Abstract

Small-scale fisheries have a high
socioeconomic importance for local communities. Therefore, ensuring the
sustainability of fisheries resources would contribute for the socioeconomic development
of fisheries communities. In this study, traps produced from plastic waste
recycle materials which can be used in fishing of economically valued whelks (Hexaplex trunculus and Bolinus brandaris) that are used as
natural bait in angling and longline fishing were investigated. These traps in
different sizes were examined at the depths of 3-8 m in the Urla coasts of
Izmir Bay, Turkey. The soaking times of traps were between 10-48 hours. The
same amounts of baits (Sardina pilchardus)
were equally placed in all traps. Catch per unit efforts (CPUE) of traps were
calculated between 7-34 individuals/trap per day. The experimented traps were
found successful for whelks fishing. Traps yield high quality and economically
valued catches, related with restricted bycatch and low impact on habitat.
Therefore, these traps can be suggested as alternative fishing gears designed
for trap fisheries for whelks. This paper provides valuable knowledge for
fisheries managers and decision makers to ensure the sustainability of local
fisheries resources and small-scale fisheries.
