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

Ornamental fish farming is identical to attractive colors formed from the union of genetics and digested feed sources. Exploration and processing of feed ingredients are one of the important factors added to feed formulations to increase brightness in fish. Pigment sources are divided into 2, namely natural pigment sources (plant and animal), and synthetic pigment sources as commercial materials. The application of pigment source feed ingredients is used as feed additives (nutritive and non-nutritive) which are added or mixed in the formulation. The preparation technique for adding pigment sources is carried out by spray drying, and coating (coating) in feed. Feed additives in commercial ornamental fish feed formulations can be in the form of active substances astaxanthin (C₄₀H₅₂O₄) and beta-carotene (C₄₀H₅₆) which give red-orange color, or in the form of alternative feed ingredients from spirulina, carrots, and pumpkin which give yellow and orange colors. Astaxanthin and beta-carotene dyes have been proven effective in enhancing the brightness of color in ornamental fish at a dose of 1500 ppm. The aim of the review is to provide information and insight regarding pigment source feed ingredients as well as related processing of pigment source materials using several extraction methods. The method used in this review is based on the results of a literature study using articles that have been searched on Google Scholar for the period 2012-2024. Each journal used has the results of research on pigment source materials, processing of pigment sources and their application for pigments in fish.

Abstract

Mud crab (Scylla spp.) aquaculture holds significant potential in supporting food security, economic growth, and ecological balance. This study aims to summarize various findings related to critical factors in mud crab farming, such as feed types, rearing systems, and stocking density, and their impact on productivity, feed conversion ratio (FCR), and economic profitability. The review highlights that trash fish feed at 15% of body weight yields optimal growth and feed efficiency due to its high protein content. Feed diversification, including stingray and janitor fish, offers promising results with reduced costs. Various rearing systems are employed, ranging from cages and earthen ponds to advanced technologies such as Recirculating Aquaculture Systems (RAS). Small bamboo floating cages demonstrate superior outcomes in growth and survival rates (SR). Mangrove habitats significantly enhance crab growth, while silvofishery systems provide a sustainable farming alternative. Optimal stocking density, such as 4 crabs/m², balances growth and production. Additionally, Scylla serrata exhibits the best growth rate compared to other species, particularly males. Innovations like soft-shell farming technology add economic value to the product. Overall, the success of mud crab aquaculture depends on the optimal combination of feed, rearing systems, and environmental management. This review offers strategic insights for developing efficient, sustainable, and economically viable crab farming practices.

Abstract

Indonesia is a maritime country that has great potential in the fisheries sector, especially in cultivating vaname shrimp (Litopenaeus vannamei). Disease in vaname shrimp is the biggest factor causing cultivation failure, one of which is caused by IMNV (Infectious myonecrosis virus). The aim of this research is to study IMNV detection techniques in vaname shrimp using the PCR (Polymerase Chain Reaction) method at the Situbondo Brackish Water Aquaculture Fisheries Center. This research uses a descriptive method, with stages starting from necropsy, RNA extraction using the silica method, amplification using RT-PCR and Nested-PCR, to electrophoresis and documenting the results using UV documentation. The results showed that the PCR technique was effective in detecting IMNV in shrimp, with DNA amplification clearly visible through agarose gel electrophoresis. Documentation of PCR results indicated the presence of a DNA band in the IMNV positive sample, which corresponded to the positive control. In conclusion, IMNV detection using the PCR method at BPBAP Situbondo has proven to be effective for identifying disease in vaname shrimp and can be applied as an initial step in controlling disease in vaname shrimp cultivation.

Abstract

Sea grape (Caulerpa lentillifera) is a strategic green macroalgae with significant potential in aquaculture and functional food industries. However, its cultivation remains constrained by limited production techniques. This study investigated the influence of nitrogen concentration on C. lentillifera growth in a laboratory-scale cultivation system. A completely randomized experimental design was implemented with four treatments: a control group (0 ppm) and nitrogen supplementation levels of 5, 10, and 15 ppm, each replicated thrice over 21 days. Results demonstrated a significant positive correlation between nitrogen concentration and growth parameters. The 15 ppm nitrogen treatment exhibited the highest absolute growth (3.37 g), relative growth rate (13.50%), and specific growth rate (1.82% per day). Interestingly, no statistically significant difference was observed between 10 and 15 ppm treatments, suggesting a potential nitrogen uptake saturation point. Water quality parameters remained stable throughout the experiment, with temperature ranging from 28-30°C, salinity at 33-34 ppt, dissolved oxygen between 5.9-6.7 ppm, and pH maintained at 7.5-7.8. The study provides crucial insights into nitrogen's role in C. lentillifera cultivation, offering a scientific foundation for developing more efficient and sustainable macroalgae production strategies in aquaculture and functional food industries.

Abstract

Freshwater prawn (Macrobrachium rosenbergii) is a freshwater species which intensively cultivated. Calcium (Ca) and magnesium (Mg) are crucial factors supporting the biological and physiological activities of freshwater prawns. The presence of calcium and magnesium minerals in the environment is utilized by the prawns, especially after the molting process. Calcium and magnesium play roles in osmoregulation and the formation of the prawn's carapace. This study aims to determine the optimal ratio of calcium and magnesium minerals to support molting frequency, specific growth rate, survival rate, and feed efficiency.The experimental design used in this research is a completely randomized design (CRD) with five treatments and three replicates. The treatment given consisted of increasing Ca-Mg in the media: A: 30 mg l-1 Ca + 0 mg l-1 Mg (1:0); B: 30 mg l-1 Ca + 15 mg l-1 Mg (1:0.5); C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1); D: 30 mg l-1 Ca + 45 mg l-1 Mg (1:1.5) and E: 30 mg l-1 Ca + 60 mg l-1 Mg (1:2). Based on the result, treatment C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1) was found to improve molting frequency, growth rate, feed efficiency and survival rate.
