Survey of the extent of Macrocystis pyrifera beds in the vicinity of the Mercury Passage, east coast of Tasmania, 1965

A research program jointly conducted by Alginates (Australia) P/L and C.S.I.R.O. Division of Fisheries and Oceanography was set up to investigate the relationship between kelp: Macrocystis pyrifera (Linnaeus) C. Agardh 1820 and crayfish larvae. Alginates (Australia) P/L, based at Louisville in the Mercury Passage, were harvesting kelp at this time. This study was initiated to address concerns regarding the effect of harvesting on crayfish stocks.

The survey results are taken from an unpublished interim report presenting the results of the work at that stage (1965).

Apparently an aerial survey was used to determine stock distributions although this is not specified in the report.

由澳大利亚海藻酸盐有限公司（Alginates (Australia) P/L）与澳大利亚联邦科学与工业研究组织（C.S.I.R.O.）渔业与海洋学分部联合开展的一项研究计划，旨在探究巨藻（Macrocystis pyrifera (Linnaeus) C. Agardh 1820）与螯虾幼体之间的相互关系。当时，总部位于水星航道（Mercury Passage）路易斯维尔的澳大利亚海藻酸盐有限公司正开展巨藻采收业务。本研究的发起初衷，正是为了回应有关巨藻采收作业对螯虾种群影响的担忧。

本次调查的数据源自一份未公开的中期报告，该报告呈现了1965年该研究阶段的工作成果。

尽管报告中未明确说明，但据推测，本次调查采用了航空勘测手段以确定螯虾种群的分布情况。
