Skeletal malformations in Australian marine finfish hatcheries
The Australian finfish aquaculture industry has a target to more than treble production from 2005 to100,000 t p.a. by 2015. Most of the current production is from sea cage culture of Salmo salar and Thunnusmaccoyii but new and emerging species are predicted to have a faster increase in production an...

The Australian finfish aquaculture industry has a target to more than treble production from 2005 to100,000 t p.a. by 2015. Most of the current production is from sea cage culture of Salmo salar and Thunnusmaccoyii but new and emerging species are predicted to have a faster increase in production and were thefocus of this study. The quantity and quality of hatchery-produced fingerlings is an impediment to achievinggrowth in the marine finfish sector. A survey of 18 hatcheries revealed that 44% indicated skeletalmalformations were a significant issue in hatchery production, and 89% reported variability in malformationrates between production batches. Samples of fish from selected hatcheries were cleared and stained forassessment of abnormal bone development.
