Discriminación de variables ambientales que influencian la captura por unidad de esfuerzo: el caso de la pesquería de krill antártico Discrimination of environmental variables that influence the catch per unit effort: the case of the Antarctic krill fishery

Latin American Journal of Aquatic Research, 2011
Para emplear la captura por unidad de esfuerzo (CPUE) como índice de abundancia se debe realizar normalmente un proceso de estandarización que consiste en aislar desde las series de tiempo de CPUE todos aquellos efectos exógenos a las variaciones ...

CPUE-based assessments of the Greenland halibut resource using SCAA

, 2009
SCAA is used to assess the Greenland halibut resource as in Butterworth and Rademeyer (2009), but here using CPUE rather than surveys to provide indices of abundance. The approach is essentially that of an ASPM – a standard production model except that agestructure of the commercial catch is also taken into account.
