Demersal longlines with integrated weight: a preliminary assessment of sink rates, fish catch success and operational effects
at 0.3 m/s to 15 m depth. Sink rates can be achieved by adding external weights to lines or by using ... g/m 75 g/m and 100 g/m integrated weight averaged 0.11 m/s, 0.227 m/s, 0.272 m/s, 0.317 m/s and ... 0.353 m/s, respectively. The longline with externally attached weights sank at 0.32 m/s. IW longlines ... sank instantly, reaching 1 m depth in 6-9 s whereas unweighted lines took >20 s to reach this depth ...
