Hi Jay,
There are round 700 fish species in NZ waters.
About 97% of these you would never come across in your
life time. I checked with a freind who is 7x NZ
casting champion & repairs fishing reels for a living;
he'd never heard of a croaker fish in NZ. I used to
draw fish & memorize their scientific names, but
haven't come across a Croaker fish. We have a gurnard that "barks" when you land it. But it's
nothing
like a Croaker.
Interesting "The sounds are produced by the beating
of abdominal muscles against the swim
bladder"
Maybe we could exploit the fact that the submarine
is similar to a large swim bladder.

Alan,
No it is actually a fish also
known as drums or hardheads (you made me do some research on the web: http://en.wikipedia.org/wiki/Sciaenidae
). There is also a description of how they make the
sound.
