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.

在塔斯马尼亚州，研究人员开展了海马种群的水肺潜水（SCUBA）调查。2000年至2004年，在霍巴特周边的德文特河开展了密集调查，调查频次初期为亚月度，后调整为月度；2004/2005年度起，在东海岸与德文特河开展年度两次的调查，直至2007年。此外还开展了标记重捕研究，以估算种群规模及生活史参数。
