Abstract

Blue swimming crab (BSC) (Portunus pelagicus) is an Indonesian export commodity for America. The distribution of BSC can be found in the seas of Java, Madura, Sumatra, Bangka Belitung, Kalimantan and Sulawesi. Differences in BSC habitat conditions and climatic conditions in various Indonesian marine locations influence the distribution and abundance of BSC in each location. Information on the distribution and seasonality of BSC in Indonesian seas is still limited. Analysis of the distribution and season of BSC in Indonesian seas based on a study of catch numbers for 2022-2023 PT Kelola Mina Laut. The highest number of catches was in the Madura, West Java and East Java regions, with the lowest number of catches in the Sulawesi and Bangka Belitung regions. The highest total catch occurred in quarter 2 (April-June) and the lowest total catch occurred in quarter 3 (July-September). This research data can be a basis for developing and exploring the potential of BSC in several Indonesian marine locations, but further analysis needs to be carried out regarding other factors that can influence the distribution and season as well as the catch of BSC fishermen in Indonesian seas.

Abstract

The production of male catfish is faster, resulting in a shorter harvest period, which can increase profits for farmers. To produce superior male catfish fry, masculinization is conducted. Cow's Testicles Flour (CTF) is one of the natural alternative materials that can be used for the masculinization process in fish. This study aims to determine the best concentration of cow's testicles flour to enhance the success of masculinization in mutiara’s catfish (Clarias gariepinus) through immersion techniques. The method used is an experimental method consisting of 4 treatments with 4 replicates (0 mgL⁻¹, 45 mgL⁻¹, 60 mgL⁻¹, and 75 mgL⁻¹ CTF). The parameters observed were the percentage of male sex, survival rate, growth, and water quality. The highest percentage of male catfish was obtained at a concentration of 60 mgL⁻¹ CTF, at 72%. The highest absolute length and specific length growth rate were found at the 60 mgL⁻¹ CTF dosage, measuring 5.43 cm and a specific length growth rate of 3.05%. The highest absolute weight in catfish was found at the 75 mgL⁻¹ CTF dosage, at 4.69 g. The highest specific weight growth rate in catfish was observed in the control treatment, at 2.40%. The ideal water quality to support the survival of catfish includes a temperature range of 26.26-29.85°C; pH range of 6.5-8.3; and DO range of 4.6-6.7 mgL⁻¹.

Abstract

Cantang grouper is a hybridization between female tiger grouper and male kertang grouper. Transporting fish using a closed transportation system can cause stress, which results in increased blood glucose levels in fish as a secondary physiological response. This study aims to analyze blood glucose levels and identify bacteria in cantang grouper (Epinephelus fuscoguttatus lanceolatus) distributed from hatcheries in Bali. The results showed that the average blood glucose level reached 102 mg/dL, higher than the normal range (27–56 mg/dL), indicating that the fish experienced stress due to bacterial infection and the transportation process. The cantang grouper observed had been infected with Vibrio alginoliticus bacteria with the lowest TVC value of 98 x 105 CFU/mL and the highest 239 x 105 CFU /mL. The relationship between blood glucose and TVC values is positively correlated. The higher the blood glucose, the higher the TVC value in cantang grouper. Bacterial identification revealed the presence of Vibrio alginolyticus, a major pathogen causing vibriosis in marine fish. This study highlights the importance of improving transportation systems and implementing strict biosecurity to reduce stress and infection in cantang grouper

Abstract

One method to extend the shelf life of fish filets is through antibacterial preservation, which can be achieved using a cassava peel fermentation solution containing lactic acid bacteria that can combat spoilage bacteria in fish. This study aims to determine the effect of cassava peel fermentation solution on the organoleptic quality of red tilapia filets during low-temperature storage (5°-10°C). Red tilapia filets were soaked in a cassava peel fermentation solution with varying salt concentrations across four treatments: 0% (control), 2%, 3%, and 4%, with a soaking time of 30 minutes per filet according to the treatment. Observations were conducted on days 1, 4, 7, 8, 9, 10, 11, and 12, with organoleptic evaluations (appearance, aroma, slime, and texture) and data analysis using the Friedman statistical test, Multiple Comparison, and Bayes test. Results indicated that a 3% salt concentration yielded the best organoleptic value, especially on day 10, with aroma as the highest-ranked parameter according to the Bayes test (weight 0,44), followed by appearance (0,37), slime (0,10), and texture (0,08). Thus, cassava peel fermentation solution with a 3% salt concentration effectively extends the shelf life of red tilapia filets.

Abstract

The fermentation process has been known for a long time, this process basically occurs in a food. At the beginning of its appearance, the fermentation process is used by many western countries to create a food that has many flavors. In tilapia, there are carbohydrates, protein, fat, as well as a number of vitamins B3, B12, potassium, phosphorus, and selenium. For many people, besides being high in nutrition, and having a savory and sweet taste, fish sauce is also very easy to make and the cost to make it is quite cheap and doesn't take a long time. The aim of this study was to determine the effect of traditional salt concentration and the effect of fermentation time on the quality of fish sauce. The research method used was an experiment with Completely Randomized Design (CRD) as the experimental design. The treatments used were the addition of saline solution concentration and fermentation duration, each treatment was repeated 3 times. The independent variables in this study were the concentration of traditional salt used and the time of fermentation. The controlled variables in this study were Streptococcus lactis bacteria, pineapple fruit, temperature, pH and tilapia. The dependent variable measured was the quality of tilapia fish sauce using proximate analysis and NaCl test in percent (%). In this investigation, the optimal treatment was a 7-day fermentation with a 5% saline solution concentration (W3K1), with a protein content of 17.38%, water content of 68.66%, ash content of 8.12%, fat content of 10.85%, and 0% carbohydrate content

Abstract

The longtail tuna (Thunnus tonggol) is one of the highest-producing fishery commodities in the waters of West Sumatra. Its abundance is influenced by oceanographic conditions, particularly indicated by chlorophyll-a concentration as a marker of water productivity. This study aims to examine the distribution of chlorophyll-a in relation to the catch of longtail tuna (Thunnus tonggol) using Aqua MODIS imagery in the waters of West Sumatra. The method used in this research is observational, involving data collection on chlorophyll-a distribution and logbook records. Chlorophyll-a data was obtained from the Ocean Color website, and logbook data for 2018–2022 was sourced from the Bungus Oceanic Fisheries Port (PPS). The results show that chlorophyll-a distribution in the waters of West Sumatra fluctuated between 2018 and 2022, with an average range of 0.15 mg/m³ to 0.33 mg/m³. A simple linear regression analysis showed a significant F-value of 0.0045, which is smaller than α (0.05), indicating that the regression equation is valid. This suggests that the distribution of chlorophyll-a has a significant effect on the longtail tuna catch in the waters of West Sumatra. The average annual CPUE (Catch Per Unit Effort) of longtail tuna was 0.44 tons/trip, with an average catch over the 2018–2022 period of 18.38 tons and an average of 41 trips per year.
