What could be the cause? What would you have expected to see before the death? What should we look for in determining a reason for the death?

ARC features in DET Annual School Report for Wadalba

The ARC was recognised as a significant community and statewide education and research centre for Aquaculture...
"The Aquaculture Research Centre was created to support teaching, learning and research into a sustainable fish farming industry and the marine environment. The centre has become a fully compliant commercial setup and is a state focus for vocational education. A high level delegation from The Board of VET (BVET) visited the centre in September (2005) and reported favorably to the Minister for Education.
Students had the opportunity to grown three hundred trout and four hundred Australian Bass in 2005. The trout were grown to an edible size, harvested, smoked, vacuum sealed and given to school and community members who purchased a fish futures certificate earlier in the year. The Bass were taken on as a long term project on agistment for a local 'catch and release' operator."

Some Like It Hot!

The Yr10 class has begun Fish,Yabbie and Prawn Anatomy. While gathering data/research on reproduction of Yabbies it was decided that our Yabbies need light stimulation (leaving the light on) to trick Yabbies into thinking that the days are growing longer and an increased in temperature (we were running the Yabbie Tank 250l at approx. 22C using aquarium heaters) we have now turn up the heat to 25C.
We will continue observations to see if these changes trigger reproduction.

Ordered Trout Grower Pellets

Trout Grower Food is produced by Ridley Aqua-Feed Narangba Qld. However they only sell by the Tonne... a bit more than we need (at this stage)!
It is a 4mm pellet containing:Crude Protein 43%Crude Fat 26%Crude Fibre 1.33%
We were referred to Hay U Pit Supplies, also in Queensland 07 34200870.
An enquiry has been made with 'PIT Supplies' today.
The trick is to ensure we order just the right amount as its 'shelf life' can be less than 12 months. We need to maintaining the quality of the protein, and minimise the potential of the fat to become rancid/decay.
* We will advise total cost of feed including transport soon!
