A common catadromic fish is eel (Anguillidae), and it spawns in sea water.

Thanks to all for responding to me about the question posed below.  I now know 
that "catadromous" eels from all over the world exhibit the behaviour that I 
was looking for.

BTW, responses were received from au, ca, uk, ie, za, and us.  My daughter and 
I were really impressed with the "power of the net"!

Thanks again,  Lee

I know this thread has run its course, and the school assignment was
successfully negotiated. Whenever the word "catadromous" comes up,
everyone answers "eels." Are any other fishes catadromous, or do the
anguillidae have a lock on it?

>anguillidae have a lock on it?

Depends. Some fish are obligate saltwater spawners, but are in other respects 
euryhaline. Some species of mullet, for example, will move a long way up tidal 
rivers, into pretty much fresh water, but must spawn at sea. Flounder do this 
too, juveniles will appear in virtually fresh water, but must return to the 
sea to spawn. Whether you want to define this as catadromy or not comes down 
to semantics. They don't perform the strictly partitioned salt/fresh/salt 
lifestyle of some eels, but they do migrate to sea to spawn. A lot of 
estuarine species are a bit tricky this way.

On the other hand, I seem to recall that there are some Clupeids which are 
truly catadromous, in the strict sense.

But don't quote me on it :-)

I think you'll find they don't.

Here in the Pacific Northwest US, all of the _Salmo_ spp. engage in
some upstream migration into freshwater spawning habitat. The chum and
pink salmon (O. keta and O. gorbuscha, respectively) exhibit the
shortest upriver migration and in some cases spawn in pretty darn
brackish water. But when it comes to anadromy - as opposed to
catadromy - salmon are the usual example.

 sorry.....Most salmon swim "up" stream to spawn. not to the ocean...

OK, I've been holding out, but I studied some fishes years back for
thier potential aquaculture use.  I'm not remembering real well, but I
think that the Australian barrimundi (snook family?) is catadromous. 
Perhaps one of our Aussie friends could verify this.

I spent several years in Palau in the Western Pacific, studying freshwater fish
that live in streams on this beautiful set of islands. Palau has a number of
gobies and eleotrids that are strictly freshwater as adults but return to the
sea to spawn.  Both of these fish families are of marine origin.   Greg Bright

Ack, what a geek, following up my own post, where I said:

Of course, I meant Oncorhynchus, not Salmo. *Bonk*

How about eels? They spawn in the Sargasso sea, and migrate to
freshwater when mature. Sorry, don't know the genus/species.

Salmon feed in the sea but spawn in fresh water!

What you are looking for is the eel which spawns in the Saragosa Sea.

I have recently been informed that (2) two of my company’s fishing vessels have 
qualified for the Fishing Capacity Reduction Initiative (FCRI). I am interested
in selling the vessels for a substantially discounted price. Either would make a
fine research vessel or could be used for education, training, humanitarian, 
safety or law enforcement purposes. If you have any interest in either or both 
of these vessels, please contact me at your earliest convenience to discuss price
and specifics.

If I have been following correctly, we have:
Gobies [Paulau]
Eels
Birrimundi/Snook [Australia]
correct? A very fascinating thread!
