No presente trabalho, discute-se o processo de inversão sexual numa espécie de peixe teleósteo do litoral rochoso, o mero Epinephelus marginatus (Lowe, 1834). Em face da literatura disponível alguns aspectos mais relevantes da etologia reprodutiva de E. marginatus como sejam as agregações reprodutivas e os locais de reprodução são debatidos. Foram amostrados 60 exemplares adultos, capturados na costa sul da ilha Terceira (Açores), aos quais se procedeu à sexagem com vista a inferir da estabilidade de uma população residente em termos de sex-ratio.
ABSTRACT: In this paper we discuss the sex inversion process of a teleost fish from rocky shores, the dusky grouper Epinephelus marginatus Lowe, 1834. According to the available literature, some of the most relevant aspects of E. marginatus reproductive ethology, such as reproductive aggregations and reproduction sites, are debated. A sample of 60 adult specimens, captured in the south coast of Terceira island (Azores), was performed to obtain data of their sexual state in order to infer the eventual sex-ratio stability of a resident population.
