ANGFA (WA) has been trying to obtain a fish collection lscence for a few
months now to no avail! Our fishries department are full of shit and keep
returning the application saying that we need to include more info bla bla
bla. So one of our members has aranged for our group to assist one of his
collegues from UWA in a project on Nightfish. The project is about the
estivation of this species. This person who has this interest in nightfish
once found one estivating, not masterbatinbg! in the mud in a dried up pond.
So the research will have something to do with that and involve collecting
specimens - which ANGFA (WA) will do.

A further project may also be going ahead with the nightfish. It will be on
the reproductive habits of this species. The project will be linked to a
grant to rehabilitate an acid affected area south of perth called Collie.
Coal mining has had a disasterous effect on the pH of the surrounding waters
in this area and it just happens that one of the people who are organising
this grant has an interest in nightfish, which are still found in the acid
affected waters.
