Embodiment 1
[0029] The method for three-dimensional cultivation of puffer puffer obscurus, vannamei, and water spinach of the present invention comprises the following steps:
[0030] 1) Pond preparation: Choose an earthen pond with a flat bottom in Jiangsu and Zhejiang. The pond is preferably rectangular with a depth of 2m, a water level of 1.5m, an area of 2.5-5.0 mu, and each pond is equipped with 1-2 1.5kw aerators. The outlet is covered with a 60-mesh sieve and filtered with a tulle bag. Thoroughly clean and disinfect the pond before use, thoroughly remove wild fish and shrimp, add water until the bottom of the pond is submerged and soak, dissolve 50-80 catties / mu of bleaching powder in water, and the supernatant Splash the pond for disinfection, turn on the aerator when splashing and within half an hour after splashing, then turn off the aerator, the pond water will stand still for 3-4 days, after the pond water is clear to the bottom, completely drain the disinfectant water, and the...
Embodiment 2
[0040] Using the above-mentioned method of the present invention, in 2019, three test ponds (numbered 2) of three-dimensional planting models of pufferfish, vannamei, and water spinach were carried out at the Fengxian scientific research base of Shanghai Fisheries Research Institute. # East, 2 # West, 4 # Middle) and three control ponds (numbered 4 # East, 4 # West, 2 # Middle) conducted a comparative breeding experiment, and set up three parallel groups, each with an area of 2.5 mu. On April 25, puffer pufferfish obscurus (average size: 154.61g / tail) were stocked, and 2,000 fish were stocked in the three-dimensional planting test pond / pond, the stocking density is 800 / mu, and the single culture control pond is stocked with 2500 tails / pond, and the stocking density is 1000 tails / mu; on May 21, in the three-dimensional planting test pond, each pond stocked 2.9 shrimp seedlings of Penaeus vannamei. Ten thousand tails, stocking size of shrimp seedlings is 0.8-1.0cm, the s...
Embodiment 3
[0044] Using the above method, in 2019, the three-dimensional breeding model of puffer puffer, Penaeus vannamei and spinach was carried out at the Qingpu scientific research base of Shanghai Fisheries Research Institute, and a comparative breeding experiment was carried out with the three models of puffer puffer and Penaeus vannamei alone. And set up two parallel groups. On April 24th, pufferfish obscurus (average size: 160g / tail) were stocked, the stocking density in the three-dimensional planting test pond was 800 / mu, and the stocking density in the pond for single-culture pufferfish was 1000 fish / mu; on May 27th, the three-dimensional In the breeding test ponds, each pond is stocked with shrimp seedlings of Penaeus vannamei, the stocking size of which is 0.8-1.0 cm, the salinity of shrimp seedlings is required to be desalinated below 2, and the stocking density of shrimp seedlings is 12,000 / mu. After more than 4 months of breeding, the growth of the fish has reached the exp...
