Background

China is a large seawater culture country, shellfish culture occupies a dominant position in the whole seawater culture industry, wherein the yield of mudflat shellfish accounts for about 20 percent of the total seawater culture yield of China. The existing shallow sea tidal flat area of China is about 2 hundred million mu, the utilization rate is not more than 20 percent at present, and the development space for increasing and breeding the tidal flat shellfish is large.

The mariculture can be roughly divided into three types, namely muddy, sandy muddy and sandy according to the difference of the bottom materials. The muddy bottom is mainly concentrated on coastal areas of Jiangzhe and Zhejiang Fujian, wherein the muddy bottom is mainly used for cultivating shellfish on the coastal areas of Zhejiang province, the cultivating area of the river-coastal shellfish razor clams, clams and clams exceeds 2.4 ten thousand hectares in 2019, and the shellfish cultivating yield is more than 40 ten thousand tons. The Jiangsu Fujian and other places also have a large number of muddy bottom mudflats and seawater ponds, and shellfish is taken as a main breeding variety.

In order to ensure that the released shellfish seedlings have a good inhabitation environment, the culture shoal surface must be trimmed and mashed before the shellfish seedlings are released in each year, and impurities such as enteromorpha are removed. The field Chengqing comprises the three steps of turning soil, harrowing soil and field ChengChengqing, so that a layer of soft mud with the thickness of 5cm is formed on the surface of the soil and is used as an adhesion base for shellfish life, and young shellfish can easily enter the mud to live. The mud turning operation can form a layer of attaching base on the surface of the mud, so that young shellfish which just enter benthic life can easily enter the mud to live, and can promote organic matters in the mud to be dissolved in water to realize water fertilization.

The enteromorpha is natural wild green algae living in offshore mudflats, has extremely strong natural reproductive capacity, increases the air temperature when beginning to spring, can form green tide when the enteromorpha grows explosively, leads aquatic products such as shellfish to die due to oxygen deficiency, and therefore the enteromorpha in a mudflat pond needs to be removed so as not to influence shellfish culture.
