Fish Diseases and Environment Monitoring in aquaculture areas is one of the efforts made to determine the spread of fish disease attacks as early as possible and to determine the condition of water quality in Aquaculture. Monitoring is carried out at several cultivation locations in Lampung province which carried out in January - December 2023.The 161 fish samples obtained for examination purposes were dominated by Pompano (Trachinotus sp.)82%. The results of diagnostics and laboratory examinations show that fish diseases are caused by parasite infestations, bacterial infections and viral infections.
Fish health and the cultivation environment are factors that can support the success of aquaculture businesses. Fish farmers are advised to always monitor the health of fish and the condition of the water quality in the cultivation environment so that the spread of disease and a decrease in the quality of fish farming water can be anticipated before they cause losses to fish farming business actors.
This monitoring carried out in January - December 2023 in several places, namely in the waters of Lampung Bay (Hurun Bay, Pasaran Island, Puhawang Island, Ringgung), East Lampung Regency (Pasir Sakti), South Lampung (Kalianda and Bakauheni).
The purpose of this monitoring is to detect, diagnose and determine the causes and distribution of diseases of fish and shrimp culture, to know the condition of water quality at cultivation locations in ponds, seas, and hatcheries as a complete piece of information for managing fish health and the environment.
The parasites found were Pyragraphorus sp., Trichodina sp., Pseudorhabdosynohus sp., Benedenia sp., Neobenedenia sp., Uronema sp. The infecting bacteria are Vibrio alginolyticus, Vibrio parahaemolyticus and Pseudomonas fluorescens. Virus detection using the PCR method shows that the VNN (Viral Nervous Necrosis) virus infects the Grouper and Pompano fish. Vanamae shrimp samples were found to be infected with the WSSV, IMNV viruses, and were positive for EHP.Water quality in the Hurun Bay area, the concentrations of Nitrate and Phosphate have exceeded the quality standard, the phytoplankton composition with an average of 72.6% diatoms; 15.6% dinoflagellates and others 6.1%, as well as the identification of HAB’s types of diatoms Pseudo_nitzchia with the highest abundance of 25,000,000 cells/L, and dinoflagellates Protoperidinium sp. with the highest abundance of 10,852 cells/L, Cochlodinium polykrikoides with the highest abundance of 614 cells/L and Noctilucascintillans 1,184 cells/L.
