Yard Maintenance

Lawns mowed- looks great! Thanks Dave
Fence panel 'kicked in'???

Clean and Maintenance 29/9/05

Constructed rope protection to draw net towards centre of tank to prevent Trout from escaping.
Backwashed, corrected water flow.
AutoFeeder working well. All fish fed well. Worms to Australian Bass, Murray Cod

AutoFeed Activated

Mr Godwin has completed the digital timing to enable the trout to be fed over a 24 hr period. :-)Photos to come...

*
1 Trout Jumped- Dead :-(
1 Silver Perch A7- Dead :-(

Clean and Feed

T3 & T4 have been isolated from the recirculation system; brushed clean, riser removed and recirculation stopped awaiting arrival of new fish. Tanks have found a balance in height aligned with the height of gravity drain pipes to sump.
The LAB has been cleaned and all fish fed well. Australian Bass and Murray Cod are feeding well on garden worms from our Worm Farm/s.

*Added 250g of Salt to Sump to restore salinity/conductivity.
2 Fish Dead A3 :-(. Fish were added from home aquarium on 23/9/05

Ordered & RFQ for Equipment

Ordered Tagging Gun, Replacement Needle and Tags + Probiotic Bacteria Sources for BioFilter/s from Aquasonic.
http://www.aquasonic.com.au/

Probiotic Bacteria Disease Prevention Treatment. Chemical Free. Copper Free. Drug Free.
Helps Control White Spot, Aeromonas spp., Vibrio spp., Velvet and Fungus infections.
ProBio-Plus is a new concept in disease prevention, containing natural probiotic bacteria,
which help beneficial microbes control water quality. Probiotic bacteria are sometimes called
"protector" bacteria. Probiotic bacteria create a hostile environment for harmful pathogenic
bacteria, which cause disease. They do this by competing for the same food sources.

Requested quotes for:

• Ultraviolet Water Purification
• Foam Fractionator

Will advise decision soon.

Born FREE! Tagging our Silver Perch

Our Silver Perch is returning back to MPG Fish (Kariong) for the Central Coast Community Chest- Fishathon. 'Perchy' will be the top prize for the weekend! We were going to call him 'Parrot' because he hangs around perches??? No animals were harmed in this tagging exercise.

The data will assist us in developing a Management Plan for the Mount Panang Gardens and information on movement patterns, growth rates, and seasonal variations. As scientists or anglers, we need answers. Without them, we will never manage our fisheries successfully.

*** Photos to be published in local paper. We will scan and add to the Blog.

• Use a water soaked cloth/cloth glove when handling the fish so it won't remove the fish's protective slime. Don't hold the fish by the gills or eyes.
  The less you handle the fish, the better the chances of the fish surviving.
• Have tag applicator loaded and in a handy spot before you start.
• Lay the fish on the right side to tag and measure.
• Insert the tag as close to the dorsal fin as possible. Anchor the tag between the vertebrae and dorsal fin spines. The tag should be inserted so the streamer slants toward the tail of the fish. Tug lightly on the streamer to insure a snug fit.
• Record all information on our data sheets provided (length, date, time, location, etc.) Also record any observations of the fish health or the general procedure.
  To release the fish gently place in water, supporting mid section and tail until it swims away. An exhausted fish can be resuscitated by gently moving it back and forth in the water, forcing water through its gills.
• Periodically clean tagging and venting tools with alcohol or bleach.

I can see clearly now the algae has gone! Glass Clean

Used Magnetic cleaner to clean all glass Aquariums... A1, A2, A3, A4, A7
Prepared A2 ready for new fish.
Fish fed well.
A7 Silver Perch feeding GREAT! Corey is looking after this Aquarium and the fish. We think the Perch may have eaten the Yabbies?
Silver Perch transported to MPG Fish for Central Coast Community Chest. Bye Bye 'Perchy'.
Backwashed system.

Clean and Feed 17/9/05

All fish fed well. Murray Cod starting to show significant growth. Hoping to move to 'real' worms for Australian Bass soon, fed with Blood Worm, they need good quality live food to really push them on.

Wadalba Community School ARC to assist in TAGGING of fish for MPG Fish, Community Chest Fishout Day. Our Industry Partnership is significant in a WIN WIN WIN relationship.

Backwashed sump, topped with Tank water. Very small amount of rain added small increase in rainwater tank.

Maintenance & Classwork 16/9/05

Weight of Trout Pellets/Food
- a single release with Autofeed produced approx. 6.4g of pellets (we will need to obtain multiple readings and average out the weight to better determine flow).
A plastic container of Trout pellets weighs approx. 358.5g
* Measured with a Triple Beam Balance (see diagram)

Filled AutoFeeder with Trout Pellets
Filled feed containers in fridge.
Fed Australian Bass/Murray Cod Blood Worms (Midge Larvae) ...love it!
Fed Porter's Creek Yabbies A4 (will move some to A7 to help clean excess food)
Fed Silver Perch fingerlings
Work on DTP brochures continued.
