SPECIES
This project will greatly assist the Fremantle Maritime Centre to establish the light regimes required for the WA dhufish larvae and will provide greatly needed support for the larval rearing portion of the project. The information provided should enable the FMC to avoid long term trial and error light regime experimentation and increase larval survival. The information obtained will also be of benefit to Murdoch University (FRDC Project 96/103 - Determination of biological parameters required for managing the fishery for Western Austration dhufish) to assist in identifying (currently unknown) areas which may act as nursery grounds for the WA dhufish larvae.
1. To establish the timing and sequence of development of photoreceptors inthe retina of the dhufish.
2. Relate photoreceptor changes to possible lifestyle requirements during the larval period of the WA dhufish to provide advice on a suitable light environment to the Fremantle Maritime Centre's WA dhufish culture program.
