Record #186044:

Autoliners and seabird by-catch: do line setters increase the sink rate of integrated weight longlines? / G. Robertson, and 4 others.

Title: Autoliners and seabird by-catch: do line setters increase the sink rate of integrated weight longlines? / G. Robertson, and 4 others.
Author(s): Robertson, G.
Date: 2008.
In: CCAMLR Science. (2008.), Vol. 15 (2008)
Abstract: Presents results of trial conducted in Ross Sea to determine effectiveness of line setters with integrated weight of 50 g m⁻¹ lead core (IW longlines) in deterring seabirds by expediting gear sink rates in Patagonian toothfish fishery. Sink rates of longlines set with and without line setter were identical, including in first few metres of water column where seabird interactions are likely to be most intense. Longlines deployed with line setter entered water several metres closer to stern of vessel and commenced sinking sooner, thus increasing slightly (<0.5 m) depth of longlines for given distances astern. However, increase in depth is minor and unlikely to result in substantial reductions in interactions between longlines and seabirds in Kerguelen and Crozet fisheries, where IW longlines are currently in use as by-catch mitigation measure.
