To better understand the nature of discards and their impact in ecological, socioeconomic and technical terms, the MINOUW project is running 17 case studies spread across 7 countries, including fisheries based on trawl gears, purse seines, dredges, traps, pots, nets and loglines.

Find out more about what each case study involves, and what we hope to achieve, reading the case study summaries below.
