Abstract

Fishing activities are one of the main economic supports for coastal communities in Pangandaran, especially at the Cikidang Fish Landing Base (PPI Cikidang). Trammel nets are widely used, but the impact on the composition and diversity of the catch is not well understood. This study aims to analyze the dynamics of production, CPUE (Catch per Unit Effort) values, composition, and diversity of trammel net catches from 2019 to 2021. Secondary data from PPI Cikidang were analyzed descriptively and quantitatively, using trend graphs, frequency distribution, CPUE, and the Shannon-Wiener diversity index (H'). The results showed that production and fishing efforts fluctuated seasonally, peaking in mid- to late years. The highest CPUE value occurred in October 2020 at 39.19 kg/trip, while the lowest value was recorded in April 2021 at 14.17 kg/trip. The catch composition was dominated by shrimp, particularly Dogol Shrimp (Metapenaeus monoceros), which increased from 50.61% (2019) to 60.55% (2021). The diversity index showed a decline from 1.50 (2019) to 1.08 (2021), indicating the dominance of certain species and the potential decline in ecosystem stability. These findings highlight the importance of sustainable management of trammel net fishing gear to prevent negative impacts on marine biodiversity in the area

Abstract

Ikan pelagis hidup di lapisan tengah hingga permukaan laut dan bermigrasi dalam kelompok untuk mencari habitat optimal. Migrasi mereka dipengaruhi oleh parameter oseanografi seperti salinitas, arus laut, konsentrasi klorofil-a, dan suhu permukaan laut (SPL),. Penelitian ini bertujuan mengkaji hubungan antara parameter oseanografi dan kelimpahan ikan pelagis melalui studi literatur. Data oseanografi berbasis satelit, seperti MODIS, dapat memberikan informasi penting untuk memprediksi zona potensial penangkapan ikan. Hasil kajian menunjukkan bahwa SPL dan klorofil-a berperan penting dalam mendukung produktivitas perikanan. Konsentrasi klorofil-a tinggi mencerminkan produktivitas primer yang mendukung rantai makanan ikan pelagis. Selain itu, salinitas dan arus berkontribusi pada distribusi plankton sebagai sumber makanan utama. Pemahaman dinamika oseanografi membantu meningkatkan efisiensi penangkapan dan mendukung pengelolaan perikanan berkelanjutan. Penelitian ini diharapkan memberikan informasi bagi pemerintah dan nelayan dalam menentukan kebijakan dan strategi penangkapan yang lebih efektif.

Abstract

Cisanti Lake, the strategic zero point of the Citarum River, faces the threat of cadmium (Cd) pollution from surrounding agricultural activities. Conducted during the dry season of 2024, this pioneering study assesses the Cd pollution status using a multicompartment approach (water, sediment, and bioindicator organism Sinanodonta pacifica, Heude 1878). Samples from the three stations were analyzed using Atomic Absorption Spectrophotometry (AAS). The concentration of Cd in water was very low (0.0012–0.0030 mg/L), but it accumulated significantly in sediment (0.37–0.65 mg/kg) and mussel tissue (0.20–0.30 mg/kg). Although the concentration in water and biota was below quality standards, ecological risk analysis revealed that the sediment has moderate contamination (Contamination Factor: 1.25–2.15) and acts as a long-term pollutant sink. S. pacifica proved effective in accumulating Cd from the water column, demonstrated by a high Bioconcentration Factor from water to biota (BCF b-w >75), making it a reliable bioindicator of Cd pollution. This study provides crucial baseline data on environmental management in the upstream Citarum and establishes sediment monitoring as a vital early warning tool for future pollution risks.
