This paper deals with the control of an invasive species, void of market value, and acting as a space competitor for a native valuable harvested species. The paper presents a theoretical bioeconomic model describing the interacting dynamics of the two stocks. In the model, control variables are the levels of...
This paper studies the economic consequences of the invasion of a coastal fishery (Bay of Brest) by an exotic species (Crepidula fornicata) which was accidentally imported some decades ago. This species is a space competitor for the main targeted species of the fishery (Pecten maximus), and its development is a...
During the last decade, several new aquaculture species like tilapia and pangasius has appeared in significant quantities, and growth for more traditional species like shrimp and salmon continues at high rates. This has led to and will continue to lead to significant changes in the world's seafood markets. As this...
Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

This paper deals with the economic impact of an aquatic invasive alien species on a coastal shellfish
fishery. A slipper-limpet (Crepidula fornicata ) was accidentally imported some decades ago, has
established and is spreading in the bay of Saint-Brieuc (France). This exotic species is acting as a space
competitor for...
The data represent 48-state USA weather and climate data (both site and gridded), biological phenology (developmental) models, combined with photoperiod response (diapause inducing sensitivity to short daylengths). The example data sets are specific to a single insect biological control organism (a leaf beetle introduced to control purple loosestrife, an invasive...
Malawi - a country in southern Africa is endowed with vast natural resources. Among these, is Lake Malawi, the 8th and 3rd largest lake in the world and Africa respectively. It is by far the only lake in the world with highest fish species biodiversity - around a thousand. The...
The swordfish fishery is one of Hawaii's most lucrative, and also most highly regulated, fisheries. According to the United Fishing Agency (UFA) fish auction data in 2005, average swordfish (shallow-set)
revenue per trip was $76,897.03 and average tuna (deep-set) revenue per trip was $36,382.14. Swordfish trips, however, comprised of only...
Most fish stocks worldwide are not optimally exploited and are therefore are producing less in biologic and economic terms that what it could be obtained. MSY objective for all the stocks by 2015 is put forward by several countries as management target to be achieved, while other countries such as...
