“…The highest hatching rate of barramundi eggs within 14 hours of observation in treatment P3 with a dose of 4 ml/L was 90.33%. The value of the egg hatching rate obtained in this study almost coincides with 92.33% with the value of the hatching rate of eggs from research results [26] on the effectiveness of using chemical disinfectants to Prevent fungal attacks on Labeo bata fish eggs. The dosage of 4 ml/L is the dosage containing active ingredients such as alkaloids, flavonoids and other antifungal substances that are completely optimal and suitable for barramundi, so at this dosage the eggs hatch well.…”

Barramundi is one of the preferred fishes in great demand because of its delicious taste and high nutritional content. One factor that influences the success of culture is hatchability and high larval survival. In the business of barramundi aquaculture, problems are often encountered, namely the presence of fungi that attack fish eggs. Precautions and treatment use of continuous synthetic compounds with improper concentration will cause new problems. The traditional pecut kuda anti-fungal, this plant is also easily obtainable and easy to use in the prevention and treatment of fish diseases. The purpose of this study was to analyze the success rate of using pecut kuda (Stachytarpheta jamaicensis L. Vahl) in increasing the hatchability of barramundi eggs and observing the growth of barramundi larvae. This research was conducted on July 25 – August 16, 2022. Located at Brackish Water Cultivation Fishery Center, Ujoeng Batee, Aceh. This research method used a completely randomized design with 5 treatments and 3 replications, namely P1 (0 ml/control), P2 (2 ml/L), P3 (4 ml/L), P4 (6 ml/L), and P5 (8 ml/L). Observation of the data collected during the research was presented in the form of tables and graphs. The results showed that pecut kuda leaf extract at different doses affected the hatchability of eggs, percentage of fungus attack, and mortality of barramundi larvae, while it did not affect the abnormality and growth length of barramundi larvae. The best treatment at P3 with a dose of 4 ml/L was 90.33% of the hatching rate with a low mortality value of P3 was 11.80%.

The oomycete Saprolegnia sp. infects freshwater fish, resulting in mortality and economic loss in fish farms (Shaalan et al., 2018). This pathogen affects fish in all development stages, from eggs to adults.It damages the chorionic membrane of eggs, quickly infecting all spawning and killing viable eggs (Liu et al., 2014). Pterophyllum scalare is among the fish species that are sensitive to this disease (Eissa et al., 2013).Currently, few chemical products are legal to control fungal disease in Brazilian aquaculture, although some chemotherapy drugs have been used such as malachite green, iodopovidone, formalin,

The effect of cinnamaldehyde (CA) towards Streptococcus agalactiae on zebrafish egg was investigated. CA and S. agalactiae were tested by short-term effects assay. Fresh zebrafish egg, CA and S. agalactiae were observed in different groups, single and mix treatment. The result showed that the larval survival rate (%) of single CA concentration (2.5 and 5 µg mL-1) were not significantly different compared to the control, with the value 94±2.8% and 93±3.3% respectively. S. agalactiae with a single concentration (10 9 and 10 10 CFU mL-1) was significantly different in comparison to the control with the value 73±2.1% and 6±2.5%. Mix groups, larval survival rate (%) value were significantly different with the best combination value was 17±4.7% at 5 µg mL-1 of CA and 10 9 CFU mL-1 of S. agalactiae. CA may potential for zebrafish egg shelter against S. agalactiae infection. Mixture (CA and S. agalactiae) treatments were not recommended because the low value was shown compared to the single treatments. This possibility may occur because of the debris formation of two substances which leads to the poor environment and causes to low fish larval survival rate (%) value. For further study, the water quality assay is needed.
