2018 Gear: Quantifying the Selectivity Characteristics of an Extended Link Apron using a Dredge Cover Net
Principle Investigators: Farrell Davis, Ricky Alexander, Liese Siemann
Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program
The proposed project would expand upon previous work with extended link aprons which has shown great potential in reducing fish bycatch. CFF will conduct four research trips to evaluate the selectivity characteristics of one-way vertical extended link apron using a dredge cover net. Two dredges, one equipped with a standard apron and another with an extended link apron, will be towed simultaneously. A cover net will be affixed to both dredges, alternating between tows with and without cover nets. Catches from both dredges and both cover nets will be sorted, enumerated, and measured.
