Dear Carl
The reality of this is that most of these fish species have been known
to occur here for a very long time.. But recently, a database mapping
system (redmap) has been initiated by a group of (environmentalists?) to
encourage everybody to report sightings, catches etc of fish. This
encouragement has resulted in a huge increase of reported data, however
most of the results are not camparable with any previous recording
database/method/recording system and hence, the results are not
comparable with an established benchmark.
It appears that new info is construed as evidence of changed
environmental conditions without proper scientific evaluation. In
reality, most of this new information has been known by local fishers
but not officially recorded. Around the traps, there is a belief that
there is a hidden agenda behind much of this, probably a push for
research funding to support the interests of a minority group.

Dear B-A,
It will be interesting to see what changes in the pelagic species seen off our
east coast, if this trend continues.

A worrying trend.
