RANDALL ARAUZ (PRETOMA) EXPLAINS THE IMPORTANCE OF REGIONAL COLLABORATION FOR MIGRATORY SHARKS
|
Many pelagic and coastal-pelagic species in the Eastern Tropical Pacific migrate throughout the region at different times of the year. A comprehensive regional management plan must include adequate protection for key species at particular sites or at moments during the year when they are particularly vulnerable. It is difficult to follow a shark for a long period of time, so tags are used to determine their routes. The choice of tags depends very much on the size and behaviour of the species involved.
| The information obtained from the different tags used in these studies will show us how the different populations migrate throughout the region, and whether there exist physical corridors along which the migrations occur. By placing temperature and depth sensors on the tags, it is also possible to understand their diving behaviour and relate this to vulnerability from different fishing gear. |
