Juvenile pale octopus (Octopus pallidus) growth

The aim of this study was to assess how individual size-at-hatching and food consumption influences the growth of Octopus pallidus hatchlings reared under simulated seasonal temperature regimes in Tasmania.

Statement
Three O. pallidus females with egg clutches of approximately 200 eggs each were collected from waters in northwestern Tasmania, Australia on 15 February 2005. Females were housed at Tasmanian Aquaculture and Fisheries Institute (TAFI) in Hobart, until hatching. The experiment ran from 1 June to 23 September 2005 (114 days). A total of 64 octopuses were used and divided randomly into two treatments of 32 individuals. The two treatments replicated the local seasonal water temperatures of northwestern Tasmania. The treatments were spring/summer (14–18oC) and summer/ autumn (18–14oC). The octopuses were weighed individually every 2 weeks to 0.001 g wet weight before feeding, allowing for progressive monitoring of the growth of each individual. Further information on methodology, is available in the published paper.
