A Jump‐Driven Self‐Exciting Stochastic Fish Migration Model and Its Fisheries Applications
ABSTRACT We introduce a stochastic continuous‐time model via a self‐exciting process with jumps to describe a seasonal migration event of diadromous fish exemplified by Ayu Plecoglossus altivelis altivelis. The dynamics of the stored population at a point in a river, waiting for their upward migration, increases by the inflow of fish from the ...

Abstract Animal personalities are differences in behaviour among individuals of the same species that are consistent over time and contexts. The integration of animal personality into conservation actions is hampered by limited understanding of personality traits in non‐model organisms.
