Changes in the skin‐scale complex with sexual maturation in the European eel, Anguilla anguilla (L.)
Structural features of the epidermis, dermis and scales were examined in adult female Anguilla anguilla of varying sexual maturity. Advanced sexual stages were obtained by hormone injection. The dermis increased in thickness with both size and sexual development. Epidermal thickness was unrelated to...
