“…Again, sites 2 and 3 appeared similar with the fishes from site 1 displaying the largest reduction compared with control (site 4). This reduction in spleen somatic index is in agreement with Pulsford et al (1995) who noted a reduced spleen somatic index in goby (Zosterisessor ophiocephalus) from a polluted site. Unfortunately no significant di#erence could be seen in the pronephric somatic index.…”

“…There is growing evidence that these compounds are extremely harmful to marine and freshwater ecosystems, since they are highly persistent and bioaccumulate up aquatic food webs. This is widely documented in fish species in various brackish Mediterranean ecosystems (Pulsford et al, 1995;Focardi et al, 1998). Liver and muscle tissue are used in pollution assessments and for comparison purposes, while concentrations in gonads, like ovaries, are crucial for reproduction (Hellou et al, 1993), since "the early life stages [of biota] are more susceptible to the effects of pollution" (Kime, 1997).…”

Biological responses and contaminant levels in biological tissues were investigated in fish specimens of grass goby (Zosterisessor ophiocephalus) collected in spring 2000 in a moderately polluted brackish ecosystem, the Orbetello lagoon (southern coast of Tuscany, Italy). The complexity of harmful effects that contaminants may cause in fish over time was assessed. General condition indices (somatic liver index, and gonadal somatic index), cytochrome P450 enzymes, acetylcholinesterase activity and ovarian morphology were integrated with the content of organochlorines (OCs-hexachlorobenzene, DDTs and polychlorinated biphenyls) in liver and ovaries and p-nonylphenol (NP) and lower ethoxylate (NPE 1-2) content in muscle and ovaries as well. Samples collected from the western basin of the lagoon near the Orbetello sewage treatment plant had somatic liver index values and two P450 activities significantly higher than those collected from the same basin at the Albegna river delta and in the Ansedonia canal in the eastern basin (P < 0.05). On the other hand, while muscle content of p-NP and NPE 1-2 was significantly higher in samples from the Orbetello and Albegna river sites than in samples from the Ansedonia canal site, OC levels in liver (DDTs > PCBs > HCB) were particularly lower in samples from STP compared to levels detected in sites AC and AR. Light microscopy of ovaries revealed that although the gonads were sexually mature, the diameter of the oocytes and eggs was smaller than that commonly reported. High levels of OCs and NPs were, in fact, observed in grass goby ovaries, and the differences observed between acetylcholinesterase activities among investigated sites suggest exposure to insecticides as well. The integration of biological responses and contaminant tissue content reveals that certain areas of the lagoon are selectively impacted by various human activities and helps in distinguishing relationships between biological responses and contaminant load in the lagoon environment.

“…Accordingly, as we have previously reported for CFs, low values of both CFs and KSI observed in the Zletovska River could be associated with extremely high metal exposure in the water of that river in the time of chub sampling, as well as with probable insufficient fish nutrition (Barišić et al, ; Jordanova et al, ). Investigations on KSI are scarce compared with the other organo‐somatic indices because the removal of the kidney is a difficult procedure (Pulsford et al, ). Still, some information on pollutant effect on KSI is available.…”

Pollution with heavy metals may influence the immune system of fish, leading to impairment of their health or even increase their mortality. The fish kidney is one of the first fish organs to be affected by water contamination. Amounts of kidney macrophages (MACs), which are involved in fish immune response, as well as the qualitative and quantitative changes in the pigmented MACs in fish kidney, are used as biomarkers of pollution. Therefore, in this study, we have evaluated relative and total volumes of trunk kidney pigmented MACs, and analyzed the pigments accumulated within them. Fish were sampled from two mining impacted rivers, Kriva and Zletovska, highly contaminated with heavy metals, and from one reference river, Bregalnica, in spring and autumn of 2012. We have observed that main pigments found in kidney MACs of Vardar chub were melanin and lipofuscin/ceroid, as well as that relative volumes of MACs ranged from 0.56 to 1.68%. Moreover, the results showed that relative volumes of pigmented MACs were higher in metal contaminated rivers, especially in autumn season in the Zletovska River, concurrently with extremely high metal exposure. In addition, condition factors and kidney somatic indices were found significantly lower in the Zletovska River in both seasons, autumn and spring, possibly also as a consequence of high water pollution. Our data confirm that increase in relative volumes of pigmented MACs may serve as warning sign of potential heavy metal pollution in aquatic environment.
