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，为该渔业的管理工作提供科学决策支撑。调查采集的数据涵盖贻贝床及其他生境类型的盖度百分比，同时记录不同规格等级贻贝的相对占比。研究人员常采集样本以制作体长频率表。贻贝床通常采用不定期调查方式，并采用适应性调查策略，重点关注那些商业价值极高或在管理层面存在特定问题的贻贝床。
