Silver Perch- Breeding Pair?
A pair of Silver Perch of breeding age where sourced from MPGFish today and introduced to Tank 4 (T4). Polyculture- Trout and Silver Perch in the one tank.
T4 contained the graded Trout of medium size which have almost caught up to the graded large Trout. These will be combined with T1, large Trout in a couple of weeks. We see no issue with the Trout and Silver Perch cohabitating. This is a significant step leading to our first attempts at producing our own fingerlings- more information as Spring approaches. If you are a member of Aquaculture @ Wadalba Blog please add your comments. Photos to follow.

Feed and Clean 26/6/05
All fish thriving. Testing Silver Perch to move from dust/crumble to specific Silver Perch food- 1mm pellet.
Stimulating Bass with Blood Worm- found fish NOT excited by pellets?
Trout gorging themselves and growing rapidly. Have order Trout feed, will hopefully pick-up this week.
Siphoned sump and tanks T3-5 to remove faeces etc.
The 'big' clean has made it easy to ensure best conditions for all fish.
Tidied new cupboard and stored Datalogger, chemicals etc.

NSW Aquaculture Peak Body
NSW Aquaculture Peak Body
The meeting to consider the formation of an aquaculture peak body for NSW took place at the NSW Fisheries Port Stephens Facility on Saturday the 25th June at 10.00 am.
This is a crucial time for aquaculture in NSW. The aquaculture industry in NSW needs a “voice” to promote what is the sensible use of natural resources.
Land based aquaculture is still in its infancy due to a lack of incentives , and the excess of “red tape”. Much of this is directly due to the public perception of aquaculture and what constitutes “sustainable industry”. The P.B. needs to urgently address these and other issues.
There are already a lot of good people involved in the aquaculture industry in NSW.

Total Clean
We have developed a set of instructions to clean the recirculation system. Student tested the instructions today.
Full Clean and Maintenance.
· Turn off all Shut Off Valves from Tanks 1-5
· Pump will drain the sump storing additional water in all Tanks. *Be careful that Tanks do not overflow.
· When water falls below the ‘Sump to Pump’ outlet turn pump off. Do not run pump dry.
· Siphon fish faeces and excess food from the bottom of Tanks 1-5 to a bucket/s. Use this water to water Chrysanthemums (good nutrient value for plants).
· Remove the Riser from Tank 1 (large Trout) and use the hose spray with town water to completely rinse and clean riser. * Be careful to not spill contents of Riser when taking it out of tank. Rub and remove any algae from the Riser.
· Use the Riser from Tank 1 to replace the Riser in Tank 2 (small fingerling Silver Perch) so as not to allow fingerlings to enter drain pipe. * Be careful to not spill contents of Riser when taking it out of tank.
· Use the hose spray with town water to completely rinse and clean riser. Replace Riser in Tank 1
· Remove the Riser from Tank 3, then Tank 4, then Tank 5 and use the hose spray with town water to completely rinse and clean risers. * Be careful to not spill contents of Riser when taking it out of Tank. Rub and remove any algae from the Riser.
· Turn Off the Sump to Pump valve
· Turn the handle on the filter to Close. This will prevent the filter water emptying from the Filter Basket.
· Remove the screw lid from the Filter Basket and empty and wash the basket with hose spray and town water. Replace basket after checking ‘O’ ring.
· Lay the pool filter hose across floor from Sump to outside roller door and down the side of the ARC.
· Remove Sump Drain Cap and balance pool hose in mouse of Sump Drain.
· Open the Sump Drain Valve and drain sump.
· Use town water and hose spray to ensure all excess food, faeces etc. is removed from Sump through the pool hose.
· Close Sump Drain Valve, replace cap.
· Begin to fill Sump with Rainwater Tank Water- will take approx 15-20 mins.
· Open all Tank Shut-Off Valves. This will return excess tank water to Sump.
· Open Sump to Pump Valve
· Turn handle on Filter to Backwash. When sump has at least 6 metal cage divisions start pump.
· Watch filter bulb to determine when backwashed water turns clear. Approx 1 minute?
· Turn Off pump
· Turn handle on Filter to Rinse. Run for approx. 10 seconds. Turn pump off.
· Turn handle to Filter. Turn pump on. You will need to turn pump off if sump runs dry. Continue filling Sump with Rainwater.
· Water level in Sump should balance out to 4 metal cage divisions.
· Do not leave until balance is achieved and sustained.
