Com este trabalho pretendeu-se contribuir para a investigação dos padrões de movimentação da espécie Coryphoblennius galeríta (Bíenniidae), através da análise do padrão de ocupação das poças de maré, tendo o estudo decorrido na costa portuguesa no litoral rochoso da costa do Estoril. Neste estudo, que decorreu durante o período reprodutor da espécie, pretendeu-se avaliar a existência de fidelidade, a curto e a ...
The agonistic and reproductive behaviour of Gobius cobitis (Pisces: Gobiidae)are described based on observations of fishes kept in captivity. It is argued that some features of agonistic and reproductive behaviour of this species share many functional similarities with thoes of other taxa of benthic fish, while others seem to be convergent traits typical of fishes with male parental care. The behaviour of the l...
Data are presented on the embryonic and larval development of Gobius cobitis (Pisces: Gobiidae). Embryonic development lasts from 15 days at 15°C to 17 days at 18°C. Larval development takes 37–44 days. Larvae begin to settle on the bottom at 1·3–1·4 cm total length. After five and a half months juveniles are about 5·5 cm total length.
Coryphoblennius galerita at three sites on the Portuguese coast breeds from February/March to September/October.
