“…This is in accordance with Facey et al [15] and Yang & Baumann [23] who showed that fish condition factor and tissuesomatic indices are sensitive parameters to adverse environmental affects and can be considered general health indicators in fish. The differences and specificity of alterations in haematological parameters were also shown to depend on disease duration and fish species [24,25].…”

Abstract:The investigation was carried out to ascertain the cause of mass mortalities in European perch (Perca fluviatilis L.) in NorthLithuanian rivers in 2008 that reached a maximum in mid-autumn at a water temperature of 6ºC. Marked changes were detected in morphophysiological parameters (spleen-, gill-, liver-and heart-somatic indices), which corresponded to changes in haematological parameters (leukocyte count was significantly elevated or reduced) of the infected fish. The viable bacterial counts in the gill, liver and kidney of infected live fish samples ranged from 2.3±0.3 x 10 3 to 6.3±0.4 x 10 3 c.f.u./g. The BOX-PCR fingerprinting technique was used for characterization and identification of the isolated bacterial strains from liver and kidney of infected perch. The bacterial isolates were identified by sequence analysis of the 16S rRNA gene. Pathogenic Aeromonas salmonicida subsp. salmonicida has been identified as a possible causative agent of the observed mortality in European perch.

“…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). Accordingly, our results show lower values of HSI with higher concentration of PCBs.…”

“…But, these results may be interpreted with caution, because multiple factors, other than contaminants, can cause changes in the liver size (Yang and Baumann, 2006). Among these factors can be included sampling season, nutrition or disease (Yang and Baumann, 2006). HCB was only detected in mature individuals, therefore did not interfere in HSI of younger fish.…”

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.

“…Thus, the amount PAHs metabolite (shown in fluorescence intensity) was increased with exposure time and PAHs concentration. The results found in this study is in agreement with the studies of Yang & Baumann (2005), Aas & Goksoyr (1998), and Aas et al (2000), they found that the fluorescence intensity in exposed fish was increased with exposure time and PAHs concentration compared to those in the control. Figure 3 and 4 show that EROD activity in exposed fish was increased with exposure time and PAHs concentration.…”

The aim of this study was to evaluate the efficiency of fluorescence intensity measurement of PAH metabolites in fish bile (by Fixed Wavelength Fluorescence, FF) to study and assess PAHs contamination in aquatic organism. Nile tilapia (Oreochromis niloticus) was exposed to benzene, fluorene, anthracene, chrysene, and benzo[a]pyrene at non-lethal concentrations. The results showed that the fluorescence intensity and EROD activity were significantly increased with increase in exposure times and PAH concentrations. Moreover, the results of both methods had significantly positive relation. The maximum values were reached in 16 day after exposure. Thus, fluorescence intensity measurement by FF technique could be used as a potential tool for environmental study in the case of PAHs contamination in aquatic environment.
