Study on Viral Nervous Necrosis (VNN) Disease as Climate Changes Effects Model in Mugilidae fish (Liza klunzingeri & Mugil cephalous) of Persian Gulf and Oman Sea (original) (raw)

Abstract

The Climate changes could be basic phenomena in different ecosystems. Some environmental and ecological changes such as red tide and temperature increment could be considered in causing Emerging Disease. Climate warming will be accompanied by increase of average global temperatures. The rate of Global warming will be rise to 1.1°C to 6.4°C so it had been cleared that by climate warming the disease will increase. By 6-fold increase in the temperature, the rate of fish mortality will be rise to 82 to 100 times (4 th IPCC assessment report, 2007). Red tide or planktonic blooming is a phenomenon that phytoplankton accumulate rapidly in the water surface. Some kinds of red tide will be resulting to produce natural toxins, reduce dissolved oxygen and could be greatest risk of red tide that causes mortality in wild aquatic marine and coastal fishes. In Persian Gulf Planktonic blooming started in early October, 2008 from Hormuz and it was observed at the southern coast of Qeshm, Bandar Abba...
