Estimation of catch rate and mean weight in the exploratory Dissostichus fisheries across Divisions 58.4.1 and 58.4.2 using generalised additive models
these fisheries. Analyses of C2 catch rate and mean weight data from 2484 longline hauls conducted ... between 2003 and 2011 enabled the development of generalised additive mixed models that were then used to ... make predictions of catch rate and mean weight across fishable depths in both Divisions. Catch rates ... , with most locations within fishable depths predicted to have catch rate of less than 100 kg per 1000 ...
