摘 要: 目的研究盐度和pH突变对裸项栉鰕虎鱼仔鱼存活率的影响。方法实验选取了五个不同日龄(2d、4d.6d、8d和10d)的仔鱼,设置了7个不同盐度突变水平(O、10、20、30、40、50和60)和6个pH突变水平(5、6、7、8、9和10)。结果96h的实验结果表明,日龄、盐度和pH均对裸项栉鰕虎鱼仔鱼的存活率产生影响,随日龄的增大,各处理组仔鱼存活率升高;0和60的盐度以及pH为10的各组裸项栉鰕虎鱼仔鱼死亡。结论裸项栉鰕虎鱼仔鱼对于一定范围内盐度(10—50)和pH(5—9)的突变具有很好的适应性。 Objective To study effects of salinity and pH change on the survival rate of the Bareneck goby larva. Methods Five daily ages (2 d,4 d,6 d,8 d and 10 d),seven salinities (0,10,20,30,40,50 and 60) and six pH (5,6,7,8,9 and 10) were designed. The data was eollected during 96 hours experiment. Results The effects of the daily age, salinity and pH on survival rate of the Bareneek Goby larva were significant. The survival rate of the larva increased with daily age. On the condition of salinity 0 and 60 and of pH 10, Goby larvas were dead. Conclusion The larva could adapt the changes of salinity (10,20,30,40 and 50) and of pH (5,6,7,8 and 9) thoroughly.
