| Abstract |
The collection of catch composition data during inspections at sea by EU Member States occurs under the framework of joint deployment plans (JDP). It is known as “the last haul” (LH) programme and has been a fundamental tool in allowing the estimation of discards and the derivation of indicators of compliance with the landing obligation (LO). During sea inspections, measures of quantities of fish below and above the minimum conservation reference size and grade categories of the legal-size catch are used to derive estimates of discards. The methods to estimate discards assume that the relative catch composition (discard ratios) obtained with the data collected during LH inspections reflects the true catch composition of the fleet segment operating with the same gear and mesh size and in that area. The comparison between these discard ratios and with what is reported in fishers’ logbook is then used to estimate the discard component. The background of the LH programme, the methodologies for deriving discard ratios using LH data and the statistical analysis of the data are explained in this chapter. |
