Global marine primary production constrains fisheries catches.
Primary production must constrain the amount of fish and invertebrates available to expanding fisheries; however the degree of limitation has only been demonstrated at regional scales to date. Here we show that phytoplanktonic primary production, estimated from an ocean-colour satellite (SeaWiFS), is related to global fisheries catches at the scale of Large Marine Ecosystems, while accounting f...
متن کاملGlobal marine fisheries resources: status and prospects
This paper discusses the current status of the world’s fisheries and their prospects for the future, from the perspective of the economics discipline. We focus on governance institutions within which fisheries are conducted, discussing their evolution during the post WW II period with particular emphasis on the jurisdiction extension codified by the Law of the Sea Convention in 1982. We discuss...
متن کاملTrends in GlobAl MArine Fisheries – A criTicAl view1
Trends in global marine fisheries – a critical view Abstract Individual fisheries are generally perceived as one fleet exploiting one or several target species. Their welfare then depends on the relation between the size of each fishery relative to the size of population(s) it exploits, which ‘stock assessments’ are supposed to evaluate and ‘fisheries management’ is supposed to adjust. The visi...
متن کاملBenefits of Rebuilding Global Marine Fisheries Outweigh Costs
Global marine fisheries are currently underperforming, largely due to overfishing. An analysis of global databases finds that resource rent net of subsidies from rebuilt world fisheries could increase from the current negative US$13 billion to positive US$54 billion per year, resulting in a net gain of US$600 to US$1,400 billion in present value over fifty years after rebuilding. To realize thi...
متن کاملBycatch of marine mammals in U.S. and global fisheries.
Fisheries bycatch poses a significant threat to many populations of marine mammals, but there are few published estimates of the magnitude of these catches. We estimated marine mammal bycatch in U.S. fisheries from 1990 to 1999 with data taken from the stock assessment reports required by the U.S. Marine Mammal Protection Act. The mean annual bycatch of marine mammals during this period was 621...
