Microsatellite DNA markers and morphometrics reveal a complex population structure in a merobenthic octopus species (Octopus maorum) in south-east Australia and New Zealand

Five polymorphic microsatellite loci were developed and then used to assess the population genetic structure of a commercially harvested merobenthic octopus species (Octopus maorum) in south-east Australian and New Zealand (NZ) waters. Beak and stylet morphometrics were also used to assess population differentiation in conjunction with the genetic data.

Statement: Octopuses were collected from five sites: north-east Tasmania (NE), south-west Tasmania (SW), the Eaglehawk Bay aggregation (EHB) in south-east Tasmania, South Australia (SA) and New Zealand (NZ). Octopuses were collected as bycatch from rock lobster fishers (at depths between 10 and 40 m) from all sites except EHB, where they were collected from the commercial octopus fishery (at depths between 1 and 3 m). All specimens were frozen prior to dissection. A tissue sample was taken from either the arm or mantle muscle of each individual and preserved in 70–80% ethanol. Stylets were air dried for 24 h prior to dry storage in vials, and beaks were preserved in 70% ethanol. A total of 13 morphometric characteristics from the beaks and stylets were measured from the same specimens used in the genetic analyses: stylet weight (SW), anterior stylet length (ASL), total stylet length (TSL), beak height upper and lower (BHU and BHL), beak width upper and lower (BWU and BWL), beak length upper and lower (BLU and BLL), hood length upper and lower (HLU and HLL) and rostrum length upper and lower. Length measurements were made with digital callipers with a precision of 0.01 mm, and stylet weight was measured to 0.1 mg. Details on microsatellite isolation, screening and data analysis, can be obtained from the published paper.
