Falklands Squid – A Fisheries Management Success Story
A suite of conservation measures overturned a negative trend in squid abundance in the 1990s, turning this into a stable fishery with total annual catches ranging between 60,000 and 80,000 tonnes over the last three years. Most of these species have short life cycles with completely new generations joining the fishery every year. The annual turnover, together with climatic variability, results in high abundance fluctuations that make squid fisheries notoriously difficult to manage and risky for fishing companies and their production chains. >click to read< During seasons, the stock biomass of squid remaining is estimated by depletion models, which are continually updated with mandatory daily reports of catch and effort from trawlers. >click to read< 14:45
Squid: Coming to Life – How a cephalopod is born, in stunning microscopy footage
Produced by the evolutionary and developmental biologist Nipam Patel in his Patel Lab at the University of California, Berkeley, Squid: Coming to Life literally puts squid and cuttlefish development under the microscope. With a sparkling soundtrack and stunning microscopy footage, the short video shows the cephalopods transforming from embryos (when they develop in egg capsules) to hatchlings that emerge with the resplendent, colour-shifting skin they use for communication and camouflage. click here to watch the video 09:35
