Disease Problems in Artificial Propagation of Salmonids

Evolutionary effects of alternative artificial propagation programs: implications for viability of endangered anadromous salmonids

Most hatchery programs for anadromous salmonids have been initiated to increase the numbers of fish for harvest, to mitigate for habitat losses, or to increase abundance in populations at low abundance. However, the manner in which these programs are implemented can have significant impacts on the evolutionary trajectory and long-term viability of populations. In this paper, we review the poten...

مطالعه اکولوژیک از سرچشمه رودخانه قره سو(سراب روانسر) در استان کرمانشاه واقع در غرب ایران در پائیز 1378 انجام شد، حداکثر دمای آب 20 درجه سانتی گراد بود، هنگام مطالعه دما در سرچشمه 18 سانتی گراد بود، مقدار عناصر شیمیایی آب اندازه گیری نشد. در این پژوهش لاشبرگ های درختی از بید، چنار، اقاقیا جمع آوری سپس توسط بخش هرباریوم دانشکده کشاورزی دانشگاه شناسایی شدند. وزن خاکستر خشک afdm در(نمونه برداری ...

Artificial Life Model of Dengue Host-Vector Disease Propagation

The paper presents an agent based model of the Aedes aegypti mosquito, which considers mosquito population dynamics and a speci c population control strategy, as well the dengue propagation in mosquito (vector) and human (host) populations. More speci cally, this study concerns the impact that the RIDL strategy (Release of Insects carrying a Dominant Lethal gene) has on the infection period amo...
