All of this has substantially changed not only stock assessments (through the impact of novel technology on catch rates overtime), but also the way fisheries are managed. In short, as technological innovations creep into a sector, assessment and management have to adapt (Marchal et al. 2006)....
In between these extremes were the majority of exploited reef fishes for which one would expect some combination of attraction and production affected by reef ecological setting and overall stock abundance. (Implicit in the argument by the fisheries scientists was the assumption that fishing pressure ...

Working standards were always newly prepared from the stock solution (1000 ppm, Fluka, Switzerland) by serial dilution. The concentration of heavy metal in the unknown sample was obtained by extrapolation from the calibration curve. Acid blank was run along with the sample regularly which was ...
We focused particularly on the western Baltic cod fisheries (hereafter WB cod), given it represents a data-rich stock within the management advisory context, and for which many relevant aspects could be explored in more details. Most importantly, however, is the fact that there has been an ...
the environmental impacts of aquatic food production reach beyond GHG emissions.Capture fisheries are responsible for overexploitation of fish stock and habitat degradation,particularly of benthic ecosystems,as well as marine pollution in the of lost and discarded fishing nets,among other factorsFAO,2024c...
Finally, stay tuned for the first episode of The Healthy Skeptic audio podcast, coming up next week. I’ll be interviewing Stephan Guyenet, Ph.D, on the subject of obesity and weight regulation. Stephan is a senior fellow at the University of Washington studying the neurobiology of body fat...
Fishermen might not have letters like M.S. or Ph.D. after their names, but as keen observers on the water over the course of a lifetime, they are invaluable sources of scientific information. If you ask fishermen what they look for to predict changes in fish stock health, they will tel...
