Rotating spatial harvests and fishing effort displacement: a comment on Game et al. (2009).
Game et al. (2009) explored using rapid rotational fishing for increasing herbivore biomass. Their results depend crucially on the assumption that fishing effort that was in closures disappears, rather than shifting elsewhere. If effort shifts, rapid rotation has no effects, but previous age-structured analyses show benefits of longer period rotation that are robust to effort displacement.
