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.

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.

The presence of plankton is very important for aquatic ecosystems. Kalianda Coastal Beach has direct access to the open sea. Its water condition can experience changes including physical, chemical, and biological conditions. Moreover, the beaches in the Kalianda coastal area are widely used for vannamei shrimp breeding, ferry port, fishery and trade port. The purpose of this study was to evaluate the structure of the plankton community, including abundance and species composition, diversity index, uniformity, and dominance. This study used data from water sources in three vannamei shrimp nurseries located in Kalianda Coastal Beach, South Lampung. Water parameters observed in Kalianda Coastal were plankton, salinity, pH, nitrate, ammonia, dissolved solids (TSS), and phosphate. The results showed that the plankton found in Kalianda coastal area consisted of four classes, phytoplankton namely Bacillariophyceae (78.75%) and Dynophyceae (9.85%), zooplankton Ciliata (7.79%) and Crustacea (3.61%). The range of phytoplankton abundance is 2392-3029 cells/l, while the abundance of zooplankton is 279-414 ind/l. Plankton diversity and uniformity indices are high meaning that the plankton community in Kalianda Coast is very diverse and stable, low dominance means that there are plankton that dominate, namely from the Bacillariophyceae class. The structure of the plankton community in Kalianda Coastal Beach shows a stable condition at the time of the research. To know the plankton community structure more thoroughly, it is necessary to take plankton samples every season with more station points.

Osteochilus spilurus is one of native fish in Indonesia. This species from North Lampung has variations in body shape with populations in Bangka and Belitung. Morphological plasticity and genetic variation are potential causes of these differences. To confirm this, it is necessary to identify molecular using the mitochondrial cytochrome b (cyt b) gene. Fish samples from North Lampung had morphological characters matched to the description of O. spilurus. This research specimen was registered at the Bogor Zoological Museum as a supplementary note from Lampung. The phylogenetic construction shows a closer relationship between fish samples from North Lampung and O. spilurus from Bangka-Belitung, but there is a wide genetic distance between them. Genetic variation between islands that occur is predicted due to differences in ancient river flows in the past and the geographical isolation of the oceans for thousands of years.Keywords: Cytochrome b; Lampung; Osteochilus spilurus; Genetic Variation

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.
