5 years ago These 2 terms will need to be linked to the SeaDataNet sample collector category http://vocab.nerc.ac.uk/collection/L21/current/ICAT01/
Unless the community feels that there is a need for a new L21 category to distinguish fishing gears from the typical scientific sample collecting gear.

5 years ago Terms added to L05. The URIs: http://vocab.nerc.ac.uk/collection/L05/current/71/ http://vocab.nerc.ac.uk/collection/L05/current/72/ will be live within the next 24 hours. They have been mapped to the broader category ICAT01 in L21 and to the broader L05 concept http://vocab.nerc.ac.uk/collection/L05/current/64/
We have received a new request to add two types of dredge to L05: scallop dredge and queen scallop dredge. We were given the following links: https://seafish.org/gear/gear/profile/scallop-dredge and https://seafish.org/gear/gear/profile/queen-scallop-dredge
The FAO entry for fishing dredges has the following description: gears which are dragged along the bottom to catch shellfish. They consist of a mouth frame to which a holding bag constructed of metal rings or meshes is attached. There are two main type of dredges; heavy dredges towed by boats (boat dredges), and lighter ones operated by hand in shallow waters (hand dredges) (source: http://www.fao.org/fishery/geartype/104/en)
Proposed new L05 records
PrefLabel: Scallop dredges Description: Rigid structures with a chain mail collecting bag, towed on the seabed to target king scallops. Generally used by towing several dredges side by side behind the vessel (source: seafish.org).
PrefLabel: Queen scallop dredges Description: The dredges used to target queen scallops are wider and higher than a traditional scallop dredge. They do not have tooth bar across the front, instead they have either a metal grid, or tickler chains to get the scallops to lift up off the seabed and swim into the dredge. The scallops then fall back into a bag made of metal rings. Some fishermen are replacing the tickler chain and metal grid with a strip of rubber matting across the front of the dredge (source seafish.org).
