Abstract

The increase in vaname production is carried out to meet market demand which continues to increase from year to year, so that various strategies are carried out in vaname cultivation. Besides of feed quality and disease prevention, water quality management is an effort to regulate and manipulate environmental conditions so that optimal range can supports shrimp growth, until good shrimp quality is obtained. Location of the activity at PT Bumi Harapan Jaya where has produced a lot of shrimp with the best quality, so it is necessary to know how water quality management is applied there. The method is carried out descriptively, namely describing what is done according to conditions in the field. The results of activities in managing water quality are starting from the preparation of ponds, seeds and good water sources. Water quality management during vaname shrimp rearing activities applies measurements of physical, chemical and biological parameters, where physical parameters such as temperature and brightness are maintained in the range of 27-30°C and 30-45 cm. In addition, the pH remains in the normal range of 7.7-8 and salinity 30-34 ppt. Carrying out regular water quality checks is the key to good water quality management, in addition to that, regular siphoning is also necessary to avoid high ammonia content in the culture water.

Abstract

Silver pompano is a high-value fish, yet the cost of commercial feed is a major challenge for fish farmers. This study explores the addition of turmeric extract to commercial feed as a potential strategy to improve feeding efficiency and reduce production costs. Conducted at the Lombok Marine Aquaculture Center, the 50-day experiment used a Completely Randomized Design (CRD) with four treatment levels (control, 10 ml, 15 ml, and 20 ml of turmeric extract per kg feed) and three replications, totaling 12 experimental units. Parameters measured included growth performance indicators like specific growth rate (SGR), feed conversion ratio (FCR), protein and fat retention, and water quality. Data was analyzed using ANOVA and Duncan tests to assess treatment effects. Results showed that turmeric extract significantly improved SGR, FCR, protein retention, and fat retention, although it had no significant impact on absolute weight, length, survival rate, or feeding efficiency. The optimal treatment was 20 ml/kg of turmeric extract, yielding an SGR of 4.92%, FCR of 2.48, protein retention of 18.64%, and fat retention of 22.37%, likely due to the presence of bioactive compounds such as flavonoids, alkaloids, tannins, terpenoids, and phenols.

Abstract

Siamese fighting fish (Betta splendens) is one of the fisheries commodities in great demand because it has an attractive physique and relatively high economic value. The increasing market demand for male Betta means a method is needed to produce male offspring en masse. This research aimed to determine the effect of bitter melon (Momordica charantia) solution on the male sex ratio of Betta by immersion of larvae in different concentrations. This research used an experimental method with a completely randomized design (CRD), which included four treatments with three replications, namely control treatment, P2 treatment with a concentration of 1.5 ml/l, P3 treatment with a concentration of 3 ml/l, and P4 treatment with a concentration of 6 ml/l. The data obtained was analyzed using the ANOVA method. If the data analysis showed a significant effect, it was carried out using Duncan's advanced test. The research showed that the treatment applied had a real influence on the percentage of male Betta but did not significantly affect the survival rate. The highest sex percentage value for Betta was found in treatment P4 (6 ml/l), which was 77%.

Abstract

The respiratory system of fish is particularly susceptible to parasitic infections and diseases that can cause significant histopathological changes. This article discusses the adaptation of fish's respiratory system to environmental stresses caused by parasites and pathogens, as well as the histopathological changes that occur in response to infection. Some of the major changes observed include hyperplasia, hypertrophy, necrosis, and edema of the tissues in the gills, which can affect the respiratory function of the fish. In addition, granuloma formation and increased mucus production were also noted as adaptive responses to parasitic infections. Although some histopathological changes can improve the fish's body defenses, the tissue damage that occurs as a result of chronic infections can lead to serious impaired respiratory function and decrease the survival of fish. Understanding the mechanisms of adaptation and histopathological changes is very important for fish health management, especially in aquaculture, in order to reduce the negative impact of diseases and increase fish productivity.

Abstract

The demand for Siamese catfish seeds continues to increase every year. Therefore, it is essential to maintain high-quality seeds in adequate quantities, supported by the availability of natural feed such as bloodworms (Tubifex sp.). One of the efforts to improve hygiene and reduce pathogenic bacteria is through the sanitation treatment of feed using fermented tofu waste and mustard greens waste. The fermentation of tofu waste and mustard greens has a high protein content, which can enhance the nutritional value essential for the growth of fish seeds. The objective of this research is to analyze the effectiveness of using hygienic bloodworms treated with fermented tofu waste and mustard greens waste on the performance of Siamese catfish seed breeding. The method employed is a Completely Randomized Design (CRD) with four treatments and three replications. The research data were analyzed using ANOVA statistical tests and Tukey's post-hoc test at a 5% significance level. The sanitation treatment of feed with the addition of fermented tofu waste and mustard greens resulted in the highest nutritional content and the highest abundance of beneficial bacteria on the fifth day of maintenance. The results showed a significant effect () on the absolute growth and specific growth rate of Siamese catfish seeds. The absolute length growth of the Siamese catfish seeds was 9.37±0.044 mm, while the absolute weight growth was 0.08±0.0169 grams. The specific length growth rate of the Siamese catfish seeds was 7.10±0.017%, and the specific weight growth rate was 18.35±0.025%. The survival rate of Siamese catfish seeds across all treatments reached 98%. The sanitation treatment of natural bloodworms with fermented tofu waste and mustard greens is recommended to enhance the nutritional content of bloodworms and accelerate the growth of Siamese catfish seeds.

Abstract

Fisheries are an important economic sector for many countries, including Indonesia. Bone Bay has high potential for skipjack (Katsuwonus pelamis) fishing. This study aims to map potential skipjack fishing zones in Bone Bay and analyze the relationship between sea surface temperature, salinity, and chlorophyll-a concentration with the catch of these fish. Using quantitative methods and probability sampling techniques, primary data were obtained through direct observation of fishing activities using the pole and line method, while secondary data were obtained from satellite images downloaded from the Oceancolor website. The results showed that the potential zones for skipjack fishing are located at coordinates 3o0’0”LS-4o30’0”LS and 120o30’0”BT-121o0’0” BT. The findings are expected to help stakeholders make strategic decisions for more effective and susstainable fisheries management.
