Mud polyculture technology for pond polyculture
Large yellow croaker, American redfish, black silk, and cockroaches are the main targets of current marine aquaculture and have higher economic returns. In recent years, there have been many reports on the breeding of single species or the polyculture of two varieties. However, research on the polyculture of "three fish and one shellfish" has not been reported. For this purpose, the author conducted a polyculture trial of “Three Fish and One Shellfish†in the Shuangpantu Ecological Fisheries Demonstration Park in Ninghai, Ningbo, Zhejiang Province, from April 3 to December 10, 2002, and obtained good economic benefits. More obvious promotion value. The relevant technical measures of the test are summarized below for reference.
1. The pond condition test pool is an east-west rectangular pond with a length-to-width ratio of 3:1 and an area of ​​20 mu. The sediment is sandy, the bottom of the pond is flat, and there is less silt, and the effective depth is 1.5-2.1 meters. Into the drainage system Relatively independent, each tide can enter and drain 13. 14 days, the water quality in the open sea area is good, there is no pollution source nearby.
Second, pre-culture preparation
1. Whole pond and clear pond disinfection
(1) Repair gates, install flat nets, fences, etc., repair dams, leaks, and prepare common tools.
(2) Hydrocarbon finishing. An area of ​​3 acres, each specification length x width (20.30) meters x (3. 4) meters range, around the trench, painted surface deep-turning, crushing mud blocks, Fuping. The hydrocarbon field was made into a road shape, leaving a 50 cm wide and 30 cm deep ditch in the field.
(3) disinfection of clear ponds. 15.15 days before planting, drain the old water in the pond and use quicklime (dry method) to clean the pond. The dosage is 75-80 kg/mu. The whole pond is splashed and poured into the seawater for 30 centimeters and soaked for 3-5 days to discharge the seawater. Then enter the seawater 30--50 cm, bleaching powder (36% of available chlorine) whole pond spilled, so that the concentration of pool water to 10 grams / cubic meter, 2 days after discharge of disinfected seawater.
2. Cultivate basic bait
(1) After the clear pond is sterilized, install a 60 mesh or 40 mesh flat net (ie, inlet net) into the seawater 50--60 cm.
(2) The application of fermented chicken manure (granules may also), the amount of 15--20 kg / acre. The method is to hang the bag, and the woven bag is tied to the bamboo pole inserted in the pond and suspended in water, 1.5-2.5 kg/bag. After 7 days, start watering, 5 to 10 cm daily, and top-dressing once. The amount of chicken manure is 2 to 5 kg/mu, which is used to breed basic food organisms in the pond. After 10-15 days, the depth of pond water is 1, 0--1, 2 meters. The pond water is light yellow-brown or light yellow-green, and the seedlings are released when the transparency is about 30 centimeters.
3. The aerators are equipped with 4 aerators, each with a power of 1.5 kilowatts.
