Quantifying Temperature Effects on Fall Chinook Salmon.

摘要

The thermal regime of rivers has been altered by human activities (Caissie 2006). Understanding the influences of these changes on aquatic biota is important so that appropriate management strategies can be devised. This report reviews literature pertaining to relationships between water temperature and fall Chinook salmon. Empirical models, developed from multiple sources of data, are also presented. Some of these may be incorporated into salmon population models such as the San Joaquin Fall Chinook Salmon model that is currently in development. The report is organized into three sections. The first section deals with the effects of temperature on the distribution of redds and the subsequent timing and development of freshwater life stages. The second section deals with temperature effects on survival of eggs and alevins. The third section treats temperature effects on juvenile survival.
