Description
Technical field
The invention belongs to aquatic product transportation field, relate to particularly a kind of golden cuttlefish adult long-distance transport method.
Background technology
Under field conditions (factors), when facing a danger, ink-jet is cephalopodous a kind of escape behavior, near the seawater of the prepared Chinese ink of ejection can making becomes black, thereby hidden own, and by the current escape of quick ejection, in addition prepared Chinese ink also contains toxin, and harmful animal is also had to certain attacking role.In breeding process, find equally, during fight between parent purchase, fall pond operation and individuality siphonopods also as easy as rolling off a log generation ink-jet behavior, especially long-distance transport front pack, weigh and transportation in ink-jet phenomenon even more serious.The ink-jet behavior of siphonopods in transportation not only damages physique, also easily ruins water quality, causes transportation survival rate lower, limited to a certain extent the development of its industry.
Aspect siphonopods research, abroad focus mostly in basic research such as Resources of Cephalopods investigation and biological propertyes, Chinese aspect siphonopods aquaculture in rank first.At present, the principal item of domestic siphonopods exploitation cultivation is golden cuttlefish, Sepiella maindroni, octopus (true octopus, short octopus and long octopus) etc.In these kinds, octopus class is due to without inner casing, health softness, and ink ejection amount is little, adopts low-temperature transport survival rate very high, does not have transportation technology bottleneck.And golden cuttlefish and Sepiella maindroni have hard inner casing, not low temperature resistant, and irritant reaction sensitivity to external world, as easy as rolling off a log ink-jet and collision in transportation, finally because water quality is ruined or somatic damage dead.Both compare, and golden cuttlefish individuality is larger, is 4~5 times of Sepiella maindroni, therefore ink ejection amount is larger, and golden cuttlefish has tailpin, after collision, health tail muscles also more easily damages and causes tailpin and inner casing to expose, and therefore golden cuttlefish long-distance transport difficulty is larger.At present golden cuttlefish is mainly take short-distance transport as main, and method is mainly used for reference fish plastic sack oxygenation transportation, but the method golden cuttlefish the ink-jet rate of 4~5 hours up to more than 60%, transportation survival rate is extremely low, is only 40%.Therefore golden cuttlefish long-distance transport technology has limited the popularization cultivation of golden cuttlefish to a certain extent, is the bottleneck of its Industry Promotion.
Anaesthetic can make aquatic livestock peace and quiet, and then reduces the stress reaction while adopting the operation such as ovum, semen collection, blood sampling, makes to operate smooth.In addition,, in transportation, anaesthetic can reduce metabolism, the injury of minimizing to animal bodies of aquatic livestock, and then improves transportation survival rate.Therefore, anaesthetic obtains certain application in aquaculture.Fish is more with anaesthetic at present, comprise nearly 30 kinds of MS-222, sulfuric acid quinaldine, eugenol, 2-Phenoxyethanol etc., wherein MS-222(chemistry alkylsulfonate coordination benzocaine by name) there is aquatic livestock and enter the advantages such as fast and recovery time of fiber crops is short, to be that our times various countries are widely used in the safest in aquatic livestock, the most reliably, the most effective anaesthetic, and through FDA(food and drug administration) approval, for aquatic livestock anesthesia transportation.
Aspect siphonopods transportation, Japanology squid live body long-distance transport method, mainly contain three kinds: 1) remove ink sac; 2) use ethene and add the seawater of special oxide, and water temperature is controlled to 5 ℃ of left and right; 3) with the seawater " hypothermic anesthesia " of-2 ℃.Although adopt these methods to transport for long-distance, the squid survival after long-distance transport is shorter, is only 12h~1 week, and therefore these methods are unwell to the transportation of siphonopods parent.At home, the principle of the employing anesthesia such as Wu Changwen has been invented a kind of siphonopods parent live transport pre-treating method and special agent (application number: 201010607873.0), open up Liao Yitiaoxin road for siphonopods transports.But because siphonopods kind is more, there is interspecific difference in different cultivars, the selection of anesthesia kind, concentration, narcosis etc. are also not the same, and the zeolite granular of selecting in this invention in addition only absorbs ammonia nitrogen and prepared Chinese ink, but is dissolved into the toxin in water after cannot removing ink-jet.
That golden cuttlefish has is individual large, ink ejection amount is large, oxygen demand is large, stress reaction is fierce and inner casing tool tailpin very easily causes the features such as somatic damage, therefore control not ink-jet in golden cuttlefish operation and transportation, improve transportation water-soluble oxygen, keeping transportation peace and quiet is the keys that improve its long-distance transport survival rate.Have no at present the report of golden cuttlefish adult long-distance transport method both at home and abroad.
Summary of the invention
