A study of steroid cells in gonads of salmon fry after hormonal treatment
The state of steroid-producing cells (SPCs) in fry pink and coho salmon was studied after treatment with sex steroid hormones in different doses and at different stages of gonadal sex differentiation. Thus, SPCs activity increased in gonads in test fish whose condition of gonads at the moment of analysis was different from the condition of gonads in control fish. High activity of SPCs was observed irrespective of whether hormonal treatment suppressed or stimulated development of sex cells fund and also irrespective of the time of SPCs investigation (during the hormonal treatment of test fish or a long period of time afterwards).
