CARDOSO, Franz; VILLEGAS, Piero  and  ESTRELLA, Carlota. Observations about the biology of Octopus mimus (Cephalopoda: Octopoda) in the Peruvian coast. Rev. peru biol. [online]. 2004, vol.11, n.1, pp.45-50. ISSN 1727-9933.

The Gould Octopus, Octopus mimus Gould, 1852 is widely distributed along the Peruvian coast and is target of an important artisanal fishery. The size-weight relationship in Ilo and Callao shows an allometric growth for both sexes. The females reach a spawning size at 14,3 cm of mantle length. That size was used to estimate a minimum weight of catch of 1 Kg. The diet was variable and it included crustaceans, mollusks, fish and echinoderms. Catches were six times higher during El Niño 19971998 than El Niño 1982-1983. The present data is compared and discussed with those of Chile.

Keywords : Octopus; Octopus mimus; taxonomy; biology; Peru.
