Problems solved by technology

Due to the limitation of the breeding density of the planktonic larvae stage and the influence of metamorphosis attachment survival rate, the larval attachment density often appears insufficient, which reduces the utilization efficiency of sea cucumber cultivation pools and increases time, energy consumption and labor costs
The above problems have hindered the large-scale breeding industry development of tropical sea cucumbers

Embodiment 1

[0019] The method for multiple induced production and multiple batches of attachment to improve the utilization rate of tropical sea cucumber cultivation ponds and relatives comprises the following steps:

[0020] 1) Select 30 tropical sea cucumbers that are not affected by the law of lunar phase reproduction. During the breeding season of sea cucumbers, scatter the parent sea cucumbers on a clean and cool floor, dry in the shade for 2.0 hours, and put them in a clean 100L container In the barrel (spawning barrel), pump seawater along the wall of the barrel to impact the ginseng, add water to a depth of 1.0m, about 90L of seawater, wait for the sea cucumber to ovulate and ovulate; check whether the ginseng has ejaculated every 30 minutes, if found If the male ginseng is a male ginseng, put all the ejaculated male ginseng into a new seawater bucket in time, containing about 90L of seawater, as the sperm production bucket; Take 0.8L of seawater containing semen and add it to the...

Embodiment 2

[0029] The difference between embodiment 2 and embodiment 1 is that step 5) starts to take different operations:

[0030] 5) After checking that the attachment density in step 4) is too low, proceed to oxytocin cultivation. The parents in step 1) are cultured for 18 days, and the second artificial oxytocin is performed, and a total of 4.3 million fertilized eggs are obtained from the second oxytocin. The newly induced larvae are cultivated step by step, the method is as described in step 2), in the new water body, the planktonic phase cultivation method is carried out according to the step 2), until the newly cultivated planktonic larvae develop to the megapariae later stage, After concentrated collection, join step 4) in the water body that juvenile attachment density is insufficient, increase the attachment density of sea cucumber juvenile, guarantee that the attachment density of sea cucumber juvenile in 10 cultivation pools is increased to every 10 square centimeters, five ...

Abstract

The invention discloses a method for increasing the utilization rate of tropical sea cucumber cultivating pools and parent sea cucumbers by multiple times of induced labor and multiple batches of attachment. For the first time, the present invention utilizes the reproductive characteristics of certain tropical sea cucumber species that are not affected by the law of lunar phases, adopts the methods of multiple induced spawning, parallel or step-by-step cultivation, and successively supplements planktonic larvae for multi-batch attachment to water bodies with low attachment densities, improving the cultivation of water bodies. The density of attached seedlings in the medium can significantly improve the utilization rate of cement ponds for cultivating sea cucumber seedlings, and also significantly improve the utilization rate of tropical sea cucumber parents. By setting the density of the air chamber and adjusting the inflation intensity, the air pump is used to automatically and fully stir the floating water body, which greatly reduces the manpower consumption and improves the rate of attachment metamorphosis. The technical scheme of the invention can save time, manpower and energy consumption costs for large-scale cultivation of tropical sea cucumbers, and provide a technical basis for realizing artificial cultivation of tropical sea cucumbers and development and utilization of tropical sea cucumber resources.

Description

Technical field: [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for increasing the utilization rate of tropical sea cucumber cultivation pools and parent sea cucumbers by multiple times of induction and multiple batches of attachment. Background technique: [0002] Sea cucumber (Holothuroidea) is one of the eight treasures in the world and has important therapeutic value. my country is the most important consumer market. The global annual consumption of dried sea cucumbers is close to 40,000 tons, of which about 7,500 tons are imitation sea cucumbers cultured in low-temperature areas in my country, and almost all of the rest come from fishing tropical sea cucumbers. With the development of my country's economy, the demand for tropical sea cucumber will further increase rapidly. However, the characteristics of slow growth and long sexual maturity of sea cucumbers determine the long replenishment period for new individuals of s...
