Research on the biology of Triplophysa strauchiiin Turks River
摘要
Abstract
[Objective]To study the systematic biology characteristics of Triplophysa strauchii in Turks River,lay a foundation for the development and utilization of its germplasm resources,and consolidate the bas-ic biological data of fish endemic to Xinjiang.[Methods]From 2022 to 2023,488 samples of T.strauchii were collected in the Turks River,and their morphological characteristics were identified by classical biological methods,and their biological characteristics such as age and growth were analyzed.[Results]T.strauchii had elongated body,slightly flattened head,slightly raised head,blunt snout,wider lower mouth,curved back outline,thick round forebody,fusiform,width of caudal stalk starting point was obviously larger than caudal stalk height,smooth skin,no scale,and complete lateral line..The mean age of T.strauchii was(1.74±0.77)+,the maximum age was 4+,the minimum age 0+.Among them,the dominant age was 2+,accounting for 46.80%.The correlation equation between standard length and body weight was as follows:W=1.15×10-5L2.968(R2=0.92);The growth equations was:Lt=161.13(1-e-0.32(t+0.20))and Wt=40.82(1-e-0.32(t+0.20))2.968,asymptotic standard length was:L∞=161.13 mm,asymptotic body weight W∞=40.82 g,t0=-0.20,k=0.32,ti=3.23;The fullness coefficient was:k=1.21.[Conclusion]Triplophysa strauchii,a cold water fish with a body shape of spindle,is a carnivorous fish feed organism with uniform growth rate,small age composition,strong adaptability,stable growth characteristics,large number and extremely palatability in the Turks River,which has great development and utilization value and ecological significance.As the dominant indigenous fish in the Turks River.关键词
