Embodiment 1
[0022] The method for ecologically breeding the pufferfish seedlings in a breeding pond of the dark-patterned puffer of the present invention comprises the steps of pond preparation, stocking of the puffer parents, inoculation of cladocerans and copepods, stocking of the black-patterned puffer, feeding of bait, and brooding of eggs. The production steps of shrimp stocking, daily management, pulling nets and catching, including:
[0023] 1) Pond preparation: choose an earthen pond with a flat bottom. The pond is preferably 2m deep, 1.5m water level, and 2.5-5.0 mu in area; each pond is equipped with 1-2 1.5kw aerators, and the water inlet is covered with double layers Filter the pond with 60-mesh sieve mesh bag, and use 300-400 catties / mu of quicklime to spray and disinfect the pond. After the pond has been disinfected for 2 days, it will be soaked in water until the bottom of the pond is submerged. After soaking for 48 hours, it will be completely drained and exposed to the sun ...
Embodiment 2
[0033] Using the above method of the present invention, in 2016, at the 58th Research Base of Fengxian Research Base of Shanghai Fisheries Research Institute # The pond covers an area of 4 mu. On April 12, 350 local wild puffer fish were stocked; on April 29, 2,100 puffer fish were raised; on November 15, 1,810 puffer parents were obtained, which survived The rate was 86.2%. There were 325 scorpionfish parents, with an average size of 56.3g in weight and 25.0cm in length. The survival rate was 91.14%, and the unit yield was 9.15 jin / mu. On the second day, the net was pulled, and a total of 2,000 scutellaria seedlings were obtained. The average size of the tail is 6.8g in weight and 12.6cm in length, and the unit output is 500 tails / mu.
Embodiment 3
[0035] Using the above method of the present invention, in 2018, in 2 middle schools of Fengxian Scientific Research Base of Shanghai Fisheries Research Institute # The pond covers an area of 2.5 mu. On April 19, there were 2,500 first-year fish fingerlings of the dark-patterned oriental puffer, the stocking density was 1,000 fish / mu, and the size was 136.6g / tail; 500 first-year fish were stocked; November 7 The net was drawn to obtain 2,130 commercial fish with dark stripes, 362.3g / tail, with a survival rate of 85.2%, and 290 saury parents, with an average size of 33.93g in weight and 21.09cm in length, with a survival rate of 58.00% and unit output. 7.87 catties / mu; accumulatively obtained 1,878 scallops, with an average size of 11.18g in weight, 14.60cm in length, and a unit output of 751 / mu.
