residual levels of ddts and pahs in freshwater and marine fish from hong kong markets and their health risk assessment.	axial and ventral muscle from 10 each species of freshwater and marine fish purchased from markets in hong kong were analyzed for dichlorodiphenyltrichloroethane (total ddts including dde, ddd and ddt) and polycyclic aromatic hydrocarbons (pahs). among the 10 freshwater fish species, rice field eel (monopterus albus) showed significantly higher levels of ddts in both ventral (125 ng/g wet wt) and axial muscle (127 ng/g wet wt) than the other species. the highest concentration of pahs was detecte ...	2007	16870232
risk assessment of pcdd/fs levels in human tissues related to major food items based on chemical analyses and micro-erod assay.	nine groups of food items (freshwater fish, marine fish, pork, chicken, chicken eggs, leafy, non-leafy vegetables, rice and flour) and three types of human samples (human milk, maternal serum and cord serum) were collected for the analysis of pcdd/fs. results of chemical analysis revealed pcdd/fs concentrations (pg g(-1) fat) in the following ascending order: pork (0.289 pg g(-1) fat), grass carp (ctenopharyngodon idellus) (freshwater fish) (0.407), golden thread (nemipterus virgatus) (marine fi ...	2009	19535140
risk assessment of residual ddts in freshwater and marine fish cultivated around the pearl river delta, china.	six species of freshwater fish collected from 10 fishponds in shunde and zhongshan, china, four species of marine fishes collected from different mariculture farms [four in hong kong (tung lung chau, ma wan, cheung chau and kat o) and two in mainland china (daya bay and shenzhen)] together with feed (both trash fish and commercial pellets) and sediment were analyzed for ddts. total ddts in freshwater fish flesh decreased in the order of: carnivores [1742 microg/kg lipid weight (l.w.)] > herbivor ...	2010	19603131
the influence of mariculture on mercury distribution in sediments and fish around hong kong and adjacent mainland china waters.	to study the influence of mariculture on mercury (hg) speciation and distribution in sediments and cultured fish around hong kong and adjacent mainland china waters, sediment samples were collected from six mariculture sites and the corresponding reference sites, 200-300 m away from the mariculture sites. mariculture activities increased total mercury, organic matter, carbon, nitrogen and sulfur concentrations in the surface sediments underneath mariculture sites, possibly due to the accumulatio ...	2011	21075414
an outbreak of streptococcus agalactiae infection in cage-cultured golden pompano, trachinotus blochii (lacépède), in malaysia.		2012	22913387
molecular characterization of streptococcus agalactiae strains isolated from fishes in malaysia.	the aim of this study was to characterize streptococcus agalactiae strains that were isolated from fishes in malaysia using random amplified polymorphic dna (rapd) and repetitive extragenic palindromic pcr (rep-pcr) techniques.	2013	23557382
viral susceptibility, transfection and growth of spb--a fish neural progenitor cell line from the brain of snubnose pompano, trachinotus blochii (lacépède).	this study investigates the susceptibilities of the spb cell line to fish viruses including giant seaperch iridovirus (gsiv-k1), red sea bream iridovirus (rsiv-ku), grouper nervous necrosis virus (gnnv-k1), chum salmon reovirus (csv) and eel herpesvirus (hva). gsiv-k1, rsiv-ku and csv replicated well in spb cells, with a significant cytopathic effect and virus production. however, the cells were hva and gnnv refractory. to examine the ability of spb cells to stably express foreign protein, expre ...	2013	23305502

assessment of heavy metals/metalloid (as, pb, cd, ni, zn, cr, cu, mn) concentrations in edible fish species tissue in the pearl river delta (prd), china.	the major aim of this study was to investigate heavy metal content of edible fish in the prd. eleven species of fish (consisting of 711 individuals) [catfish (clarias fuscus), tilapia (oreochromis mossambicus), grass carp (ctenopharyngodon idellus), bighead carp (aristichthys nobilis), mandarin fish (siniperca kneri), snakehead (channa asiatiea), black bass (micropterus salmoides), mangrove snapper (lutjanus griseus), star snapper (lutjanu stellatus), snubnose pompano (trachinotus blochii) and o ...	2014	24239097
genetic characteristics of streptococcus dysgalactiae isolated from cage cultured cobia, rachycentron canadum (l.).	disease outbreaks occurred during 2007-2013 in taiwan with 2.5-10% mortality among the cage cultured cobia, rachycentron canadum (l.), characterized by the presence of polyserositis, pericarditis and peritonitis. the micro-organisms isolated from internal organs were gram-positive cocci. the isolates were confirmed as streptococcus dysgalactiae by a polymerase chain reaction assay that yielded the expected specific 259 bp amplicon. additionally, partial sequence of the 16s-23s rdna intergenic sp ...	2015	25087459
the effects of mariculture on heavy metal distribution in sediments and cultured fish around the pearl river delta region, south china.	thirty-six sediment samples were collected from six mariculture sites and corresponding reference sites (approximately 200-300 m away from each mariculture site) to study the effects of mariculture on heavy metal: copper (cu), zinc (zn), chromium (cr) and lead (pb) distribution in sediments and cultured fish around the pearl river delta region, south china. the mean concentrations of cu, zn, cr and pb in all mariculture sediment samples were 109, 273, 99 and 33 mg/kg, compared with 63, 209, 56 a ...	2016	26807936
