| Popis: | Addressing the uncertainties in fishing activities, the CEDER project examines the use of observer reports, landings, e-logbooks, VMS and GPS tracks, and fishery-specific information. Such information was assessed in order to provide more accurate and timelier data on effort, catches, discards, and/or landings. This document contains CEDER¿s Project Implementation Plan for policy makers, as well as expected benefits for government, industry, and science. The CEDER consortium advocates the use of GPS data at 15 minute intervals for scientific purposes. Among these are improved spatial planning and a new fishing effort measure, the actual effort while fishing, which can be inferred from vessel behaviour. The correlation between catch and effort can be used as an indicator for inspectors, but one cannot reliably guess catches from effort. VMS and logbook data can be matched using rule-bases systems, leading to higher data quality and better use of quota. Furthermore, if fishing mortality were known in near real time, then the integration of current year fishing mortality into management plans would yield benefits for stock recovery. The full realisation of such benefits requires a re-appraisal of the 15% TAC revision rule. The CEDER consortium insists that any roll-out of the ERS e-logbook must be properly enforced, and that the e-logbook cannot by itself replace observer reports. Finally, estimating discards may be feasible in selected fisheries, but additional means such as gear sensors may be required in order to get more reliable data in the general case.
