Abstract: Excessive predation pressure from the waterfowl Phalacrocorax carbo (Great Cormorant) on Plecoglossus altivelis (Ayu) has recently been a severe problem of river environment in Japan. Local fishery cooperatives are currently suffering from economic difficulties due to decrease of the fish catch of P. altivelis. Local fishery cooperatives and municipalities have been enthusiastically trying to develop countermeasures that can effectively reduce the predation pressure; however, their effectiveness and efficiency… Show more

“…The system for the corresponding incomplete‐information case is presented in the next subsection. The habitat is assumed to be closed, which is justified if we consider the population dynamics in an inland waterbody, such as a lake and a river reach bounded by physical barriers . The period of the problem is set as (0, T ) with a fixed terminal time T > 0.…”

“…Therefore, we identify the parameter values λ HL = 0.1 (1/day) and λ LH = 0.1 (1/day), which are consistent with the reality. The model parameters appearing in Equation are specified as R = 0.01 (1/day) and c max = 0.03 (1/day) based on the previous study . The model parameters for the performance index are specified as α = 1.0, q = 0.003 (1/day), and ω = 0.2.…”
