Abstract

The purpose of study is to determine the type of plankton found in cultivation pond of nile tilapia infected by VNN. The method is to identify the plankton in the water pond and testing the VNN that infects nile tilapia related to plankton eaten using Polymerase Chain Reaction (PCR). VNN identification results on the nile tilapia digestive tract stomach and intestines as well as plankton found in the stomach and intestines indicate VNN positively. Plankton found in the digestive tract of fish is division of Chlorophyta, Bacillariophyta, phylum Rotifera and Crustacea. It indicates that nile tilapia infected by VNN both on the gastrointestinal tract organs, stomatch or intestines and plankton were found with positive VNN digestive duct, while plankton found in water pond is VNN negative. The VNN infection depends on the nature of specifications VNN on nile tilapia and the plankton in the nile tilapia digestive duct.

Abstract

Kamal Beach in the Madura Strait is suspected to have experienced heavy metal contamination due to ship recycling industry activities. Heavy metals have a negative impact on the aquatic environment, aquatic biota and even humans. This study aims to analyze the impact of heavy metal content in Kamal Beach, especially heavy metals Fe, Zn, and Cu as heavy metals found in the region on the histopathological aspects of the gill and liver organs of aquatic biota, namely mullet fish (Crenimugil seheli). The levels of heavy metals Fe, Zn, and Cu were analyzed using the AAS (Atomic Absorption Spectometry) method in accordance with SNI 6989.4:2009. Hiatopathological analysis of the gill and liver organs was carried out using the scoring method where from the results of the analysis it was known that the damage that occurred in the gill organs was in the form of edema, hyperplasia, lamellar fusion, and necrosis while damage to the liver organs included degeneration, necrosis, and congestion. Damage to the gill and liver organs of mullet fish is caused by the high content of Zn and Cu in water and sediment.
