Abstract

ABSTRAKThis research was conducted from March to June at the Laboratory of Fish Parasites and Diseases, the Marine Microbiology Laboratory and the Marine Chemistry Laboratory of the Faculty of Fisheries and Maritime Affairs, Riau University, Pekanbaru. The purpose of this study was to analyze the effectiveness of heterotrophic bacteria to improve water quality and body resistance of salted tilapia (Oreochromis niloticus) from haematological (Erythrocytes, hematocrit, hemoglobin and leukocytes) against disease.The method used in this study is an experimental method, using a Completely Randomized Design (CRD), 1 factor, namely with five levels of treatment three replications. Kn: Without administration of heterotrophic bacteria, without being tested, Kp: Without administration of heterotrophic bacteria, tested by Aeromonas hydrophilla bacteria, P1G: Giving heterotrophic bacteria Vagococus fluvialis at a dose of 15ml /25L, P2G: Giving heterotrophic bacteria Bacillus cereus at a dose of 15ml/25L, P3G: Provision of combined heterotrophic bacteria Bacillus cereus and Vagococus fluvialis at a dose of 15ml/25L. The results showed that the best treatment was P3 treatment using combined heterotrophic bacteriaBacillus cereus and Vagococus fluvialis. This is based on the value of blood parameters after the challenge test with Aeromonas hydrophila bacteria showing total erythrocytes of 252.33x104 cells/mm3, total leukocytes 90.13x103 cells/mm3, hemoglobin levels 8.03 g/dL, hematocrit 32.23%, survival rate 96, 66% and absolute weight growth of 4.82 g/head. The results of measurements of water quality during the study temperature range between 27-27.40C, dissolved oxygen 1.8-2.3 ppm, pH of water ranged from 7.8 to 7.9. Keywords: Heterotrophic Bacteria (B. Cereus and V. Fluvialis), Salted Tilapia (O. Nilloticus)

Abstract

Striped catfish (Pangasianodon hypophthalmus) is a widely cultivated type of superior food fish. Intensive cultivation of catfish can cause disease. Feeding striped catfish with guava leaf extract is expected to reduce stress, which can be seen in striped catfish's hematological and physiological conditions. This research aims to obtain a dose of guava leaf extract (Psidium guajava L) to improve the health of striped catfish. The method used in the study was an experimental method that applied a one-factor, Completely Randomized Design (CRD) with five treatment levels. The treatment used was without adding guava leaf extract (P0); P1, P2, P3, and P4 with doses of 25, 50, 75, and 100 mL/kg feed, and all treatments were tested against Aeromonas hydrophila. The fish used in this research were 250 striped catfish seeds measuring 6-8 cm and kept for 45 days. Feeding with the addition of guava leaf extract at a dose of 75 mL/kg of feed had an influence on the hematological and physiological profile of post-challenge catfish, such as total erythrocytes of 2.40x106 cells/mm3, hematocrit 35.66%, hemoglobin levels 9.61 g/dL, total leukocytes 10.54x 104 cells/mm3, blood glucose levels of 78.00 mg/dL and phagocytic activity 35.66%. Absolute weight growth 17.76 g, feed efficiency 41.07%.
