Problems solved by technology

[0003] Since 1999, we have introduced geoduck five times (1999, 2001, 2002, 2010, 2011) from the United States and Canada for artificial breeding and breeding experiments. ) The output is stable at 20,000-30,000 grains/m2, but the breeding technology has not achieved

Embodiment Construction

[0014] For further illustrating the present invention, specifically illustrate in conjunction with following examples:

[0015] 1. Mussel cultivation

[0016] From February to March every year, 20-30 geoducks (individual weight about 1Kg) are imported from the United States or Canada. The temperature is controlled artificially in the nursery room, and bait is fed. The maturation can be stimulated for 10-12 days, and the larvae can be stimulated to spawn after 20-20 days. After 22 days of cultivation, the bottom habitat crawls and metamorphoses into spat, and the spat can be cultivated into shellfish seedlings with a shell length of more than 3mm after about 50 days.

[0017] 2. Facilities

[0018] The breeding pond adopts ordinary cement pond (such as the 5×1.4×1m=7m we use 3 ), divided into upper and lower layers by hollow bricks, two inflatable pipes are laid on the lower layer, and breeding boxes are placed on the upper layer (0.7×0.48×0.27=0.33m 3 ), the breeding box ad...

Abstract

The invention relates to a method for indoor geoduck culture. By the method, the geoduck native to pacific coasts of Australia and America can be cultivated indoors at north coasts of China, and 3-5 years originally taken for geoduck individuals to grow to one pound in a sea area are shortened to less than 2 years taken for the geoduck individuals to grow to about 0.5kg. The method includes: burying geoduck seeds in substrate for dwelling, using inflating tubes to continuously fill air upwards so as to bring metabolites, residual bait, dirt and the like in the substrate to the surface of each cage, discharging the metabolites, residual bait and dirt with water flow. Therefore, the water environment for geoduck in the cages is constantly kept clean. By means of manual feeding, inflated pollution discharge, growth water temperature control, regular cage inverting for seed screening and the like, the geoduck individuals cultured indoors grow to 0.5kg in two years, and the yield per unit area reaches 10-12kg/m<2>.

Description

technical field [0001] The invention relates to the technical field of aquatic animal breeding, in particular to a geoduck indoor breeding technology. Background technique [0002] Since the 1990s, the United States and Canada exported 4,000-3,000 tons of geoduck to Asia each year, worth about 100 million US dollars, of which 70-80% were exported to Hong Kong and the southeast coast of my country. In the 21st century, the export volume of North America has gradually decreased. The current annual export volume is only about 2,000 tons, and the price per pound has risen from US$10-15 in the past to US$30-40. Therefore, the economic significance of introducing geoduck to China for artificial breeding is very huge. [0003] Since 1999, we have introduced geoduck five times (1999, 2001, 2002, 2010, 2011) from the United States and Canada for artificial breeding and breeding experiments. ) The output is stable at 20,000-30,000 grains / m2, but the breeding technology has not achie...
