Abstract(s)
Em Abril de 1992, foi registado pela primeira vez, a ocorrência de uma postura natural de Loligo forbesii nos Açores. A postura encontrava-se dentro de uma armadilha de PVC colocada a 25-30 m. utilizada para a captura de polvo. Foram contados 20 cordões ovígeros com 39-52 embriões, todos no mesmo estádio de desenvolvimento. Após 28 dias de incubação em cativeiro os embriões degeneraram. Esta observação é a primeira confirmação que Loligo forbesii se reproduz nas costas dos Açores.
ABSTRACT: Natural laid eggs from Loligo forbesii have been encountered for the first time in Azores. The spawn was found inside a PVC trap set for 0ctopus, at 25-30 m depth, during April 1992, and it consisted of twenty strands with 39 to 52 embryos, all in the same stage. The embryos degenerated after 28 days in aquarium. This finding is the first confirmation that Loligo forbesii spawns around the coasts of the Azores islands.
