Comparison of juvenile salmon catch in Cantrawl 250 and LFS 7742 mid-water trawl nets / E.D. Anderson, T.B. Zubkowski, and J.R. King. : Fs97-6/3306E-PDF
"In October 2018, a mid-water trawl gear comparison study was completed in the Strait of Georgia on the FV Sea Crest using Cantrawl 250 and LFS 7742 nets. Captured juvenile salmon abundance, biomass and size were used as metrics to test for differences in net catchability and selectivity. After 16 net adjustments tows, the following net protocols were recommended: an adjustable setback of 17 links plus hammer lock at the surface, and 36 links at depth; two floats attached to the headrope at the surface on the wingtips, and no floats at depth; and two chain clumps, one attached to each of lower wingtips on all tows. In 32 additional tows, abundance, biomass, and fork length of juvenile salmon showed no significant differences when standardized by swept volume"--Abstract, page iv.
