Contributions to knowledge on the maturation and fertility of the common octopus "Octopus vulgaris" Cuvier, 1797 on the Portuguese coast

Year: 2003

Type: article

Abstract: The aim of the present study was to study the reproduction of the common octopus Octopus vulgaris Cuvier, 1797 at three locations on the mainland Portuguese coast. The results showed a higher occurrence of mature females in May-July and November at both Cascais and Santa Luzia, and in February and November at Viana do Castelo. Mature males were found year round. The fertility of females from Santa Luzia was higher (average of 230 000 oocytes), which could be due to this location's more favourable environmental conditions. At Cascais, the average was 140 000 oocytes, and at Viana do Castelo, 120 000. Our results could be useful in drawing up more suitable management measures for octopus Portuguese stocks.
