Table 1. Maturity development gonad stage (males and females) for the Brazilian snapper Lutjanus alexandrei. Data in parentheses represent the range of values for the gonad weight and gonadosomatic index. Maturity StagesMicroscopic characteristic of testisMicroscopic characteristic of ovariesImmatureSpermatocytes in early leptotenic, zygotenic and pactenic phases (0.1 - 1 g, GSI = 0.01- 0.42)Abundance of previtellogenic oocytes, no yolked oocytes and no atresia. (0.1 - 1 g, GSI = 0.1 - 0.45)MaturingSpermatocytes in metaphase I e II. Abundance of spermatids and some rare spermatozoans (1.0 - 2.7 g, GSI = 1.0 - 1.5)Vitellogenic oocytes present and high abundance of previtellogenic oocytes, no hydrated oocytes. (1.0 - 3.0 g, GSI = 1.0 - 1,7)MatureAll spermatids phase and high presence of spermatozoans. (3.0 - 6.8 g, GSI= 1.8 - 2.2)All major of oocytes in protein and lipid vitellogenesis, and rare hydrated oocytes. (3.0 - 7.4 g, GSI = 1.8 - 2.2)SpawningEmptying of spermatogenic and still have many spermatozoans. (7.0 - 12.3 g, GSI = 2.0 - 2.5)Hydrated oocytes and rare newly post-ovulatory follicles. (8.0 - 19.4 g, GSI = 2.0 - 2.7)SpawnedRare of spermatozoans in vas deferens. (6.1 - 7.2 g, GSI = 1.0 - 1.4)POF abundance; little hydrated oocytes. (6.7 - 9.4 g, GSI = 1.4 - 1.9)RestingDisorganization in spermatogenics tubules and may empty spaces between them. (0.9 - 1.3 g, GSI = 0.5 - 0.92)α- atresia and β- atresia, no vitellogenic oocytes. Previtellogenic oocytes abundance in atresia. (1.0 - 1.6 g, GSI = 0.5 - 0.96)
