We use age- and size-structured population models to understand how fished populations respond to protection inside marine protected areas (MPAs). One generally expects population sizes to increase once fishing stops, but time lags due to demographics and year-to-year variation in larval recruitment can delay those increases. We present several examples of how population models can set expectations for detectable increases in fished populations will be detectable (and when they may never be detectable).
