Abstract

Threadfin breams (Nemipteridae) are demersal fish species that constitute a significant catch for East Nusa Tenggara fishermen at the Oeba Fish Landing Site and Oesapa Fish Market, where they are landed year-round. Over the years, there has been a noticeable increase in the capture of threadfin breams, raising concerns about the potential impact on their genetic diversity. The ongoing trend could affect the region’s overall population structure of threadfin breams. This study addresses the need to identify threadfin breams in the landing above sites of threadfin breams through molecular analysis of mtDNA COI. The research involved the examination of 24 samples obtained from the Oeba Fish Landing Site and Oesapa Fish Market. The analysis revealed the presence of five distinct threadfin bream species: Nemipterus hexodon, N. japonicus, N. zysron, N. aurora, and Pristipomoides typus. The genetic distance between individual threadfin breams ranged from 0-0.8%, indicating a relatively close genetic relationship within the population. Also, phylogenetic tree reconstruction further delineated five distinct clades based on the species obtained from the samples. Given these findings, the study emphasizes the importance of sustainable threadfin bream capture to preserve genetic diversity. The results underscore the need for ongoing monitoring and management strategies to ensure the threadfin bream population’s long-term health and stability. Additionally, the study suggests that a more in-depth analysis of genetic diversity and the environmental factors influencing this species is warranted for a comprehensive understanding and effective conservation measures.

Abstract

The threadfin bream fish from the Nemipteridae family is a demersal species and an economically significant commercial fish. It is widely used for personal consumption and sold in markets. The capture of threadfin bream fish at the Oeba Fish Landing Site and Oesapa Fish Market has been increasing. Continuous high-intensity fishing will likely negatively impact the threadfin bream fish population, leading to stock depletion and reduced catch production. Research on threadfin bream fish in East Nusa Tenggara has yet to be reported, particularly in Kupang Bay and Rote Ndao waters. This study aims to investigate the fisheries biology of threadfin bream fish landed at the Oeba Fish Landing Site and Oesapa Fish Market. A total of 84 threadfin bream fish were sampled from both locations. The length-weight relationship of threadfin bream fish at these sites is negatively allometric with value b < 3, indicating that length growth is more dominant than weight gain. The gonad maturity stages of male and female threadfin bream fish range from GSM I-III. The size distribution of threadfin bream fish ranges from 173-295 mm at the Oeba Fish Landing Site and from 173-245 mm at the Oesapa Fish Market. Most of the threadfin bream found are still in the early stages of gonadal maturity, indicating that these fish are young and not yet ready to spawn. Implementing Sustainable fishing management practices is crucial, including setting catch quotas and minimum catch sizes and educating fishermen to ensure the sustainability of threadfin bream fish stocks.

Abstract

Ekonomi Biru (blue economy) merupakan suatu pendekatan transformatif dalam mengoptimalisasi sumber daya laut secara berkelanjutan demi mendukung pertumbuhan ekonomi dan kesejahteraan masyarakat, terutama wilayah pesisir. Berdasarkan hasil survey dan FGD, diketahui bahwa Kelompok Usaha Perempuan Nelayan “Parma Bahari” belum memiliki pengetahuan dasar terkait diversifikasi hasil perikanan, keterbatasan sarana pengolahan, sistem pemasaran produk hingga legalitas kelembagaan kelompok yang belum memiliki izin. Kegiatan pengabdian dilakukan pada Kelompok Perempuan Parma Bahari yang bertempat di Kelurahan Kamalaputih, Kabupaten Sumba Timur. Tahapan kegiatan pengabdian meliputi survey lokasi, FGD, implementasi kegiatan dengan pendekatan Participatory Rural Appraisal (PRA) dan analisis kepuasan. Hasil pengabdian menunjukkan implementasi difusi IPTEK yang meliputi sosialisasi, pelatihan, pendampingan dalam diversifikasi pengolahan hasil perikanan, manajemen pemasaran dan kelembagaan kelompok hingga legalitas usaha memberikan dampak keberdayaan terhadap Mitra Kelompok Usaha Perempuan Nelayan “Parma Bahari”. Difusi IPTEK tersebut mampu memberikan pemahaman kepada masyarakat pesisir dalam mengoptimalisasikan sumber daya perikanan melalui hilirisasi olahan perikanan dalam mendukung implementasi “blue economy”. Mitra “Parma Bahari” saat ini telah memiliki sarana alat pengolahan ikan, legalitas usaha produk (NWPW, NIB- SP-PIRT) hingga legalitas kelompok usaha yang telah terdaftar secara resmi di Pemerintah Daerah Kabupaten Sumba Timur. Aspek kepuasan Mitra terkait pelayanan pengabdian seperti bantuan sarana pengolahan, pelatihan dan sosialisasi mencapai 81,82%. Selain itu, kegiatan pengabdian yang dilakukan juga memberikan pengalaman belajar yang baik terhadap mahasiswa melalui implementasi Merdeka Belajar-Kampus Merdeka (MBKM).
