Spatial surplus production modeling of Atlantic tunas and billfish

Ecological Applications, 2011
We formulate and simulation-test a spatial surplus production model that provides a basis with which to undertake multispecies, multi-area, stock assessment. Movement between areas is parameterized using a simple gravity model that includes a "residency" parameter that determines the degree of stock mixing among areas.

Social and economic perspective on recreational billfish fisheries

Marine and Freshwater Research, 2003
At the Second International Billfish Symposium in Kona, it was reported that little was known about the social and economic aspects of recreational billfish fisheries. There was plenty of background, some good questions, but few answers. There had been little history of social science involvement in fisheries management at the time and even less in ...

Historical perspective of global billfish stock assessment

Marine and Freshwater Research, 2003
In spite of the substantial increase in information on billfish over the last decade, especially in the landing and catch per unit effort data, statistics for some of the commercial and recreational fisheries, basic biological information on billfish such as on growth, maturation, catch at age, and sex ratio by size, is still insufficient for the ...

Present State of Billfish Larval Taxonomy

1974
Billfishes are important both in the sport and tuna longline fisheries. Despite some research on the early life history many problems still remain to be examined. This report summarizes recent research on the identification of the larvae.
