Line weights of constant mass (and sink rates) for Spanish-rig Patagonian toothfish longline vessels
kg weights at 40 m intervals on longlines to minimise interactions with seabirds. The weights are ... equipped with bags of rocks (4 kg, 6 kg and 8 kg) and lines with steel weights of equivalent masses. The ... purpose of the experiment was to provide vessel operators with the option of substituting steel weights ... for rock weights while remaining in compliance to the sink rates associated with the line weighting ...
