Trawling and longlining in the Namibian hake industry [PDF]
, 2002 Two hake species are caught off the coast of Namibia. These are Merluccious capensis and Merluccius paradoxus, and they are not distinguished between in catches . Two fishing fleets harvest hake, these are trawlers and longliners. In this study, the focus has been on the biological and economic characteristics of two different fishing methods.

Revealing the Global Longline Fleet with Satellite Radar
Scientific Reports, 2022 Because many vessels use the Automatic Identification System (AIS) to broadcast GPS positions, recent advances in satellite technology have enabled us to map global fishing activity. Understanding of human activity at sea, however, is limited because an unknown number of vessels do not broadcast AIS.

Hauling Speed of Tuna Longline-I
NIPPON SUISAN GAKKAISHI, 1971 The present report showed the outline of hauling speed and the influence of catch and accident on it observable in the records collected from the hauling work of the 10 strings of tuna longline about at 155°E near the Equator conducted by the Choho-maru (266 gross tons), And the results obtained were summarized as follows: 1.

A Novel Longline That Can Be Used By a Single Crew in the Aegean Sea: Solo Longline
Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries, 2020 This short paper presents an innovation on the use of a bottom longline with only a single crew on a fishing boat in the Aegean Sea. The mainline was 0.80 mm in diameter and 75 m in length, with branch lines of 0.45 mm in diameter and 70 cm in length. Distance between two adjacent branch lines was 7 m.

A review of cetacean interactions with longline gear
J. Cetacean Res. Manage., 2023 Fishery-cetacean interactions, including those with longline gear, give rise to economic, ecological and social concerns. This paper reviews problems resulting from cetacean-longline interactions, considers potential strategies to reduce interactions and identifies research priorities and approaches.

Visualizing the Food-Web Effects of Fishing for Tunas in the Pacific Ocean
Ecology and Society, 2004 We use food-web models to develop visualizations to compare and evaluate the interactions of tuna fisheries with their supporting food webs in the eastern tropical Pacific (ETP) and the central north Pacific (CNP) Oceans.

Complex movements, philopatry and expanded depth range of a severely threatened pelagic shark, the oceanic whitetip (Carcharhinus longimanus) in the western North Atlantic. [PDF]
PLoS ONE, 2013 Oceanic whitetip sharks (Carcharhinus longimanus) have recently been targeted for conservation in the western North Atlantic following severe declines in abundance. Pop-up satellite archival tags were applied to 11 mature oceanic whitetips (10 females, 1
