Taxonomic confusion exists within the genus Epinephelus due to the lack of morphological specializations and the overwhelming number of species reported in several studies. The homogenous nature of the morphology has created confusion in the Malaysian Marine fish species Epinephelus fuscoguttatus and Epinephelus hexagonatus. In this study, the partial DNA sequence of the 16S gene and mitochondr...

In this study we analysed fecal bacterial communities and parasites of three important Indonesian fish species, Epinephelus fuscoguttatus, Epinephelus sexfasciatus and Atule mate. We then compared the biodiversity of bacterial communities and parasites of these three fish species collected in highly polluted Jakarta Bay with those collected in less polluted Indonesian areas of Cilacap (E. sexfa...

Backcross breeding between TGGG hybrid grouper (Epinephelus fuscoguttatus  E. lanceolatus) and giant (E.

Vibriosis disease by Vibrio spp. greatly reduced productivity of aquaculture, such as brown-marbled grouper (Epinephelus fuscoguttatus), which is an economically important fish species in Malaysia. Preventive measures and immediate treatment are critical to reduce the mortality of E. fuscoguttatus from vibriosis. To investigate the molecular mechanisms associated with immune response and host-b...

Lactic acid bacteria (LAB) have been isolated successfully from the tiger grouper intestine. However, their genus or species have not been Epinephelus fuscoguttatus identified. Therefore, the objective of the present study was to characterize the three isolated LAB (KSBU-12C, KSBU-5Da, and KSBU-9) based on their phenotype and genotype. The LAB phenotype was examined by observing morphological f...

A ranavirus was isolated from the diseased farmed groupers (Grouper iridovirus in genus Ranavirus, GIV-R), Epinephelus hybrids (blotchy rock cod, Epinephelus fuscoguttatus ♀×giant grouper, Epinephelus lanceolatus ♂), in Sanya, Hainan, in July 2013. In this study, susceptibility of farmed juvenile giant grouper E. lanceolatus to GIV-R was determined by intraperitoneally injection. The cumulative...

This research aims to study the morphology of Zeylanicobdella arugamensis infesting tiger grouper (Epinephelus fuscoguttatus) at Lampung Bay Waters by using scanning electron microscope (SEM). The samples were obtained from body surface fuscoguttatus). has an elongated silindris with sucker in anterior and posterior. Based on results SEM , parasite a length 4 - 4.1 mm width 0.5 suckers gap midd...
