Abstract

In 2016 and 2017, the ecological pond breeding experiment of Charybdis japonica was carried out, with a total of experimental area up to 4 ha. Through two years of experimental research, it obtained a total of 48 950 kg of C. japonica, with an average output of 12 237.5 kg/ha. The production output value was 2.367 5 million yuan, the total production cost was 831 700 yuan, the net profit was 1.535 8 million yuan, the average profit was 384 000 yuan/ha, and the input-output ratio was 1:2.85. The average proportion of C. japonica population with a production weight of 150 g or more was 7.9%. The proportion of the group of 120-150 g was relatively large, with an average of 80% in two years, and the proportion of the group below 120 g was relatively small, with an average of 12% in two years. The cumulative harvest of shellfish in two years was 65 700 kg, with an average output of 16 425 kg/ha, the production output value of 738 100 yuan, the production cost of 295 500 yuan, the net profit of 442 600 yuan, and the average profit of 110 700 yuan/ha.
