By measuring the growth rings of the scales，the age and growth of 358 specimens of Acrossocheilus parallens which were collected from July 2007 to June 2009 in the Beijiang River were studied. The annuli on scales were clear，the pattern of sparseness-denseness was visible in the prezone region while the cut pattern was present on the rear-side region. The annuli on scales was formed once a year, the annuli formation took place primarily between February and March each year. Ages ranged from1+ to5+ years for females, mainly in1+ to 3+ years; and 1+ to 4+ for males, mainly in 1+ to 2+ years for males. The standard length of female ranged from 5.7 to 14.4 cm, with the majority were from 7.0 to 13.0 cm; while the male ranged from 5.7 to 12.6 cm, with the majority were from 7.0 to 11.0 cm. The body weight of female ranged from 4.75 to 108.40 g, but most fish ranged from 10.00 to 30.00g; while the male ranged from 4.02 to 74.92 g, with the majority were from 10.00 to 20.00 g. The relationship between standard length (cm) and body weight (g) was W♀ = 0.017L3.198; and W♂= 0.023L3.025, and W = 0.017L3.167 for the combined sexes. Females and males exhibited statistically significant differences in growth. The relationship between standard length and scale radius (R) was L♀ = 3.126R + 1.869 and L♂ = 2.875R + 2.152. The von Bertalanffy growth arameters based on length-at-age data were L∞ = 17.143 5 cm, k = 0.270 5/a, W∞ = 150.347 4 g，t0 =﹣0.614 6 year for females, and L∞ = 17.236 5 cm，k = 0.226 9/a，W∞ = 126.468 6 g，t0 =﹣0.921 5 year for males. The growth inflexion point were 3.68 years and 3.96 years for females and males, when Li = 11.8 cm, Wi = 45.26 g for females, and Li = 11.5 cm, Wi = 37.60 g for males. To protect the population of A. parallens in Beijiang River, we suggest only fish longer than 10.0 cm (age 3) should be harvested.
