“…Finally, in rainbow trout, higher concentrations were found in plasma, followed by fins, gut content, muscle, and skin mucus, demonstrating inter-species variations. Also recently, Gozdowska et al [ 55 ] used skin samples of three-spined sticklebacks ( Gasterosteus aculeatus ) from the southern Baltic Sea to simultaneously investigate if melatonin, AFMK (N1-acetyl-N2-formyl-5-methoxykynuramine; biologically active metabolite of melatonin), and cortisol would create a local stress response system in fish, similarly to what is known to occur in mammals. Oxidative stress in the individuals was then induced by exposing them to potassium dichromate.…”

“…Multiple studies have also reported positive correlations between mucus and plasma cortisol concentrations [ 53 , 54 , 55 , 56 ]. When assessing cortisol concentrations in plasma, mucus, gut contents, and muscle of sea bass ( Dicentrarchus labrax ) before and after stressful situations, Simontacchi et al [ 53 ] reported clear and significant correlations between plasma and the other evaluated matrices, with concentrations 10–30-fold higher concentrations detected in plasma.…”

Cortisol is the main glucocorticoid released during stress responses in most fish and has been employed to investigate different stressors, including organic pollutants. This review discusses shifts in cortisol concentrations and examines different matrix sampling methods (invasive vs. minimally or non-invasive) and the main analytical cortisol determination techniques (immunoassays and liquid chromatography-tandem mass spectrometry). Assessments on organic pollutant exposure in fish and associated adverse effects are also discussed. Studies in this regard may aid in identifying organic pollutant toxicological modes of action, mechanistic response, toxicokinetics, and toxicodynamics, as well as pollution sources and associated health risks in fish, ultimately aiding in the development of effective management strategies to mitigate the impacts of organic pollutants on fish populations and their associated ecosystems.

“…It would be interesting to study whether crowding could altogether halt sex change or eventually help the sex-changing female to revert to its original female state. Notably, it is hypothesized that dominant males in social groups of protogynous species are responsible for inhibiting the socially induced sex change of subordinate females through their aggressive behavior, and the release from this high stress (i.e., drop in cortisol) could trigger the sex change of the alpha female, which would, in turn, keep the cortisol levels of the rest of the females elevated (Perry and Grober, 2003;Goikoetxea et al, 2017;Iger et al, 1995;Overli et al, 1999;Hattori et al, 2009;Yamaguchi et al, 2010;Hayashi et al, 2010;Iwata et al, 2012;Nozu and Nakamura, 2015;Goikoetxea et al, 2021;Gozdowska et al, 2022). We also found a significant increase in the occurrence of stage-1 sex change fish, immediately (within 7 days) after the removal of the males from the group, which largely supports the abovementioned cortisol-based sex change mechanisms.…”

The gonadal sexual fate of vertebrates is either defined by genetics or environment, or a combination of both factors. Interestingly, in sequential hermaphroditism, the animal can undergo natural sex changes from female-to-male, male-to-female, and bidirectional way throughout their lives. This change exhibits the process which shifts between oogenesis and spermatogenesis and is regarded as an ideal instance of sexual plasticity. To develop the experimental model for studying the sexual plasticity of protogynous fish, the social conditions that induce sex changes were defined in wrasse, Pseudolabrus sieboldi. When six females were kept together in a tank, the largest female became a male, whereas a similar conversion did not occur when only two females were present in a tank. A semi-gonadectomy analysis developed in the present study verified the direct relationship between gonadal sex and body coloration. In P. sieboldi, the sex change is controlled by the relative body size of an individual within a group, rather than by absolute body size. When six females were kept in smaller sized tanks, delayed sex change or unchanged individuals was observed. Overall, more than 90% of the largest females demonstrated sex change after being housed with five smaller females in different sizes of tanks ranging from 80 to 500 L. Furthermore, the experiment using a transparent barrier suggested that visual stimuli are one of the major cues to initiate sex change. Our findings on the laboratory conditions leading to the initiation of sex change in wrasse suggest the usefulness of this species as a model organism for comparative studies in molecular, cellular, and physiological mechanisms of sexual plasticity, as well as on social and reproductive behaviors.

“…Furthermore, the skin, which is directly exposed to environmental stressors, is a site of the synthesis of biologically active components involved in the stress response (Kulczykowska, 2019). These components of the so-called cutaneous stress response system may affect melanin dispersion in melanophores (Kulczykowska et al, 2018;Gozdowska et al, 2022;Pomianowski et al, 2023). Now, a brief reminder: various types of chromatophores are involved in the pigmentation of teleosts; among them are the most universal black or brown melanophores primarily located in the dermis, although they can also be observed in the epidermis (Fujii, 2000).…”

“…Lately, we conducted an analysis of the dispersion of melanin in melanophores after a short-term exposure of three-spined stickleback to oxidative stress (Gozdowska et al, 2022). To evoke oxidative stress, we have used a potassium dichromate solution (K 2 Cr 2 O 7 ) well identified as an anthropogenic water pollutant that induces oxidative stress in aquatic organisms, including fish (Velma et al, 2009;Ko et al, 2019).…”

The diverse and changing pigmentation of the skin allows fish to adapt to environmental conditions for survival and communication with conspecifics. However, various physical and chemical environmental factors, including pollutants, affect fish coloration. Therefore, the implementation of an analysis of skin pigmentation has been considered in fish well-being and ecotoxicological studies. A physiological color change is achieved by the motility of melanin-containing organelles: they aggregate into the perikaryon or disperse throughout the cytoplasm of melanophores in response to various stimuli. In our study, we addressed the issue of implementing the analysis of pigment dispersion in melanophores in stickleback skin to assess the response of fish to oxidative stress. We examined pigment dispersion in day and night skin samples collected from the dorsal, lateral and ventral regions. The degree of pigment dispersion we assessed by the melanophore index. The total number of melanophores counted in the defined skin area was significantly higher in the night samples than in the day samples. Only in day samples of dorsal skin we observed the significant changes in pigment dispersion after exposure to stress: melanin was predominantly in the aggregated state. In the night samples, we did not report any response to stress in any part of the skin. Examination of pigment dispersion in melanophores in stickleback skin can be useful for assessing the welfare of fish and detecting toxic agents in the environment, but under specified conditions: in sticklebacks, it is analysis of dorsal skin during the day.
