Summary
Small scale fisheries (SSF) are a large component of the EU fleet. In Portugal, SSF hold great tradition and importance representing 83% of the fleet in 2017. A well-managed fishery is expected to use gears that will catch most of the available species at sizes that will not undermine fishery sustainability. Understanding the type of gears and the factors that influence their use is also vital to determine the interaction between social and ecological change. The two fundamental causes of high discards are the use of unselective fishing techniques and the failure to restrict fishing effort. Estimating discards is essential for assessing the full impact of fisheries upon fish populations and upon the ecosystem, and this was identified as one of the main shortcomings of the Common Fisheries Policy. Data on commercial fisheries discards in EU waters is scarce and the estimates have, in general, low precision. As so, discards represent an important and poorly documented source of fishing mortality, contributing to the overfishing of fish stocks. Most of the scientific research on EU discards has been focused on large-scale fisheries, assuming that SSF's discards are lower than those associated with industrial fishing. As a result, there is a lack of knowledge on many biological, environmental, socioeconomic, management and policy aspects of SSF, mainly regarding discards. The LESSisMORE project aims the identification of the most favourable locations for catching target species while reducing discards and fishing effort at the same time, which brings ecological and economic benefits. To achieve this goal we quantify discards and fishing effort; build predictive models to identify the best conditions for fishing, with low fishing effort and low discards; assess the socioeconomic impact of the decrease in fishing effort, discards and the implementation of the landing obligation; increase the value of discarded species.
