Abstract
The invention discloses a parent haliotis discus hannai mature-promoting method capable of realizing early breeding, which can improve the fatness, egg laying amount, fertility rate, egg rate and fry survival rate of parent haliotis discus hannai, and comprises the following steps: selecting grown haliotis discus hannai, which is characterized by shells of at least 9 centimeters, gland maturity of 30 to 40 percent, G/L3 of more than 0.145, high activity and sorptive ability and no diseases as parent haliotis discus hannai, wherein the ratio of the number of male haliotis discus hannai to the number of female haliotis discus hannai is 80-100:500-1,000; and culturing the parent haliotis discus hannai in an early period, a middle period and a later period, wherein in the early period, the culture time is 40 to 50 days, the water temperature is 15 to 18 DEG C, and the parent haliotis discus hannai are fed with saline kelp; in the middle period, the culture time is 40 to 50 days, the water temperature is 17 to 22 DEG C and the partent haliotis discus hannai are fed with fresh kelp; and in the later period, the culture time is 20 days, the water temperature is 9 to 22 DEG C, and the parent haliotis discus hannai are fed with dried nori.
Description
Technical field:
The present invention relates to a kind of method of haliotis discus hannai Ino ahead of time seedling-cultivating, especially a kind ofly improve close Bao coefficient of condition, egg laying amount, fertilization rate, but the haliotis discus hannai Ino of the ahead of time seedling-cultivating of ovum rate and weed survival rate parent Bao accelerating method.
Background technology:
Haliotis discus hannai Ino (Haliotis discus hannai) is the important living marine resources of China, natural distribution in the Bohai Sea, the Huanghai Sea and waters, the sea of Japan, have the title of the soft gold in ocean, occupy first of the marine products eight delicacies, have very high nutrition and medical value.Contain Bao Lingsu as the abalone body, can the destruction of cancer cells metabolic process, improve immunity of organisms; Abalone shells is commonly called as the shell of seaear, can be used for the treatment of eyes relevant disease.Haliotis discus hannai Ino is one of kind of tool economic worth in the Bao Ke animal, also is the important mariculture shellfish of China's foreign exchange earning, along with the continuous expansion of the scale of breed, the demand of seed is risen year by year.
The natural propagation of haliotis discus hannai Ino be season mid-July in every year to mid-August, if adopting the close Bao Jinhang that catches physical maturity from the sea in breeding period grows seedlings, then may be because following former thereby can not guarantee that seed produces:
1. the variation of breeding weather in period, sea situation is unsteady bigger, can't catch close Bao from the sea;
2. be in a little less than the breeding adaptive capacity of close Bao of sensitive periods, cause survival rate low the artificial breeding environment;
3.7～August, water temperature surpassed 20 ℃, the larva main bait after the sinking metamorphosis--the breeding of-benthic diatom slowly and is easily worn out, and is difficult to satisfy the requirement of feeding of abnormal back larva;
4. winter is interim then, and the young Bao of being bred is too little because of individuality, vulnerable, and overwintering mortality is very high.
For avoiding the appearance of the problems referred to above, in actual production, often take the production method of close Bao artificial ripening.Existing close Bao artificial ripening method is to carry out close Bao accelerating at the beginning of annual 2 months, and the accelerating condition is raised to 20 ℃ of constant temperature for water temperature raises 1 ℃ every day; Bait is based on bright sea-tangle, and grazing rate is about 8%, and the later stage is 5%.The weak point of this accelerating method is that close Bao coefficient of condition reduces before growing seedlings, the impetigo that in the accelerating process, is easy to get, and (November) seed size is less than normal when emerging, on average between 1.5～2.0cm.
Summary of the invention:
The present invention provides a kind of and improves close Bao coefficient of condition, egg laying amount, fertilization rate in order to solve the above-mentioned technical problem of existing in prior technology, but the haliotis discus hannai Ino of the ahead of time seedling-cultivating of ovum rate and weed survival rate parent Bao accelerating method.
Technical solution of the present invention is: but a kind of haliotis discus hannai Ino of ahead of time seedling-cultivating parent Bao accelerating method is characterized in that carrying out as follows:
A. select in the one-tenth Bao of haliotis discus hannai Ino that shell length is at least 9cm, maturity of fish gonads is 3～4 one-tenth, G/L
3＞0.145, the strong and disease-free haliotis discus hannai Ino of vigor and sorptive force is as close Bao, and male Bao and the quantity of female Bao are than 80～100 in the close Bao: 500～1000;
B. be divided into and early stage, intergrade and three time periods of later stage cultivate close Bao, the cultivation time in early stage is 40～50 days, and water temperature is 15～18 ℃, the salt marsh sea-tangle of feeding; The intermediate rearing time is 40～50 days, and water temperature is 17～22 ℃, the bright sea-tangle of feeding; The cultivation time in later stage is 20 days, and water temperature is 19～22 ℃, the dried laver of feeding.
The present invention is divided into and early stage, intergrade and three time periods of later stage cultivates close Bao, and cultivate with different water temperatures, bait each period, and through 3～4 months cultivation, close Bao can maturation lay eggs.Not only realize the ahead of time seedling-cultivating of haliotis discus hannai Ino, close Bao coefficient of condition is better before also having guaranteed to lay eggs simultaneously, has improved close Bao availability, and egg laying amount height, fertilization rate are greater than 90%, and the ovum rate is greater than 80%.The weed survival rate height, (November) gained seed size accounts for 85～95% greater than 2.0cm when emerging, and 1.5～2.0cm accounts for 5～15%, accounts for below 5% less than 1.5cm, can be the raiser extensive healthy seedling is provided.
Embodiment:
A. begin to grow seedlings annual March 1～10, selects close Bao at the beginning of mid-October～11 month and go into the pond.Promptly in the one-tenth Bao of intensive culture, select that fast growth, specification are even, shell length more than 9cm, coefficient of condition is good, maturity of fish gonads is at 3～4 one-tenth, G/L
3＞0.145, vigor and sorptive force are strong, and the spiracle spacing is big, and wrinkle is obvious, and soft body and shell not damaged, disease-free haliotis discus hannai Ino are chosen 80～100 pieces of male Baos as close Bao according to per thousand square metres of seedlings growing areas, 500～1000 pieces of female Baos.
B. accelerating adopts interim temperature control to cultivate, and is divided into early stage, intergrade and three time periods of later stage.The cultivation time in early stage is 45 days, and water temperature is 17 ℃, the salt marsh sea-tangle of feeding; Cultivation time intergrade is 45 days, and water temperature is 19 ℃, the bright sea-tangle of feeding; The cultivation time in later stage is 20 days, and water temperature is 20 ℃, the dried laver of feeding.The same with prior art, in cultivating process, according to its situation increase and decrease bait feeding amount of ingesting, refresh the water periodically, fall the pond, remove the bait residue.
Through 100 days cultivation, close Bao can maturation lay eggs.Close Bao coefficient of condition is better before laying eggs, and has improved close Bao availability, and egg laying amount height, fertilization rate be greater than 90%, and the ovum rate is greater than 80%, the weed survival rate height.Through ovum artificial collection, collect seedling, peel off, the plane raises, 2,000,000 pieces in the good seed of final acquisition, the gained seed size accounts for 85～95% greater than 2.0cm, and 1.5～2.0cm accounts for 5～15%, account for below 5% less than 1.5cm, can be the raiser extensive healthy seedling is provided.
