“…The decrease in pH that occurs is explained by [8] that fish feed flour tends to reduce the pH become acidic, due to the decomposition process of organic substances. [9] explained that in waters that have a low pH, the dissolved oxygen content decreases, resulting in increased respiratory activity and reduced appetite. This is in line with the results which showing the differences between fish behavior in aerated and unaerated cages.…”

Eutrophication in the Cengklik Reservoir has become a problem that occurs every year which results in the faster growth of water hyacinth (Eichhornia crassipes) around the reservoir waters. This occurs due to increased utilization of the reservoir causing a large amount of waste input into the waters, one of which is from floating net cages aquaculture. Based on the analysis of satellite imagery in 2022, there are approximately 1.355 floating net cage units. The application of intensive aquaculture is considered not optimal because only 70% of the feed is eaten by fish and the rest settles to the bottom of the water. Therefore, there is also an increase in oxygen consumption by fish and microbes for the decomposition process of organic matter.This study aims to increase dissolved oxygen in the waters using injection aeration technology in floating net cages by pumping microbubbles with a diameter of 1 m-1 mm into the water. Aeration was carried out in one floating net cage with a size of 6 m × 6 m for 8 h with 3 stages of dissolved oxygen testing, namely 06.00 (before aeration), 10.00 (after 4 h aeration) and 14.00 (final aeration). The results showed that aeration injection in floating net cages could increase dissolved oxygen 42-58% higher than non-aerated cages. In addition, aeration also increases the appetite of fish in consuming feed. Aeration injection technology can be recommended to improve water quality in Cengklik Reservoir, especially when oxygen is low in the morning.

“…According to Yumame et al (2013), the water pH between 6.5 and 9 is considered suitable for fish farming. Manunggal et al (2018) also stated that a pH value between 7 and 9 is very adequate for pond water. Ivan et al (2019), added that pH changes to acid or base will disrupt the survival of fish because it disrupts the respiration process.…”

The biggest problem that often found in barb hatcheries are the poor hatching rate of eggs. One of the causes of low hatchability is infestation of fungi such as Saprolegnia sp. Prevention of the infestation of fungi could be done by adding natural ingredients such as plants leaves that contain antifungal, such as Jatropha leaf. Soaking Jatropha leaf solution aims to protect the chorion from being infestated by fungi so that it can minimize hatching failure of eggs. The purpose of this study was to determine the effect of soaking Jatropha (Jatropha curcas L.) leaf solution on the hatching rate and survival rate of Java barb (Barbonymus gonionotus) eggs. The testing eggs which were used on this study were originated from male and female broodstock aged 1-1.5 years. Experimental method was carried out using a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The treatments were Jatropha leaf solution at dosages of A (0 g/l), B (2 g/l), C (4 g/l), and D (6 g/l). The data observed were embryonic development, hatching rate (HR), survival rate (SR), and water quality. The results showed that treatments C and D demonstrated fastest embryonic development and hatching phase achieved at 475 minutes. Furthermore, treatment C showed the best value with HR (84.00±3.16%), SR (85.24±1.00%). It can be concluded that soaking eggs using Jatropha leaf solution at concentration of 4 g/L significantly improved hatching rate and survival rate of Java barb (Barbonymus gonionotus).

Red ginger is a natural ingredient that has antibacterial compounds. This research was conducted from June to August 2021 at the Fish Disease and Parasite Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine, Universitas Riau, Pekanbaru. The aim of this study was to obtain the best dose of fermented red ginger added to the feed on the hematology of striped catfish. The method used is an experimental method using one factor Completely Randomized (CRD) with five treatment levels and three replications. The treatments applied were Kn: negative control (no treatments), Kp: positive control (no treatments and infected with A. hydrophila), P1 (150 mL/kg of feed and tested against A.hydrophila, P2 (175 mL/kg of feed), P3 (200 mL/kg of feed). On the 32nd day, the fish were infekted with A. hydrophila at a density of 108 CFU/mL of 0.1 mL/fish intramuscularly, then reared up to 46 days. The results shown that there was an effect of adding fermented red ginger in the feed on the hematology of striped catfish before and after the challenge test with A. hydrophila. The best dose was P2 (175 mL/kg) with a total erythrocyte range of 2.31 x 106 cells/mm3, hematocrit was 39.33%, hemoglobin was 10.40 g/dL, total leukocytes was 11.12 x 104 cells/mm3, survival rate 93.33%, absolute weight growth 19.34 g and water quality during temperature ranged from 28.3-29.2oC, pH 6-7, DO 4.7-5.5 mg/L, and NH3 0.002-0.003 mg/L
