Inconstant catchability among individual fish has been widely recognized ... as a major source of error in depletion estimates of population size when using models [that] assume constant catchability. Inconstant catchability is a feature of populations that contain individuals with different vulnerabilities to capture or when their behaviour changes with successive hauls. The effect is to cause a rapid depletion of the more vulnerable individuals after the first unit (or few units) of effort is applied, leaving behind a pool of animals with a lower [catchability].  2, fiche 1, Anglais, - inconstant%20catchability
