碩士 / 國立中山大學 / 經濟學研究所 / 95 / The impacts that environmental factors brought to the population of the Formosan landlocked salmon are discussed in this paper and the evidence results indicate that the air temperature and typhoon have taken negative effect during past 15 years. Under the population simulations, without considering the environmental factors, it is clear that the population growth rate tends towards a steady state in the long run. On the contrary, the population would be in decline or suffer the extermination while we consider those factors.
