Recently, however, a number of investigations, both in the marine and in the freshwater environment, have begun to address the underlying mechanisms by concentrating on interactions between free-ranging shoals. The rates of shoal encounters can influence the opportunities for individual assortment by phenotype and selection of shoal size; act as a constraint on the observed patterns of shoal structure by restricting individual choice behaviour and were found to be high in several small freshwater species (where intershoal distances were small), but lower in marine species where shoals were more dispersed. The duration of encounters may play a role in that it affects both the time available for assessment (of the encountered shoal) as well as that for exchange of individuals. Scarce published information on the outcome of shoal encounters suggests that the outcome of shoal encounters is influenced by shoal composition but not by shoal size. Individual behaviour may have evolved to maintain shoal size when shoals encounter, but when fish populations are depleted by fishing, this trait can exacerbate range and stock collapse. Furthermore, an understanding of the dynamics of shoal encounters has important consequences for the evolution of reciprocal altruism and the transmission of information through social learning within populations. Finally, information on encounter rates between shoals and the number of individuals that are exchanged on such occasions could be important for making predictions about the spread of disease through fish populations.</dcterms:abstract> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:issued>2003-06</dcterms:issued> <dc:language>eng</dc:language> <dc:creator>Croft, Darren P.</dc:creator> <dc:date rdf:datatype="">2017-08-24T08:42:25Z</dc:date> <dcterms:isPartOf rdf:resource=""/> <bibo:uri rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <dc:contributor>Krause, Jens</dc:contributor> <dc:contributor>Croft, Darren P.</dc:contributor> <dc:contributor>Pitcher, Tony J</dc:contributor> </rdf:Description> </rdf:RDF>
