Problems solved by technology
Since these clamworm species cannot do without sediment as habitat substrate in the breeding process, the harvesting process mainly depends on manual excavation, which is labor-intensive and consumes a lot of labor. Biodiversity in farming areas
This kind of excavation process is easy to cause damage to clamworms, which reduces the yield of commercial clamworms
Large labor costs and the proportion of defective products increase the cost of clamworm breeding. Therefore, this traditional breeding method has great limitations and will inevitably hinder the development of clamworm breeding industry

Embodiment 1
[0017] Selection of habitat matrix balls: According to the existing specifications of clamworm seedlings, for clamworm seedlings with an average weight of about 0.4g, glass balls with a diameter of 7mm are used as habitat matrix balls. When the glass balls of this specification are stacked together , and the gaps between them can easily allow the clamworms to pass through.
[0018] The laying of the habitat matrix: the habitat matrix uses a mixture of habitat matrix balls and sediment. The principle is that the volume of sediment does not exceed the habitat matrix ball. The volume of sediment: the volume of glass balls = 1:3, pre-mixed before laying, and the laying is complete The depth of the total habitat substrate is about 8cm, which is in line with the principle that the small size clamworm uses a shallower habitat substrate, and the larger size clamworm uses a deeper habitat substrate.
[0019] Stocking and management of seedlings: according to seedling specifications, se...

Abstract
A clamworm breeding method belongs to the technical field of aquaculture. The clamworm breeding method comprises the steps of selection of habitat medium balls, laying of habitat mediums, seed free ranging and management and harvest. The determining principles of the habitat medium balls comprise that when the habitat medium balls are stacked into a whole, gaps among the balls allow clamworms to pass through easily; when the average weight of the clamworms is less than 0.5 g, the habitat medium balls with a diameter of 3 mm-6 mm are selected, when the average weight of the clamworms is 0.5 g-1.0 g, the habitat medium balls with a diameter of 6 mm-9 mm are selected, when the average weight of the clamworms is 1.0 g-2.0 g, the habitat medium balls with a diameter of 9 mm-15 mm are selected, and when the average weight of the clamworms is more than 2 g, the habitat medium balls with a diameter of 15 mm-20 mm are selected. The clamworm breeding method avoids the negative factors generated in the prior art when only sand serves as breeding mediums, so that harvest can be facilitated and accelerated, and the labor cost can be effectively saved; the clamworm breeding method can be applied under the condition of indoor industrialized breeding as well as in areas such as outdoor ponds and shallow sea.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a method for growing clam worms. Background technique [0002] The clam worm is a benthic marine organism with high economic and nutritional value, and mainly feeds on sediments and animal and plant debris. In recent years, the scale of clam worm breeding has been continuously expanding, and the main cultured species are clam worms with double teeth, clam worms with multiple teeth, clam worms, and rock worms. Since these clamworm species cannot do without sediment as habitat substrate in the breeding process, the harvesting process mainly depends on manual excavation, which is labor-intensive and consumes a lot of labor. biodiversity in the farming area. This excavation process is easy to cause damage to the clamworm, which reduces the yield of the commodity specification clamworm. Larger labor costs and the proportion of defective products increase the cost of clam worm b...
