摘要 为了确定黑尾近红鲌仔稚鱼的适宜运输密度,实验选取平均体长为(27.08±3.09)mm、平均体质量为(0.11±0.04)g的黑尾近红鲌仔稚鱼作为实验对象,采用氧气袋运输,研究了不同运输密度(20、40和80 g/L)下2h、4h、6h、8h和10h后黑尾近红鲌全鱼皮质醇、乳酸、糖元含量及氧气袋内水质的变化。结果显示:运输后各组黑尾近红鲌的平均存活率均在99%以上,但不同密度之间差异显著(P<0.05);各组水体总氨氮浓度均随运输时间显著升高,而水体pH均随运输时间显著降低,且不同运输密度间差异显著(P<0.05);低密度组水体DO浓度(14.20—20.93 mg/L)在不同运输时间均显著高于高密度组(2.42—2.88 mg/L;P<0.05)。各组全鱼皮质醇含量均呈现出先升高后降低的趋势,运输4h和6h时显著高于其它运输时间(P<0.05),且不同运输密度间差异显著(P<0.05);各组全鱼乳酸含量均随着运输时间显著升高(P<0.05),但不同密度之间无显著差异(P>0.05);各组全鱼糖元含量在运输2h时显著降低(P<0.05),但此后维持在稳定水平(P>0.05)。运输密度和时间对黑尾近红鲌鱼苗的全鱼皮质醇、存活率、水体总氨氮和溶解氧的影响存在显著交互作用。 To determine the suitable transport density of Ancherythroculter nigrocauda Yih et Wu,Ancherythroculter nigrocauda with the average body mass of(0.11±0.04)g and average body length of(27.08±3.09)mm were conducted with three density(20,40 and 80 g/L)and five transport times(2,4,6,8 and 10h)to measure cortisol,lactate,glycogen content of Ancherythroculter nigrocauda and the water quality in the oxygen bag.The results showed that the average survival rate of Ancherythroculter nigrocauda in each group was above 99%after transportation,but the difference between densities was significant(P<0.05).The total ammonia nitrogen concentration of each group increased significantly with the transportation time and the pH decreased significantly with the transportation time,and the differences between different transport densities were significant(P<0.05).The concentration of DO in the low-density group of 14.20—20.93 mg/L was significantly higher than that in the high-density group of(2.42—2.88 mg/L;P<0.05).The cortisol content of each treatment group increased first and then decreased,the cortisol contents at 4h and 6h were significantly higher than other transport times,and the difference between different transport densities was significant(P<0.05).The lactate content of each group increased significantly with the increased transportation time(P<0.05),but there was no significant difference between different densities(P>0.05).The glycogen content of each group was significantly reduced after 2h of transportation(P<0.05),and then remained stable.These results indicated that there was a significant interaction between transport density and time on cortisol,survival rate,total ammonia nitrogen and dissolved oxygen of Ancherythroculter nigrocauda,and the optimal transport density of Ancherythroculter nigrocauda was 40 g/L.
