Accuracy and precision of the continuous underway fish egg sampler (CUFES) and bongo nets: a comparison of three species of temperate fish
Abstract We examine the accuracy and precision of the continuous underway fish egg sampler (CUFES) relative to bongo nets based on the catch ratio of Atlantic cod ( Gadus morhua ), American plaice ( Hippoglossoides platessoides ), and cunner ( Tautogolabrus adspersus ). We derived expectation of cat...
