Abstract：The effect of morphometric traits on body weight and net weight of Misgurnus anguillicauda-tus was studied using correlation analysis,path analysis and regression analysis.In total,120 M.an-guillicaudatus were randomly sampled.Body weight (BW),net weight (NW),total length (X1),body length (X2),snout-vent length (X3),postanus length (X4),periproct (X5),anal body height(X6),anal body breadth(X7),head length (X8),head height (X9),head breadth(X10),interorbitalspace (X11),nasal space (X12),trunk length (X13),body depth (X14),body breadth (X15),caudalpeduncle length (X16),caudal peduncle height (X17),dorsal fin girth (X18),body height on dorsal fin(X19),snout length (X20),and predorsal length (X21) were measured for all individuals.The resultsshowed that:(1) all correlation coefficients between phenotyoic traits and body weight and,net weightwere at highly significant (P＜0.01);and (2) the correlation indexes of the selected morphometrictraits to body weight and net weight were 0.947 and 0.948,respectively;the utmost direct actions oftotal length (X1) to body weight and net weight were 0.341 and 0.348,respectively;the utmost indi-rect actions of snout-vent length (X3) to body weight and net weight were 0.636 and 0.637,respective-ly.In addition,multiple regression equations used to estimate body weight,and net weight of adult M.anguillicaudatus were established.
