. Studies were conducted on the growth performance and development of one‐year‐old fingerlings of seven species in lake pen culture. It was found that the body weight and length of the fingerlings increased evenly with each passing month. Based on the increase of length, these 7 species could be categorized into two groups; while based on body weight gain, they could be categorized into three groups. The growth Index of power functional relations concerning the weight and length ranged between 2·8 and 4·0, indicating that the two growths were in parallelism. It was considered that the condition factors should be calculated with b ‐value according to the differences of fish species and ages (month). The monthly average indexes of the length and weight increases of the seven species were calculated.
