Then we use the Runge-Kutta method to analyze the optimal management of seasonal fisheries in a discrete-time setting. We analyze both the case of quarterly harvest and the case of monthly harvest, and we compare these to the case of annually harvest. We find that seasonal harvesting is a win-win optimal solution with higher harvest, higher optimal steady state equilibrium, and higher economic value. We also demonstrate that the discretization method overcomes the economic and biological weakness and preserves the strengths of both continuous and discrete-time bioeconomic modelsengtechnical reportopen accessBioeconomic modelingRunge-KuttaSeasonal fisheriesSeasonal harvestingKalman-filterNorth-East Arctic codAnálisis numéricoEcuaciones diferencialesInvestigación operativa (Matemáticas)Biología marinaEcología (Biología)Peces1206 Análisis Numérico1202.07 Ecuaciones en Diferencias1207 Investigación Operativa2401.06 Ecología animal
