Assessing Bali sardine stock status using real-time electronic catch landing data recorder and time series catch database

Abstract

Digitalization of capture fisheries data becomes inevitable in the present and future time. The use of Information and Communication Technology (ICT) in the fisheries sector is widely applied, creating a bigger and better database. Development of the database offers the utilization of Big Data and Decision Support System (DSS) to provide robust analysis, simulate better scenarios, formulate recommendations, and propose management measures to support successful fisheries management in achieving sustainability and profitability objectives. Bali Strait sardine stock estimation has been conducted several times through several approaches and techniques. This study will combine the available times series catch and effort data from published statistic landing data and publications with real-time data from electronic catch monitoring in Muncar and Pengambengan fishing port. The sardine stock and fishery status estimation were analyzed using a stock-production model incorporating covariates (ASPIC), a Nonequilibrium surplus-production model to data on fish catch and relative abundance. Another purpose of this study is to increase stakeholder participation through a smart dashboard system that enables automatic data analysis, faster recommendations socialization, and engagement. Increased stakeholder participation in fisheries management will be a crucial factor in achieving operational and successful fisheries management.

Keterkaitan Musim Hujan Dan Musim Angin Dengan Musim Penangkapan Ikan Lemuru Yang Berbasis Di PPN Pengambengan

“…Lemuru merupakan komoditas utama sumber daya ikan di perairan Selat Bali. Produksi lemuru mendominasi sekitar 85% dari total produksi ikan di Kabupaten Jembrana tahun 2020 (Natsir et al 2021). Ikan lemuru di wilayah ini umumnya ditangkap dengan alat tangkap utama yaitu purse seine dengan menggunakan dua kapal (Himelda et al 2012).…”

“…Produksi lemuru cenderung meningkat di saat El Nino (Merta & Nurhakim 2004;Puspasari et al 2021;Sambah et al 2021;Jatisworo et al 2021) dan mengalami menurun di saat La Nina (Purwanto 2012;Radiarta & Sidik 2020). Produksi lemuru turun drastis pada periode tahun 1980-1981, 1984-1985, 1992-1993, 2002-2003, 2010-2011(Nugraha et al 2018, dan terakhir 2017-2018 (Natsir et al 2021;Sambah et al 2021), bahkan pada periode September 2016 hingga Mei 2017 terjadi paceklik perikanan lemuru di Selat Bali (Nugraha et al 2018).…”

“…Adapun musim lemuru yang terjadi di bulan April sebagaimana juga tercatat oleh Rahadian et al (2019) dan Natsir et al (2021), diduga merupakan ikan lemuru dewasa. Wudianto & Wujdi (2014) menemukan ikan lemuru berukuran rata-rata di atas 16 cm di bulan April.…”

“…Fluktuasi hasil tangkapan lemuru telah terjadi pada periode-periode sebelumnya sejak 1980-2019 (Nugraha et al 2018;Natsir et al 2021). Fluktuasi tersebut dipengaruhi oleh faktor El Nino dan anti El Nino (La Nina) (Merta & Nurhakim 2004;Purwanto 2012;Radiarta & Sidik 2020;Puspasari et al 2021;Sambah et al 2021;Jatisworo et al 2021).…”

Northern Coast of java grouper fishery characteristics: an analysis of time series landing data

“…In 2013 Directorate general of capture fisheries (DGCF) established Fishing Port information Center nationally known as "Pusat Informasi Pelabuhan Perikanan (PIPP)" [7]; currently, 205 fishing ports are already prepared to connect to the system and 125 fishing ports were connected to the system and reported daily landing monitoring through a database system. The utilization of the database is under DGCF-Ministry for Marine Affairs and Fisheries (MMAF).…”
