Abstract
Annual lobster landings (1912-74) at the Magdalen Islands [Canada] can be represented with the Box and Jenkins method, by a 1st order autoregressive model which explains 41.9% of the total variance. Analysis of fishing effort and surface temperature yields, through a regression on principal components, a linear model that includes the first and makes use of the Dec. temperature 8 1/2 yr ago and that of the winter 3 1/2 yr ago. This prediction model explains 84.4% of the total variance. The biological interpretation is as follows: annual landings depend on available stock, on the influence of temperature on the survival probability of larvae and possibly, on a similar influence on the probability of access to sexual maturity of the 5 yr old class.This publication has 1 reference indexed in Scilit:
