Rezumat: The aim of the paper was to study the influence of triploid state at rainbow trout on the development of the sexual glands and to study the degree of sterility of the gonads. Triploid state was induced by thermic shock at 5-10 minutes from wet fecundation. The eggs were introduced in a warm water bath at 28-30 °C, for 5-10 minutes. Triploid state was assessed by measuring erythrocyte size and karyotype. The degree of sterility of the individuals was established by histologic study of the genital organs at females and males. The sterility degree is manifested different from total absence of the gonads to the presence of asymmetric developed gonads and even gonads apparently normal. Tripod individuals that have presented testicles, they have a lysed cytoplasm in the cells, seminal epithelia is present, is noticed the absence of sperm from membrane and different dystrophic processes.
