张家口地区水产推广站位于桑洋盆地的涿鹿县西北部,北纬40.3°,东径115.2°,海拔700米左右。全年可照时数4400～4450小时。日可照百分率61～68％。全年日照总时数2900～2980小时。养鱼池水源为地下水。水源出水温度为14℃。由于地理环境、气候条件和水源温度等因素。决定了该站养鱼池水温的特异性。本文主要讨论温度对鱼类的影响。提出生产安排时序等对养鱼适温季节利用的意见,水平所限,谬误难免,希望批评指正。一、张家口地区养殖水域水温特性
The Zhangjiakou area aquatic product promotion station is located in the northwestern part of Zhuolu County in the Moyang basin with a latitude of 40.3 ° and an altitude of 115.2 ° at an altitude of 700 meters. The annual number of hours 4400 ~ 4450 hours. According to the percentage of 61 to 68%. The annual total hours of sunshine 2900 ~ 2980 hours. Aquarium water for groundwater. Water source temperature is 14 ℃. Due to the geographical environment, climatic conditions and water temperature and other factors. Determined the station fish pond water temperature specificity. This article focuses on the effects of temperature on fish. Put forward the timing of production arrangements and other views on the use of fish breeding temperature season, the level of limitations, fallacies are inevitable, I hope criticism and correction. First, Zhangjiakou area breeding water temperature characteristics
