We engaged in cooperative research with fishers and stakeholders to characterize the fine-scale, spatio-temporal characteristics of spawning behavior in an aggregating marine fish (Cynoscion othonopterus: Sciaenidae) and coincident activities of its commercial fishery in the Upper Gulf of California. Approximately 1.5-1.8 million fish are harvested annually from spawning aggregations of C. otho...

and customary fishers mainly take white sharks as bycatch in gillnets, and occasionally on longlines (Duffy unpubl. data). Sport fisheries for white sharks in New Zealand are largely undeveloped and fishers often tag and release those they do catch (Mossman 1993; Wilson 2002). A protective beach meshing programme run by Dunedin City Council (DCC) operates seasonally off Brighton, St. Clair and ...

Tropical rainforest regions are urbanizing rapidly, yet the role of emerging metropolises in driving wildlife overharvesting in forests and inland waters is unknown. We present evidence of a large defaunation shadow around a rainforest metropolis. Using interviews with 392 rural fishers, we show that fishing has severely depleted a large-bodied keystone fish species, tambaqui (Colossoma macropo...
