摘要：Egg masses of the Patagonian squid Doryteuthis (Amerigo) gahi attached to giant kelp (Macrocystis pyrifera) in the Magellanic channels of the sub-Antarctic ecoregion in southern South America is documented for the first time. Of seven egg masses observed between 2008 and 2011, one was taken to the laboratory to be analysed and photographed. Comprising long transparent capsules containing eggs, the masses were strongly attached to the stipes of M. pyrifera. This macroalgae is a potentially important economic resource due to its multiple industrial uses; this study shows that it also serves an important ecological role as a spawning substrate for D. gahi.Keywords: Doryteuthis; egg masses; giant kelp; Patagonian squid; sub-Antarctic ecoregion(Published: 5 November 2014)Citation: Polar Research 2014, 33, 21636, http://dx.doi.org/10.3402/polar.v33.21636
