Abstract

The barramundi, also known as Asian sea bass, has the ability to adapt to various environmental conditions. Indonesia has introduced barramundi from different regions, including Australia, which is known to have a faster growth rate and larger body size. At the same time, the Indonesian strain demonstrates greater resilience to local conditions but grows more slowly. This study evaluates the hatchery performance of Australian and Indonesian strains of barramundi (Lates calcarifer) in a controlled environment using circular concrete ponds. The research examines water quality, spawning productivity, and larval development. The results indicate that the Australian strain produces more eggs than the Indonesian strain, with a hatching rate of 62%. Key water quality parameters, including temperature (28.3–28.6°C), pH (8.26–8.29), and salinity (33–35 ppt), were generally favorable for successful spawning and larval development. Additionally, providing live feed, such as rotifers and Artemia, improved larval growth up to the early juvenile stage. The significant differences in productivity between the two strains highlight the importance of genetic selection and nutritional management in optimizing barramundi hatchery production. This study underscores the need for superior strain selection and the application of science-based aquaculture strategies to enhance the sustainability of barramundi production in Indonesia.

Abstract

Efforts to combat disease in farmed fish are typically done using antibiotics. However, long-term use of antibiotics can lead to disease resistance and environmental pollution. One herbal extract with potential as an immunostimulant is the soursop plant (Annona muricata L.). This study aims to understand the hematology of tilapia (Oreochromis niloticus) that were fed a diet mixed with soursop leaf extract (Annona muricata L.). The study design included four treatments and three repetitions, comprising treatment A (control), treatment B (2.5 g/kg feed), treatment C (5 g/kg feed), and treatment D (7.5 g/kg feed). The results showed that feeding a diet mixed with soursop leaf extract at a concentration of 7.5 g/kg feed (treatment D) could influence the increase in hematocrit levels by 26.11%, hemoglobin levels by 7.11 g/dl, and total leukocytes by 4.41 x 104 cells/mm3, but did not affect the total erythrocytes of tilapia.

Abstract

Aquaculture plays a vital role in meeting the global demand for animal protein, yet the dependency on expensive imported feed ingredients remains a significant challenge. Optimizing the use of local feed ingredients is a strategic approach to enhance sustainability and cost-efficiency in fish farming. This research aims to optimize the composition of local feed ingredients to achieve 30% protein content in farmed fish feed. The formulation involves rice bran, corn bran, fish meal, and tofu dregs, selected based on local availability and protein content. The methodology includes analysis of the protein content of raw materials, formulation testing, and physical evaluation of feed. The results show that the pellets produced have nutritional quality that meets the target, good physical stability, and cost efficiency of up to 40% compared to commercial feed. This research makes a significant contribution in supporting the sustainability of the fish farming industry and reducing dependence on imported raw materials.

Abstract

Tilapia (Oreochromis niloticus) is one of the most cultivated freshwater fish. The problem that is often faced in fish farming is diseases caused by parasitic attacks (ectoparasites) which can cause a decrease in fish production levels. To overcome these problems, research is needed on the intensity and prevalence of ectoparasites in tilapia (Oreochromis niloticus) to determine the density of ectoparasite attacks and the percentage of ectoparasites in tilapia. Tilapia (Oreochromis niloticus) samples were taken from the Floating Net Cage (KJA) of Lake Batur, Songan Village, Kedisan and Trunyan. Sampling is carried out by purposive sampling or determining location points. The tilapia (Oreochromis niloticus) samples examined were 36 fish samples with a size of 14.7-21 cm tilapia niwana. The ectoparasite found only in the gills of tilapia, namely Dactylogyrus sp. (506 ind) and Gyrodactylus sp. (13 ind). The highest intensity in the genus Dactylogyrus was 14.06 ind/head in the medium category, while in the genus Gyrodactylus it was 1.86 ind/head in the low category. The highest prevalence value in the genus Dactylogyrus is 100% with the always category while for the genus Gyrodactylus is 19.44% with the frequent category. The data supporting water quality in this study includes temperature, pH, and DO. The temperature of lake water in floating net cages during the study ranged from 23oC-28oC, pH or acidity degree ranged from 8.1-9 and DO range from 4.8-5.6 mg/L. The results of the water quality in this study are classified as optimal for tilapia rearing.

Abstract

Bengkulu City has abundant marine resources, leading in marine capture fisheries volume and value among districts. However, its fishermen remain impoverished due to overfishing, unpredictable weather, and illegal fishing by large vessels, which reduce small-scale fishermen's catches and welfare. This study aims to analyze the income exchange rate of small-scale fishermen's ladders in Bengkulu City and the factors that affect it. Respondents are 100 small-scale fishermen spread across Bengkulu City selected by accidental sampling. Data analyzed using quantitative methods and using SPSS. The results showed that the Income structure of small-scale fisherman households in Bengkulu City consists of income on a fishery by percentage as 80.30% and non fishery income amounting to 19.70% of total income, which is IDR 951,675/week. The consumption expenditure pattern of small-scale fishing households in Bengkulu City consists of expenditure for food by percentage as 51.41% while expenditure for non-food as much as 48.59% of total expenditure, which is IDR 962,230/week. The fishermen's household income exchange rate in Bengkulu is 0.98 < 1, indicating that they cannot fully meet their basic needs and remain relatively poor. The variables of age, fishing hours, catch variations, fishing experience and boat size had a significant effect on the fishermen's household income exchange rate in Bengkulu City. In contrast, the fisherman fisherman education variable did not have a considerable effect on the fishermen's household income exchange rate in Bengkulu City.

Abstract

Lift net is one of light fishing which is occupied to catch small pelagic species. Plenty of studies on lift net have been presented but very view has explored at the biomass size spectrum of Indian Mackerel as a description of fishing intensity and selectivity. Indian Mackerel (Rastrelliger kanagurta) is among other small pelagic species captured by lift net. Observation of biomass size spectrum under different environmental factors aims to describe the selectivity of Indian Mackerel towards lift nets operated at Waralohi waters, Western Seram Regency. Length (cm) and weight (gr) of fish were used to calculate biomass size spectrum. Length of fish ranged from 16.5 cm to 22.5 cm with mean 18.2 cm, median and modus of 18.5 cm. The weight ranged from 16 gr to 149 gr, with mean and median 80 gr and modus 89 gr. Succeed of lift net operation to catch Indian Mackerel occurred during last quarter moon phase. The catch of Indian Mackerel is categorised as juveniles and undersized catch. Biomass size spectra identified that less fishing intensity during full moon affect less vulnerability of small fish being caught. This result should be concerned otherwise growth overfishing could not be avoided.

Abstract

Kasiwa Fish Landing Base (PPI) in Mamuju, West Sulawesi, is a center of fisheries activity that plays an important role in supporting the capture fisheries sector. This research aims to analyze the efficiency of unloading fish catches and the factors that influence it. The method used in this research was purposive sampling, with respondents consisting of active fishermen and port management staff. The aim of this research is to evaluate the duration of the catch unloading process at the Kasiwa Fish Landing Base (PPI) located in Mamuju, West Sulawesi. As the fishing industry advances, the importance of efficiency in unloading procedures becomes increasingly significant to boost productivity and reduce losses. This research uses an observational method with measurements of demolition time carried out over a certain period of time, as well as quantitative data analysis to identify factors that influence the duration of demolition. This includes the type of fish, volume of catch, and weather conditions at the time of unloading. The results show that the time required for disassembly ranges from 30 to 120 minutes, depending on the variables involved. It is hoped that these findings can provide suggestions for fisheries industry players to improve operational efficiency at PPI Kasiwa and become a reference for further research in the field of fisheries and marine product processing.

Abstract

Vibrio parahaemolyticus is one of the bacteria that can attack whiteleg shrimp and cause Acute Hepatopancreatic Necrosis Disease (AHPND) or Early Mortality Syndrome (EMS) in shrimp. One alternative that can be used is the use of seaweed-based immunostimulants, namely k-carrageenan. The purpose of this study was to evaluate the effectiveness of k-carrageenan mixed in feed with different doses on increasing the immune system of whiteleg shrimp infected with AHPND. This study was conducted for 60 days with an experimental method in the form of a Completely Randomized Design (CRD) consisting of 5 treatments and 3 replications, namely, P1 (Positive Control): Commercial Feed + Vibrio parahaemolyticus Infection; P2 (Negative Control): Commercial Feed + 0.9% NaCl Infection; P3: Commercial Feed + Kappa-carrageenan 8 g / kg + Vibrio parahaemolyticus Infection; P4: Commercial Feed + Kappa-carrageenan 10 g/kg + Vibrio parahaemolyticus Infection; P5: Commercial Feed + Kappa-carrageenan 12 g/kg + Vibrio parahaemolyticus Infection. The results of this study indicate that the addition of 12 g/kg of k-carrageenan to the feed affects the survival rate and immune system of whiteleg shrimp infected with Vibrio parahaemolyticus.

Abstract

Choux pastry is a baked product that generally has low fiber content due to its primary ingredient, wheat flour, which contains minimal dietary fiber. Incorporating alternative ingredients rich in fiber can enhance its nutritional value. One such ingredient is Eucheuma cottonii seaweed flour, which is high in dietary fiber and offers potential for innovation in the utilization of fishery-based products. Dietary fiber plays an important role in binding water, improving digestion, and reducing the risk of certain diseases such as cancer. This research aimed to determine the optimal level of Eucheuma cottonii seaweed flour addition to choux pastry based on consumer preference. The study was conducted in December 2024 at the Fishery Product Technology Laboratory, Faculty of Fisheries and Marine Sciences, and at the Chemistry Application Laboratory and PPBS Service Building, Faculty of Mathematics and Natural Sciences, Padjadjaran University. An experimental method was used with four treatments: 0% (control), 7.5%, 10%, and 12.5% seaweed flour. Organoleptic tests (appearance, aroma, taste, and texture) were performed by 25 semi-trained panelists, and proximate analysis was conducted. The results showed that the choux pastry with 10% seaweed flour was the most preferred, with organoleptic scores of 7.8 for appearance, 7.6 for aroma, 7.5 for texture, and 7.7 for taste. Proximate analysis indicated that the 10% seaweed flour choux pastry contained 0.3% crude fiber, 2.9% moisture, 2.28% ash, 27.43% fat, 11.27% protein, and 56.09% carbohydrates.

Abstract

The development of the marine and fisheries sector is a mainstay sector to improve the Indonesian economy (Blue Economy), where aquaculture is a fairly productive and growing sub-sector. Not only sea waters, Indonesia also has very good freshwater potential for development based on aquaculture. Silver barb (Barbonymus gonionotus) is a native freshwater fish from Indonesia and is one of the economical consumption fish that is affordable for the community. The data collection techniques used are primary data and secondary data. This technique is carried out by Primary data, namely data obtained in the field from observations during the implementation of research. Primary data can be in the form of direct observation or observation, namely directly observing the activities carried out such as observing fish growth by looking at the increase in length and weight. Secondary data, namely data obtained from various books, journals, statistical data, articles, and others. Maintenance of silver barb broodstock is carried out by preparing the pond first starting from drying, liming, fertilizing, filling with water, then maintaining the broodstock. Maintenance of silver barb broodstock for 28 days resulted in SR (Survival Rate) values for males of 100% and females of 99%, then FCR (feed conversion rate) for males of 1.64 and females of 1.72. Water quality measurements were carried out 5 times a week and the range obtained was temperature 28-32 ⁰C, pH 8–8.6 and DO (Dissolved oxygen) 8–9.7 mg/l.
