The target tow length is 1 kilometer which is tracked using an Olex marine charting system. Vessel crew, DFO science staff and a contracted at sea observer work together to perform required tasks and collect all relevant data. Catch from each tow is separated by species, weighed and counted. Length frequency data is collected on select groundfish and crab species and detailed morphometric data is collected on each lobster. PARAMETERS COLLECTED: Set information and profile - includes set date, time depth and location Catch summary - weight and number caught of each species Length Freqeuncies - completed for up to 100 fish for selected species Lobster Morphological Data -…
