Discussion summary: session 4
| In this session on the relevancy of fish behaviour to fish catchability,the focus was on (i) quantifying fish reactions to stimuli producedby fishing vessels and fishing gear, and their effect on theprecision of resource surveys and the success of commercialfishery operations, and (ii) applying knowledge of fish behaviourto improve estimates of survey catchability, species and sizeselectivity of commercial fishing gears, and the design of ecosystem-friendlyfishing gears. Dr Olav Rune Godø!, IMR Bergen, gave the opening lectureon "Fish behaviour and fish catchability in modern ecosystem-basedfishery management", which was followed by 13 oral presentationsand a summary presentation of the 16 posters associated withthis theme session. These 2g presentations centred around theinteraction of environmental factors – both natural andanthropogenic – with various fish sensory receptors toresolve reaction complexity in
