Spatiotemporal variation in maturation: a case study with American plaice ( Hippoglossoides platessoides) on the Grand Bank off Newfoundland
Fisheries management usually does not explicitly account for spatial variation in life history traits within populations. However, for some stocks this spatial variation may be substantial. We develop a spatiotemporal generalized linear model and fit the model to a long time series of maturation dat...
