Study on the fishing performance of an alternative tubular-type pot for the common octopus, Octopus minor, in Korean coastal waters
We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...

متن کاملInfiltrated plaques resulting from an injury caused by the common octopus (Octopus vulgaris): a case report
Several species of octopus are considered venomous due to toxins present in the glands connected to their “beak”, which may be associated with hunt and kill of prey. Herein, we report an accident involving a common octopus (Octopus vulgaris) that injured an instructor during a practical biology lesson and provoked an inflamed infiltrated plaque on the hand of the victim. The lesion was present ...
متن کاملMultiple paternity in the common octopus Octopus vulgaris (Cuvier, 1797), as revealed by microsatellite DNA analysis
Two microsatellite DNA markers developed for the common octopus, Octopus vulgaris, were used to determine genotypes of four brooding female octopuses and 11 embryos sampled from their respective clutches, in order to confirm the multiple paternity hypothesis within this species. Two well-known reproductive behavioural patterns are apparently conflicting in mating outcome: the often-observed mul...
متن کاملCharacterization of the skin mucus in the common octopus Octopus vulgaris (Cuvier) reared paralarvae
The Octopus vulgaris farming is impaired by the high mortality of the paralarvae during the first month of life. Several factors have been investigated in this regard, but no data exist on the body surface mucus, which represents the interface with the outside environment. This study included morphometric analysis and glycoconjugates characterization of skin mucus in reared Octopus vulgaris par...
