Electronic monitoring (EM) systems hold promise for the future collection of fishery-dependent data, either to supplement human at-sea observers or replace them. Several pilot studies have been conducted on EM in the New England groundfish fleet, though there are still on the water operational and shore-side protocols to further test...
Indicators of the economic performance of fishing vessels are frequently computed in many countries. Usually, measures of economic performance are based on the return on capital invested. However, several measures of capital value exist, according to the economic information available. In this paper, we use different types of information to...
This paper compares two methods for collecting data concerning professional fishing fleets economic performance : use of preexisting bookkeeping databases and ad hoc field surveys of fishers. Each method has its pros and cons and, for practical reasons, it may be necessary to make use of both. Such a feature...

The Australian Harvest Strategy Policy requires that maximum economic yield (MEY) be the target in all Commonwealth managed fisheries. For multispecies fisheries, unlike single species fisheries, the optimal yield is not independent of the optimal yield of the companion species (i.e. those species with which it is caught). In fisheries...
Discard rates in marine fisheries have been estimated at more than 80% for some individual fisheries, with an average global discard rate of 8%. Discarding of catch can be problematic for three main reasons: (1) in the absence of accurate and precise discards estimates, unreliable catch data distort estimation of...
This study evaluated the potential impact of global fish trade on local food prices and potential food security and associated adaptation by analyzing a locally-collected time series of disaggregated coral reef fish prices by types of fish that differed in their market chain linkages- ranging from local to international markets....
A Fishery Gross Margin (FGM) model has been used, as a cost-effective and practical alternative to more complex economic modelling, to inform the development of structured TACC decision rules as part of the formal harvest strategy adopted for the South Australian Pipi (donax Deltiodes) fishery since 2012.
The primary economic...
Lake Chad is an important fish supply centre in the semi-arid zone of West Africa. Processed Fish Trade (PFT) has catered neighbouring countries for a long time. However, Fresh Fish Trade (FFT) boomed due to severe droughts between 1970 and 1994, by which the PFT main fish species were replaced...
