Metabarcoding gillnets to assess unaccounted catch depredation or escape [PDF]

Gillnets are often retrieved with holes in the netting, which means some animals escape or are depredated unseen, but with some mortality. To effectively manage fisheries around the world,

Mitigating discard mortality from dusky flathead Platycephalus fuscus gillnets [PDF]
Diseases of Aquatic Organisms, 2009 The mortalities and contributing parameters were estimated for key species discarded during commercial gillnetting (80 mm mesh) targeting dusky flathead Platycephalus fuscus in a southeastern Australian estuary. Bycatches (1470 individuals from 16 species over 11 deployments) were assessed for their immediate mortalities onboard the gillnetter, before ...
