A re-analysis of the squid jig CPUE data
, 2006 The catch per unit effort (CPUE) indices from the squid jig fishery have to date been expressed in terms of catch per man-hour (Roel, 1998). Industry has for many years questioned the use of man-hours as the unit of effort since it is alleged that the information contained in the database regarding the number of hours fished is unreliable.

An evaluation of the effects of blue crab (Callinectes sapidus) behavior on the efficacy of crab pots as a tool for estimating population abundance [PDF]
, 2011 Crab traps have been used extensively in studies on the population dynamics of blue crabs to provide estimates of catch per unit of effort; however, these estimates have been determined without adequate consideration of escape rates.

Some news approaches for standardizing tropical purse seiners CPUEs
, 2014 Indices of CPUE are presented for skipjack tuna (Katsuwonus pelamis) for the Indian Ocean over the period 1980-2013. The analysis was initiated under the framework of the E.U. research project CECOFAD, whose objectives are to enhance our understanding of fishing effort units and improve the accuracy of purse-seine CPUE estimates.

An ecological analysis of rockfish (Sebastes spp.) assemblages in the North Pacific Ocean along broad-scale environmental gradients [PDF]
, 2008 Environmental variability affects the distributions of most marine fish species. In this analysis, assemblages of rockfish (Sebastes spp.) species were defined on the basis of similarities in their distributions along environmental gradients.
