兴国岁水建立兴国红鲤种质资源保护区的可行性探讨

岁水是兴国县境内的两大河流之一,河长56.1 km,流域面积77.7 km2,占全县径流量的23.6%。据调查,岁水保护区具有以下优势：（1）水质好,溶解氧为6.48 mg/L-7.72 mg/L,透明度为20 cm-30 cm,pH值为6.4-7.2;（2）水生生物丰富;（3）鱼类种类繁多,共5目10科30种;（4）兴国红鲤资源丰富,为优势种;（5）兴国县已建立了国家级兴国红鲤良种场,该县已具备保护兴国红鲤种质资源的设备与技术。因此,认为有必要在兴国县建立兴国红鲤种质资源保护区,而岁水是理想的场所。

Feasibility Discussion on Building Genetic Resource Conservation of C.c.varsingguonensis in Suishui Nature Reserve of Xingguo

Suishui is one of the two main river in Xingguo country overall length are 56.1 km and the area of basin are 77.7 km^2. It is 23.6% of the Xingguo total runoff. Based on the study,the following advantages were found in suisbui nature reserve： （ 1 ） good water quality, dissolved oxygen 6.48 mg/L · 7.72 mg/L, transparency ：20 cm -30 cm, pH is 6.4 - 7.2 ; （2） abundant hydro - organisms ; （3） rich fish species, 5order, 10 families and 30 species; （4）plentiful resources of C. c. varsingguonensis, they are dominant species; （ 5 ） there have Created country-level of C. c. varsingguonenzis seed multiplication farm in Xingguo country, this country have device and technique to protect it. Therefore,it is necessary to building the genetic resource conservation for C. c. varsingguonensis and Suishui nature reserve of Xingguo is the ideal location.
