Abstract

The Baronang fish (Siganus guttatus) is an economically valuable species commonly found in seagrass ecosystems, which serve as critical habitats providing food, spawning, and nursery grounds. This study, conducted from June to August 2024, aimed to examine the length-weight relationship, growth patterns, and the influence of environmental parameters on Baronang fish growth. Fish samples were collected using beach seines of various mesh sizes. The length-weight relationship in June followed the model W = 0.12L².19 (R² = 0.72), in July W = 1.07L⁰.34 (R² = 0.99), and in August W = 2.72L⁰.674 (R² = 0.94), indicating varying degrees of correlation across months. Growth analysis using the von Bertalanffy model showed an asymptotic length (L∞) of 154.00 mm and a growth coefficient (K) of 0.51/year. In August, the estimated L∞ was 19.95 cm, K = 1.01/year, and t₀ = 0.176. The fish reached a length of 88.97 mm in the first year and 150.95 mm by the sixth year, with growth slowing down after this period. Environmental parameter analysis revealed that temperature had a significant positive effect on fish weight (B = 14.664, p < 0.001), while salinity (B = -5.920, p = 0.005) and dissolved oxygen (DO) (B = -28.357, p = 0.001) had significant negative effects. These findings highlight the importance of environmental conditions in regulating the growth of Siganus guttatus in seagrass ecosystems.

Abstract

Land clearing for mining operations can potentially cause severe damage to coastal and marine environments. Restoration of post-mining areas can be addressed through closure and recovery efforts, particularly via coral reef rehabilitation. This study aims to determine site suitability for coral reef rehabilitation or marine reclamation in the waters of Tanjung Siangau. Conducted in August 2023, the study used a multi-parameter map overlay method to produce a suitability map for reef rehabilitation. Parameters considered include bathymetry, turbidity, current velocity, wave conditions, substrate type, reef exposure, protection status, proximity to coral donor sources, community involvement, and marine spatial zoning. Findings indicate that areas damaged by coastal and marine activities require reclamation, including coral rehabilitation. Reclamation of post-mining lands must adhere to Indonesian Law No. 3 of 2020 and the Mineral and Energy Resource Ministerial Regulation No. 26 of 2018. Overlay results revealed the highest suitability score in the southern waters of Tanjung Siangau, an area categorized as moderately damaged coral cover (<50%). Local community reports indicate that this area is not mined due to the absence of tin deposits. The recommended site for coral reef rehabilitation lies outside of any licensed mining concession and is situated within an Underwater Tourism Zone in accordance with the Coastal and Small Islands Zoning Plan (RZWP3K).

Abstract

Spanish mackerel (Scomberomorus spp.) is a pelagic fishery commodity with high economic value that is widely utilized in the Bangka Belitung Islands Province. High fishing activity has the potential to put pressure on the sustainability of fish resources if not balanced with proper management. Therefore, this study aims to analyze Spanish mackerel (Scomberomorus spp.) production, assess the utilization status of large pelagic fish resources, and describe fisheries management conditions in Bangka Belitung Islands Province. This study was conducted from April to May 2025 in Bangka Belitung Islands Province using secondary data obtained from the Statistics Data Portal of the Ministry of Marine Affairs and Fisheries and other relevant scientific publications. The research method used is a literature study and secondary data analysis obtained from the Ministry of Maritime Affairs and Fisheries Statistics Data Portal and various related scientific journals. Data were analyzed descriptively to determine the development of mackerel production and the condition of large pelagic fish resource utilization in the study area. The results show that mackerel production fluctuated with an increasing trend during the 2020–2024 period. The highest production occurred in 2024 at 17,149.72 tons, while the lowest production occurred in 2020 at 9,964.02 tons. Based on Ministerial Decree MMAF No. 19 of 2022, the utilization rate of large pelagic fish in the Indonesian Fisheries Management Area (IFMA) 711 is classified as fully exploited, with a utilization rate of 0.7. This condition indicates that intensive utilization of fish resources requires sustainable management through controlling fishing activities, monitoring fishing gear, and implementing measured fishing policies to maintain the sustainability of fish resources in the Bangka Belitung Islands Province.

Abstract

This study aimed to analyze the production trends and production value of mackerel tuna landed at Nusantara Fishing Port of Brondong (NFP Brondong), Lamongan Regency, East Java, within Indonesian Fisheries Management Area (IFMA) 712. The research was conducted from April to May 2025 using a quantitative descriptive approach based on time-series data from 2020 to 2024 obtained from the Statistical Data Portal of the Ministry of Marine Affairs and Fisheries of Indonesia. The results showed that mackerel tuna production exhibited a fluctuating pattern throughout the study period. The highest production was recorded in 2024 at 53.18 tons, while the lowest production occurred in 2022 at 18.37 tons, with an average annual production of 35.29 tons. The production value also fluctuated, reaching its highest level in 2023 at IDR 1,098,435,000 and its lowest level in 2024 at IDR 464,758,000. Fluctuations in production volume were likely influenced by fishing seasons, weather conditions, fishing activities, and oceanographic factors in the Java Sea. Meanwhile, fluctuations in production value were associated with market prices, consumer demand, and fish quality. The findings indicate that mackerel tuna remains an important fishery commodity in IFMA 712. Therefore, sustainable fisheries management is necessary through continuous production monitoring and appropriate control of fishing efforts to ensure resource sustainability and support fishers’ welfare.

Abstract

Lobster is a high-value fishery commodity in the southern coastal waters of West Java, which are included in WPPNRI 573. Increasing market demand has led to higher lobster fishing activities, potentially threatening the sustainability of lobster resources. This study aims to analyze lobster production in West Java from 2019–2024, identify the dominant lobster species, examine the factors influencing lobster exploitation, formulate sustainable lobster management strategies, and analyze government efforts to support sustainable lobster resource management in WPPNRI 573. The study was conducted from April to May 2025 using data obtained from the Ministry of Marine Affairs and Fisheries. A literature review method with a qualitative descriptive approach was employed, drawing on lobster production data and relevant scientific literature to analyze trends and related issues in lobster fisheries. The results showed that lobster production in West Java fluctuated, with the highest production recorded in 2020 at 167.36 tons and the lowest in 2023 at 24.42 tons. The dominant lobster species found were sand lobster (Panulirus homarus), pearl lobster (Panulirus ornatus), and bamboo lobster (Panulirus versicolor). The high fishing activity has caused lobster utilization to reach a fully exploited status, requiring sustainable management through minimum catch size regulations, fishing effort control, stock monitoring, the use of environmentally friendly fishing gear, supervision of illegal fishing, and lobster aquaculture development to ensure the sustainability of lobster resources.
