Abstract

Feed is a primary factor influencing the growth and survival of pearl catfish larvae, therefore innovation in alternative feed that is efficient and highly nutritious is required. This study aims to analyze the effect of feeding paste made from golden snail flour (Pomacea canaliculata) at different percentages on the growth and survival of African catfish larvae (Clarias gariepinus). The method used was an experimental design with a Completely Randomized Design (CRD), consisting of three feeding treatments (5%, 10%, and 15% of biomass weight) with five replications, conducted over a 30-day rearing period. The observed parameters included survival rate (SR), absolute weight growth, absolute length growth, average daily growth (ADG), specific growth rate (SGR), and water quality. Data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that different feeding percentages had a highly significant effect (p > 0.05) on all parameters. The best treatment was obtained at a feeding rate of 10% of biomass weight, with a survival rate of 96.4%, absolute weight gain of 24.6 g, absolute length gain of 4.56 cm, ADG of 0.41 g/day, and SGR of 70%. Water quality during the study remained within optimal ranges, with temperatures of 24–27°C and pH levels of 7.8–8.5. Thus, feeding paste made from golden apple snail flour at 10% of biomass weight is the optimal dosage to improve the growth and survival of pearl catfish larvae.

Abstract

Pangandaran's abundant fishery resources require proper processing to prevent rapid spoilage, making preservation through jambal roti salted fish production crucial for both food security and local livelihoods. Jambal roti salted fish production has become a crucial economic activity for coastal communities in Pangandaran. This study aims to analyze the processing performance and economic feasibility of jambal roti salted fish production in Pangandaran, West Java. The study employed Good Manufacturing Practices (GMP), Sanitation Standard Operating Procedures (SSOP), and Hazard Analysis and Critical Control Point (HACCP) for processing performance analysis, while Cost-Benefit Analysis (CBA) was used for economic feasibility assessment. The results showed that the enterprise is economically viable, with a monthly profit of IDR 4.940.278 and a profitability rate of 15.44%. Additional economic indicators include a BCR of 1.18, payback period of 0.23 years, BEP (Q) of 54.19 kg/month, BEP (IDR) of IDR 4.142.927/month, and a production cost per unit of IDR 67.649/kg. However, the technical performance evaluation indicated only 47% compliance with GMP, SSOP, and HACCP standards, suggesting substantial room for improvement in food safety practices. In conclusion, while jambal roti production in Pangandaran is economically feasible, improvements in processing performance are necessary to ensure better food safety compliance and sustainability.

Abstract

This study aimed to determine the growth performance of gourami fish (Osphronemus gouramy) fed with Daphnia sp. enriched with Viterna at different doses. The research used an experimental method with four treatments and three replications. The treatments consisted of P1 (0 ml/L as control), P2 (10 ml/L), P3 (20 ml/L), and P4 (30 ml/L) of Viterna enrichment. Data were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test to determine significant differences among treatments. The results showed that Viterna enrichment significantly affected absolute length growth, absolute weight growth, and daily growth rate (P<0.05), but had no significant effect on survival rate (P>0.05). The highest absolute length growth was observed in P4 (1.79 cm), which was not significantly different from P3 (1.39 cm), while the lowest was found in P1 (0.35 cm). The highest absolute weight growth was also found in P4 (1.91 g), which was not significantly different from P3 (1.64 g), while the lowest was in P1 (0.69 g). The highest daily growth rate was recorded in P4 (3.20%), which was not significantly different from P3 (3.13%), while the lowest was in P1 (2.46%). Based on the results, the enrichment of Daphnia sp. with Viterna at a dose of 20 ml/L (P3) is considered the most effective treatment for improving the growth of gourami fish.

Abstract

Small-scale fisheries in Bunyu Island, North Kalimantan, hold a strategic position in supporting Indonesia’s maritime border economy. Various stakeholders are involved in the management of small-scale fisheries in the island. The objective of this study is to analyze stakeholders engaged in small-scale fisheries in Bunyu Island, North Kalimantan, Indonesia. A survey method was employed, with data collection conducted from July to August 2025. Respondents were determined using a purposive sampling technique, comprising parties directly involved in small-scale fisheries on the island. The analysis employed stakeholder categorization, stakeholder analysis by influence-interest matrix, and actor linkage mapping to examine stakeholder positions and interactions. The findings indicate that 14 stakeholders are engaged in the management of fisheries in Bunyu Island. The Marine and Fisheries Office of North Kalimantan hold both high interest and influence due to its authority in fisheries management. Fishers, while having high interest, exhibit relatively low influence in the policy-making process. These findings highlight the presence of power asymmetry and predominantly top-down governance structure. Academic institutions play a role by providing research and recommendations to support fisheries management. To promote collaborative governance, the Provincial Marine and Fisheries Office should institutionalize fisher participation in decision-making forums.

Abstract

Indonesia is one of the world's major exporters of frozen shrimp, but its market share in China is still relatively small despite the country's high demand. This study aims to analyze the trend of Indonesia's frozen shrimp export performance to China, analyze comparative competitiveness using Revealed Comparative Advantage (RCA) analysis, analyze competitiveness dynamics through Export Product Dynamic (EPD), and formulate strategies to improve export competitiveness. The study used secondary time series data (2014-2023) obtained from BPS, KKP, UN Comtrade, and other official sources. The results showed that the trend of Indonesia's frozen shrimp exports to China fluctuates but tends to increase, with a significant spike in 2022. The RCA analysis shows that Indonesia's comparative competitiveness was strong at the beginning of the period, but weakened since 2019-2023 as the RCA value is consistently below one. Meanwhile, the EPD analysis shows that Indonesia's export position is often in the Lost Opportunities category, signaling a failure to capitalize on market growth despite growing Chinese demand. These findings indicate the need for strategies to strengthen competitiveness through market diversification, modernization of cultivation systems, improved logistics efficiency, implementation of international standards, and more aggressive promotion and branding in the Chinese market.

Abstract

Food security and malnutrition remain global challenges, requiring sustainable food production strategies such as the Blue Transformation concept promoted by FAO. African catfish (Clarias gariepinus) is an important aquaculture commodity for fulfilling nutritional needs, containing 19.03% protein, 8.1% fat, and high levels of essential amino acids. However, intensive farming systems often encounter constraints such as high feed conversion, reduced water quality, and suboptimal growth performance. Synbiotics, combining probiotics and natural prebiotics, offer a promising alternative to antibiotic use in aquaculture. In this context, the utilization of locally available banana peel waste as a prebiotic represents an eco-friendly approach that supports resource efficiency within the Blue Transformation framework. This study aimed to evaluate the effect of dietary synbiotics consisting of Lactobacillus casei and banana peel–based prebiotics on the growth performance and feed efficiency of African catfish. Four treatments were applied: a control diet (without synbiotics) and diets supplemented with 1%, 2%, and 3% (v/w) fermented banana peel prebiotics. Observed parameters included Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), feed efficiency, and survival rate. The results indicated that synbiotic supplementation positively influenced growth and feed utilization. The best performance was obtained at the 3% dose, with an SGR of 6.78%, FCR of 1.07, feed efficiency of 93,97%, and survival rate of 84%. These findings suggest that the application of synbiotics at an optimal dose can be practically implemented in intensive African catfish culture to reduce feed costs, improve production efficiency, and support more sustainable aquaculture practices

Abstract

Lobster (Panulirus homarus) aquaculture in Indonesia remains limited due to suboptimal feed management and culture systems, resulting in low growth and survival rates. This study aimed to evaluate the effects of different feed types and culture systems on growth performance, survival rate, feed efficiency, amino acid content, and carbonic anhydrase enzyme activity in lobster puerulus. The study was conducted using a factorial randomized block design with two factors: culture media (bottom cage, floating cage, and fiber tank) and feed types (kijing clams, trash fish, and shrimp head waste). Each treatment was replicated three times at a stocking density of 30 individuals per square meter. The results showed that the highest survival rate (90%) and best feed conversion ratio (6.6) were obtained in fiber tanks with kijing clam feed. The highest growth performance (5.11 g) and enzyme activity were recorded in fiber tanks with shrimp head waste feed. Amino acid content, particularly leucine, was also highest under the same treatment. Statistical analysis indicated that both feed type and culture system significantly influenced lobster performance, with strong relationships observed between feed composition and physiological responses. The conclusion is that the combination of appropriate feed and a controlled culture system is essential for improving lobster aquaculture performance. Fiber-based systems with high-quality feed provide optimal conditions for growth, survival, and metabolic activity, supporting more efficient and sustainable lobster farming.

Abstract

Efforts to increase milkfish production through efficient resource use are very important to study to provide alternatives for farmers in managing a milkfish pond business. It aims to increase production by using existing inputs so as to reduce farming costs and increase farmers' income. Specifically, the objectives of this study are (1) to describe the performance of the milkfish pond cultivation in both traditional and semi-technical production technologies, (2) to analyze the technical efficiency of the milkfish pond cultivation on both production technologies, and (3) identify the factors which affects the technical efficiency of the milkfish pond cultivation. This study used 2013 Agricultural Census data with a total of 1015 respondents of milkfish farmers in West Java Province. Data analysis was performed using descriptive and quantitative analysis. Descriptive statistical analysis was used to describe the characteristics of the respondents' activity, the socio-economic conditions of farmers, the use of production inputs from the milkfish pond cultivation. Quantitative analysis is used to analyze technical efficiency using the Data Envelopment Analysis (DEA) approach and to identify socio-economic factors that affect technical efficiency using the Tobit regression. The results showed that the milkfish pond cultivation in West Java Province in general is still cultivated traditionally (56 percent). The results also showed that the technical efficiency value of milkfish farmers with efficient traditional technology was 38 percent of the total farmers who cultivated traditionally with an average technical efficiency value of 0.7, while the milkfish farmers using semi-intensive technology were 22 percent of the 449 farmers. which uses semi-intensive technology with an average technical efficiency value of 0.6. The observed inefficiency may be attributable to suboptimal input allocation, although further analysis is required to establish a causal relationship.

Abstract

Nilem fish (Osteochilus hasselti) is a freshwater fish commodity with enormous potential for the aquaculture sector. In aquaculture activities, fish hatchery is one of the crucial aspects. To date, the performance of nilem fish hatchery activities at the UPT LKIL has not been reported. This study was conducted to understand techniques for hatching Nilem fish using a semi-artificial system at the UPT LKIL Pasuruan, East Java. This study was conducted over 60 days at the UPT LKIL Pasuruan, East Java (Figure 1). The method used during this study was descriptive. The results showed that the hatchery activity at UPT LKIL Pasuruan, East Java showed 94% fertilized eggs, a 91% hatch rate, and an 88% survival rate. It can be concluded that the hatchery of Nilem fish at UPT LKIL Pasuruan showed good performance. These great results were supported by the use of ovaprim, good dissolved oxygen content, and fine protein feed. Although the temperature and pH were higher, UPT LKIL conducted water changes to neutralize them. UPT LKIL should prepare an indoor pond to prevent sunlight penetration so that the temperature and pH are not high.
