Abstract
The invention relates to a biological method for removing harpacticoida in a juvenile stichopus japonicus nursery pond and belongs to the field of aquaculture. Healthy penaeus seedlings with body lengths ranging from 0.4cm to 0.6cm are placed in the juvenile stichopus japonicus nursery pond, the number of seedlings is 11-50 per cubic water body, and the penaeus seedlings are one of fenneropenaeus chinensis seedlings, penaeus vannmei boone seedlings and penaeus japonicus seedlings. According to the biological method, the biological characteristics that the penaeus seedlings with the body lengths ranging from 0.4cm to 2cm ingest the harpacticoida and do not ingest and damage stichopus japonicus seedlings simultaneously are used, and the harpacticoida in stichopus japonicus seedling culture water bodies can be removed through the biological method. Compared with the existing drug method, the biological method has the advantages of being convenient to use, simple in operation, low in cost, free of potential drug residue risks, high in safety and the like.
Description
Technical field
The present invention relates to aquaculture field, relate to particularly a kind of biological method of removing violent water flea in Stichopus japonicus nursery pond.
Background technology
In China, stichopus japonicus is traditional health-care tonic product always, and the market demand constantly expands, and has greatly promoted the development of Apostichopus japonicus Aquaculture.Meanwhile, the demand of juvenile stichopus constantly increases, and violent water flea is the main harmful animal between stichopus japonicus nursery stage.Violent water flea is microcrustacean, and body length is less than 3mm, and its amount reproduction can produce very large harm to young ginseng; Be mainly manifested in that the breeding of violent water flea is very fast, energy is stronger, not only, with young ginseng contention bait and living space, also can peck the body surface of the young ginseng of wound, cause secondary infection and ulcer, finally cause young ginseng fragmentation, osteocomma to come off and the death of disintegrating, when serious, can cause entire PLA's destruction.Therefore numerous scientific research personnel and practitioner seek several different methods and kill the violent water flea in stichopus japonicus nursery pond, as used chlorophos, depulization spirit, Chinese herbal medicine etc. to kill violent water flea; But said method not only exists the hidden danger of medicament residue, and need to change water after using medicine, increased cost.Therefore the method for being badly in need of a kind of new drug residue free of invention, effect duration length is removed the violent water flea in stichopus japonicus nursery pond, survival rate and the benefit of to improve stichopus japonicus, growing seedlings.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of biological method of removing violent water flea in Stichopus japonicus nursery pond, to solve the problem that juvenile stichopus survival rate is low, growth is poor that in current stichopus japonicus seedling raising process, violent water flea causes.
The present invention is achieved through the following technical solutions:
Remove a biological method for violent water flea in Stichopus japonicus nursery pond, put into the healthy prawn shrimp seedling of the long 0.4cm～0.6cm of body in Stichopus japonicus nursery pond, putting seedling quantity is every cubic metre of water body 11～50 tails.
Described prawn shrimp seedling is any in Chinese prawn shrimp seedling, white leg Shrimp seedling and japonicus shrimp seedling.
The present invention's beneficial effect compared with prior art:
The present invention utilizes the long 0.4cm～2cm of body prawn shrimp seedling to have the biological nature of the violent water flea that ingests, do not ingest simultaneously and damage the feature of juvenile stichopus, adopt biological method to remove the violent water flea in stichopus japonicus seedling water, compare with existing pharmaceutical methods, there is easy to use, simple to operate, the advantage such as cost is low, drug residue free hidden danger, safety height.
Embodiment
Below by embodiment, technical scheme of the present invention is further explained, protection scope of the present invention is not subject to the restriction of embodiment.
Embodiment 1
On June 2nd, 2012, in 5 the 100 cubic metres water body stichopus japonicus nursery ponds in No. two workshops of factory of growing seedlings of battledore island, Dalian sea cucumber Development Co., Ltd, 500,000 of young ginsengs are cultivated in every pond, the long 0.1cm of body left and right, and it is 0.2～0.5/cm that young Shenfu density
2, 20～22 ℃ of water temperatures, salinity 30, pH8.0, dissolved oxygen 5mg/l, illumination 400lx, continuous charge in young ginseng cultivating process, every day, bait throwing in was 2-3 time.
Finding June 10 all has a small amount of violent water flea in above-mentioned 5 nursery ponds, and June 11 put in No. 3, No. 4 ponds the healthy white leg Shrimp seedling that body is grown 0.5～0.6cm, and putting into quantity is every cubic metre of water body 25 tail shrimp seedlings; In No. 5, No. 6, No. 7 ponds, use traditional chlorophos to kill violent water flea method, consumption is 2-3mg/L simultaneously.June 13 was observed above-mentioned 5 young ginseng nursery ponds, did not all find violent water flea, illustrated that use prawn shrimp seedling and chlorophos are respond well to removing violent water flea.After this cultivate according to a conventional method young ginseng.More than to September 1, Stichopus japonicus grew to 0.9cm, violent water flea is not found in No. 3, No. 4 ponds of using the inventive method to remove violent water flea again, simultaneously due to shrimp seedling can not injure and ingest young ginseng so Stichopus japonicus well-grown.And No. 5, No. 6, No. 7 ponds of using chlorophos respectively in July 12, July 25, August 3 owing to finding that violent water flea reuses chlorophos.Added up the output of seedling in each pond on September 1, concrete culture efficiency is in Table 1.
Table 1 the inventive method is removed the culture efficiency contrast of violent water flea in water body with using chlorophos
| Pond number | 3 | 4 | 5 | 6 | 7 |
| Violent water flea sweep-out method | The present invention | The present invention | Chlorophos | Chlorophos | Chlorophos |
| Access times | 1 time | 1 time | 4 times | 4 times | 4 times |
| Output of seedling | 24.8Kg | 26.1Kg | 23.7Kg | 25.2Kg | 24.5Kg |
Therefore use method of the present invention to control Stichopus japonicus than traditional medicine and cultivate the violent water flea in water body, not only easy to use, effect is remarkable, and has avoided medicament residue hidden danger, has improved Product Safety.
Claims (2)
1. remove a biological method for violent water flea in Stichopus japonicus nursery pond, put into the healthy prawn shrimp seedling of the long 0.4cm～0.6cm of body in Stichopus japonicus nursery pond, putting seedling quantity is every cubic metre of water body 11～50 tails.
2. a kind of biological method of removing in Stichopus japonicus nursery pond violent water flea according to claim 1, is characterized in that described prawn shrimp seedling is any in Chinese prawn shrimp seedling, white leg Shrimp seedling and japonicus shrimp seedling.
