Abstract

This study aims to determine suitable biomarkers as monitoring tools for detecting heavy metal pollution in the Maros River. The analysis results showed that the livers of Corbicula javanica from the Maros River contained metallothionein Pb and metallothionein Cd. The average accumulation values of Pb and Cd that induced the appearance of metallothionein Pb were 0.001628 ppm and 0.004929 ppm, respectively. This study demonstrates that Corbicula javanica clams exhibit a significant biological response to exposure to heavy metals Pb and Cd in the Maros River, as evidenced by high bioaccumulation levels, the presence of the molecular biomarker metallothionein, and disturbances in physiological parameters such as the Gonad Somatic Index (GSI). Cd exhibited higher and faster accumulation patterns and Bioaccumulation Factor (BCF) values compared to Pb, indicating stronger toxicity potential and biological retention. The expression of Cd and Pb metallothionein in liver tissue, which appeared in the first and fifth weeks of exposure, demonstrated the high sensitivity of these biomarkers as early detection tools for heavy metal contamination. Conversely, although the GSI values of river freshwater clam were significantly lower than those of the control group, this parameter proved less sensitive to specific metal types, making it unsuitable as a sole indicator for early detection of contamination. The positive correlation between metal concentrations in tissues and shifts in physiological distribution, as determined by Principal Component Analysis (PCA), further supports the finding that freshwater clams experience stress accumulation over time. Based on the results obtained, Pb metallothionein and Cd metallothionein are biological markers (biomarkers) that can be used as tools for early detection of water pollution.

Abstract

Shrimp farming has rapidly grown into a significant sector worldwide, providing economic benefits and high-quality food. Probiotics are widely used in shrimp farming to enhance growth and prevent diseases. However, reports on the field-scale application of multispecies probiotics in shrimp farming are minimal. This study aims to evaluate the effectiveness of multispecies probiotics on the health status, production performance, and water quality of L. vannamei shrimp farming at a field scale. L. vannamei post-larvae were reared in maintenance ponds. The shrimp seeds were stocked in 10 plots (50×50×2 m²) and acclimated for 7 days. Multispecies probiotics were administered after acclimatization, and health status parameters, production performance, and water quality were subsequently measured. The results indicated that multispecies probiotics combined with molasses and fermented bran were ineffective at preventing V. parahaemolyticus growth, as evidenced by the health status of L. vannamei. However, multispecies probiotics improved production performance and water quality through the end of the maintenance period. This study highlights the effectiveness of multispecies probiotics in enhancing production performance and water quality. Further research is needed to understand the mechanism of action of these probiotics in vannamei shrimp at a field scale.

Abstract

Mangrove ecosystems play an important role in supporting the productivity of coastal capture fisheries by providing habitats, spawning grounds, and nursery areas for various fish species, as well as by facilitating ecological connectivity with adjacent coastal waters. This study aims to evaluate changes in mangrove cover in South Lampung Regency during 2020-2023, examine the variability of capture-fisheries production, and analyze the statistical relationships among these variables. The methods employed include multitemporal spatial analysis of Landsat 8 imagery using supervised classification and NDVI calculations, combined with statistical analyses based on Pearson correlation and simple linear regression, using fisheries production data obtained from the Department of Marine and Fisheries. The results indicate that mangrove cover increased from 475.5 ha in 2020 to 551.9 ha in 2023, in line with rehabilitation programs implemented in several coastal districts. During the same period, capture fisheries production reached 125,168 tons, dominated by squid, scads, yellowtail scads, anchovies, groupers, swimming crabs, and white shrimp. Statistical analysis revealed a powerful relationship between mangrove expansion and the catches of several key fisheries commodities. These findings are consistent with previous studies highlighting the importance of mangrove ecosystems for fisheries productivity and emphasize the role of mangrove conservation in supporting sustainable capture fisheries and coastal management in South Lampung Regency.

Abstract

The protein content of cassava crackers can be increased by adding minced mackerel. This research aims to determine the optimal percentage of mackerel fish mince to be added to the production of cassava crackers that yields the most preferred product, and to determine the proximate composition of the most preferred product. The method used was experimental: the production of cassava crackers with different levels of mackerel mince addition, comprising four treatments (0%; 7.5%; 10%; and 12.5%), with 20 semi-trained panellists as replicates, to determine the panellists’ preference for cassava crackers. The parameters observed in this study were the level of preference (hedonic) test, which was analysed using non-parametric statistics with the Friedman test, followed by multiple comparison tests and Bayes tests for decision making, as well as proximate tests to determine the moisture content, ash content, fat content, protein content, carbohydrate content, and calcium content. The results showed that cassava crackers with 10% mackerel meat added were the most preferred based on the Bayes method analysis and preference levels with average scores of 8.3 for appearance, 8.3 for aroma, 8.6 for taste, and 8 for texture. The proximate test results were moisture content 4.12%, ash content 3.41%, fat content 25.53%, protein content 4.51%, and carbohydrate content 72.26%, with an expandability of 59.22%.

Abstract

Hybridization is the process of crossing individuals with different genotypes to produce offspring with superior traits. In this study, Sangkuriang catfish were crossed with introduced Thai catfish to obtain heterosis in hybrid seeds. The objective was to analyze the genetic diversity of these hybrid seeds using the PCR-RAPD method. Specifically, the primers OPA-13, OPB-08, OPC-19, and OPD-02 were used. Crossbreeding involved Sangkuriang female and Thai male broodstock, with four pairs of broodfish used via a semi-natural spawning method. After spawning, hybrid seeds from each pair were reared separately in containers under uniform conditions for 1.5 months. DNA samples were then collected from the fin tissue of each replicate of the crosses, and were grouped according to size categories: large (7-8 cm), medium (5-6 cm), small (3-4 cm), and broodstock, with 30 samples per size category for each replicate. The results revealed a polymorphism percentage of 72.95-93.88%, heterozygosity values of 0.167-0.232, and an average genetic distance among hybrid seeds from the three size categories and broodstock ranging from 0.001-0.018.
