Economic Models of Recreational and Commercial Fishing and Their Impact on the Great Lakes Ecosystem
… the intended effects. The second paper models commercial fish harvest on the Illinois and Mississippi Rivers. A potential control strategy for Asian carp, an invasive species, is to pay commercial fishermen a subsidy to harvest Asian carp. We estimate a model of the supply of fish and use it to …

Human Error in Commercial Fishing Vessel Accidents: An Investigation Using the Human Factors Analysis and Classification System
<p>The commercial fishing industry is frequently described as one of the most hazardous occupations in the United States. The objective, to maximize the catch, is routinely challenged by a variety of elements due to the environment, the vessel, the crew, and several external considerations and how …

From lime kilns to art galleries: a historical anthropogeography of the Maine Coast City of Rockland
… steel as the favored material for shipbuilding. Commercial fishing and fish processing followed lime as the main industry. Dominance by fishing was not nearly as long-lived as lime production; in Rockland, as elsewhere in New England, the collapse of commercial fishing took a great toll beginning …

Examining the interrelationship between competition law, the allocation of fishing rights, and transformation in South Africa’s fishing industry
The fishing industry in South Africa is distinguished by the various species of fish that can be caught and by the scale of operations required to undertake the various type of fishing activities. Furthermore, the industry is broadly divided into the commercial sector and the small-scale sector. …

The historical exploitation of chondrichthyans in False Bay, South Africa and assessment of their conservation status
Commercial fishing in False Bay, South Africa, began in the 1600s. Today chondrichthyans are regularly taken in multiple fisheries throughout the Bay. Using time series data and life history information I assessed the vulnerability of chondrichthyans to exploitation in False Bay. Extensive time …

Bycatch of the Lake Pontchartrain Basin inshore shrimp fishery and its effect on two sea catfish species: the gafftopsail catfish (Bagre marinus) and the hardhead catfish (Ariopsis felis)
<p>In Lake Pontchartrain Basin, commercial fishing in estuarine habitats impacts many non-target species collected as bycatch. I investigated the bycatch assemblages collected by commercial vessels and compared these to assemblages collected by typical fishery-independent methods. I compared …

Capsizing of ships : static and dynamic analysis of wind effect and cost implications
Capsizing of small vessels, such as commercial fishing vessels, is a frequent event. This phenomenon is generally associated with the combined action of storm seas, inadequate design parameter regulations, and dangerous operational procedures. In contrast, the capsizing of large ships is rare, but …
