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.

在塔斯马尼亚地区，针对海马种群开展了水肺潜水（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，调查频次为先亚月度、后调整为月度；2004/5年度起至2007年，在东海岸及德文特河区域每年开展两次调查。
此外，还开展了标记重捕法（Mark-recapture）研究，以估算种群规模及生活史参数。
