作者用硫酸钴、硫酸铜、硫酸锌和氯化锰等盐类对鱼卵作了试验研究,浓渡为0.05～5毫克/升。实验时水中单因子微量元素含量如下:铜0.0014～0.01毫克/升,锰0.0098～0.015毫克/升,锌0.003～0.017毫克/升,钴含量比较低,仅为0.00025毫克/升。把鱼卵放入12公升孵化器中进行人工孵化。在人工孵化器中设有可以控制任何浓度的水溶液装置(见附图)。母液在混合器中由孵化车间的总管道流出的水所稀释。知道了孵化器中水的流量,就可算出预定浓度的母液需要量,并用开关调节。在这种孵化器中,进行用微量元素对不同
The authors used cobalt sulfate, copper sulfate, zinc sulfate and manganese chloride and other salts on the eggs were tested, the concentration is 0.05 to 5 mg / liter. The single-factor trace elements in water were as follows: copper 0.0014-0.01 mg / l, manganese 0.0098-0.015 mg / l, zinc 0.003-0.017 mg / l, and cobalt at a relatively low level of 0.00025 mg / l. Put the fish eggs in a 12-liter incubator for artificial hatching. In the incubator there is an aqueous solution device that can control any concentration (see attached). The mother liquor is diluted in the mixer by the water flowing out of the main pipe of the hatchery. Know the flow of water in the incubator, you can calculate the required concentration of the mother liquor, and use the switch to adjust. In this incubator, the use of trace elements is different
