A method for inferring movement rates of fish from mark–recapture data
Abstract: This paper presents methods to infer the rate of movement of fish that are marked ... , released, and subsequently captured. The information that is available is the location and date of the ... release and the recapture. In addition, the intensity of fishing effort (i.e. sampling) by location and ... time is known. The simplest approach is to make a frequency plot of the distance between each release ...
