I. Scope This standard stipulates the basic conditions, yields and pollution-free technical requirements for carp aquaculture.
This standard applies to carp pond culture.
Second, the choice of pond soil is loam, clay or sandy loam soil, good water retention performance. The pond size is 0.3-0.666ha, the pool is rectangular, the aspect ratio is 5:3, and the east-west direction. There are rivers, well water sources, and the water quality is pollution-free. The pond is installed into the drainage facility. The pool water depth is 2.5m.
III. Water Quality Indicators Implementation of Fishery Water Quality Standards GB1607--1989 PH Value 6.5---8.5 Dissolved Oxygen ≥4mg/L Ammonia Nitrogen<0.025mg/L Biochemical Oxygen Demand <5mg/L Others: Should Comply with GB1607---1989 Fisheries Water Quality Standard IV. Production
1. Specifications for stocking fish species, stocking capacity, adult fish size and yield Fish species specifications (g) Stocking amount (tail) Matching species fish size (g) Yield (kg)
鲢鳙 Program 1
Scenario 2
Scenario 3
2. The survival rate is above 95%.
V. Technical requirements
1. Water Quality Cultivation (1) Transparency 20--25cm
(2) Shi Jifei, Mushi Fermentation of human excrement or chicken manure 200 --- 500kg, or manure 500 --- 1000kg.
(3) Apply topdressing, see water fertilization, when the transparency is greater than 25cm, Mushi organic fertilizer 10----50kg, or inorganic fertilizer urea (N fertilizer) 2.5kg, phosphate fertilizer 1kg, organic fertilizer and inorganic fertilizer can be used interchangeably.
(4) Adjust water quality once every 10 days, injection and discharge volume 20---30cm.
2. The selection of fish species requires a healthy body, no damage, no disease, and neat specifications.
(1) Stocking time, divided into spring or fall stocking.
(2) Disinfection, before the fish is introduced into the pool, use 1010-6 malachite green or (1020) 10-6 potassium permanganate solution for 10-20 minutes.
(3) Before and after the fish species enter the pool, the water temperature difference cannot exceed 3
3. Disinfect the pond, before applying the basal fertilizer, disinfect it with quicklime water 150mg/mu, dry pond disinfection 75mg/mu.
4. Each 1.5-mu water surface is equipped with a 1.5-kilowatt aerator, and the oxygen-absorbing machine is used rationally. The dissolved oxygen is set to 4mg/L for the start-up indicator.
Sixth, pollution-free management measures
1. Water Quality (1) Fish should not be colored or smelled.
(2) The surface of the water is not marked with 6.1.3.
(3) Suspended matter, the artificially increased amount shall not exceed 10 mg/L, and suspended matter shall not have harmful effects on fish after it is deposited on the bottom.
2, disinfectant drugs, not 6.3 allowed to use in the fish body residual drug accumulation of drugs, such as 66 powder, DDT and so on.
VII. Feeding management 1. Establish a pond culture archive.
2. Adhere to the system of touring ponds, check whether the ponds are damaged, whether there is any change in water quality, whether the fish has floating heads, and if problems are found, promptly remedy. Check for dead fish, find dead fish, remove them immediately, check the cause of death, and take precautions. Measures.
3. Regularly adjust water quality to ensure the healthy growth of fish.
4, rational use of aerators, open at noon on sunny days, early morning on cloudy days, not open in the evening, floating head before the open, even the night of the Kam Yin rain open, the main growth season of fish persist in open every day.
