The number of large fish species
in Australian waters has declined by 30% in the past decade, mostly due to
excessive fishing, a new study says.
Marine ecology experts are
calling for changes to fisheries management after publication of the study by
scientists from the University of Tasmania and the University of Technology
(UTS), Sydney.
The decade-long study used data
from diving surveys by three different bodies – the Australian Institute of
Marine Science, the University of Tasmania and Reef Life Survey, a supervised citizen
science group – to compare trends in fish populations in unprotected marine
areas, protected areas that allow for some fishing, and protected areas that
prohibit fishing.
Data was collected repeatedly
from 533 sites around Australia from 2005 to 2015 for large fish species –
those bigger than 20cm in length, such as snapper, bream and parrotfish.
