Swimming physiology of fish and using exercise to farm fit fish in aquaculture
Speaker: Dr. Arjan P. Palstra,Wageningen University & Research Animal Breeding and Genomics, The Netherlands
Summary: The basic physiological condition of many fish species of commercial interest is constant movement. Current aquaculture conditions often represent suboptimal environments to allow such behaviour. The
stimulation of swimming exercise in aquaculture can therefore offer physiological benefits that are
worth the extra costs for inducing a flow and adjusting the systems, and may even represent solutions
for well-known aquaculture bottlenecks. Optimal exercise protocols should be developed and end
discussions about contrasting results which are obtained at different swimming speeds and other
variables that interfere with swimming physiology. I will present the most recent information coming
from our experimental trials which provides input for a discussion on the opportunities to use exercise
to farm fit fish under current and future aquaculture conditions.

Does behaviour matter in life?
Speaker: Andrea Campos-Candela
Summary: Shyness, boldness, aggressiveness, activity, sociability… all these personality axes define animals at the individual level, and individual specificities along them tend to be correlated. Recently, these patterns of covariation have been enlarged to accommodate movement behaviour within a personality-dependent spatial ecology theory. Most animals tend to forage, reproduce and develop any activity within specific bounded space, which leads to the formation of home range areas. Animals differ from each other individually in their home range and movement behaviour leading to well-contrasted spatial behavioural types.
However, many open questions remain in the field of ecology: How does spatial behavioural types connect with life history? What is the role of personality in ecology?
In my PhD thesis, I aimed to address from conceptual, empirical and theoretical perspectives such a cornerstone questions in behavioural ecology. I propose a unifying behavioural-bioenergetics theory to test the adaptive value of behaviour based on dynamic energy budgets. This behavioural-bioenergetics model connects i) personality traits, ii) home range, iii) physiology and iv) LH traits through an interwoven of mass/energy fluxes. I explore empirically how personality relates with feeding behaviour. Moving forward to including management scenarios, I provide two examples on how the consideration of home range related theoretical concepts might improve the management of wild populations.
