A kind of Porcelain Jar cultivates the cultural method of flying horse wise man water flea
Technical field the invention belongs to aquaculture field, particularly relates to a kind of method that Porcelain Jar cultivates flying horse wise man water flea.
Background technology
Flying horse wise man water flea Calanus fimarchicus is a kind of small ocean copepods zooplankton, be subordinate to Arthropoda Arthropoda, Crustachia Crustacea, calanoida Calanus, wise man water flea section Calanidae, wise Daphnia Calanus, body is long is less than 3mm, battalion swims and parasitic life, is distributed in ocean, warm temperate zone.Being widely distributed in Bohai and Yellow Seas and the East Sea, is the important bait of economic fish such as Pacific herring, chub mackerel and the young, baleen whales, European North Sea Pacific herring.Flying horse wise man is directly fished in Norway coastal waters, and water flea does the mankind, livestock and poultry foodstuff has history decades, has very high nutritive value.In addition, flying horse wise man water flea and ocean current closely related, can be used as ocean current, water body indicator organism; Also can be used as water pollution indicator organism also as the mark finding fishing ground.In filtered water, the suspended particulate such as diatom, bacterium, organic debris is food.
Current copepoda is cultivated outdoor extensive style and indoor intensiveization two kinds.The outdoor extensive cultivation place of large area should be selected in bay, river mouth and nearshore waters.Outside scenery output height often depends on bait micro-algae supply situation, and outdoor earth pond is cultivated copepoda and achieved good result in recent years, but remain unstable in output, continue that supply time is short, the problem such as susceptible viral and germ contamination.From the nineties in last century, people attempt carrying out the intensive cultivation of copepoda.Wise man's water flea class and violent some kind of water flea class, comparatively strong and as the ideal object of intensive cultivation to environmental suitability, for wise water flea kind many genus offshore or the river mouth kind of intensive cultivation, as Acartia genus, chest thorn Daphnia, very wide Daphnia and wide Daphnia, these kind individualities are little, breeding is fast, wide temperature, wide salt, are applicable to laboratory cultures.Relative to wise water flea class, the violent water flea class battalion end dwell life, can High Density Cultivation, the history of life is short, bait is extensive etc., and feature makes it be suitable for intensive large-scale culture.Outdoor earth pond cultivation fee is low, but yields poorly, by limiting and susceptible viral and germ contamination in season and water temperature; Intensive cultivation output is high, little by effect of natural conditions, but cost is high, and for winter and early nursery in spring, the intensive cultivation of copepoda is more applicable.
About the cultivation of flying horse wise man water flea, past Zhao Wen etc. has invented a kind of large-scale cultivation method for marine floating harpacticoida (application number CN200910248644).This invention can improve cultivation efficiency, and reduce production cost, the nursery for marine products economic animal provides reliable food supply.Described violent water flea large-scale cultivation method carries out as follows: violent water flea cultivation salinity water is 20ppt, temperature 24 DEG C, water body dissolved oxygen > 5mg/l, pH=7-8, bait is at least one in lsochrysis zhanjiangensis, Dunaliella salina and Chaetoceros muelleri, and the initial density of violent water flea cultivation is 50-100ind./l breeding water body, and the quantity delivered of bait is 5 ~ 10l/d, upgrade 300l breeding water every day, cultivation to violent water flea density is at least 1500ind./ml; Gather in the crops the violent water flea in 500l water body every day and fill into fresh breeding water, bait consumption is 10-15l/d, continuous culture 30-50d.The method easily pollutes, and power consumption is higher and operating technology requires high, and general workman is difficult to grasp, and practicality is not strong.
In order to overcome the deficiency of current technology, the invention discloses a kind of method that Porcelain Jar cultivates flying horse wise man water flea, compared with conventional art, Heterosis of the present invention exists: 1) adopt Porcelain Jar, sturdy and durable, not easily break up, scrub conveniently, reuse, easy to operate, economize on the use of funds; 2) throw something and feed bacterium and little ring algae, Skeletonema Costatum, rhombus hailian seaweed, flying horse wise man water flea growth and breeding is fast, and physique is healthy and strong, and output is high, is not subject to seasonal restrictions; 3) inflate and use magnetized drinking water with conical flask series connection when cultivating micro-algae, algal grown is fast, and output is high, and the gas be filled with obtains 3 times and utilizes, and has saved resource and energy.
