Problems solved by technology

[0004] The technical problem to be solved by the present invention is: create a mangrove breeding habitat on the muddy beach in the southeast coastal area, use the nutrient source in the prawn breeding wastewater to cultivate natural bait to breed the large mudskipper, and at the same time, the mangroves purify the water quality, thereby realizing the high efficiency of the large mudskipper. Breeding can also reduce the emission of nitrogen pollutants, and it is a method of using "pasture farming" to protect the tidal flat environment

Embodiment Construction

[0032] The test area is located in the southern part of Yongxing Waiken, Longwan District, Wenzhou City, which 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.

[0033] Experimental design: In the test area, divide 2 aquaculture tidal flats with an area of ​​2 mu each, and divide them into test ponds and control aquaculture ponds. Experimental pond: The beach surface has a ridge structure, and mangroves are planted on the ridge surface to form 1-year-old candela. This model uses shrimp pond mud and tail water as nutrient sources to multiply natural bait, and finely manages and breeds large mudskippers. Control pool: flat beach surface, regularly drying the pool according to the traditional paradigm, applying benthic algae to grow compound nutrients, irrigated with natural seawater to grow algae, and breeding large mudskippers.

Abstract

The invention provides a mangrove breeding habitat on the muddy beach in the southeast coastal area, and uses the nutrient source in the prawn breeding wastewater to cultivate natural bait for cultivating large mudskippers. At the same time, the mangroves purify the water quality, thereby realizing high-efficiency breeding of large mudskippers and reducing nitrogen. Pollutant discharge is a method of "farming breeding" to protect the tidal flat environment.

Description

technical field [0001] The invention relates to a method for "pasture breeding" large mudskippers in coastal areas and suitable for forest tidal flats. Specifically, a mangrove breeding habitat is created on muddy tidal flats, and natural bait is used to cultivate large mudskippers with nutrient sources in prawn breeding wastewater. Mudskipper method. 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 r...
