Backyard Aquaponics
A place to discuss aquaponics

Paid a visit to the Port Stephens Fisheries research Centre today. Thought i'd share afew pics.

I assume they were doing the mullaway in saltwater tanks Worms....

Did you happen to ask what sort of salinity and temperature, what they were feeding them etc??

and more

Mullaway can live in either Rup!(well to lower levels of salt)
Spent eons catching them in the swan river and down here in the ocean.
Nice fish a bit soft though!!

and more....all brackish/salt water stuff.

Either it is a very big Blackarse(type of fish not swearing)snapper.
or I have lost my sight!hehehe
C1

this was pretty fancy....culturing individual species of algae to feed to particular types of invertebrae

Geez, good bit of spying! Thanks.

Theres alot of different experiments happening at this place with uni student and scientist looking folk wandering around.

They trial all sorts of feed to achieve an optimum converion ratio, just about all the fish are fed mainly pellets...not much life enrichments happening for them, more like life manipulation.

They are getting kingfish, mullaway and snapper to spawn around double the natural frequency. collect eggs and hatch them...grow the out and sell them to commercial operators. I think they also release stock back into the wild.

Adults are sourced from the wild regularly to maintain genetic diversity.

Water is pumped from adjacent marine estuary when needed and effulent (fish waste water) is cycled through a series of algae pond, into a mangrove pond before returning to the estuary

cool,nice pics

Did you make the tower?

Should be able to see something that big on google!
