“…However, in order to reinforce this suggestion, it is very important to continue to feed the databank with more information from the SSV estuary and from estuaries subject to low human impact to confirm this characteristic of this species, beyond which it is important to increase information regarding others actors for use as bioindicators of trace metal pollutants, thus making fish sampling efforts more productive in terms of the advance of knowledge on the situation of the food chain and the increase in the number of potential bioindicator species [27][28][29][30][31][32][33][34][35].…”

“…NAE are sensitive non-specific indicators of mutagenic damage, they can however provide an additional tool for the understanding of the genotoxic effect and have been used by some authors in biomonitoring studies [15,26,27]. In the four species analyzed (M. americanus, M. furnieri, C. faber and P. brasiliensis) in relation to the expression of genotoxic effects, C. faber was the most responsive since it showed a more significant NAE, as well as clastogenic effects expressed with a greater frequency of micronuclei.…”

“…In the four species analyzed (M. americanus, M. furnieri, C. faber and P. brasiliensis) in relation to the expression of genotoxic effects, C. faber was the most responsive since it showed a more significant NAE, as well as clastogenic effects expressed with a greater frequency of micronuclei. In general, fish from environments subject to weak human influence have a NAE frequency range of 3-20‰ [28,27] . Arslan et al [26] observed a higher MN frequency in five fish species from water polluted by domestic and industrial sewage than in fish from relatively clean water in Aliaga Bay (Turkey) with a MN frequency ranging from15-40‰.…”

Trace elements As, Co, Fe, Hg, Se, Zn and Cr were determined in muscle tissue, gills and liver and nuclear abnormalities in erythrocytes (NAEs) were observed in 7 fish species (Chaetodipterusfaber, Paralanchurusbrasiliensis, Micropogoniasfurnieri, Achiruslineatus, Genyatremusluteus, Menticirrhus Americanos and Micropogoniasfurnieri), from two estuarine regions subject to different levels of anthropogenic impact (preserved and polluted) to provide information on contamination levels. The bioaccumulation in C. faber suggested that it should be proposed as a bioindicator of pollution in estuaries. The hydrological data: temperature, salinity and dissolved oxygen characterized the estuarine waters. A paradoxical result relating to As, Co, Fe and Zn concentrations was that, in general, these were higher in the fish species of the Cananeia estuary (a preserved area), while Hg concentrations and NAEs were higher in the species of the Santos-São Vicente estuary (SSV) (the polluted area). The bioaccumulation in tissue-organs decreased in the following order: liver>gill>muscle, with the exception of Hg that was liver>muscle with no detection in gills. Concerning the genotoxic effects, C. faber showed a more significant NAE, besides clastogenic effects, demonstrated by the greater frequency of micronuclei. Differences found between the fish species could be related to their feeding habits and to salinity. This is a contribution to making fishery efforts more profitable and enhancing the bioindicator bank.

“…Studies are carried out using various methods (assessment of water quality based on the results of chemical analysis, calculation of the integral indicator of water quality -water pollution index (WPI), as well as using the method of phytotesting) [1, 2,3]. Particular attention is paid to bioindexing and biotesting [4,5,6].…”

Assessment of the ecological state of the surface waters of the Nikitinsky fish passage channel during dredging work

Fish passage channels along the main delta watercourses serve for upstream spawning of fish and stingrays of young and adult fish back to sea, thereby preserving and multiplying the biodiversity of the ecosystems of the Caspian basin. The flickering sections of the canal-fish passage require periodic dredging. When analyzing the ecological and geochemical situation of the territory, one of the most informative objects of research is surface water. Accumulating pollutants coming from watersheds over a long period of time, soils are an indicator of the ecological condition of the territory, a kind of integral indicator of the level of pollution. As part of the study, an assessment was made of the ecotoxicological state of the surface waters of the fish passage channel during dredging in the Volga delta, the environmental toxicological status of the coastal zone of the canal was analyzed according to accepted standards, possible adverse environmental changes were predicted, and proposals were developed for a program of production ecological monitoring the nature of changes in surface water quality as a major component of the ecosystem.

“…For comparison, we also used Fulton’s condition factor (CF) because it is still widely used in fish condition studies (e.g. [35,36,37,38]), even though CF violates several key assumptions [16,18]. In particular, CF is a simplistic ratio that assumes a cubic relationship between mass and length that does not reflect fish growth patterns in nature.…”

Most ecologists and conservationists perceive parasitic infections as deleterious for the hosts. Their effects, however, depend on many factors including host body condition, parasite load and the life cycle of the parasite. More research into how multiple parasite taxa affect host body condition is required and will help us to better understand host-parasite coevolution. We used body condition indices, based on mass-length relationships, to test the effects that abundances and biomasses of six parasite taxa (five trematodes, Apatemon sp., Tylodelphys sp., Stegodexamene anguillae, Telogaster opisthorchis, Coitocaecum parvum, and the nematode Eustrongylides sp.) with different modes of transmission have on the body condition of their intermediate or final fish host, the common bully Gobiomorphus cotidianus in New Zealand. We used two alternative body condition methods, the Scaled Mass Index (SMI) and Fulton’s condition factor. General linear and hierarchical partitioning models consistently showed that fish body condition varied strongly across three lakes and seasons, and that most parasites did not have an effect on the two body condition indices. However, fish body condition showed a highly significant humpbacked relationship with the total abundance of all six parasite taxa, mostly driven by Apatemon sp. and S. anguillae, indicating that the effects of these parasites can range from positive to negative as abundance increases. Such a response was also evident in models including total parasite biomass. Our methodological comparison supports the SMI as the most robust mass-length method to examine the effects of parasitic infections on fish body condition, and suggests that linear, negative relationships between host condition and parasite load should not be assumed.
