“…Several methods can be employed to estimate fishery resource potential, one of which is the acoustic method in fishery resource estimation [9][10][11][12][13]. The application of acoustic methods in fish stock estimation offers several advantages, including the rapid generation of in-situ data, relatively accurate results, and non-invasiveness to the observed fishery resources.…”

Fisheries resource assessment is pivotal for grasping marine ecosystem dynamics and guiding sustainable management practices. This study focuses on exploring the fisheries resources within Berau Bay, situated in the biodiverse-rich West Papua Province, known for its significant marine biodiversity and importance to local livelihoods. Despite its importance, there is a notable absence of comprehensive assessments concerning the bay’s fisheries resources and their utilization potential. This research endeavors to fill this gap by providing a detailed analysis to inform sustainable management strategies. Our findings reveal a diverse range of fish families dominating Berau Bay, with significant contributions from Carangidae and Scombridae. Moreover, acoustic surveys uncover substantial Fisheries Resource Potential (FRP) across three zones: Zone 1 at 501.555 tons, Zone 2 at 854.634 tons, and Zone 3, primarily designated as a conservation area, at 678.188 tons. The cumulative FRP potential amounts to 2.034.377 tons, encompassing various species categories, with an estimated annual utilization rate of around 1.627.502 tons. These results challenge previous assumptions regarding the bay’s fisheries composition and potential, emphasizing the necessity of updated assessments. Additionally, they enhance our understanding of the region’s marine biodiversity, underscoring the urgency of targeted conservation efforts for sustainable resource management. This study emphasizes the significance of holistic approaches to fisheries management, integrating ecological, socioeconomic, and conservation considerations. Such interdisciplinary efforts are paramount for safeguarding marine ecosystems and supporting the livelihoods of coastal communities worldwide.

“…Purse seine juga disebut sebagai pukat cincin, karena dilengkapi dengan cincin dan didalamnya terdapat tali cincin dan tali kerut. Melalui cincin-cincin yang telah terpasang tali kolor (Purse line) yang bila ditarik, bagian bawah jarring menjadi tertutup dan membuat bentuk jarring secara keseluruhan menyerupai mangkuk besar (Wijopriono, 1995).

Scads fish (Decapterus spp.) is a fish that is widely consumed by the community so that consumer demand in the market is high for Scads Fish. Based on the Statistics book from the KKP, the catch of Scadsfish has decreased in catches from 2014 to 2016, this is due to continuous catching. The purpose of this study was to estimate the sustainable potential and to determine the level of utilization of Scads Fish in Belawan Ocean Fishing Port, North Sumatra. The research data was obtained from the Belawan Ocean Fishery Port in February 2021. The method used in this study is a survey method, using an equation model, namely Schaefer. The data analysis is a simple linear regression analysis using SPSS version 20. The sustainable potential of Scads Fish (Decapterus spp.) in the last 5 years is 16,526 tons/year with a utilization rate of 67.98% which is included in the catch density category and the number of fish catches allowed is 13,221 tons/year

“…Indikator kelimpahan sumberdaya ikan siro (Amblygaster sirm) .... (Rudy Masuswo Purwoko) PENDAHULUAN Pemanfaatan ikan siro (Amblygaster sirm) telah dilakukan sejak lama di Laut Jawa khususnya dengan menggunakan pukat cincin mini. Beberapa kajian menunjukkan bahwa populasi ikan siro di Laut Jawa mengalami biological overfishing Atmaja, 2006;Atmaja & Nugroho, 2004;Wijopriono & Genisa, 2003). Beberapa peraturan diterbitkan untuk mengatasi hal tersebut, seperti Peraturan Menteri Kelautan dan Perikanan Nomor 3 tahun 2014 tentang rencana strategis kementerian kelautan dan perikanan tahun 2010 -2014 menyatakan bahwa produksi perikanan tangkap nasional adalah sebesar 5,44 juta ton di mana kenaikkannya kurang dari 8 % dari tahun sebelumnya.…”

ABSTRAKPemanfaatan ikan siro (Amblygaster sirm) di Laut Jawa menunjukkan gejala overfishing. Beberapa aksi pengelolaan telah dilakukan untuk mengatasinya dan efektifitasnya dipertanyakan. Penelitian ini bertujuan untuk memperbaharui status populasi ikan siro di Laut Jawa dengan menggunakan beberapa indikator, yakni kelimpahan dan biologi. Pengumpulan data dilakukan di Pelabuhan Perikanan Nusantara (PPN) Pekalongan selama 6 bulan (Oktober 2013 -Maret 2014). TropFishR package digunakan untuk menganalisis beberapa parameter pada 830 individu. Hasil penelitian menunjukkan ukuran panjang berkisar antara 14,1-24.5 cmFL. Parameter pertumbuhan ikan siro (Linf, K dan t 0 ) masing-masing sebesar 21.9 cmFL, 1,7/ tahun dan 0,45. Perbandingan antara jumlah kelamin jantan dan betina dalam kondisi seimbang. Pola pertumbuhan ikan siro bersifat alometrik negatif (2,259), dimana pertumbuhan panjang lebih cepat dari pertumbuhan beratnya. Ukuran panjang pertama kali matang gonad (Lm) dan ukuran panjang pertama kali tertangkap (Lc) masing-masing sebesar 16,8 cmFL dan 15,4 cmFL. Indikator kelimpahan menunjukkan kecenderungan penurunan. Selain itu, Lc lebih kecil dari Lm yang mengindikasikan terjadinya growth overfishing. KATA KUNCI: Indikator stok; ikan siro; Laut Jawa ABST RACTThe exploitation of spotted sardinella (Amblygaster sirm) in the Java Sea indicates overfishing phenomenon. Several management measures implemented to address that issue but the effectiveness is questionable. This research aims to update the population status of spotted sardinella in Java Sea using several indicators i.e. abundance and biological indicators. Data collection conducted in Archipelago Fishing Port (AFP) Pekalongan within 6 months (October 2013 -March 2014. TropFishR package used to analyzed several paramters for 830 individual. The result showed the length was 14,1-24.5 cmFL. Growth parameters (Linf, K and t 0 ) of spotted sardinella was 21.9 cmFL, 1.7/year and 0.45. The sex ratio was equal, while the growth pattern was negative allometric (2,259) that length growth was faster than weight. The length at first mature (Lm) and the length at first capture (Lc) were 16,8 cmFL and 15,4 cmFL respectively. The abundance indicated an decresed biomass. Moreover, Lc was lower than Lm indicates growth overfishing occurred.
