One of the most serious problems facing fisheries managers is how to improve estimates of the distortion (‘fouling’) of commercial landings data resulting from misreporting in all its various forms. Data fouling (legal or illegal) drives a wedge between what is caught and killed at sea, and what is landed and reported to the regulator. This can obscure the true state of the stock causing it to appear healthier than it is, resulting in quotas being set too high. Informed by our survey of the… Expand

Estimating illegal and unreported catches from marine ecosystems: a basis for change
To evaluate the impacts of fishing on marine ecosystems, the total extraction of fish must be known. Putting a figure on total extraction entails the difficult task of estimating, in addition toExpand
Fisheries assessment: what can be learned from interviewing resource users?
TLDR
The range of information available to coastal Newfoundland fishers was identified, to see if it could be quantified, and to explore its potential for reconstructing trends within fisheries, describing ways to access the large reservoir of information held by fishers and the use of several cross-checks to identify consistent patterns.

Food for Thought ITQs and the economics of high-grading
Individual Transferable Quota (ITQ) are now used as a management tool in many fisheries. ITQ permit an individual the freedom to allocate resources so as to maximize net return within an individualExpand
Discarding of Small Redfish in the Shrimp Fishery off Port au Choix, Newfoundland, 1976-80
TLDR
Although the quantities of small redfish discarded by shrimp-fishing vessels may have been visibly alarming, the analysis indicated that recruitment to the exploitable stock would not be seriously affected by the discarding practices evident in 1976-80. Expand
On Catch Discarding in Fisheries
This paper examines the economics of catch discarding in fisheries. To study this issue a simple dynamic fisheries model is constructed. On the basis of this model it is demonstrated that in aExpand
The Newfoundland Cod Stock Collapse: A Review and Analysis of Social Factors
In 1992, the once abundant cod stocks off the coast of Newfoundland collapsed and a moratorium was placed upon fishing them. This paper provides a review of a range of social and political factorsExpand
Quota-Induced Discarding in Heterogeneous Fisheries
Abstract Individual quota (IQ) programs are a promising and increasingly common means of regulating fisheries. This paper examines how profit maximizing fishers respond to different types of IQExpand
State of the World’s Fisheries
▪ Abstract The total world catch from marine and freshwater wild stocks has peaked and may be slightly declining. There appear to be few significant resources to be developed, and the majority of theExpand
Changes over time of the size structure in an exploited shelf fish community
Abstract After a long decline that began in the 1960s, the great fisheries of Newfoundland collapsed, and since 1992 a moratorium has applied to most stocks from Labrador to the U.S. border. ColdExpand
Optimal Levels for Canada's Pacific Halibut Catch
The exclusion from U.S. waters since 1981 has greatly reduced the harvest potential for Canada's Pacific halibut fleet, making it particularly important that halibut resources in the Canadian zone beExpand
