Survival experiments revealed the diverse Damage and mortality rates were also lower using SDredge (1.3% and 1.0% of the totalĬatches, respectively) than using DDredge (4.0% and 2.8% of the total catches). Bycatch rates were lower for SDredge (13.5% in number and 6.3% in weight) than for DDredge (46.0% Taxa that were caught, 73.4% belonged to the target species, 22.1% to commercially undersized target species and 4.5% toīycatch species. A total of 15 fishing surveys (60 tows) were performed using two types of dredges (“DDredge” targetingĭonax trunculus and “SDredge” targeting Spisula solida and Chamelea gallina). Quantify the bycatch and discards, estimate damage and mortality, and propose management measures to minimize discardsĪnd mortality.
