Abstract

The purpose of this study is to determine the most effective setting time for collapsible crab traps in catching blue swimming crabs (Portunus pelagicus) in the waters of Tanjung Kait, as well as to assess whether the setting time affects the number of crabs caught across three different time periods. The research method used in this study is an experimental method. Experimental research fundamentally aims to test the relationship between cause and effect. This study employs a Randomized Block Design (RBD) with nine repetitions, using three different setting times: morning, noon, and night. The results of this study indicate no significant difference between the three setting times—morning, noon, and night. Although variations in the number of crabs caught at different times were observed, statistical analysis confirms that these differences are not significant. Therefore, blue swimming crab fishers in the waters of Tanjung Kait can use any of these three setting times to achieve effective catches.

Abstract

Tuna fisheries are a strategic sector in Indonesia's fishing industry, contributing significantly to the national economy. Albacore tuna (Thunnus alalunga) has high economic value and is one of the main commodities in international trade. This study aims to analyze the effect of different longline setting times on albacore tuna catches in the Seas of Benoa Harbor. The setting times compared were morning (08:00–10:00) and afternoon (14:00–16:00), focusing on the quantity and weight of the catch. The research method used was an experimental approach with two setting time treatments and nine replications for each treatment. Data obtained were analyzed using a T-test to determine significant differences between morning and afternoon catches. The results showed that the average catch in the morning was higher than in the afternoon, both in terms of individual count and fish weight. The average fish weight obtained in the morning was 63.78 kg, while in the afternoon, it was only 28.67 kg. Statistical analysis indicated a significant difference between morning and afternoon catches, with a T-Statistic value of 2.38, which exceeded the T-Critical value (2.12) at a 5% significance level (p-value = 0.0366). This suggests that the morning setting time is more optimal for catching albacore tuna than the afternoon setting. Catch variation was also greater in the morning, as indicated by a higher standard deviation compared to the afternoon. This difference may be attributed to the daily migration patterns of albacore tuna, which are more active in feeding during the morning, as well as environmental factors such as water temperature and light intensity. Based on these findings, this study recommends that fishers in the Seas of Benoa Harbor should set their longline fishing gear in the morning to maximize their catch.

Abstract

Purse seine fishing gear is a type of fishing equipment consisting primarily of a large net, designed to catch both large and small pelagic fish. This study aimed to (1) determine the effect of time differences—morning and evening—on the catch of flying fish using mini purse seine fishing gear, and (2) identify the composition and dominant species caught in each fishing period. The research was conducted at Banda Neira Pier, Banda District, Central Maluku Regency, Maluku, Indonesia. An experimental fishing method was applied, and data were analyzed using the Two Sample t-Test. Fishing operations were carried out over 16 trips, equally distributed between morning and evening sessions. The total recorded catch comprised 15,078 kg of mackerel (Rastrelliger sp.), 4,017 kg of skipjack (Katsuwonus pelamis), 18,743 kg of deho (Euthynnus affinis), and 45,601 kg of flying fish (Decapterus sp.). In the morning, the total catch reached 36,005 kg, dominated by flying fish, whereas in the evening, it was 50,250 kg, also dominated by flying fish. Statistical analysis using the Two Sample t-Test focused on the dominant species, flying fish, and revealed a p-value of <0.05. This indicates a significant difference in the composition of the catch between morning and evening fishing activities. The findings suggest that fishing time plays a crucial role in catch volume, particularly for flying fish, with evening fishing showing higher yields. These results can be valuable for optimizing fishing strategies, improving efficiency, and supporting sustainable fisheries management in Banda Neira and similar pelagic fishing grounds.

Abstract

This study aims to determine the effect of adding EM4 probiotics in various doses to commercial feed on the growth of jatimbulan tilapia (Oreochromis niloticus L). Probiotics are known to play a role in increasing digestive efficiency, nutrient absorption, and maintaining the health of the fish's digestive tract, so they are expected to support optimal growth. The research method used was a Completely Randomized Design (CRD) with four treatments, namely: P0 (control/without probiotics), P1 (5 ml EM4/kg feed), P2 (7 ml EM4/kg feed), and P3 (11 ml EM4/kg feed), each with four replications. The parameters observed were the growth in length and weight of jatimbulan tilapia during the maintenance period. The results showed that the administration of EM4 probiotics at certain doses was able to provide a significant effect on the growth of tilapia compared to the control treatment. Treatment P2 (7 ml/kg feed) provided the best growth results compared to other doses, both in terms of increasing length and body weight. Meanwhile, administering probiotic doses that are too low (P1) or too high (P3) tends to be less effective in supporting optimal growth. This is thought to be due to the disruption of the microbial balance in the digestive tract when the probiotic dosage is incorrect. This research provides useful information for Jatimbulan tilapia cultivation practices, particularly regarding the use of probiotics to increase growth efficiency. Using the correct probiotic dosage can be a strategy to increase the productivity and sustainability of freshwater fish farming.

Abstract

This study aimed to evaluate the effect of post-larvae (PL) 12 density of whiteleg shrimp (Litopenaeus vannamei) on survival during transportation using a closed wet system. The study was conducted experimentally using four different density treatments: 500, 750, 1000, and 1250 shrimp per liter of water. The purpose of these density variations was to identify the optimal density level that still ensured a high survival rate during transportation. The results showed that shrimp seed density significantly influenced survival. A density of 500 shrimp/liter resulted in the highest survival rate of 99.6%, while a density of 1250 shrimp/liter showed the lowest survival rate of 99.30%. Although the differences in numbers appear small, the ANOVA statistical test showed that the differences between the treatments were significant. These results were reinforced by a further LSD (Least Significant Difference) test, which confirmed significant differences between treatment groups. In addition, water quality parameters such as dissolved oxygen, temperature, and pH were also observed during transportation. Measurement results showed that dissolved oxygen and temperature changed significantly with increasing seed density. However, pH did not show any significant differences between treatments. Overall, the results of this study indicate that shrimp seed density and water quality parameters are important factors to consider in the shrimp fry transportation system. Appropriate density management can minimize stress and mortality, and ensure seed survival during the distribution process.

Abstract

This study aims to analyze the effect of water quality on the productivity of bamboo lobsters (Panulirus versicolor) cultivated in a floating net cage sistem (KJA) in the waters of Sinabang Bay, Simeulue Regency. Water quality is one of the main environmental factors that determines the success of marine cultivation, especially for high-value species such as bamboo lobsters. Water quality parameters observed in this study included temperature, salinity, pH, dissolved oxygen (DO), and ammonia levels. Measurements were carried out periodically during the 90-day cultivation period to capture environmental dynamics that affect the biological performance of lobsters. This study used a Completely Randomized Design (CRD) experimental design with three treatments based on different cultivation locations that have variations in natural water quality, each with three replications. The results showed that optimal water quality significantly affected the increase in bamboo lobster productivity, as indicated by the parameters of the specific growth rate (SGR), feed conversion efficiency (FCR), and survival rate (SR). The location with the best water quality (P1), which had high DO and low ammonia levels, recorded a daily SGR of 1.82%, a FCR of 1.6, and a SR of 90%. Conversely, the location with low water quality (P3) showed significantly decreased biological performance, with suboptimal SGR, FCR, and SR, primarily due to low dissolved oxygen and high levels of toxic ammonia. These findings emphasize the importance of continuous monitoring and management of water quality in marine cage sistems to support optimal lobster growth and survival. Therefore, managing aquatic environmental quality is key to increasing mariculture productivity and ensuring the sustainability of fishery resources in coastal areas.

Abstract

Plankton are microorganisms that have an important role in aquatic ecosystems, especially in fisheries cultivation activities. The presence of plankton functions as natural feed for aquatic organisms, thus affecting the growth and survival of aquaculture biota. However, in the rainy season the quality of pond water often changes, especially in pH parameters, which can disrupt the stability of aquatic ecosystems. One of the efforts made to maintain pH stability is with periodic liming techniques. This study aims to determine the biodiversity of plankton in the Bossbaster cultivation pond by applying periodic calcification techniques. The research was carried out on October 10–23, 2022 at the Bossbaster cultivation pond. The study focuses on aspects of abundance, diversity, uniformity, and dominance of plankton, both phytoplankton and zooplankton. The results showed that the average phytoplankton abundance in pond 1 was 41,002 cells/L, pond 2 was 40,853 cells/L, and pond 3 was 32,826 cells/L. Meanwhile, the average zooplankton abundance in pond 1 was 51 ind/L, pond 2 was 52 ind/L, and pond 3 was 66 ind/L. The average value of the phytoplankton diversity index ranged from 0.809–0.930,  Meanwhile, zooplankton ranges from 1.1863–1.4740. The phytoplankton uniformity index ranges from 0.4458–0.4814, while zooplankton reaches 0.880–0.881. The phytoplankton dominance index is in the range of 0.479–0.4809, and zooplankton is in the range of 0.2645–0.3514. These findings show that periodic liming techniques are able to maintain the stability of pond conditions so as to support the sustainability of plankton as an indicator of water quality. Thus, the application of this technique can be an important strategy in supporting the sustainability of aquaculture while improving the efficiency of pond management in a sustainable, innovative, and adaptive manner to changes in the increasingly complex aquatic environment.

Abstract

This study aims to analyze the effectiveness of gillnet mesh sizes (1 inch and 3 inches) on fish catches in the waters of Enggano Island, Bengkulu. The method used is a quantitative experiment by catching fish using gillnets with mesh sizes of 1 inch and 3 inches for three trips around the waters of Enggano Island. The data collected included the number, length, and weight of fish caught, which were then analyzed using an independent t-test. The results showed that the 1-inch mesh caught more fish than the 3-inch mesh, but the fish caught with the 3-inch mesh were larger in size and weight. Although there were differences in the number and weight of fish caught, the results of statistical tests showed that the differences were not statistically significant, so that both mesh sizes had comparable effectiveness in the context of fishing at the study site. The conclusion of this study shows that the use of a 3-inch mesh is more recommended for getting fish with higher economic value, while a 1-inch mesh is more effective for catching more fish. Further research is recommended to examine other mesh size variations and their impacts on the sustainability of fish resources

Abstract

Panggungrejo District in Pasuruan City is a central hub for fishing activities with significant potential for capture fisheries production. One of the fishing gears used by fishermen in this area is the boat dredge, which is classified as an active fishing gear. This study aims to assess the environmental friendliness of the boat dredge used by fishermen in Panggungrejo based on the principles of the Code of Conduct for Responsible Fisheries (CCRF). The research employs a descriptive method, using data collection techniques such as interviews with structured questionnaires, direct observations, document analysis, and literature review. The study involved 32 respondents consisting of fishermen using the boat dredge. Data analysis was performed by assigning scores based on the principles outlined in the CCRF that are related to sustainability and environmental impact of the fishing gear. The results showed that the boat dredge in Panggungrejo scored a total of 855, with an environmental friendliness score of 26.71. Based on this score, the boat dredge falls into category III, considered “environmentally friendly.” However, several indicators related to resource efficiency and the impact on aquatic ecosystems still need improvement to further enhance the environmental friendliness of this fishing gear. This study provides recommendations for the development and improvement of more environmentally friendly fishing techniques and increasing fishermen’s awareness of sustainability in fisheries practices.
