NSW North Coast Shark Meshing Trial Report

Report period: 8 Feb – 7 Mar 2017

Over 8 Feb–7 Mar 2017 nets were deployed on 24–25 days at five beaches and each checked 19–35 times (Table 1). The contractors are required to check the mesh nets twice a day, but if the weather or bar conditions prevent safe access, then fewer checks are made.
