Turkish Journal of Zoology
The histological changes of gonads were studied in Aphanius persicus from the Barm-e-Shoor spring (south of Iran). The gonads were extracted and prepared histologically. The maturity stage of each specimen was examined according to size and weight of gonad, degree of occupation in the body cavity, the type and number of germinal cells (in testis) and follicles (in ovary). We have described 5 sexual stages for females and 4 for males. The total length and body and gonad weight of each specimen increased with increasing maturity stages. In females, the appearance of ripe oocytes was in stage IV and V …

The karyotypic and cytogenetic characteristics of southern catfish, Glyptothorax silviae Coad, 1981, was investigated for the first time by examining metaphase chromosome spreads obtained from gill epithelial and kidney cells. The diploid chromosome number of this species was 2n = 52. The karyotype consisted of 9 pairs of metacentric, 14 pairs of submetacentric, and 3 pairs of subtelocentric chromosomes. The arm number was 98. No heteromorphic sex chromosomes were cytologically detected in this catfish. Comparison of the chromosome number of this fish with that of the other members of subfamily Glyptosterninae shows that 2n = 52 may be regarded as …
