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.

Madura strait known as the second busiest shipping lanes in Indonesia. Human activities on the environment can influence the marine ecosystem derived from the household, fishery processing and capture fisheries. It can pollute coastal environments, one of which is heavy metal exposure such as Cd, Hg, Ca, As and Pb. These metals are greatly impacting the life of sea biota. The objective of this research, therefore, is to examine the hepatopancreas damage rate of shrimp Neocallichirus karumba due to the exposure of heavy metal Pb in Madura Strait. Method of research is by analyzing Pb content in water, sediment and shrimp by taking sample from 3 different stations. Hepatopancreas damage is then analyzed with SEM-EDX. Result of research indicates that at Station A, Pb pollution in water is the biggest and counted for 0.25 ppm, while those in sediment and shrimp are 5.85 ppm and 1.24 ppm. At Station B, Pb pollution in water is 0.19 ppm, whereas that in sediment is 5.51 ppm, but that in shrimp is 1.04 ppm. At Station C, Pb pollution in water counts for 0.18 ppm, and in sediment, it stands for 5.5 ppm but 0.02 ppm for shrimp. Result of analysis against hepatopancreas damage is explained as follows. At Station A, vacuolization is 20 % and Pb content in organ is 0.520 ppm. At Station B, the parameters are 10% and 0.196ppm. At Station C, it includes 15% and 0.173ppm. Organ damage is straightforwardly related to Pb content in water and sediment. Shrimp age is quite influential to the percentage of organ damage.Keywords: Heavy metal Pb pollution, hepatopancreas organ damage, Madura Strait, N. karumba shrimp.

Pesticides are recognized as serious pollutants in the aquatic environment with the potential to cause genotoxic on the aquatic organism, especially fish. The micronucleus (MN) assay has been used to evaluate genotoxicity of many compounds in polluted ecosystems such pesticides. The aim of this study to determine genotoxic effect of methomyl-based pesticide on tilapia (Oreochromis niloticus). Fish were exposed to six different concentrations base on range finding test (0 ppm, 3.2 ppm, 4.2 ppm, 6.5 ppm, 8.7 ppm and 10 ppm) of methomyl-based pesticide. The micronucleus were collected from peripheral blood erythrocyte of fish after 96 h exposure. Peripheral blood samples smears were stained with Giemsa, MN frequencies were counted and statistically analyzed using one-way ANOVA. The result of this study showed after 96 hours exposed to methomyl-based pesticide, at concentration 0 ppm causes 0% mortality, at concentration to 3.2 ppm causes 30% mortality, at concentration 4.2 ppm causes 60% mortality, at concentration 6.5 ppm causes 70% mortality, at concentration 8.7 ppm causes 80% mortality, at concentration 10 ppm causes 100% mortality of fish test. Lethal Concentration 50 (LC50 - 96 hours) of methomy-base pesticide towards tilapia (O. niloticus) is 4.015 ppm. Through micronuclei assay during 96 hour exposure of methomyl-based pesticide, the result shows that frequencies of micronuclei in erythrocyte of fish test at concentration at 0ppm is 12â€°, 18â€° and 16â€°; at concentration at 3.2ppm is 33â€°, 26â€° and 29â€°; at concentration at 4.2ppm is 41â€°, 38â€° and 46â€°; at concentration at 6.5ppm is 68â€°, 81â€° and 82â€°; at concentration 8.7ppm is 133â€°, 130â€° and 137â€°; at concentration 10ppm is 163â€°, 166â€° and 156â€°. It revealed that methomyl-based pesticide exposure induced after 96 h significantly (P<0.05) increased genotoxic potentials simultaneous with increased concentration.Keywords: Genotoxic, Methomyl, Micronucleus Assay, Pesticide, Tilapia.

Koi herpesvirus (KHV) is a virus that usually infects carp and koi causing mass mortality, as well as economic and social loss. The results of varied test are often found in its development. Allegedly, there are mutation or genetic variation of KHV in Indonesia. Based on these problems, this research aims to understand the genetic variation and kindship of KHV isolate in the carp (Cyprinus carpio) in Lombok Island of West Nusa Tenggara Province based on thymidine kinase sequence. Water quality of fish pond was checked. KHV clinical symptom was checked visually in each fish sample, then sacrifices the organ (gill) for PCR analysis and DNA sequencing. The research results show that clinical symptoms that appear are pale fish gill and bleeding on the surface of the body. The temperature in the research site shows an optimum range for KHV development. The results electrophoresis of carp suspected with KHV shows five positives out of a total six samples. Genetically, KHV isolates from Lombok Island of West Nusa Tenggara Province is identical with the GenBank isolate code KHV-J/U/I and Indo_0C05WNT2.Keywords: Carp, Koi herpesvirus, Phylogenetic, Thymidine kinase.

The viral nervous necrosis (VNN) is betanodavirus of the family Nodaviridae with acute infection and associated with high levels mortality up to 100% of numerous larval-stage marine and freshwater fish species. The danger signals of viral infection that are capable of activating APCs (Antigen Presenting Cells), furthermore produced molecules protein receptors such as interferon and heat shock proteins. Stimulating interferon type I (IFN I) induce several antiviral molecules, further binding the actin cytoskeleton to reach the site of infection. This study demonstrated a correlation between increased levels of Hsp70 (heat shock proteins) and actin filamentous (β-actin) within invasion wild-type isolate of ssRNA VNN from Asian Seabass (L. calcalifer) juvenile. Furthermore, expression of Hsp70 and actin as an indicator or biomarker of stressed states in fish. The reverse transcriptase polymerase chain reaction (RT-PCR) method used to finding expression Hsp70 and β-actin. Whereas nested RT-PCR used for VNN genes. The up-regulation of Hsp70 was observed on the brain tissue higher than eye tissue of sample positive infected VNN. Whereas different expression of β-actin, β-actin receptor expression tends to be stable in the organs of the brain and eye, both invaded VNN or normal, while on the eye, the ratio slightly increased based on the intensity of the band. The research shows that altered expression of heat shock protein 70 and beta-actin gene receptors in the target organs that response to invasion VNN at Asian seabass (L. calcalifer) juvenile. Alteration expression of heat shock protein 70 and beta-actin can be used as an indicator or biomarker of stress cells, especially from VNN invasion at fish. Keywords: Asian seabass, β-actin, Hsp70, Immune response, Viral nervous necrosis.

This research aimed to evaluate antibacterial activity of Dayak onion (Eleutherine palmifolia (L) Merr) extract against fish pathogen Pseudomonas fluorescens. The method used in this study was extraction by maceration, UV-Vis spectrophotometry analysis on the extract and antibacterial activity test with Minimum Inhibitory Concentration (MIC) as well as disc diffusion test. The results of this study showed that the yield value was 8.87%. Based on UV-Vis analysis, it confirmed that extract of Dayak onion (Eleutherine palmifolia (L) Merr) contains predominantly flavonoids and phenols with its derivatives, that have antibacterial activity. The results of MIC and disc diffusion test showed potential antibacterial activity against P. fluorescens, as observed from the value of absorbance and inhibition zones that formed.
