Abstract

The invention relates to a method for breeding abalone fry artificially. The method comprises the following steps: artificially selecting fry individuals which are healthy, undamaged, have stout and strong physique, obvious male and female gonad, as well as the size of more than 6 centimeters; putting the fry individuals in filtered sea water with water temperature in a pond of between 20 and 25 DEG C, the PH value of between 7.5 and 7.8, and the proportion of between 1.02 and 1.05; feeding parent abalone with seaweeds twice a day; breeding the parent abalone for 120 to 140 days so that the parent abalone reach sexual maturation, and allowing the parent abalone to naturally lay and discharge sperms; and directly performing still water incubation on a germ cell in a water tank. The scales of the germ cell are about between 450 and 640 per square centimeters; when the water temperature is between 24 and 25 DEG C, the germ cell grows into a larva after about two days; and healthy lavae are collected to transfer into a culture pond to breed a larva abalone. The method can realize the scale artificial breeding of the abalone fries, and has the advantages of low breeding cost, high fry survival rate and so on.

Description

Artificial method for breeding abalone fry
[technical field]
The present invention relates to a kind of artificial method for breeding abalone fry.
[technical background] abalone is a kind of famous and precious marine product, is listed in one of extra large eight delicacies.Abalone fry is had relatively high expectations to the temperature of breeding water body, salinity etc., and its seed breeding has certain difficulty, the domestic before this precedent that the propagation in scale success is not arranged as yet.
[summary of the invention]
The object of the present invention is to provide a kind of large-scale artificial method for breeding abalone fry.
Above-mentioned purpose of the present invention is achieved in that
A kind of artificial method for breeding abalone fry, concrete steps:
A, artificial selection health can't harm, physique is stout and strong, foot movement is quick, the male and female sexual gland is significantly individual big or small more than 6 centimetres, throw in the pool water within temperature at 20-25 ℃, the pH value is 7.5-7.8, and proportion is in the filtering sea of 1.02-1.05, gives twice of every day the close Bao seaweeds of throwing something and feeding; Through cultivation in 120-140 days, close Bao is the accessibility maturation just, made it that natural spawning row is smart in the tank that 60-140 centimetre of filtering sea is housed;
Carry out the hydrostatic hatching in b, the direct tank of fertilized egg.About every square centimeter of 450-640 of the scale of fertilized egg, in the time of water temperature 24-25 ℃, grow up to larva about two days;
C, the healthy young is collected, change culture pond over to and begin young Bao Peiyu.
No matter take which kind of method to culture, the breeding density of young Bao is all unsuitable excessive, otherwise will influence survival rate and growth rate.Adopt cage culture, every square metre of water surface can be put about 6000 of the young Baos of long 5 millimeters of shell in a suitable place to breed.
What of quantity of exchanged water can directly have influence on the ingesting of young Bao, growth and survival rate.In the ordinary course of things, along with the increase of quantity of exchanged water, the per day growth rate of young Bao is also and then accelerated.For making the dissolved oxygen in the water be not less than 5 milliliters/liter, before long 6 millimeters of the average shell of young Bao, the streamflow of every day should be no less than 4 times that cultivate water body, surpasses 6 millimeters and should be no less than 6 times.
Cultivate period young Bao, the tender lobate green alga of children of can throwing something and feeding.The young Bao synthetic bait of ingesting is faster than consumer organism bait growth rate, can reach big specification before surviving the winter, and improves overwintering survival rate.The daily ration, feeding quantity of synthetic diet every day is the 1%-3% of young Bao body weight.
The present invention can realize the large-scale artificial breeding abalone fry, has that the cost of breeding is low, the seedling percent advantages of higher.
[embodiment]
A, artificial selection healthy harmless, physique is stout and strong, the significantly individual size of male and female sexual gland is more than 6 centimetres, throws in the pool water within temperature at 25 ℃, pH value is 7.5, proportion is in 1.02 the filtering sea, twice of every day is to the close Bao seaweeds of throwing something and feeding; Through cultivation in 120 days, close Bao is the accessibility maturation just, made it that natural spawning row is smart in the tank that 60 centimetres of filtering seas are housed;
Carry out the hydrostatic hatching in b, the direct tank of fertilized egg.About 540 every square centimeter of the scales of fertilized egg, when 25 ℃ of water temperatures, grow up to larva about two days;
C, the healthy young is collected, change culture pond over to and begin young Bao Peiyu.
