White blood cell count Gobiidae as a biomarker of ecological state in the Sevastopol Coastal Area (Black Sea)

This report outlines the research findings on White Blood Cell Count (WBC) and on the role of blood biomarkers in relation to adapting to environmental conditions and pollution in three species of Gobiidae fish: the round goby Neogobius melanostomus, the black goby Gobius Niger and the knout goby or toad goby Mesogobius batrachocephalus, caught in the bays of the coastal area of Sevastopol. We found statistically significant interspecific differences in the proportion of M. batrachocephalus and N. melanostomus segmented neutrophils. The dynamics and wide norm of the reaction of segmented neutrophils characterizes the features of physiological and biochemical processes in adapting to environmental conditions and pollution for N. melanostomus. Segmented neutrophils are largely responsible for the formation of adaptive response and ecological plasticity in Gobiidae. The studies of the white blood system Gobiidae will allow deeper study of biological, environmental, physiological and biochemical features and adaptive capabilities of different species of the family and provide effective coastal monitoring at load pollution.
