1996 - 2013, North Western Inshore Fisheries and Conservation Authority (NWIFCA) Mussel Surveys

The NWIFCA conducts mussel surveys across its district in order to inform the management of this fishery. Data is collected on the percentage cover of a bed in mussel and other habitat types. The relative proportion of different size classes of mussel is also recorded. Samples are often taken for production of length frequency tables. Mussel beds are usually surveyed irregularly, with an adaptive survey strategy focusing on those beds that are very important commercially or have specific issues around their management.西北渔业与野生动物保护委员会（NWIFCA）在其管辖区域内开展贻贝资源调查，旨在为该渔业的管理提供决策支撑。调查采集的数据包含贻贝床及各类生境的覆盖百分比，同时记录不同规格等级贻贝的相对占比。研究人员通常会采集样本以编制长度频率表。贻贝床的调查多以不定期形式开展，采用自适应调查策略，重点聚焦于商业价值突出或存在特定管理难题的贻贝床。
