Monitoring of the Incidental Catch of Whales and Dolphins
Monitoring
of the incidental catch of whales and dolphins is biological sampling which has been carried out on sea fishing areas of the Republic of Slovenia since 2007. The sampling is
performed monthly on fishing vessels which hunt with pelagic trawl nets.
The data is collected by the experts from the Institute, who operate as observers
on the decks of fishing vessels. The data is entered in the standardized forms
and afterwards transferred to the database.

Large Porpoises in the Vicinity of a Fishing Vessel |
|
The videotape shows a group of large
porpoises (Tursiops
truncatus) in the vicinity of the fishing
vessel. The large porpoises were attracted by the catch of the fishing vessel,
which is preparing for the loading of the catch to its deck.
Large
porpoises are predators and are at fishing events frequent observers of fish
loading maneuvers from the fishing nets. It can also happen that the fishing
vessel, by mistake or intentionally, also catches some porpoises, or that the porpoises
run into the fish catch.
