摘　　要：在盐度24—27‰的海水中,用大小不同的网箱对不同规格欧洲鳗进行了不同养殖密度的生长比较。结果表明,欧洲鳗在海区网箱养殖条件下可以正常摄食生长,60天饲养期最高产量达61.8kg/m^2,增重量达34.5kg/m^2,省重率为 126.6％。在一定范围内密度、网箱大小对其生长速度无明显影响,大体上体小的鳗种,生长速度快,但25g/尾以上鳗鱼,增重率上的差异并不明显。The growth of different-sized European eels cultured in various cages were compared in different stocking density at salinity 24-27. Rusults showed: European eels could grow and ingest normally in cage, the highest production was 61.8kg/m , weight gain was 34.5kg/m2 and weight gain rate was 126.6% in 60 feeding days. Density and cage size had not significant effect on eels's growth speed in a cartain range. In general the smaller eels grew fast but there was no difference of eels which body weight was over 25g.
