Problems solved by technology

In recent years, a large number of coastal tidal flats have been reclamated, the aquaculture area has been continuously reduced, and the cost of pond aquaculture has been continuously increased, resulting in a decline in the economic benefits of mudskipper aquaculture

Embodiment Construction

[0028] Experimental design: The large mudskipper culture experiment was carried out in the southern part of Yongxing Weiken, Longwan District, Wenzhou City. This area has a mid-subtropical monsoon climate, the annual sunshine is 1442-2264h, the average annual rainfall is 1113-2494mm, and the annual water temperature is 6-32℃. Suitable for large mudskipper breeding. The area of ​​the two breeding ponds is 2 mu, the bottom of the pond is flat, the mud is soft mud, and the salinity is about 10‰-20‰. A ridge was built around the two breeding ponds. The ridge surface was 0.6 meters higher than the beach surface, and the width was 0.5 meters. The ridge was solid and watertight. Dig a ditch with a width of 1.0 meters and a depth of 0.4 meters on the inner side of the ridge. After use, it should be dredged regularly to prevent silt blockage.

[0029] Test pond: ridges were prepared and the ridges were in a north-south direction, and 3-year-old autumn eggplants were planted on the rid...

Abstract

The invention provides a method for cultivating large mudskippers by using nutrient sources in prawn breeding wastewater to multiply natural bait on coastal reclamation tidal flats. The breeding benefits are remarkable. At the same time, mangroves purify the water quality, which is a sustainable breeding method and is an important method for reclamation in southeastern coastal areas. The utilization of tidal flats and alleviating the sharp contradiction between mangroves and tidal flat farming provide a solution. The core idea of ​​the technical solution of the present invention is to develop a mangrove culture model suitable for mudskippers while ensuring the water purification effect of mangrove wetlands, to improve the economic benefits of mangroves, thereby promoting the process of transplanting mangroves to high latitudes.

Description

technical field [0001] The invention relates to a method for cultivating giant mudskipper in high-latitude mangrove areas, specifically a method for high-latitude transplanting of mangroves coupled with giant mudskipper breeding based on shrimp farming wastewater utilization technology. Background technique [0002] Mangroves are one of the most productive ecosystems in the world, mainly located in tropical and subtropical bay estuaries. It has important ecological functions such as coastal protection, maintaining biodiversity and regulating regional climate change, and has an irreplaceable role in terrestrial forests. The region exports a large amount of organic matter. However, in the past 50 years, more than half of mangrove forests have been cut down globally, especially in Asian countries. my country is no exception. In the 1950s, the area of ​​mangroves in my country was about 400-420km. 2 , dropped sharply to 213km by 1986 2 . The natural distribution of mangrove...
