Backcross breeding between TGGG hybrid grouper (Epinephelus fuscoguttatus E. lanceolatus) and giant grouper (E. lanceolatus)
This paper reports on the first successful backcross breeding between TGGG hybrid grouper and GG in captivity. To establish a seed production technique for this new backcross grouper, eggs and larval development were observed. Three successful spawning was observed in November 2018, September 2019 and November 2019. The eggs were collected using stripping methods and the sperms were collected u...
متن کاملSusceptibility of farmed juvenile giant grouper Epinephelus lanceolatus to a newly isolated grouper iridovirus (genus Ranavirus).
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...
متن کاملHistological assessments of intestinal immuno-morphology of tiger grouper juvenile, Epinephelus fuscoguttatus
Histological assessments on the intestinal morphology and immunity of tiger grouper juveniles, Epinephelus fuscoguttatus help in determining the earliest age to start an oral vaccination. This study describes the morphological development of the intestinal immunity of tiger grouper of various ages. Clinically healthy tiger groupers were selected and divided into 4 groups of 20 fish per group. G...
متن کاملCharacterization of 10 novel microsatellite loci for the brown marbled grouper, Epinephelus fuscoguttatus (Serranidae).
Epinephelus fuscoguttatus is a commercially important marine fish species in southeast Asia. Due to overfishing and water pollution, this species has been declared as near-threatened. Thus, to provide information to help maintain and preserve the species, microsatellites were developed, using an enriched genomic library method. Thirty individuals were collected from the hatchery of the Fishery ...
متن کاملSerum cortisol concentrations change in tiger grouper, Epinephelus fuscoguttatus in response to water temperature and salinity stress
The present exposition was designed to evaluate blood serum changes in tiger grouper, Epinephelus fuscoguttatus in response to changes in water temperature and salinity. Uniformly sized fingerlings were randomly distributed into different groups at fifteen fish per tank, in two replicates. Each group represented experimental fishes subjected to water temperatures of 18, 24, 28 and 30°C (control...
