Embodiment 1
[0029] The invention provides a method for constructing a fish fry cultivation pond based on a geomembrane, comprising the following steps:
[0030] The pond mouth is 5 mu, and the pond mouth is repaired with mechanical equipment. After the repair, the depth of the pond is 2m, and the slope ratio is 1.5. The 50S geomembrane is laid on the bottom of the pond by welding, extending to 1.5m of the pond stem. And compact the pond stem with soil. After the reconstruction of the pond mouth, the Yellow River carp is mainly raised, and 800 carp species / mu (8 fish / jin) are put in, with 100 silver carp / mu (5 fish / jin) and silver carp 200 / mu (6 fish / jin) According to 3% of the total weight of farmed fish, artificial feed with a protein content of 28% is fed. The pond water is drained at the end of April of the following year, and the commercial fish caught are sold or divided into ponds, and the ponds are sun-dried to sterilize. Before the fish fry are splashed into the pond, the breedin...
Embodiment 2
[0032] The invention provides a method for constructing a fish fry cultivation pond based on a geomembrane, comprising the following steps:
[0033] The pond mouth is 7 mu, and the pond mouth is repaired with mechanical equipment. After the repair, the depth of the pond is 2.5m, and the slope ratio is 1.3. The 50S geomembrane is tiled on the bottom of the pond by welding, extending to 1m of the pond stem. And compact the pond stem with soil. After the reconstruction of the pond mouth, grass carp is mainly raised, and 1000 grass carp species / mu (3 tails / jin) are put in, with 30 silver carp / mu (3 fish / jin), silver carp 100 / mu (4 fish / jin), 150 crucian carp / mu (5 tails / catties), 10 herring / mu (2 tails / catties), artificial compound feed with 30% protein content according to 3% of the total weight of farmed fish, and the pond water will be pumped at the end of April next year After drying, the caught commercial fish will be sold or divided into ponds, and the ponds will be sun-dried...
Embodiment 3
[0035] The invention provides a method for constructing a fish fry cultivation pond based on a geomembrane, comprising the following steps:
[0036] The pond mouth is 10 mu, and mechanical equipment is used to repair the pond mouth. After the repair, the depth of the pond is 2.5m, and the slope ratio is 1.5. The 50S geomembrane is tiled on the bottom of the pond by welding, extending to 1m of the pond stem. And compact the pond stem with soil. After the reconstruction of the pond mouth, bream is mainly raised, and 1800 bream fry / mu (10 fish / jin) are put in, with 40 silver carp / mu (3 fish / jin) and 100 silver carp / mu (3 fish / jin) , crucian carp 200 / mu (10 / catties), fed with 3% of the total weight of the cultured fish and artificially fed compound feed with a protein content of 30%, drained the pond water at the beginning of March of the following year, and sold or distributed the commercial fish caught After the pond, the pond is sun-dried to sterilize. Before the fish fry are s...
