| Tiivistelmä: | This paper presents a bioeconomic analysis of the optimal long-term management of a genetic resource in the presence of selective harvesting. It is assumed that individuals who possess a particular gene have a lower natural mortality rate and are more valuable to capture. Highly selective harvesting may cause such a gene to lose its fitness advantage. Hence, it may change the evolutionary path of the species. The results indicate that the decision to preserve the valuable gene depends on the natural rate of selection against less valuable individuals and the interest rate in a zero-cost harvesting regime. The decision to let the less valuable gene become a significatn fraction of the genes depends only on biological parameters. |
