Comet fish (Carassius auratus auratus) is one type of freshwater ornamental fish that is highly demanded by the ornamental fish hobbyist community because it has a variety of colors and attractive physical forms. However, comet fish cultivation has decreased due to disease attacks that lead to death caused by Aeromonas hydrophila bacteria. Therefore, farmers generally use chemical drugs such as antibiotics to treat diseases in comet fish, yet for antibiotics, and it is necessary to research herbal medicines that contain antibacterial content, such as turmeric (Curcuma domestica). This research aims to determine the effect of immersion time using turmeric extract solution for treatment and survival rate of comet fish seeds infected with A.hydrophila bacteria. This is experimental research with a Completely Randomized Design (CRD) consisting of four treatments and three replicates, namely treatment A (control), B (50 minutes immersion), C (60 minutes immersion), and D (70 minutes immersion). The results showed that using turmeric extract affected treating comet fish seeds infected with A.hydrophila bacteria. As for the survival rate, the results of analysis of variance (ANOVA) showed that the use of turmeric extract had no significant effect, with the percentage value of the survival rate of comet fish seeds of treatment A (63.30%), B (90.00%), C (80.00%), and D (86.60%).

A shortage of seeds and low-quality production of the marine algae Kappaphycus alvarezii are classic problems that farmers encounter. Therefore, growth hormones, a natural ingredient in young coconut water, must be used. This research aimed to analyze the growth rate of the marine algae K.alvarezii using coconut water immersion treatment at different times (0 minutes, 30 minutes, 40 minutes, and 50 minutes) with an initial weight of 50 g. This research was conducted in South Sulawesi, Wakatobi Regency, Wangi-Wangi Selatan District, Liya One Melangka Village from June to October 2023. This research used the RAL method to measure the weight of the marine algae Kappaphycus alvarezii every 10 days and measure water quality for 40 days. The results of the ANOVA analysis in the soaking treatment of K.alvarezii sea algae seeds showed significant effects.

This study aimed to determine the effect of adding Petrofish probiotics to feed at different doses on the growth and survival of barramundi (Lates calcarifer) juveniles. The research utilized an experimental method with 120 barramundi juveniles as test subjects, distributed into treatments A (Control), B 10mL/kg dosage), C (15mL/kg dosage), and D (20mL/kg dosage). The study was conducted for 30 days, using 12 buckets containing ten barramundi juveniles. The research employed a Completely Randomized Design (CRD) with Analysis of Variance (ANOVA), followed by Least Significant Difference (LSD) post hoc tests. The results indicated significant effects for each treatment. The highest absolute weight and length were observed in treatment D at 0.90 g and 0.73 cm, followed by treatment C at 0.77 g and 0.67 cm, treatment B at 0.69 g and 0.62 cm, and the lowest values were in treatment A at 9.51 g and 0.58 cm.
