Counterintuitive Responses of Fish Populations to Management Actions

摘要: Abstract Observed ecosystem responses to fisheries management experiments have often been either much smaller or in the opposite direction of expected based on experience population models. Examples these can be found even for some very simple experimental manipulations such as predator and prey small lakes ponds fish harvest closures. Such counter-intuitive prediction failures offer opportunities identify key processes variables that are not widely considered models used evaluate ecosystem-based policies. A common denominator case histories presented unexpected behavioral strong changes juvenile survival rates driven by competition, predation, predation risk. These factors restructured many ecosystems our examples, yet included currently ecosystem-base...
