential for the Indonesian economy. East Java has a large fishing enterprise, which is due to the spread of fish landing bases and an active role in promoting local fishing production, one of which is the beach fishing port (PPP) Pondokdadap. The aim of this study is to obtain information on the types and volumes of fish production captured in the PPP Pondokdadap in May and June 2022. The method used by the author in conducting this research is a qualitative-descriptive approach. According to the results of research, during May 2022, the production of fish captured in PPP Pondokdadap amounted to 1,813 tonnes. In June, the capture amounted to 1,605 tonnes. There was a decrease in production volume of 207 tonnes, or about 11%. There are 10 species of fish captured, dominated by tuna

Abstract

The fishing port, which acts as a public agency, provides services and facilitates fishing activities for fishermen. One indicator that the service provided is already optimal is the minimum number of vessels in the process of dismantling fish in the port. The study aims to find out the fishing landing system and the number of ships that landed during the period September–August 2022. The method used is directly through field observations and collecting secondary data to supplement the data obtained. The system applied to each port is different. The port of Pondokdadap applies the queue method as well as the system of nahkoda, where the ship's documents must be submitted and the fisherman's number taken before landing. Boats that want to sell fish to the TPI must be equipped with a catch letter. In the period September–August 2022, the highest number of ships was found in June 2022, with 603. For the smallest number in January 2022, there were 22 ships. Based on the results obtained, it is known that the period of April–September has the highest number, while there is a decrease in the number in October–March. There was an increase in the number of vessels that carried out fishing, which was affected by the fishing season, with the high season in the Eastern season.
