Dear MARMAM community,

We are delighted to announce the publication of our paper in Estuarine,
Coastal and Shelf Science
Pardalou A, Adamidou A, Tsikliras A.C. (2022) Dolphin depredation and
damage accumulation on different set nets in the northeastern Mediterranean
Sea. Estuar. Coast. Shelf Sci. doi: 10.1016/j.ecss.2022.107866

Abstract
Small-scale fisheries represent an economically marginalized sector, that
struggles to balance operational costs and profit from catches. Economic
revenues from catches have declined due to overfishing, and additional
costs may jeopardise the sustainability of the sector. In Greece, reported
net damage from interaction with marine megafauna, especially the
bottlenose dolphin (Tursiops truncatus) is a common occurrence for many
coastal areas, where small-scale fisheries operate. A seasonal experimental
trial took place during 2016–2017 in the northern Aegean Sea, in an area
where large actively swimming marine organisms other than dolphins were
lacking. Three gangs of different panels of net (mixed gill nets and
trammel nets) were deployed in three different depth zones. For each gang,
we recorded the number, size, and position of holes on each net, and
assessed overall damage. Multifactor analysis was used to identify possible
links between fishing practices and damage intensity. Results showed a
correlation between reduced net damage by dolphins with larger mesh sizes
and increasing depth. In the case of small mesh sizes, one should seek a
combination of solutions, as changes in deployment depths alone, do not
seem to be adequate for the depth ranges studied. The adoption of larger
than 22 mm mesh size is proposed for all set nets, to increase net
selectivity and decrease accumulated damage. Fishers should focus on
adjusting, substituting or even ceasing specific fishing tactics to have
the lowest possible economic loss, whereas fisheries scientists, managers
and policy makers must monitor and offer guidance for this transition.
