Embodiment 1

[0019] The first step, the preparation of garlic juice: Weigh the fresh garlic according to the water body, use a crusher to crush the garlic into pieces, and then remove the garlic skin. Then adopt refiner to pulverize fragments, filter with 300 mesh sieve silk screens, continue to crushed residues as in the refiner, through 3 times, almost all crushed residues all pass through 300 mesh screens silk screens, make garlic juice.

[0020] The second step, the application of garlic in the large-scale cultivation of Philippine clams: during 2002-2006, during the entire process of large-scale cultivation of Philippine clams, garlic juice was put into large-scale cultivation of Philippine clams at a concentration of 6 mg / L. In the nursery culture pond, throw something to feed once every 3 days, all press garlic juice to press the throw something to feed of 6mg / L every time. Appropriate garlic juice concentration effectively accelerates the growth rate of larvae, improves the surviva...

Embodiment 2

[0022] The first step, the preparation of garlic juice: Weigh the fresh garlic according to the water body, use a crusher to crush the garlic into pieces, and then remove the garlic skin. Then adopt refiner to pulverize fragments, filter with 300 mesh sieve silk screens, continue to crushed residues as in the refiner, through 3 times, almost all crushed residues all pass through 300 mesh screens silk screens, make garlic juice.

[0023] The second step, the application of garlic in the larval stage of Philippine clam: in 2003-2004, put garlic juice into the indoor artificial breeding pond to a concentration of 6-8mg / L, and then regularly put garlic juice to maintain the concentration in the pond Within the range of 6-8mg / L, the concentration can effectively increase the survival rate of larvae by 20-30%, the rate of metamorphosis by 25-35%, and the growth rate by 10-15%.

Embodiment 3

[0025] The first step, the preparation of garlic juice: Weigh the fresh garlic according to the water body, use a crusher to crush the garlic into pieces, and then remove the garlic skin. Then adopt refiner to pulverize fragments, filter with 300 mesh sieve silk screens, continue to crushed residues as in the refiner, through 3 times, almost all crushed residues all pass through 300 mesh screens silk screens, make garlic juice.

[0026] The second step, the application of garlic in the stage of Philippine clam spat: during 2003-2004, during the cultivation stage of Philippine clam spat, garlic juice was put into the indoor artificial culture pond to a concentration of 8mg / L, and it was regularly injected to make Maintaining the concentration in the pond below 8mg / L can effectively increase the survival rate of spat by 40-50%, and increase the growth rate by 15-25%.

Abstract

The invention relates to a method for applying garlic to large-scale ecological breeding of ruditapes philippinarum; more particularly, 6-8mg / L of garlic juice is adopted in the course of breeding, thus the survival rate and the metamorphosis rate of larvae can be increased by 20-30% and 25-35% respectively, the growth of the larvae and juvenile mollusk can be promoted, the growth rate of the larvae and the juvenile mollusks are respectively raised by 10-15% and 15-25%, the survival rate of the juvenile mollusks is increased by 35-50%, meanwhile, the garlic juice has a good effect on preventing diseases. The application method has the advantages that the former fishing medicines such as antibiotics are replaced by the garlic juice, the real indoor large-scale ecological breeding is realized, and the application method is an effective means for producing ecological seedlings. The application method is characterized by simple operation, convenience and feasibility, which can be appliedto the large-scale ecological breeding of ruditapes philippinarum, and effectively increase the yield of the ecological seedlings of ruditapes philippinarum by 50-60%.

Description

technical field [0001] The invention relates to an application method of garlic in large-scale ecological seedling cultivation of philippine clams, specifically using garlic juice of suitable concentration to prevent and treat diseases in seedling cultivation, thereby enhancing the stress resistance of larvae and juvenile shellfish, and increasing the metamorphosis rate of larvae , is a feasible method for mass production of ecological seedlings. Background technique [0002] my country is a big breeding country for Ruditapes plippinarum. At present, the world's annual aquaculture output of more than 2 million tons mainly comes from mainland China. However, the serious shortage of seedlings and the invasion of diseases have become the "bottleneck" that restricts the further development of Philippine clam culture in my country. Therefore, it is imperative to carry out indoor full artificial seedling cultivation of Philippine clams. However, indoor artificial nursery is carr...
