Tourism impact on stream fish measured with an ecological and a behavioural indicator. The cellular composition of the testes varied during the reproductive and parental care periods. The female laid adherent eggs over the spawning surface in a line of around 10 eggs and then the male passed over fertilizing them Table 1. Testes of MP were composed of 50% of spermatozoa, whereas spermatogonia type B and spermatocytes were predominant in the subsequent parental phases. Emballage de qualité .
