Prey animals are often faced with a Hobson's choice: risk starvation or risk predation. Individuals capable of optimizing this trade-off through the use of context specific predator avoidance behaviour should be at a selective advantage. Food availability and social status have been shown to exert a strong influence on this trade-off, however, it remains unknown if these factors interact (i.e., do dominants and subordinates vary their behavioural decisions based on food availability). The purpose of this study was to examine the effects of food availability and social status, as well as their interaction, on the individual behaviour by young-of-the-year rainbow trout (Oncorhynchus mykiss) in response to perceived predation threats. Pairs of dominants and subordinates were assigned to either low, intermediate or high food availability treatments and exposed to either conspecific alarm cue (predation threat) or distilled water (no threat). The results suggest that an individual's response to a perceived predation threat is indeed dependent upon both social status and food availability.

Over the past few years, it has become more and more obvious that fish farming will become increasingly important in the future. As fish farming moves into its industrial phase, technology will be an important factor in determining its successful development. It is therefore important for scientists & representatives from the aquaculture industry to meet to define state of the art and explore future development of fish farming technology for different fish species. 81 papers and abstracts were presented at the conference. The proceedings reflect the different sections of the conference: the plenum sessions and three parallel sessions: Juvenile marine fish, open production plants, closed production plants and poster sessions.

Population dynamics and animal behaviour are two subjects which have developed almost independently, despite widespread acceptance of their interrelationship. This study aims to provide a framework for combining both fields of research. It also considers a range of conservation issues.
