- Аннотация: Thyroid hormones (THs) are the most important regulators of coloration ontogeny in teleosts. It has been shown experimentally that alterations in the hormonal status due to prolonged treatment with a biologically active form of THs, triiodothyronine, causes changes in the development of adult pigment patterns in bilaterally symmetrical Amatitlania nigrofasciata and Poecilia wingei. Induced hyperthyroidism in experimental fishes leads to an acceleration of coloration ontogeny and an increase in the frequency of asymmetry in various elements of the melanistic pattern. The revealed dependence of the development of asymmetric pigment patterns on the activity of the thyroid axis in fishes with varying degrees of metamorphic coloration transformations offers the prospect for further experimental studies of the role of the TH-signaling pathway in the evolution of teleosts.
