Abstract

The invention discloses a method for mixed culture of shellfish and black-spot grass shrimps. The method comprises the following steps of breeding shellfish fries: after water is sent into a culture pond, cleaning and disinfecting the pond, and breeding the shellfish fries after 5 days; after the shellfish fries are sent into the culture pond, when the water temperature reaches 5 DEG C, applying 1 to 2kg of cream fertilizer containing algae species per mu, so as to improve water fertilizing; when the water temperature exceeds 18 DEG C in the culture pond, breeding black-spot grass shrimp fries: when the black-spot grass shrimp fries are bred, fertilizing the water 2 days in advance, so as to enable the water to display a light yellow or light green color; when the length of each black-spot grass shrimp fry is not greater than 5cm, feeding with the cream fertilizer every 4 to 5 days; when the length of each black-spot grass shrimp fry is greater than 10cm, feeding with a synthetic bait according to 7 to 10% of shrimp weight each day; fertilizing the water every 15 days, and cultivating diatom. The method has the advantages that the mixed culture of shellfish and black-spot grass shrimps forms a mutualism ecological environment; the investment is little, the output is high, and the management is easy; the economic benefit of produced shellfish and black-spot grass shrimps is high.

Description

Shellfish and black speck grass shrimp polyculture method

Technical field

The present invention relates to technical field of aquaculture, especially, relate to a kind of shellfish and black speck grass shrimp polyculture method.

Background technology

Along with developing rapidly of Chinese national economy and steadily improving of living standards of the people, consumer's dietary structure occurs Great variety, for seafood products, such as ocean fishes, Penaeus seu panulirus, the consumption ratio of seashell products are heavily greatly increased.Due to demand not Breaking and increase, the demand that cannot meet daily life is fished in traditional fishery, and therefore, the cultivation of marine product has huge warp Ji benefit, then the quality how improving culturing marine products is the technical problem that industry is worth research with yield.

Summary of the invention

Present invention aim at providing a kind of shellfish and black speck grass shrimp polyculture method, to improve quality and the product of shellfish culture Amount.

For achieving the above object, the present invention provides a kind of shellfish and black speck grass shrimp polyculture method, comprises the following steps: annual Put shellfish seed the 1-2 month in a suitable place to breed: carry out, after culture pond water inlet, sterilization of cleaning up the pond, after 5 days, put shellfish seed in a suitable place to breed；Shellfish seed enters culture pond After, when water temperature reaches 5 DEG C, rich water strengthened by every mu of cream fertilizer using 1-2kg to have algae kind；At culture pond pond water temperature more than 18 DEG C Time, put black speck grass shrimp shrimp Seedling in a suitable place to breed: when putting black shrimp Seedling in a suitable place to breed, carry rich water the most again, making water colour is faint yellow or light green；Commonly Culture pond every mu culture pond puts 5000-6000 tail black speck grass shrimp shrimp Seedling in a suitable place to breed, has the culture pond every mu of oxygen supplement to put 10000-15000 in a suitable place to breed Tail black speck grass shrimp shrimp Seedling；Fertile at fail to grow up cream of throwing something and feeding in 5 time of black speck grass shrimp shrimp Seedling body, within every 4-5 days, throw something and feed once, when grass shrimp body Long more than 10 after, every day throws something and feeds synthetic diet by 7% the 10% of shrimp body weight；Meanwhile, every 15 days rich water once, cultivates diatom, Shellfish is made to have sufficient bait to ingest.

Further, described shellfish seed includes Sinonovacula constricta, Conch Meretricis seu Cyclinae and flower clam；Described Sinonovacula constricta every square metre puts 200-350 in a suitable place to breed , described Conch Meretricis seu Cyclinae every square metre puts 600-700 grain in a suitable place to breed, and described colored clam every square metre puts 600-700 grain in a suitable place to breed.

Further, when putting described black speck grass shrimp shrimp Seedling in a suitable place to breed, culture pond water does not surpasses with black speck grass shrimp shrimp Seedling Seedling bag water temperature difference Cross 2 DEG C, when Seedling bag water temperature is more than 2 DEG C with culture pond water temperature difference, first Seedling bag will be put into culture pond endoadaptation and put again for 2-3 hour Seedling, the salinity of the water in described Seedling bag differs with the salinity of culture pond water less than 5/1000ths.

The method have the advantages that

Shellfish is raised together with black speck grass shrimp, utilizes the ecological and biological characteristics such as water layer, feeding habits that shellfish and black speck grass shrimp perched Property, forms the ecological environment of a kind of Mutualism, has less investment, output advantage high, manageable, simultaneously output shellfish and black Speckle grass shrimp high financial profit.

Detailed description of the invention

Hereinafter embodiments of the invention are described in detail.

The preferred embodiments of the present invention provide a kind of shellfish and black speck grass shrimp polyculture method, comprise the following steps: annual Put shellfish seed the 1-2 month in a suitable place to breed: carry out, after culture pond water inlet, sterilization of cleaning up the pond, after 5 days, put shellfish seed in a suitable place to breed；Shellfish seed enters culture pond After, when water temperature reaches 5 DEG C, rich water strengthened by every mu of cream fertilizer using 1-2kg to have algae kind；At culture pond pond water temperature more than 18 DEG C Time, put black speck grass shrimp shrimp Seedling in a suitable place to breed: when putting black shrimp Seedling in a suitable place to breed, carry rich water the most again, making water colour is faint yellow or light green；Commonly Culture pond every mu culture pond puts 5000-6000 tail black speck grass shrimp shrimp Seedling in a suitable place to breed, has the culture pond every mu of oxygen supplement to put 10000-15000 in a suitable place to breed Tail black speck grass shrimp shrimp Seedling；Fertile at fail to grow up cream of throwing something and feeding in 5 time of black speck grass shrimp shrimp Seedling body, within every 4-5 days, throw something and feed once, when grass shrimp body Long more than 10 after, every day throws something and feeds synthetic diet by 7% the 10% of shrimp body weight；Meanwhile, every 15 days rich water once, cultivates diatom, Shellfish is made to have sufficient bait to ingest.Shellfish is raised together with black speck grass shrimp, utilizes water layer, feeding habits etc. that shellfish and black speck grass shrimp perched Ecology and biological characteristics, form the ecological environment of a kind of Mutualism, have less investment, output advantage high, manageable, Output shellfish and black speck grass shrimp high financial profit simultaneously.

Preferably, it is ensured that the normal growth of shellfish, described shellfish seed includes Sinonovacula constricta, Conch Meretricis seu Cyclinae and flower clam；Described Sinonovacula constricta is every Square metre putting 200-350 grain in a suitable place to breed, described Conch Meretricis seu Cyclinae every square metre puts 600-700 grain in a suitable place to breed, and described colored clam every square metre puts 600-700 in a suitable place to breed Grain.
