Sisters Of The Coast Shark Lagoon.epub

Its not only humans that enjoy this coastline every where there are warnings that sharks frequent these waters. Intrepid as we are and avoiding the high risk times of dawn and dusk we have swam and snorkelled most days.
When government agencies set fishing quotas and sustainable catches for industrial trawlers they use data from just the last few decades of ocean surveys and fish catch monitoring. But when historical data from analogue sources, and in particular fishing boat logs and the journals of fishers, are included in the statistics, the decline of stocks of sharks and of coastal and even deep sea fish is above 90% for each species by number (McClenachan et al. 2012). Historic records indicate quantities of creatures in the sea in abundance that have not been seen for decades. It is a similar story for land birds and mammals, and here the documentary record of sharp declines in numbers is greater.Footnote 1
