A simulation model to explore the relative value of stock enhancement versus harvest regulations for fishery sustainability

Stock enhancement Fisheries sustainability Harvest This study compares the use of commonly used tools for maintaining sustainability in fisheries: harvest restriction and stock enhancement. It seeks to steer policy decisions regarding sustainable fisheries with the comparison. A population model was built to explore the tradeoffs between the two tools. The model was applied in a case study of a Murray cod Maccullochella peelii peelii population in Australia. The study indicates that stock enhancement is less effective than measures that reduce fishing mortality.
