Abstract In July 2012 and May 2013, 70 Chinese spined loach Cobitis sinensis were caught in traps and electrical fishing in Donghe River of Wangcang County, Guangyuan City, Sichuan Province and fixed in 10% formalin solution and then stored in 5% formalin solution, and another 43 samples were transported to the laboratory with plastic bag oxygenation. After routine biological measurements, the viscera of the tested fish were taken out, and the intestinal length, eviscerated weight and gonad weight were measured to investigate the growth and reproductive biology of the fish including food item analysis, male and female identification and sperm longevity. The Chinese spined loach had body length (L) of 34.92—102.85 mm, body weight (m) of 0.34—9.84 g, and eviscerated weight of 0.31—8.09 g, and was divide into 5 age classes, determined by vertebra, with dominant 2—4 age classes. The Chinese spined loach had good growth before 3 year old, low growth afterwards, with function between body length and body weight of m₁=0.00001215L^2.896, r²=0.939, nearly isometric growth. The relative condition factor was generally found to be less than 1, without significant difference in Fulton condition factor between female and male (P>0.05), even though smaller in males than in females. For the over 1 year old loach, however, there was slightly larger Clark condition factor in males than that in females. The Chinese spined loach had sexual ratio (♀∶♂) of 1∶1.69, and maturity at two years old age. The sperm survived for 14 seconds in distilled water, and longevity of the sperm was shown to be increased first and then decreases with the increase in NaCl concentration, with the maximal longevity (184 s) at NaCl concentration of 0.25%. The Chinese spined loach had absolute fecundity of 427—4047 eggs per female, with mean value of 1949.82 eggs, and relative fecundity of 107.56—566.09 eggs/g, with mean value of 356.07 eggs/g. The peak period of spawning was observed from mid-June to mid-August, spawning in batches, and roughly the same fecundity each batch, and the zygote is demersal and slightly viscous.
