Embodiment 1

[0042] In a certain farm, mixed cultivation of clams and white prawns is carried out, and a high-yield method for cultivating meretrix meretrix and white prawns in ponds is as follows:

[0043] 1. Breeding pond preparation: carry out dredging transformation on an 8-acre pond, with a slope of about 45゜, surrounding platforms, two upper and lower platforms, the upper platform is 4m wide, and the lower platform is 4-6m wide. Drainage system, set up a breeding machine; after the normal water storage of the pond, the water depth of the upper platform is 60cm, the water depth of the lower platform is 3m, and the water depth of the deep tank is 4m;

[0044] 2. Sprinkle the whole pond with quicklime. After 15 days of disinfection, tie a 100-mesh mesh bag at the water inlet and enter the seawater to a water depth of 80-90cm. Apply photosynthetic bacteria to maintain water quality, and apply bio-organic fertilizers for initial fertilizer and water, and cultivate basic biological bait;

Abstract

The invention relates to a pond polyculture high-yield method for red-shell meretrix meretrix and exopalaemon carinicauda holthuis. The method comprises the following steps: a deep water tank and a peripheral platform are dug in the middle of a pond, and water is normally stored in the pond; after disinfection, water quality maintenance is carried out, and initial water fertilization is carried out; in March, seeding of the red-shell meretrix meretrix is completed; fertilizing water mainly in early May, and putting parent exopalaemon carinicauda holthuis from late May to early June; and before the first batch of shrimp seeds grow to 2.5 cm in the current year, the aquatic water body is stably yellow green or yellowish brown mainly by adjusting the algal facies of the water body, after the shrimp seeds grow to 2.5 cm to 3 cm, pellet feed is fed, and feeding is enhanced in September to October. According to the method, by setting the pond stocking sequence and time of the meretrix meretrix and the exopalaemon carinicauda holthuis, the win-win situation of breeding of the meretrix meretrix and the exopalaemon carinicauda holthuis is achieved through ecological niche complementation, close matching of varieties and breeding management operation of key nodes, and the purpose of high yield is achieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a high-yield method for polyculture of red-shelled clams and white prawns in ponds. Background technique [0002] Exopalaemon carinicauda Holthuis has been artificially cultured in coastal areas of more than 300,000 mu in my country, and has become the main characteristic species of pond culture in coastal tidal flat areas. It has become an important economic shrimp species in pond culture in Jiangsu, Zhejiang and other provinces. The "Qidong model" of mixed culture of white shrimp and Portunus trituberculatus is the most common. Since the 1990s, the mixed culture of white prawns and swimming crabs has been prosperous for more than 20 years. From the best period, the average yield of white prawns was 480 catties per mu, and that of swimming crabs was 50 catties per mu. The output is 250 jin and 20 jin, or even less. The high input and high output of this model has ...
