Circle hook size and spacing effects on the catch of pacific halibut. Leaman, B., M., Kaimmer, S., M., & Webster, R., A. 7, 2012. Paper doi abstract bibtex Joint fishing for halibut (Hippoglossus stenolepis Schmidt, 1904) and sablefish
(Anoplopoma fimbria Pallas, 1811) in Alaska in recent years has created questions
about the use of fishing effort data in the halibut stock assessment. The optimum
gear for halibut uses larger hooks and longer spacing than sablefish gear. We
conducted a randomized block fishing experiment to estimate the relative fishing
power of different hook sizes and spacings. The blocks consisted of 12 randomized
treatments, each a combination of one of four hook sizes and four hook spacings. All
possible treatments were not tested because some are not used in the fishery. Each
treatment consisted of a single 100-hook skate of gear. Primary response variables
were the weight of legal-sized halibut for commercial retention and the count of
sub-legal sized fish. The experiment was conducted in a high fish density region
in 2005 and in a lower fish density region in 2007. There was no evidence of an
interaction effect between hook size and hook spacing in either year, for either legalsized
weight or sub-legal count. Hook size had an effect on sub-legal fish counts in
both areas, with highest catches on smaller hooks, but there was evidence of a hook
size effect on legal weight in the high density area. Hook spacing had an effect on
weights and counts with higher catch seen on the longer spacings.
