WAMSI Node 4.2.1a - Bioregional level assessments based on fishery dependent and/or fishery independent data - Leschenault Estuary

The Leschenault Estuary was divided into four regions; the apex, upper, middle and lower regions. Within each region four sites were sampled seasonally (except the middle region where there were four additional crab potting sites) over two years (total of 8 sampling occasions). At each site, sampling of fish was conducted using seine nets with length and weight of all collected fish measured. In addition, water temperature, salinity, dissolved oxygen were measured at each site. The aim of the study is to develop cost-effective strategies for monitoring the fish community.

莱谢诺特河口（Leschenault Estuary）被划分为四个区域，依次为河口顶端区、上游区、中游区与下游区。在为期两年的采样周期内，各区域均设置4个采样点开展季节性采样，其中中游区额外增设4个蟹笼采样点，累计完成8次采样任务。在每个采样点，采用围网（seine net）进行鱼类采样，并对捕获的全部鱼类开展体长与体质量测量；此外，同步测定各采样点的水温、盐度与溶解氧含量。本研究旨在构建适用于鱼类群落监测的低成本高效策略。
