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 کاملPredation Risk within Fishing Gear and Implications for South Australian Rock Lobster Fisheries
Depredation of southern rock lobster (Jasus edwardsii) within fishing gear by the Maori octopus (Pinnoctopus cordiformis) has economic and ecological impacts on valuable fisheries in South Australia. In addition, depredation rates can be highly variable resulting in uncertainties for the fishery. We examined how in-pot lobster predation was influenced by factors such as lobster size and sex, se...
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...
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 ...
