Abstract
The invention discloses a method for preventing and controlling copepods in a young sea cucumber breeding pond of tropical sea cucumbers. The method comprises the steps of after the young sea cucumbers are subjected to metamorphosis and attachment for two weeks and the length of the young sea cucumber is 0.5cm the young sea cucumber is 0.5cm long, putting amphiprioninae or chrysiptera cyaned or both into the breeding pond when copepods appear in the breeding pond, and culturing and managing the young sea cucumbers according to a conventional method. A large number of experiments show that the amphiprioninae and chrysiptera cyaned can coexist with the young tropical sea cucumbers without damaging the same and can control the copepods, so that the survival rate of the young sea cucumbers is high. Compared with the prior art, the method can reduce the use of medicines, is beneficial to protecting environments and improving the quality of sea cucumbers, and meanwhile, reduces workload in a young sea cucumber culturing period, and avoids mechanical losses of the young sea cucumbers in an operating process, thus being beneficial to the rapid and healthy growth of the young sea cucumbers.
Description
Technical field:
The present invention relates to the raising technology that tropical sea cucumber comprises Stichopus variegatus (Sempen) and rough stichopus japonicus, be specifically related to the preventing control method of copepoda biology in the young ginseng nursery pond of a kind of tropical sea cucumber.
Background technology:
Sea cucumber has higher nutritive value and medical value, is considered to traditional delicious food and invigorant in China, ranks one of " eight delicacies ".At present, for meeting growing to beche-de-mer products demand of people, tropical breading sea cucumber seedlings and aquaculture research are carried out just gradually in south.South marine site Copepods is many, and growth and breeding is fast, considers from marine food chain, and Planktonic Copepods is in the South Sea, the feed foundation of upper strata Main Commercial Fishes (as orchid circle Scad, mackerel and Sardinella aurita etc.).But in the tropical sea cucumber seedling raising process in south, especially, at young ginseng cultivation stage, copepoda very easily appears in nursery pond, if do not add control, copepoda meeting amount reproduction, produces harm to seedling.Copepoda is mainly manifested in three aspects to the harm of seedling: the one, and copepoda and young ginseng contention food organisms and living space; The 2nd, the injury of copepoda to young ginseng, can cause the bacterium of young ginseng skin to infect, fester, and can cause stichopus japonicus Large Scale Death if can not process in time; The 3rd, directly the young ginseng of predation, tears, preys on young ginseng as violent water flea can utilize flourishing mouthpart, after its amount reproduction, can cause falling sharply of young parameter amount.Therefore, in the young ginseng of prevention and control pond, the amount reproduction of copepoda is an important step that ensures that breading sea cucumber seedlings succeeds.Although copepoda can, by applying the trichlorphon of 1ppm～2ppm, be killed in time, copepoda very easily develops immunity to drugs; In addition, dead copepoda will be removed in time from cultivate pond, does not thoroughly easily cause bacterium amount reproduction as removed, in the operating process of removing dead copepoda, easily cause pond at the bottom of young ginseng mechanical damage and increased the workload of growing seedlings.
Summary of the invention:
The object of the invention is the demand in order to meet copepoda prevention and control in southern tropical sea cucumber seedling raising process, provide one both can effectively control copepoda in nursery pond, do not affected again the preventing control method of copepoda biology in the young ginseng nursery pond of tropical sea cucumber of young ginseng survival rate and growth.
In the young ginseng nursery pond of tropical sea cucumber of the present invention, the preventing control method of copepoda biology, is characterized in that, comprises the following steps:
Sea cucumber larval metamorphosis adhered to after 2 weeks, young ginseng length reaches 0.5 centimetre, when the copepoda biochron appears in nursery pond, can throw in clown fish (Amphiprioninae) or blue magic fish (Chrysiptera cyaned) or both throw, young ginseng still cultivates according to a conventional method and manages.
Preferably, described input clown fish or blue magic fish or both throwing, it is throw in clown fish or blue magic fish or both throw according to 2-6/cube of water body, throws in need not additionally throw something and feed clown fish and blue magic fish food according to density like this.
Preferably, the body of described clown fish and blue magic fish is long is 2-3cm.
Preferably, described sea cucumber kind is Stichopus variegatus (Sempen) or rough stichopus japonicus.
Preferably, described clown fish is son clown fish (Amphiprion ocellaris).
The present invention screens discovery by great many of experiments, and clown fish and blue magic fish can coexist with the young ginseng in the torrid zone, can not damage sea cucumber seedlings, and can control and scratch sufficient class biology, and young ginseng survival rate is high.Compared with prior art, the present invention can reduce drug use, is conducive to environmental protection and improves sea cucumber quality; Meanwhile, reduce young ginseng and cultivate workload therebetween, avoid the mechanical loss to young ginseng in operating process, thereby be conducive to the quick healthy growth of young ginseng.
Embodiment:
Following examples are to further illustrate of the present invention, rather than limitation of the present invention.
Embodiment 1:
Use son clown fish (Amphiprion ocellaris) and blue magic fish (Chrysiptera cyaned) prevention and control copepoda as example take rough Stichopus japonicus pond.
Contrast experiment: implementing place is Xisha Yongxing Island, time is in August, 2011, front and abnormal rear 1 week of rough Stichopus japonicus settlement and metamorphosis, once killed copepoda with chlorophos 2 times, but poor effect while re-using subsequently chlorophos processing for the 3rd time, part copepoda develops immunity to drugs, and can not thoroughly kill.
Implement experiment: after thoroughly the remaining chlorophos in nursery pond being removed.Sea cucumber larval metamorphosis adhered to after 2 weeks at that time, rough Stichopus japonicus body is about 0.5 centimetre, nursery pond breeding water body is 2.5 cubes, in nursery pond, there is a small amount of copepoda, now thrown in altogether the indigo plant evil spirit fish of long 2-3 centimetre of 12 urosome and the son clown fish of the long 2-3 of 3 urosomes centimetre, young ginseng still cultivates according to a conventional method and manages.Continue to mix 40 day time, in the time that rough Stichopus japonicus body reaches 2-3 centimetre, by till enhancement releasing, nurturing period copepoda quantity is effectively controlled, and young ginseng survival rate is high, and two kinds of sashimi (raw fish) are deposited well, the food of additionally do not throw something and feed son clown fish and blue magic fish.
Embodiment 2
Use son clown fish (Amphiprion ocellaris) and blue magic fish (Chrysiptera cyaned) prevention and control copepoda as example take the young ginseng of Stichopus variegatus (Sempen) pond.
Implementing place is East Sea Island, Zhanjiang, time is in October, 2011, Stichopus variegatus (Sempen) larval metamorphosis adhered to after 2 weeks at that time, young ginseng body is about 0.5 centimetre, nursery pond breeding water body is 10 cubes, when the copepoda biochron appears in nursery pond, throw in altogether the indigo plant evil spirit fish of long 2-3 centimetre of 15 urosome and the son clown fish of the long 3-4 of 5 urosomes centimetre, young ginseng still cultivates according to a conventional method and manages.Continue the 50 day time of mixed breed, be used to pond culture in the time that the young ginseng body of Stichopus variegatus (Sempen) reaches 3-4 centimetre till, nurturing period copepoda quantity is effectively controlled, and young ginseng survival rate is high, and two kinds of sashimi (raw fish) are deposited well, the food of additionally do not throw something and feed son clown fish and blue magic fish.
