Abstract

This study investigates the abundance and diversity of bacteria associated with two intertidal seaweeds, Sargassum sp. and Kappaphycus alvarezii, in Ekas Bay. Intertidal zones are dynamic environments where seaweeds and their associated microbial communities play crucial roles in ecological processes. Seaweeds host a variety of bacteria that contribute to nutrient cycling, seaweed health, and overall ecosystem function. The primary variable measured in this study was the bacterial abundance, expressed as Colony Forming Units per milliliter (CFU/mL). The conclusion of these findings has positive implications for the environmental health around the floating raft, base stakes, Sargassum sp. and Kappaphycus alverazii. The absence of harmful bacteria supports the sustainability of aquatic ecosystems and can provide positive benefits for the species inhabiting those areas.

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

This study examined the effects of dietary supplementation with Eichhornia crassipes leaf extract on the growth performance and hematological parameters of common carp (Cyprinus carpio). Phytochemical screening confirmed the presence of bioactive compounds such as flavonoids, alkaloids, and saponins, with moderate antioxidant activity (50.89% DPPH inhibition). Experimental treatments showed that fish receiving moderate levels of the extract had significantly higher erythrocyte and leukocyte counts, indicating improved oxygen transport and immune function. Additionally, the group with the highest absolute weight gain suggests better nutrient absorption. All treatments maintained a 100% survival rate and stable water quality, confirming the extract’s safety and environmental compatibility. These results support the use of E. crassipes as a sustainable, cost-effective, and environmentally friendly alternative to synthetic growth promoters in aquaculture. Further research is recommended to investigate its long-term effects and mechanisms of action.
