Gill net calibration study for the Round Island Test Fishery

It is becoming increasingly difficult to rely on multi-strand nets for the Round Island gill net test fishery. Manufacturers are not making a lot of 60 mesh multi-strand (MS60) nets anymore as the demand from industry is focussed on 90 mesh Alaska Twist (AT90) nets. Given the latter information and the low inventory of net material, we are proposing to conduct a four year study to compare the relative catchability of Fraser River Sockeye in the Round Island gill net test fishery using a MS60 versus an AT90 gill net.
