Rubber cassava root (Manihot glaziovii) bark contains an active substance known as Hydrogen Cyanide (HCN), which is toxic to red-blooded animals. This bark is abundant and readily available in the community’s surroundings. Therefore, this research aims to investigate the effect of using rubber cassava root bark at specific doses in eradicating red-blooded fish. The test animals used are Nile tilapia (Oreochromis niloticus). Each treatment is repeated three times and assigned specific codes: code A as a control with the application of 20 ppm saponin, and codes B, C, and D with the application of rubber cassava root bark liquid at 20 ppm, 40 ppm, and 100 ppm, respectively. The parameter used as the observation criterion is the mortality rate of the test animals over 6 hours with varying doses of rubber cassava root bark liquid. Based on the research results, it can be concluded that rubber cassava root bark liquid can be used as an alternative to replace saponin at 100 ppm. Further research is required to determine the most effective dose of rubber cassava root bark as a substitute for saponin in aquaculture.

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.

In addition to having high economic value, catfish (Clarias sp.) can also be cultivated quickly and they can adapt well. The demand of catfish is in line with the increase in production which is expected to remain efficient and environmentally sound. Biofloc technology has also been implemented in catfish for increasing productivity. Biofloc utilizes the activity of heterotrophic microorganisms and autotrophs for the conversion of organic waste into floc and is used as fish feed. This study aims to examine the effect of the use of molasses with different doses (C/N ratio) on the growth and survival rate of catfish. This study was conducted with as many as 3 treatments with 3 repetitions each except for the control. The treatment with the ratio of molasses in each of them: A: C/N of 10:1; B: C/N of 15:1; C: C/N of 20:1, and D without molasses given as control. The study using 240 catfish measuring 10-12 cm was carried out for 30 days with sampling every 10 days. It aims to determine the average growth, daily growth, and survival rate of test biota during the study. Based on the results of this study, it can be concluded that the use of different doses of molasses in catfish farming, and biofloc technology will affect the growth and survival rate of farmed catfish. Catfish farmed with biofloc technology at a C/N ratio of 15:1 show the best results on their growth and survival rate. In addition, catfish farming with a biofloc C/N ratio of 15:1 has a better economic analysis when compared to conventional catfish farming. In summary, the use of biofloc based on research results can be a recommendation to be applied in the community, especially among catfish farmers.

Red Nile Tilapia (Oreochromis niloticus L.) is one of the important commodities in aquaculture, possessing high economic value and promising prospects for supporting the economy and food security. Various efforts have been made to increase fish production, one of which is through the use of feed additives. Probiotics have been widely used in aquaculture, either as a feed supplement or applied directly to the culture media. This study aims to compare the growth, survival rate, and condition factor of Red Nila Tilapia fed with probiotic-supplemented feed and those without probiotics. The study was conducted over 84 days using Red Nila Tilapia measuring 6.8 cm, stocked in earthen ponds at a density of 10 fish/m². The results showed that Red Nila Tilapia fed with probiotic-supplemented feed had a higher growth performance compared to those without probiotics. The average daily growth rate and survival rate of fish given probiotics were 2.06 g/day and 87%, respectively, whereas fish without probiotic supplementation had 1.70 g/day and 84%. Conversely, fish fed with probiotics exhibited a condition factor of 1.06, which was lower than the 1.69 recorded in fish without probiotics. The findings of this study indicate that probiotics can be used as a feed additive for Red Nile Tilapia, providing positive effects on growth, survival rate, and fish health.

Sand lobster (Panulirus homarus sp.) is one of the promising fishery commodities with high economic value and is considered a leading export species in Indonesia's fisheries sector. The cultivation of sand lobster using floating net cages (KJA) in the sea still faces many challenges. Therefore, innovative cultivation technologies for lobsters are urgently needed. This study aims to assess the growth performance and survival rate of sand lobsters cultivated in a closed system (indoor system). The research was conducted using four fiberglass tanks measuring 4 x 2 x 1 m (water height 0.5 m). The average initial body weight (IBW) of the lobster seed used was 79.8 ± 5.8 (mean ± SE) with a stocking density of 10 individuals/m². The feed provided consisted of trash fish and golden apple snails, with a feeding rate of 15% of the total biomass. Growth sampling was conducted every three weeks. Sand lobsters cultivated for nine weeks (63 days) had an average final body weight (FBW) of 91.1 ± 5.2 grams/individual. The weight gain (WG) and specific growth rate (SGR) of the sand lobsters during the study were 14.2 ± 1.5% and 0.22 ± 0.02%, respectively. The feed conversion ratio (FCR) during the study was 10.1 ± 0.1, while the average daily growth (ADG) was 0.19 ± 0.01 grams/day. The survival rate (SR) of the sand lobsters decreased over the maintenance period, reaching 75.6 ± 2.8% by the end of the study.

The vannamei shrimp (Litopenaeus vannamei) is one of the most popular shrimp species, widely cultivated throughout Indonesia. This species has several advantages, including rapid growth, the ability to be cultivated at high densities in intensive systems, and resilience to environmental changes. The presence of plankton and the quality of water in the cultivation medium significantly affect the growth and survival of vannamei shrimp. This study aims to evaluate plankton abundance and the dynamics of water quality in intensive vannamei shrimp farming. The research was conducted at two intensive vannamei shrimp farms in East Java with shrimp aged between 1 and 60 days. Water quality measurements were taken directly from the cultivation ponds (salinity, pH, and dissolved oxygen) and in the laboratory (ammonia, nitrite, phosphate, alkalinity, and total organic content). The average abundance of plankton in the intensive vannamei shrimp farming medium ranged from 190 x 10³ to 960 x 10³ individuals/mL, consisting of four groups: green algae, diatoms, dinoflagellates, and blue-green algae. Green algae were the most abundant group, making up 69.9% to 71.9%, while diatoms were the least abundant at 1.9% to 3.0%. In intensive vannamei shrimp farming, the salinity of the cultivation medium ranged from 16 to 35 ppt, pH from 7.5 to 9.0, dissolved oxygen from 3.2 to 5.7 mg/L, and temperature from 28.0 to 31.3°C. The water chemistry parameters measured were ammonia, nitrite, phosphate, alkalinity, and total organic content, with respective ranges of 0.001–0.030 mg/L, 0.05–1.00 mg/L, 0.25–3.00 mg/L, 104–232 mg/L, and 27–131 mg/L. The dynamics of water quality remained within the optimal range for vannamei shrimp farming, as outlined in Regulation KP Number 75 of 2016 regarding general guidelines for the rearing of tiger shrimp and vannamei shrimp.
