  abstract = {{T}he time series of {EU} purse seine fleet catches per unit effort ({CPUE}) of small (<10kg) and large (>=10kg) yellowfin tuna ({YFT}) from the {I}ndian {O}cean were standardized using an extension of the {D}elta-lognormal {GLMM} to three components. {T}hese components are: (i) the detection rate of schools per unit of searching time, (ii) the proportion of sets for which the targeted size category is present and (iii) the biomass of the targeted size category in the fish school. {T}he aim was to use the commercial size categories as a proxy to depict the trend in abundance for adult and juvenile {YFT} observed in free schools ({FSC}), as well as for juveniles caught under floating objects ({FOB}).},
