Age structured stochastic recruitment model for assessment of power plant impact. [Simulation of striped bass population dynamics]
The dynamics of the Hudson river striped bass (Morone saxatilis) stock were analyzed using a stochastic age structured model. The effect of river flow on recruitment was combined with the mortality due to fishing and power plant water uptake to obtain an overall effect of these variables on the fishery. Model equations and parameters were documented and their underlying assumptions presented. Preliminary model runs resulted in yields well below those actually observed. Calibration of model parameters brought these values closer to the observed yields, but stock values proved inexact. The influence of power plant mortality on fishery yield was evident, but the simulation results remain inconclusive. 11 references, 4 figures, 6 tables.
