Time-series of ecological and exploitation indicators collected from 19 ecosystems were
analysed to investigate w hether there have been tem poral trends in the status offish comm
unities. Using linear and non-linear statistical m ethods, trends are reported for six indicators
(m ean length offish in the com m unity, m ean lifespan, proportion of predatory fish, total
biomass of surveyed species, mean trophic level of landings, and inverse fishing pressure),
and the redundancy of these indicators across ecosystems is evaluated. The expected …
