Abstract：In order to investigate the growth pattern of Macrobrachium nipponense in pond culture in northern China，on June 16th， 2024，897 Macrobrachium nipponense samples were randomly sampled from aquaculture ponds，including l6o brooding shrimp（body length range of 3.8～7.5cm ，aweight range of 0.83～6.43g ），and 737 non brooding shrimp（a body length range of 3.0～9.6cm， a weight range of 0.22～10.72g .The results showed that，the correlation curve between body weight and body length was very close for both brooding shrimp and non brooding shrimp ，the average body length and weight of non brooding shrimp were higher than those of brooding shrimp;from the perspective of body length range，the average body length of Macrobrachium nipponense（whether it was a brooding shrimp or a non brooding shrimp）increased with body weight ，and when the body weight reached 7.95g ， the body length began to decrease.

Key words： Macrobrachium nip ponense ; body weight; body length; regression equation; northern region；pond aquaculture

日本沼蝦（Macrobrachiumnipponense），俗稱青蝦、河蝦，具有生長快、抗病力強(qiáng)、口味鮮美、營養(yǎng)豐富和價(jià)格穩(wěn)定等優(yōu)點(diǎn)，深受廣大消費(fèi)者的喜愛，是我國重要的淡水經(jīng)濟(jì)蝦類[1]。（剩余6062字）
