SAD News 81 Australian Bass Dead!

We had pump failures (2) in the ARC Thursday March 16 which resulted in loss of air and recirculated water. 81 Australian Bass died, all from Tank 3. Tank 3's population was at a level that resulted in total loss of oxygen, so death. Tank 4 had less population and was able to survive. The air compressor is being evaluated. Recirculation has been restarted. SAD!

The Rain in ... falls mainly on Norah Head?

Tadpoles and Frogs Sourced

A collection of Tadpoles and Frogs have been obtained from a single source to create herpetoculture. This is a significant research task for our students (management team) leading to the award of 'school certificate'. The amphibians will be released into their new home Tuesday. Why are strict regulation made when collecting Tadpoles and Frogs? ** Photos by Emily

February 2007 Update

Australian Bass were transfered from the office foyer area of the school to the ARC. One dead Bass was removed from the aquarium. This will enable a 'yearly' clean of the office aquarium and restocking with Barramundi

Chrysanthemums are thriving due to recent rain and continued watering from our recirculation system. Thanks to our MAT classes for the weeding and care. We expect that these plants will set flower heads in April, ready for sale prior to mother's day. Sale of 'bunchjes' of Chrysanthemums assists the ARC investments in farming and research.
