The Singapore grouper iridovirus (SGIV), a member of the genus Ranavirus, is a major viral pathogen that has caused heavy economic losses to the grouper aquaculture industry in China and Southeast Asia. No efficient method of controlling SGIV outbreaks is currently available. Systematic evolution of ligands by exponential enrichment (SELEX) is now widely used for the in vitro selection of artif...

Fishborne zoonotic metacercariae have not been reported from brackish water and marine fish from Vietnam waters although these parasites are common in the country's freshwater fish. Both wild-caught and cultured grouper (Epinephelus coioides and Epinephelus bleekeri), and mullet (Mugil cephalus) from brackish and marine waters located in Khanh Hoa province in central coastal Vietnam were examin...

There are gaps in our knowledge of important fish consumed by people tropical countries. Small-scale fisheries difficult to regulate, especially countries with no species monitoring. At Copacabana (Rio de Janeiro), we observed 490 individuals badejo (Comb grouper) (Mycteropeca acutirostris 2013-2014 and 2018-2020. The average catch was 1.36 kg (n=466 individuals). A pattern decreasing catches f...

Patterns of predator dispersal can be critical to the dynamics of prey metapopulations. In marine systems, oceanic currents may shape the dispersal of planktonic larvae of both predators and prey, producing spatial correlations in the recruitment of both species and distinctive geographic patterns of prey mortality. I examined the potential for this phenomenon in two fishes, a wrasse and its gr...

Episode grouper software offers a potential framework for developing important components of a pay-for-performance system for healthcare providers. If the costs for treating health conditions can be computed, then policymakers can in principle benchmark different providers' cost distributions and reward the most efficient. This article applies two of the most prominent commercial groupers and e...

Groupers species are extremely vulnerable to overfishing and many species are threatened worldwide. In recent decades, Mediterranean groupers experienced dramatic population declines. Marine protected areas (MPAs) can protect populations inside their boundaries and provide individuals to adjacent fishing areas through the process of spillover and larval export. This study aims to evaluate the e...

Mass mortalities of sevenband grouper Epinephelus septemfasciatus reared in Oita Prefecture were investigated. The outbreaks of the disease occurred in summer seasons (July to October; water temperature 25-28°C) of 1993 and 1994. Affected fish ranging 170 to l,85Og in body weight were characterized by upside down swimming and inflation of swimbladder. Histopathologically, necrosis and vacuolati...

The tripartite motif (TRIM)-containing proteins exert important immune regulatory roles through regulating different signaling pathways in response to different stimuli. TRIM39, a member of the TRIM family, is a RING domain-containing E3 ubiquitin ligase which could regulate cell cycle progression and apoptosis. However, the antiviral activity of TRIM39 is not explored. Here, a TRIM39 homolog f...

The kelp grouper Epinephelus bruneus (Perciformes: Haemulidae), is one of the most economically important fishery resources in Korea. This fish is regarded as a target for prospective aquaculture diversification; therefore, maintenance of stock quality is important. To investigate the effects of current artificial reproduction in a hatchery facility, genetic variation in wild-caught broodstock ...

Marine protected areas (MPAs) that allow some degree of artisanal fishing have been proposed to control the overexploitation of marine resources while allowing extraction by local communities. Nevertheless, the management of MPAs is often impaired by the absence of data on the status of their resources. We devised a method to estimate population growth rates with the type of data that are usual...
