The key research findings described in this project addressed the two highest research priorities identified by the Australian Abalone Grower' Association (AAGA) in 2009, prior to the commencement of this project.:

1. Improve our understanding of the effects of seasonal water temperatures on the growth of abalone; and
2. Improve our understanding of the effects of dietary protein on the growth of abalone

Members of the AAGA were interested in determining if multi-diet feeding strategies designed specifically to provide the optimum dietary protein level to the abalone in response to animal age and seasonal fluctuations in water temperature improve production. Additionally, the planned overall outcome from tis project was to develop commercial diet formulation and feeding strategies that deliver a >10% improvement  in productivity across an entire grow-out period for greenlip (Haliotis laevigata) and hybrid abalone (H. laevigata x H. rubra). To achieve this outcome, a series of laboratory-based experiments were designed to improve our understanding of the optimum dietary protein levels for greenlip abalone and also characterise the growth and feed utilisation of greelip abalone of different age classes at a range of seasonal temperatures (14-22oC) representative of those experienced by abalone in land-based facilities in southern Australia (Chapters 2 and 3). This information was then used to design and run three commercial on-farms trials at the Great Southern Waters, Costal Seafarms and Kangaroo Island Abalone (Chapters 4 and 5). The on-farm trials comprised a series of three long-term (>18 months) studies, using commercial culture practices, to evaluate the growth, feed utilisation and survival of greenlip and hybrid abalone using two different feeding strategies:

1. Single-diet feeding strategy: the current production method of feeding one standard protein for the entire trial
2. Multi-diet feeding strategy: fed a sequential combination of "high protein"/"low protein" grow-out diets for the entire trial.

1. Single-diet feeding strategy: the current production method of feeding one standard protein for the entire trial
2. Multi-diet feeding strategy: fed a sequential combination of "high protein"/"low protein" grow-out diets for the entire trial.

The key research findings described in this project addressed the two highest research priorities identified by the Australian Abalone Grower' Association (AAGA) in 2009, prior to the commencement of this project.:

1. Improve our understanding of the effects of seasonal water temperatures on the growth of abalone; and
2. Improve our understanding of the effects of dietary protein on the growth of abalone

Members of the AAGA were interested in determining if multi-diet feeding strategies designed specifically to provide the optimum dietary protein level to the abalone in response to animal age and seasonal fluctuations in water temperature improve production. Additionally, the planned overall outcome from tis project was to develop commercial diet formulation and feeding strategies that deliver a >10% improvement  in productivity across an entire grow-out period for greenlip (Haliotis laevigata) and hybrid abalone (H. laevigata x H. rubra). To achieve this outcome, a series of laboratory-based experiments were designed to improve our understanding of the optimum dietary protein levels for greenlip abalone and also characterise the growth and feed utilisation of greelip abalone of different age classes at a range of seasonal temperatures (14-22oC) representative of those experienced by abalone in land-based facilities in southern Australia (Chapters 2 and 3). This information was then used to design and run three commercial on-farms trials at the Great Southern Waters, Costal Seafarms and Kangaroo Island Abalone (Chapters 4 and 5). The on-farm trials comprised a series of three long-term (>18 months) studies, using commercial culture practices, to evaluate the growth, feed utilisation and survival of greenlip and hybrid abalone using two different feeding strategies:

1. Single-diet feeding strategy: the current production method of feeding one standard protein for the entire trial
2. Multi-diet feeding strategy: fed a sequential combination of "high protein"/"low protein" grow-out diets for the entire trial.
