Problems solved by technology

The current trend of climate warming has created favorable conditions for the expansion of mangroves to higher latitudes. On the other hand, Penaeus vannamei farming is a pillar industry in the southeast coast, and the wastewater from shrimp farming is directly discharged without treatment, causing the surrounding water to become rich. Nutritization, destruction of aquaculture water sources, pollution of offshore ecological environment

Embodiment Construction

[0025] Experimental design: The mudskipper breeding experiment was carried out in the southern part of Yongxing Waiken, Longwan District, Wenzhou City. This area has a mid-subtropical monsoon climate, with annual sunshine of 1442-2264h and average annual rainfall of 1113-2494mm, which is suitable for mudskipper farming. 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‰. Build ridges around the 2 breeding ponds. The ridge surface is 0.6m higher than the beach surface, and the width is 0.5m. The ridge is solid and watertight. Dig ditches with a width of 1.0 m and a depth of 0.4 m inside the ridge. After use, dredge them regularly to prevent silt from clogging.

[0026] Experimental pond: prepare the ground for ridges, and the ridges are in a north-south direction, and plant 2-year-old candela on the surface of the ridges. In this culture method, shrimp pond mud is used as the base fertilizer, and...

Abstract

The invention provides a method for breeding boleophthalmus pectinirostris in a coastal reclamation mudflat by utilizing natural baits obtained through proliferation of nutrient sources in penacus orientalis breeding wastewater. The breeding benefits are remarkable, a mangrove forest purifies water at the same time, the method is a sustainable development breeding method, and a solution is provided for utilizing the reclamation mudflat in the southeast coastal area and relieving sharp contradiction between mangrove forest and mudflat breeding.

Description

technical field [0001] The invention relates to a method for coupling planting and breeding on reclamation tidal flats in coastal areas, specifically a method for creating mangrove aquaculture habitats on reclamation tidal flats by using a ridge method, and using nutrient sources in prawn breeding wastewater to multiply natural bait to breed mudskippers. Background technique [0002] The giant mudskipper (Boleophthalmus pectinirostris) belongs to the Mudskipper family of the Goby suborder. It is a warm-water, wide-temperature, and wide-saline fish. It lives in the intertidal mud flats and mangrove areas of estuaries and harbors. It is sold well in Zhejiang and Fujian. , Guangdong, Taiwan, Japan and other places, it is a tidal flat economic fish with broad market prospects. The cultivation of mudskippers in the southeast coast started in the 1980s, and then developed rapidly. By 2004, the cultivation area in the southeast coast had reached 13,000hm 2 . In recent years, land...
