In fish, one of the strongest impact factors is the chemical pollution of habitats. In an attempt to assess the consequences of heavy pollution of fresh waters for resident fishes, we studied Kamchatkan charr, which undergo paedomorphosis in the case of isolation in streams of volcanic areas contaminated with heavy metals. Experiments were carried out on the resistance of charr to metal mixtures during normal development and in six experimental groups with therapeutically altered intensity of metabolism and the secretory activity of thyroid gland. Water from volcanically contaminated streams was found to be lethally toxic for embryos and early juveniles of unadapted charr. The success of acclimation to toxic exposure was correlated with an increase in thyroid status. In experiments, the group with significantly elevated thyroid status showed a significant decrease in mortality and attenuation of oxidative stress in solutions of heavy metals. Under natural conditions, hyperthyroidism provokes a redistribution of the charr’s organism resources from somatic growth and morphological differentiation to stress counteracting and accelerated maturation, which is necessary for the long-term survival of the population under conditions of increased risk of individual mortality. Our experiments highlight the role of thyroid hormones in the rapid response to habitat pollution and the subsequent adaptation of fish populations to chronic deterioration.</p>","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138630128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data on allometric variability in plastic traits of this species are first reported. It has been proven that the most traits antlered sculpin are susceptible to variation in positive allometry (head proportions and fin sizes), while negative allometry can be observed only in several traits (the head length, the length of upper preopercular spine, and the maximum height of occipital ridge). A range of traits unsuscepyible to allometry of orbit diameter, distance from the orbit posterior edge and the occipital ridge posterior edge, predorsal distance, base length of pectoral fin, and length of caudal peduncle are revealed.

If the hybrids between the kundscha and the northern dolly varden could be previously observed only in the Utkholok River in the northwest of the peninsula, the mass hybridization between these species have occurred in two more nearby rivers, the Kvachina and Snatolveem Rivers since 2009. A microsatellite analysis has shown that hybrid specimens are characterized by intermediate values for allelic diversity, when compared to that in the representatives of parental species, while the mean expected heterozygosity values for hybrids are higher than that in Dolly Varden and kundscha fish. The analysis results for maternal inheritance in hybrid specimens from the Kvachina River coincide with that obtained in the surveys previously performed in the Utkholok River. Thus, the same haplotype specific for the kundscha fish was revealed in all the hybrid specimens, which can indicate that the hybrids originate from kundscha females and Dolly Varden males. The appearance and coloration of kundscha × northern dolly varden hybrids in the Kvachina and Snatolveem Rivers are similar to that in the specimens in the Utkholok River. Rather similar chacteristics of hybrid specimens in all three rivers can give reason to consider that a mechanism of their occurrence in the Kvachina and Snatolveem Rivers is simalr to that in the Utkholok River, since the kundscha eggs are inseminated by the Dolly Varden dwarf males. The increased local biological production of rivers due to increased sizes of spawning stocks of pink salmon <i>Oncorhynchus</i> <i>gorbuscha</i> along with large-scale climate changes in the North Pacific are considered as a possible cause of disturbances of isolation between species. It is quite probable that these two factors have contributed to improving the environmental conditions for fattening the Dolly Varden fish in the freshwater phase of their life cycle and, as a resultl of this process, increasing the number of Dolly Varden male fish matuaring in the river.</p>","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":"40 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138629935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
