Problems solved by technology

However, the fish fry cultivation method that relies on soy milk produces a relatively single type of plankton, and the single bait organisms cause the fish to eat, which will destroy the ecological balance of the pond and bring diseases to the fish; in addition, improper use of soybean milk will also pollute the fish. Water quality affects the living environment of fry and reduces the survival rate of fry; in addition, the soybean milk cultivation method needs to go through steps such as buying beans, soaking beans, grinding beans, and artificially splashing, which consumes more financial, material and manpower

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...

Abstract

The invention relates to a method for constructing a geomembrane-based fry cultivation pond, which belongs to the technical field of aquaculture. The method comprises the following steps: (1) geomembrane laying; (2) commercial fish cultivation; (3) clear pond and bait Biological cultivation; (4) fry cultivation; (5) recycling of geomembrane ponds. The invention uses the geomembrane to accumulate organic fertilizers such as residual bait and metabolites produced in the commercial fish breeding process, cultivates water quality, relies on the ecological cycle of the pond itself, promotes the reproduction of natural biological bait, and solves the biological bait problem in the fish fry cultivation process , improve the survival rate of fry and effectively reduce economic costs, has the advantages of saving time and effort, high success rate, etc., and has obvious ecological and economic benefits.

Description

technical field [0001] The invention relates to a method for constructing a fish fry cultivation pond based on a geomembrane, and belongs to the technical field of aquaculture. Background technique [0002] Biological bait is a key factor affecting the survival rate of aquatic economic animal seedlings. The bait organisms required for freshwater aquaculture mainly include zooplankton and phytoplankton. Compared with other feeds, biological bait not only has higher food value (balanced and rich in nutrition, especially rich in trace elements and unsaturated fatty acids, etc.), but also has the advantages of low cost, can enhance the disease resistance of breeding objects, and does not pollute water quality. . The traditional method of cultivating fry is to feed soy milk in earthen ponds. On the one hand, the fry will eat a small amount of soy milk. On the other hand, the soy milk can be used as a fertilizer in the pond to promote the reproduction of plankton in the breeding ...
