“…In the Mondego estuary and adjacent coastal water the CF is similar at all ages, and it is, also, similar to those found by Kleinkauf et al (2004), also for P. flesus. The relationship of weight and length remain constant throughout P. flesus different age groups, and the condition factor also remains constant along the species different age groups.…”

“…Regarding HSI, there is some discrepancy in the literature concerning the interpretation of the decrease or increase in HSI values in fish (Güngördü et al, 2012). Some authors pointed out that exposure to pollutants may cause liver dysfunction capable of interfering with normal development, increasing HSI values (Kleinkauf et al, 2004). Though, exposure to PAHs or heavy metals results in a decrease of HSI values (Yang and Baumann, 2006).…”

“…HSI and the CF can give important information on the physiological state of the fish. P. flesus general health can be indicative of their reproductive potential and the fitness of their offspring (Kleinkauf et al, 2004). Regarding HSI, there is some discrepancy in the literature concerning the interpretation of the decrease or increase in HSI values in fish (Güngördü et al, 2012).…”

“…Furthermore, PCBs and HCB exposure to humans occurs mainly by environmental contamination of food products (Ulbrich and Stahlmann, 2004), highlighting the importance of knowing if the consumed fish is appropriated for human intake and if fish size is relevant for risks associated with consumption. P. flesus is a widely studied species regarding PCBs (Goerke and Weber, 2001;Ferreira et al, 2004), but HCB was rarely addressed (Kleinkauf et al, 2004). Regarding PCBs some studies were performed in wild animals (Ferreira et al, 2004), but many studies were performed in laboratory (Grinwis et al, 2000;Goerke and Weber, 2001).…”

h i g h l i g h t sPlatichthys flesus muscle, liver and gills were analysed for PCBs and HCB. P. flesus was analysed along its lifespan, liver presented the highest concentration. P. flesus HCB concentration increased in the 3 tissues along the species lifespan. P. flesus PCB concentration decreased in the 3 tissues along the species lifespan. P. flesus is considered safe for human intake, regarding PCBs and HCB. a r t i c l e i n f o t r a c tPolychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) are organic contaminants that tend to accumulate in fish. Estuaries are exposed to high anthropogenic activities, therefore tending to accumulate more contaminants than the adjacent coastal waters. Platichthys flesus, a fish with high economic value, was analysed for PCBs and HCB along its different age groups, in liver, gills, gonads and muscle. Younger fishes were caught in the estuary, whereas older fishes were caught in the adjacent coastal waters and acquired at Figueira da Foz Regional Office of Docapesca-Portos e Lotas, SA. Both contaminants concentrations follow the pattern: liver > gills > muscle. Hepatosomatic index had the lowest values in younger fishes and the highest values in older fishes. Condition factor values remain stable with age. Younger fishes had higher PCBs concentrations than the older fishes. In opposition HCB was only detected in fish from 3+ to 5+ and its concentration tended to increase with age. Overall P. flesus is considered safe for human intake.

“…The finding that HSI was positively correlated to VTG concentrations has been noted before in male flounders from the estuary of the River Mersey (Kleinkauf, Connor, Swarbreck, Levene, Walker, Johnson, & Leah, 2004a). One would fully expect to find this relationship in females, as the liver is the organ where the VTG is made and it would be expected to increase in weight as it expands protein production and takes on board the necessary precursors.…”

The Deepwater Horizon oil spill released millions of barrels of crude oil into the northern Gulf of Mexico, much of which remains associated with sediments and can have continuing impacts on biota. Juvenile southern flounder (Paralichthys lethostigma) were exposed for 28 d in the laboratory under controlled conditions to reference and Deepwater Horizon oil-contaminated sediments collected from coastal Louisiana to assess the impacts on an ecologically and commercially important benthic fish. The measured polycyclic aromatic hydrocarbon (PAH) concentrations in the sediments ranged from 0.25 mg/kg to 3940 mg/kg suite of 50 PAH analytes (tPAH50). Mortality increased with both concentration and duration of exposure. Exposed flounder length and weight was lower compared to controls after 28 d of exposure to the sediments with the highest PAH concentration, but condition factor was significantly higher in these fish compared with all other treatments. Histopathological analyses showed increased occurrence of gill abnormalities, including telangiectasis, epithelial proliferation, and fused lamellae in flounder exposed to sediments with the highest tPAH50 concentrations. In addition, hepatic vascular congestion and macrovesicular vacuolation were observed in flounder exposed to the more contaminated sediments. These data suggest that chronic exposure to field collected oil-contaminated sediments results in a variety of sublethal impacts to a benthic fish, with implications for long-term recovery from oil spills.
