How do environmental factors affect the stock–recruitment relationship? The case of the Pacific sardine (Sardinops sagax) of the northeastern Pacific Ocean

Galindo-Cortes et al. (2010) explored the effect of environmental variables on the Pacific sardine stock-recruitment relationship by incorporating these variables into the S-R function as additive random errors.

“Galindo-Cortes et al. (2010) explored the effect of environmental variables on the Pacific sardine (Sardinops sagax) stock–recruitment (S–R) relationship by incorporating these variables into the S–R function as the additive random errors.”

Both the additive-error and survey-index methods of including environmental covariates generated relatively high-quality estimates.

“Both methods generated relatively high-quality estimates, either by including environmental covariates as an additional component of the S–R function or by fitting covariates in the model as a survey index of recruits outside the S–R function.”
