Class Activities 28/7/05
Yr9 were joined in the ARC by Stage 3 students (yrs 5-6) today to grade Trout and feed fish.
Trout had previously been graded to ensure that each Trout had feeding access to grow at the maximum rate. 3 tanks had been set aside to enable large, medium and small gradings. Today Trout that had been graded as medium (T4) and living in a polyculture with 2 very large Silver Perch were graded to T1 (Large) and T3 (Medium).
All students enjoyed the interaction and learned a lot from each other. Jack (Yr6) took some photos see above.

Wyong Councillors Visit ARC
An enthusiastic ‘caravan’ of councillors from Wyong Shire visited the ARC today to get first hand experience of the exciting learning and research venture which is known as the ARC. Councillors were impressed with the underpinning environmental philosophy that the ARC has been built on:
A complete recirculation, commercial standard Aquaculture learning and research centre that uses only rainwater and advanced filtering techniques to ensure NO wastage of water occurs
Research and development of sustainable food production
Effective and efficient use of a small, intensive allocation of land to achieve maximum growth of both native and introduced species
OH&S teaching and learning
Industry partnerships with: Central Coast Aquaculture Foundation, Swimart, WaterCo, Wyong Shire Council, CIBA and MPG Fish Kariong.

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.
