Long-distance transportation method for adult sepioteuthis lessoniana

Abstract

The invention provides a long-distance transportation method for adult sepioteuthis lessoniana, and belongs to the field of aquatic product transportation. The method narcotizes adult sepioteuthis lessoniana, ties or clamps the transparent parts at the mouths of ink sacs with a ligation device and carries out low-temperature transportation. Through the adopting of high-concentration anesthesia operation and low-concentration anesthesia transportation, ink-jet phenomenon during transportation can be completely solved, operation damage can be effectively avoided, and oxygen consumption rate during transportation can be reduced.

Description

technical field [0001] The invention belongs to the field of aquatic product transportation, and in particular relates to a long-distance transportation method for adult squid. Background technique [0002] Under natural conditions, when encountering danger, inkjet is a kind of escape behavior of cephalopods. The ink sprayed can turn the nearby seawater into black, thereby hiding itself and escaping with the rapid jet of water. In addition, ink contains toxins, which also have a certain offensive effect on enemies. In the breeding process, it was found that cephalopods are also prone to inkjet behavior during broodstock acquisition, tank dumping operations, and individual fights, especially during long-distance transportation before bagging, weighing and transportation. serious. The inkjet behavior of cephalopods during transportation not only damages the physique, but also easily deteriorates the water quality. Once inkjet is sprayed during transportation, the mortality r...

Wu Changwen et al. invented a pretreatment method and special reagents for the transportation of cephalopod living bodies by using the principle of anesthesia (application number: 201010607873.0), which opened up a new way for the transportation of cephalopods, but there are differences between different species, such as some The varieties have well-developed ink sacs and a large amount of inkjet, and the selection of anesthesia, concentration, and anesthesia state are not consistent. In addition, the zeolite particles selected in this invention can only absorb ammonia nitrogen and ink, but cannot remove the ink dissolved in water after inkjet. toxin

Japan has studied the live long-distance transportation method of removing the ink sac of calamari. Although this method can be used for long-distance transportation, the operation is cumbersome, the technical requirements are high, and the damage to squid is relatively large. The survival time of calamari after long-distance transportation is relatively short , in addition, the transported broodstock can no longer reproduce, so it is not suitable for the transportation of cephalopod broodstock

Therefore at present cephalopods, especially squids and guniformes species, also lack a long-distance transport method for cephalopods that is simple to operate, has little damage to the body, and has a high survival rate.
