Kahyapu Waters is one of the potential waters for demersal fishing in Enggano Island. Demersal fish resources in Kahyapu Waters if exploited optimally can provide sustainable benefits for local fishermen. Target strength is one of the most important parameters in estimating fish stocks because this value is a scale in estimating the potential of fish resources. This study aims to analyze the average value of target strength (TS) of demersal fish through in-situ acoustic measurements, and describe the distribution of TS of demersal fish in Kahyapu. Data were collected using Simrad EK15 echosounder by following the cruise track in the form of 8 zigzag transects and divided into 32 ESDU (Elementary Sampling Distance Unit). The results showed that the TS value of demersal fish had an average value of -48.93 dB with a range of values ranging from -67.34 dB to -38.77 dB with an estimated fish body length ranging from 1.08 to 28.91 cm. Spatial distribution of demersal fish target strength with the lowest depth of 6.4-16.9 m is located in ESDU 12 and ESDU 11 and the highest depth is 25.9-32.4 m located in transect 3 distribution of desmersal fish with the highest TS dominated scattered at a depth of 19.4-25.9 m. Perairan Kahyapu merupakan salah satu perairan yang potensial untuk penangkapan ikan demersal di Pulau Enggano. Sumber daya ikan demersal di Perairan Kahyapu apabila dieksploitasi secara optimal dapat memberikan manfaat yang berkelanjutan bagi nelayan lokal. Target strength merupakan salah satu parameter yang sangat penting dalam pendugaan stok ikan karena nilai ini merupakan skala dalam pendugaan potensi sumberdaya ikan. Penelitian ini bertujuan untuk menganalisis nilai rata-rata target strength (TS) ikan demersal melalui pengukuran akustik secara in-situ, dan menggambarkan distribusi TS ikan demersal di Kahyapu. Pengambilan data menggunakan echosounder Simrad EK15 dengan mengikuti jalur pelayaran berbentuk transek zig-zag sebanyak 8 transek dan dibagi menjadi 32 ESDU (Elementary Sampling Distance Unit). Hasil penelitian menunjukkan bahwa nilai TS ikan demersal memiliki nilai rata-rata -48.93 dB dengan rentang nilai berkisar -67.34 dB sampai -38.77 dB dengan dugaaan panjang tubuh ikan berkisar 1.08 sampai 28.91 cm. Distribusi Target strength ikan demersal secara spasial dengan kedalaman terendah 6,4-16,9 m terletak di ESDU 12 dan ESDU 11 dan kedalaman tertinggi adalah 25,9-32,4 m terletak di transek 3 sebaran ikan desmersal dengan TS tertinggi didominansi tersebar di kedalaman 19,4-25,9 m.

“…The distribution of trevally catches in other areas, such as in Pangkajene Waters, South Sulawesi that many trevally are caught because the substrate type is muddy sand (Akbar et al, 2017). In Youtefa Bay Waters, Jayapura City, trevally is mostly caught because of the basic substrate and water depth factor (Pujiyati et al, 2020).…”

Fisheries data statistics play an important role in fisheries management. The data collection might be provided at landing sites. However, not all landing sites can provide fisheries data. Kandangsemangkon small landing site is an unreported landing site that lands various economically important species; one of species is The trevally fishery. The purposes of this study were to identify the species landed, determine the categorization of species supporting the landed trevally fishery, and determine the trevally fishing area and the volume of trevally production that was not recorded or reported at Kandangsemangkon Small Landing Site. The data collection method of this study is the descriptive survey method, which involves taking primary and secondary data. The primary data collection was carried out by interviewing fishermen regarding the species of the catch landed and the trevally fishing area and observing the research location. The secondary data used was the production data of Trevally landed at Brondong Fishing Port. The results of this study show that there were three types of target species, secondary species, primary species, and no endangered, threatened, or protected species were found. The trevally fishing grounds are generally in WPPNRI 712 and 713. The volume of unrecorded and unreported production was 46.70% and did not contribute to the fisheries statistics of Lamongan, East Java.
