Abstract

Polyculture is a system wherein diverse organisms cohabit to mutually sustain one another. Green mussels (Perna viridis) are filter feeders that enhance water quality and facilitate the proliferation of other creatures. This study looks at how the number of green mussels affects the Total Organic Matter (TOM) content, cell count, cell features, and the absolute weight growth of Gracilaria verrucosa in a polyculture system in the pond at Pangkahkulon village. We evaluated three density treatments of green mussels (10, 20, and 30 individuals/m2) over a duration of 21 days. TOn the first day, the results showed a variation in TOM concentrations from 86.71 to 86.91 mg/L across all treatments; however, by day 21, there was a notable decline, with the 30 individuals/m2 treatment dropping to 33.18 mg/L. he cell count of Gracilaria verrucosa fluctuated, with the 30 individuals/m2 density treatment yielding the maximum count of 82 cells, followed by the 20 individuals/m2 treatment. Analysis of Variance (ANOVA) and Tukey's post hoc test showed that green mussel density had a big effect on the seaweed's absolute weight growth, even though there were no significant changes in cell count. These findings indicate that green mussels can enhance water quality and facilitate the proliferation of seaweed in polyculture systems.

Abstract

This study aims to analyze the species composition and economic value of fish catches at the Nusantara Fisheries Port (PPN) Brondong in 2024. Using a descriptive-quantitative approach based on primary data, monthly data were collected on species type, catch volume, and market price over the course of one year. The results show that 35 fish species were recorded, with Swanggi, Kurisi, and Biji Nangka dominating in terms of volume, while squid contributed the highest economic value due to its high market price. On the other hand, Lemuru, Kembung, and Bawal Hitam had the lowest catch volumes and economic contributions. A discrepancy was found between catch volume and economic value, highlighting the potential for fisheries management to focus on high-value species that are currently underexploited, such as Red Snapper and Spanish Mackerel. This study emphasizes the importance of sustainable fisheries management by integrating ecological and economic considerations to ensure the long-term sustainability of marine resources and the welfare of fishing communities.

Abstract

Fish caught on board must be processed carefully to ensure their quality meets desired standards. Proper handling of the catch is a crucial factor affecting the freshness and quality of fish. Conversely, poor handling may result in low catch quality. This study aims to analyze the suitability of handling and storage techniques using the bulking method, catch composition, and the compliance level of fishermen in handling fish catches on board, based on Minister of Marine Affairs and Fisheries Regulation No. 7 Article 6 of 2019, in the Central Java Sea. Data were collected throught direct observation on the KM Sinar Mandiri purse seine vessel and analyzed descriptively. The catch composition on KM Sinar Mandiri consisted mainly of Decapterus sp. 49%, followed by Euthynnus affinis 41%, Parastromateus niger 6%, and Loligo sp 4%. Observations showed that handling practies on KM Sinar Mandiri did not fully comly with Permen KP No. 7/2019 Article 6. Deficiencies included the absence of a special storage area for chemicals, cleaning and packaging materials, the use of ice not meeting hygine standars, and no pest identification program. As a result, the compliance level in handling fish catches was only 57%.
