Asian Journal Of Aquatic Sciences is a journal publishes scientific articles from research by lecturers and other researchers in the waters sector. Focusing on aspects of aquatic ecology for the use of this habitat as an ecosystem for producing food (fisheries and agriculture) and its function for the earth's ecosystem. Covers aspects of biology, physics and chemistry, both for freshwater (rivers, lakes, swamps, reservoirs), brackish waters (mangrove swamps, river estuaries) and marine waters (coastal and offshore seas).

Abstract

Transmission of Escherichia coli in food can occur through contact with infected workers, as well as tools and materials used during food processing. One way to determine the presence of E.coli in processed fish balls is to perform a bacteriological test. The purpose of this study was to detect the presence or absence of bacteria in fish balls so that it can be seen whether these meatballs are in the hygienic category and are suitable for consumption or not. This type of research is a laboratory experiment. This research was conducted at the Maluku Provincial Health Laboratory on 26-28 January 2022. The sample used in this study was fish balls taken by purposive sampling (taken according to research needs) for laboratory testing. Based on the results above, it shows that the E.coli bacteria found in the meatball samples during the phenotyping test with Vitek 2 compact both at a dilution of 10-1 to 10-3 were not identified because they had not passed the maximum limit. Based on the results obtained, it was found that the fish balls made by service participants in Mamala country were still in accordance with the criteria of the Indonesian National Standard (SNI) No.7388:2009 regarding the maximum limit of E.coli bacterial contamination in processed meat products made by the government for the protection of consumers regarding the quality of the product in circulation and declared to meet the requirements for the maximum threshold of microbial contamination in food if the value is 3/g for the status fit for consumption. The condition of the value of the test results of the fish balls sample under study is due to the fact that food makers or processors when processing fish balls still use the correct sanitation and hygiene principles and according to procedures

Abstract

This research was conducted in April – June 2021in the Laboratory of Parasites and Fish Diseases, Faculty of Fisheries and Marine, Universitas Riau. Histological preparations were carried out at the Bukittinggi Veterinary Center (BVet). The aim of this study was to analyze the kidney structure of striped catfish (P.hypophthalmus) infected with Edwardsiella tarda with different bacterial densities. The benefit of this research is to provide information about changes in the structure of kidney tissue due to infection with E.tarda, so that later treatment solutions can be sought. The method used was an experimental method with a completely randomized design (CRD) consisting of 4 treatment levels and 3 replications. The treatments applied were P0 (fish not infected with E.tarda), P1 (fish infected with E.tarda at a density of 106 CFU/mL), P2 (107 CFU/mL), and P3 (108 CFU/mL). Striped catfish (P.hypophthalmus) used are 8-12 cm in size with a density of 1 fish/3 L. Infection is done by injection in the intraperitoneal as much as 0.1 mL/fish. The results of the study found that clinical symptoms caused by dull and protruding eyes, dull body surface color, flaky fins, body surface wounds, and bleeding. In histopathological observation, the kidneys with different bacterial densities experienced the highest damage at P3 (108 CFU/mL), namely necrosis, hemorrhage, and hypertrophy.
