Abstract

Capture fisheries are one of the most contributing sectors in producing fishery products.The fourfinger threadfin (Eleutheronema tetradactylum) is one of the key commodities in the capture fisheries sector of Pasuruan City. The catch yield of this species is influenced by the mesh size of the gillnet used. This study aimed to determine the effect of different mesh sizes on the catch yield of fourfinger threadfin and to identify the most effective mesh size. The research was conducted using an experimental fishing method with a Randomized Block Design (RBD) comprising three gillnet mesh size treatments: 1.75 inches, 2.5 inches, and 4 inches, with nine fishing trips. Data on catch weight and number were analyzed using a One-Way ANOVA followed by the Least Significant Difference (LSD) test. The ANOVA results showed an F-value of 10.083 with a significance level of 0.001 (p-value < 0.05), indicating a significant difference in the catch weight of fourfinger threadfin (Eleutheronema tetradactylum) among the mesh size treatments. This finding suggests that mesh size has a significant effect on catch weight, with the 2.5-inch mesh size being the most effective for catching fourfinger threadfin in the Madura Strait, as it produced the optimal catch weight compared to 1.75-inch and 4-inch mesh sizes.

Abstract

Bluru Kidul Village is an area located near the northeastern coast of Sidoarjo, where its geographical position provides significant benefits for the community. Consequently, the majority of residents work as fishermen and live side by side with the marine ecosystem. Due to the existence of Bluru Kidul Village, Sidoarjo City is often referred to as a fisheries or coastal city. The fish resources in these waters are dominated by small pelagic fish, large pelagic fish, and demersal fish. One of the most widely used fishing gears is the gill net. This study applied treatments with soaking durations of 2 hours, 3 hours, and 4 hours. The objectives of this research were to identify the composition of gill net catches, analyze the effect of different soaking times on gill net catches, and determine the optimal soaking duration for catching Indian mackerel (Rastrelliger) using gill nets. Data analysis was conducted using statistical methods, including analysis of variance (ANOVA) and normality tests to ensure data suitability. To determine whether soaking duration had a significant effect, a further statistical test, namely the Least Significant Difference (LSD) test, was applied to identify which soaking time produced the best catch of Indian mackerel. The results indicated that there were significant differences in catch variables between the 4-hour treatment and the 3-hour and 2-hour treatments, whereas the difference between the 3-hour and 2-hour treatments was not significant. This finding demonstrates that the 4-hour soaking duration resulted in significantly different catch outcomes compared to the 3-hour and 2-hour durations, but no significant difference was observed between the 3-hour and 2-hour treatments.

Abstract

The purpose of this study is to determine the effectiveness of using light sticks and without lights on catching ribbonfish from the number of catches. The method used in this study is an experimental fishing method with data analysis using the T test. This study was conducted in the waters of Pasongsongan Sumenep. The results of the ribbonfish catch during 16 trips with light sticks totaled 163 fish, while those without lights totaled 67 fish. The type of ribbonfish caught was dominated by the Trichiurus lepturus species. From the catch results, a T test analysis was carried out and the results of the Paired samples test showed a sig. value (2-tailed) of 0.000 <0.05, which means there is a significant difference in the number of catches in the use of light sticks and without lights placed on the fishing hook position. This is because ribbonfish have phototactic properties towards light, in addition to searching for food more dominantly using the sense of sight.

Abstract

Vaname shrimp (Litopenaeus vannamei) is one of the fastest-growing aquaculture commodities and has become a leading export product in Indonesia. The increasing market demand for vaname shrimp requires continuous efforts to improve production efficiency and shrimp performance. One approach to enhancing shrimp growth and survival is the application of probiotics in feed, which can improve digestive processes, nutrient absorption, and water quality. This study aimed to evaluate the effects of different doses of Seita microbiome probiotics added to pellet feed on the survival rate and growth performance of PL-10 vaname shrimp fry (Litopenaeus vannamei). The experiment was conducted using several probiotic dosage treatments, and the observed parameters included survival rate, weight gain, and water quality indicators. The results demonstrated that the application of Seita microbiome probiotics positively influenced shrimp growth and survival. Among the tested treatments, the probiotic dose of 30 mL/kg feed was found to be the most effective and optimal. This treatment produced the highest average survival rate of 90% and an average weight gain of 2.93 g. Furthermore, water quality remained within suitable ranges for shrimp culture, with temperatures of 28–29°C, dissolved oxygen levels of 6–7 ppm, pH values of 8.0–8.2, and salinity levels of 29–30 ppt. These findings indicate that Seita microbiome probiotics can be utilized as a beneficial feed additive to improve the productivity of vaname shrimp farming.

Abstract

Common carp (Cyprinus carpio) is one of the primary freshwater aquaculture commodities that plays a strategic role in supporting national fish production and contributing to the livelihoods and economic development of local communities. The high intensity of aquaculture practices, combined with the movement of live fish across regions, increases the risk of fish disease transmission, particularly highly contagious viral diseases. One of the most significant viral diseases of concern is Koi Herpes Virus (KHV), which can cause high mortality rates and substantial impacts on production, economic stability, and fish trade activities. This study aimed to detect the presence of Koi Herpes Virus (KHV) and to determine its prevalence in common carp (Cyprinus carpio) commodities transported through the Animal, Fish, and Plant Quarantine Center of North Sulawesi using the Real-Time Polymerase Chain Reaction (qPCR) method. The research employed a descriptive design with a surveillance approach. The study samples consisted of five common carp collected from quarantine traffic activities. Detection of KHV was conducted through DNA extraction followed by amplification of the viral target gene using the qPCR method. The prevalence rate was calculated based on the proportion of positive samples relative to the total number of examined samples. The results showed that out of five examined common carp samples, one sample tested positive for Koi Herpes Virus (KHV), while the remaining four samples were negative. Based on these findings, the prevalence rate of KHV in common carp transported through the Animal, Fish, and Plant Quarantine Center of North Sulawesi was 20%. These findings indicate that although the majority of transported fish were KHV-negative, the potential introduction and spread of the virus through fish movement remains present. In conclusion, the Real-Time PCR (qPCR) method is effective as an early detection tool for Koi Herpes Virus (KHV) due to its high sensitivity and specificity. The detection of KHV in a portion of transported common carp emphasizes the importance of strengthening fish quarantine surveillance and consistently implementing laboratory examinations as preventive measures against the spread of fish diseases to other regions, in accordance with the national fish quarantine system.
