Potential detection of illegal fishing by passive acoustic telemetry

Designing marine fishery reserves using passive acoustic telemetry

Passive acoustic telemetry has been used for many years by fisheries and wildlife biologists to elucidate a number of life-history parameters and to examine the ecological requirements of targeted populations (White and Garrott, 1990). The technology has evolved so that tags are now smaller and battery lives are longer, thus increasing the amount of data acquired and available to the manager or...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

Estimating the Worldwide Extent of Illegal Fishing

Illegal and unreported fishing contributes to overexploitation of fish stocks and is a hindrance to the recovery of fish populations and ecosystems. This study is the first to undertake a world-wide analysis of illegal and unreported fishing. Reviewing the situation in 54 countries and on the high seas, we estimate that lower and upper estimates of the total value of current illegal and unrepor...

Individual Transferable Quota Markets Under Illegal Fishing

The presence of violations and the need for enforcement of tradable property rights systems in fisheries has not receiving much attention in the literature. The theoretical promise of property rights-based fisheries is to achieve a given total allowable catch with a maximum social benefit. One of the assumption for that result is that the system is in perfect compliance. The incidents of noncom...
