Population dynamics of the big-belly seahorse (Hippocampus abdominalis) in south east Tasmania

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.
