Teresa C. Borges, Patricia Calixto, João Sendão 2016 (PDF)

To study the behaviour of the common octopus (Octopus vulgaris) towards the traditional amphora clay shelter-pot, the cylindrical plastic shelter-pot and the new amphora plastic shelter-pot, several experiments were performed in controlled tanks.

The results showed no particular preference towards the material of the fishing The common octopus fishery in South Portugal: a new shelter-pot ÍNDICE 133 gear; a strong preference for the traditional amphora shape; and a strong preference for the black colour. Keywords: Octopus fishery; octopus shelter-pots; octopus fishing gear; octopus behaviour.

Interesting findings. The traditional Japanese octopus pots were like amphora, but now they use something that looks like a little doghouse. Usually they're made of black plastic with a door that closes when they begin to pull the pots up.
