Dynamic Simulation of Pelagic Longline Retrieval

Journal of Ocean University of China, 2019
To improve fishing gear efficiency, it is important to understand the interactions among sea current, fishing vessel, line hauler, and catches during pelagic longline gear retrieval. In this study, fishing gear configuration parameters, operational parameters, and 3D ocean current data were collected from Indian Ocean.

Dynamics of a mussel longline system

Aquacultural Engineering, 2003
Abstract The equations of the three dimensional motion of a submerged mussel longline system are formulated using Kane's formalism. The line is modelled using lumped masses and tension-only springs including structural damping. The mussel culture is modelled as lumped masses attached to the main line.

How fast do demersal longlines sink?

Fisheries Research, 2003
Abstract Longlines that sink fast reduce the time available to seabirds to attack baited hooks and are important in efforts to minimise seabird by-catch in longline fisheries. We measured sink rates in still seawater of longlines commonly used in the world’s demersal fisheries. Lines with integrated weight (lead cores) sank two to three times faster (

Estimating Abundance from Longline Catches

Journal of the Fisheries Research Board of Canada, 1960
The various factors that enter into the catch of fish by a baited longline are combined into equations that permit using the information afforded by the catches to compute linear estimates of abundance, providing that all rates can be estimated reasonably accurately, and assuming they are linear.

Putting Longline Bycatch of Sea Turtles into Perspective

Conservation Biology, 2006
Abstract:  Although some sea turtle populations are showing encouraging signs of recovery, others continue to decline. Reversing population declines requires an understanding of the primary factor(s) that underlie this persistent demographic trend.

Shark interactions in pelagic longline fisheries

Marine Policy, 2008
Substantial ecological, economic and social problems result from shark interactions in pelagic longline fisheries. Improved understanding of industry attitudes and practices towards shark interactions assists with managing these problems. Information on fisher knowledge and new strategies for shark avoidance may benefit sharks and fishers.
