The Effect of Giving Herbal Medicine Feed with Different Doses on the Growth and Survival of Striped Catfish (Pangasius sp.) Kept Using a Resirculation System
Catfish (Pangasius sp.) is one of the superior freshwater fish commodities in Indonesia which is in great demand by local and foreign communities because the price is relatively affordable. The high demand for patin fish in the market has resulted in many people switching to cultivating patin fish as a livelihood. In cultivation activities, one aspect related to the growth of catfish is feed. The method used in this study is an experimental method using a Completely Randomized Design (CRD). The purpose of this study was to obtain the best dose of feed supplemented with herbal feed in catfish maintenance using a recirculation system. The placement of each treatment in the experimental unit was carried out randomly. The treatments given were PO: Control, P1: 100 ml / kg feed, P2: 200 ml / kg, P3: 300 ml / kg, P4. 400 ml / kg. The best treatment was obtained in treatment P3 with a dose of 300 mL/kg feed which resulted in absolute weight growth of 2.31±0.01 g, absolute length growth of 1.32±0.01 cm, specific growth rate of 1.5310.01%/day, survival rate of 100%, feed conversion ratio of 1.07±0.01 kg

The treatments were: A: 0 mL/kg of feed (control), B: 50 mL/kg of feed, C: 75 mL/kg of feed, and D: 100 mL/kg of feed. The herbal supplements were consisted of turmeric, and ginger with Bacillus sp. and yeast (Rhizopus oligosporus). The results showed that a different doses of additional herbal supplements affecting the growth performance and the survival rate of catfish using recirculation system. In addition, it also affected the absolute weight growth, absolute length growth, feed efficiency and feed conversion ratio.The optimal dose was at 100 mL/kg of feed as it showed significantly different results compared to control. So that while being applied in terms of economy, 100 mL/kg was the most efficient dose, by giving the specific growth rate was 1,55%, survival rate was 98,3%, absolute weight growth was 8,67 g, absolute length was 6,23 cm, feed efficiency was 79,53% and feed conversion ratio was 1,26.
Isolation of Lactic Acid Bacteria from Intestines of Eel (Monopterus albus) Raised in Biofloc System Cultivation
Biofloc technology is one of the most profitable alternative solutions to the problem of aquaculture waste. The research was carried out from July to August 2020 at the Laboratory of Fish Parasites and Diseases, Faculty of Fisheries and Marine Affairs, Riau University. The purpose of this study was to isolate and identify candidate lactic acid bacteria (LAB) that have the potential as probiotics from the intestines Monopterus albus and to determine the growth rate of candidate probiotic bacteria and can suppress the growth of the pathogenic bacteria Aeromonas hydrophila. The method used is the experimental method with treatment of pH 2, pH 4 and pH 6, isolation was carried out from the best Monopterus albus rearing with a stocking density of 30 fish/25 liters of water. Candidate probiotic bacteria was found from the intestines of Monopterus albus as many as 6 LAB candidate isolates based on the results of physical, biochemical and pH treatments, the morphology of the probiotic candidate isolates consisted of one type of bacteria, namely Lactobacillus, from the 6 isolates which showed the widest zone of inhibition against the pathogenic bacteria Aeromonas hydropila was isolate derived from Monopterus albus intestine result shown that which grows at pH 2 is BL 2.1.1 with an inhibition zone diameter of 9,05 mm.
Rearing Hoven’s Carp (Leptobarbus hoevenii) by Feeding Fermented With Herbal Supplements in a Recirculation System
Study aims to determine the best dose in rearing hoven’s carp (Leptobarbus hoevenii) by feeding fermented feed with herbal supplements in a recirculation system.

The research method used is the experimental method using a Completely Randomized Design (CRD) which consists of 4 levels of treatment, namely A (100% tofu); B (75% tofu+ 25% fermented taro leaf midrib); C (50% tofu + 50% fermented taro leaf midrib); D (25% tofu + 75% fermented taro leaf midrib). Parameters observed were BSF maggot length and weight growth, digested feed conversion efficiency (ECD), waste reduction index (WRI), BSF maggot productivity. Analysis of the data used was Analysis of Variance (ANOVA) and to determine the best treatment using a follow-up test in the form of Duncan's test with a significance level of 5%. The results showed that different combinations of tofu and fermented taro leaf midrib had a significant effect on the growth of Maggot BSF. The best combination of tofu and fermented taro leaf midrib on the growth of Maggot BSF was the use of 75% tofu + 25% fermented taro leaf midrib which has a significant effect when compared to other treatments
Phytoremediation of Catfish (Clarias gariepinus) Aquaculture Waste Using Giant Salvinia (Salvinia molesta) And Water Lettuce (Pistia stratiotes)
This research was conducted with the aim of knowing the ability of giant salvinia (Salvinia molesta) and water lettuce (Pistia stratiotes) aquatic plants to improve the quality of catfish (Clarias gariepinus) aquaculture wastewater with parameters of temperature, acidity (pH), dissolved oxygen (DO), ammonia and organic matter. This research was conducted for 20 days and used a Randomized Block Design (RBD), with observation and sampling time on days: 0, 5, 10, 15, and 20, treatment K as control (without aquatic plants), giant salvinia (KI)) and water lettuce (KA). The results showed that the phytoremediation process using aquatic plants, water lettuce, and giant salvinia, had a significant effect on improving the quality of wastewater from catfish aquaculture waste. Water lettuce was able to reduce ammonia levels by 97.81% and organic matter by 33.19%, while giant salvinia was able to reduce ammonia levels by 97.23% and organic matter by 20.00%. This shows that in improving the quality of catfish aquaculture waste, water lettuce (Pistia stratiotes) is more effective than giant salvinia.
