In Tasmania, SCUBA surveys of seahorses populations were conducted. Intensive surveys were conducted in 2000 to 2004 in the Derwent River around Hobart (submonthly & then monthly) and twice yearly surveys from 2004/5 on east coast and Derwent River, until 2007. Mark-recapture studies were done to estimate population size, and life history parameters.
SCUBA surveys and mark-recapture of seahorse populations in Sydney Harbour using visible implant fluorescent elastomer.
Population dynamics of weedy seadragons (Phyllopteryx taeniolatus) and spiny pipehorses (Solegnathus spinosissimus) in south east Tasmania
Limited SCUBA surveys of weedy seadragons at Kingston, Blackman's Bay & Bicheno and spiny pipehorses at Simpson's Point, Bruny Island. Mark-recapture study of approximately 40 seadragons and 10 spiny pipehorses.
The data was collected from 2 years of field sampling from the commerical octopus (Octopus pallidus) fishery in NW Tasmania in Bass Strait. The data consists of morphological, reproductive and ageing information.
