A method for cultivating clam worms without water storage and saturated wet soil

Abstract

The invention discloses a perinereis aibuhitensis accumulated-water-free saturated wet soil cultivation method. The method is characterized by mainly including the following steps of designing a cultivation pond, putting seedlings, controlling the water content and the salt content of soil and casting feed. The key measure is that no water is accumulated in the cultivation pond in the cultivation process and saturated water with the proper salinity is contained in the soil by just spraying water. Compared with an existing cultivation manner, frequent water adding and water discharging are not needed, energy power consumption is relieved, the feed can be conveniently cast, the feed utilization rate is high, the feed cost and pollution to the environment are reduced, the cultivation density is large, the survival rate of perinereis aibuhitensis is high, the growth speed is high, and the cultivation productivity can be higher than 800 kg per mu.

Description

technical field [0001] The invention relates to a culture method for clam worm with no water storage and saturated wet soil, and belongs to the technical field of aquaculture. Background technique [0002] Perinereis aibuhitensis belongs to Nereididae (Nereididae) in zoological classification, Perinereis (Perinereis), commonly known as sea centipede, sea leech, etc., is mainly distributed in my country and is one of more than 80 species in China. Among the clam worms, the individual is larger, the growth is faster, and the biological resources are the largest. It is distributed in the mid-high tide beaches from south to north along the coast of my country. It is the main representative and dominant species of polychaetes in the intertidal zone. The most important species of artificial breeding and export earnings. Because it is widely used in food, medical care, aquaculture and fishing, the demand in domestic and foreign markets is very large, and there are often situations w...

Problems solved by technology

[0003] In order to make up for the lack of natural resources and meet the needs of domestic and foreign markets, artificial breeding has been carried out in many coastal areas of my country in recent years. At present, the main breeding methods are as follows: 1. Extensive farming in tidal flats, relying on natural bait, the yield per mu is generally not more than 20 kg; 2. Polyculture with other farmed animals such as shrimp, feed on residual bait and feces of shrimp, the yield per mu is generally not more than 50 kg; 3. Cultivation in earthen ponds, feeding artificial bait, 15 ~ 30d full change Water 1 time, due to the slow feeding process of the clamworm, some nutrients in the feed will be dissolved in the water, resulting in nutrient loss, and it is easy to cause deterioration of water quality and bottom quality, the yield per mu is generally about 300 kg; 4. Fill the cement pond with soil to store In aquaculture, artificial bait is fed and the water is changed every day. This method has a good breeding environment, and the yield per mu is generally more than 500 kg, and the highest can even reach 1,000 kg. The surrounding environment of the breeding area is heavily polluted
