Embodiment 1

[0026] On April 21, 2010, 50 octopus were transported from Lianjiang, Fujian, weighing 341-903g, 30 large-size shipping containers with a height of 34cm and 20 small-size shipping containers with a height of 25cm were selected. Soak the shipping container with bleaching powder one day in advance, with a dosage of 10 grams per cubic meter of water, and rinse with clean water three times the next day. Use a fishing net to remove the true octopus from the pool and immediately put it into the transport container, take another container and rotate it through the thread of the bottom 7 to the thread of the front opening 1 where the true octopus container has been placed. Three large-size shipping containers with a height of 34cm are stacked vertically, and four small-size shipping containers with a height of 25cm are stacked vertically. The front opening of the uppermost shipping container 1 is covered with a lid with a round hole, the size of the hole It is 1.0~1.5cm, and the hole s...

Embodiment 2

[0028] On May 25, 2010, 105 octopus were transported from Fujian Province using live fish carts. 45 large-size shipping containers with a height of 34cm and 60 small-size shipping containers with a height of 25cm were selected. Soak the transport device with bleach one day in advance, and rinse three times with clean water after scrubbing the next day. Use a fishing net to remove the true octopus from the pool and immediately put it into the transport container, take another transport device and rotate it through the bottom thread to the open end thread where the true octopus device has been placed. Three large-size shipping containers with a height of 34cm are stacked vertically together, and four small-size shipping containers with a height of 25cm are stacked vertically together. The front opening of the uppermost transport device is a lid with a round hole on the end cover. Combine the above The devices are tightly arranged in the transport vehicle, and the handle 2 of the ...

Embodiment 3

[0030] On October 16, 2009, 64 real octopuses were transported from Fujian in a live fish cart. Four glass fiber reinforced plastic devices with a diameter of 1.3m are used, and each device is placed with 16 true octopuses, which are fastened with nylon mesh. Each cube of water has an average distribution of 46 true octopus. The salinity of seawater is 30 to 34, that is, seawater that is directly extracted from the sea without adjusting the salinity is used. Pour water to the upper edge of the device. Add ice during transportation and keep the water temperature at 7-9℃. At the destination, there was a lot of ink in the water in the glass device. The vitality of the octopus was weak. Only 23 survived, with a survival rate of 35.94%. The skins of the surviving individuals were mostly damaged and some limbs were mutilated. It can be seen from Table 1 that the two transportations in 2010 used transportation devices, and the salinity and temperature of the transportation seawater...

Abstract

The invention relates to a method for catching and transporting Octopus vulgaris and a used device. The method is characterized by fishing the Octopus vulgaris by using a Tonna perdix net first and then independently placing the Octopus vulgaris in containers for transportation, wherein the temperature of sea water for the transportation is 10 to 16 DEG; the salinity is 2.5 to 2.8 percent; and 0.015 and 0.02g / ml MgCl2 is added for anesthesia. Each used transport container comprises a front-end opening and a bottom, and a front-end side wall and a rear-end side wall which are used for connecting an intermediate barrel, and is provided with through holes used for the exchange of water bodies. The transport containers avoid the mutual fighting among individuals, and reduce death rate and damage rate; the through holes on the containers effectively improve the exchange of waterflow; and thread structures at the front end and the bottom realize the assembly and disassembly of the device, so that the transport space is fully utilized and the transport density is greatly improved. The hypothermic anesthesia treatment is adopted during the transportation, so that the activity ability and the inkjet phenomenon of the Octopus vulgaris are effectively reduced. By the method, the long-term, long-distance and high-density transportation of the Octopus vulgaris can be realized, and conditions are provided for seedling breeding and large-scale multiplication and releasing resource repair.

Description

Technical field [0001] The invention relates to a method for collecting and transporting cephalopods in the field of aquaculture, in particular to a method for collecting and transporting true octopus and a device used for it. technical background [0002] The true octopus (Octopus vulgaris) belongs to the phylum Mollusca, Cephalopod, Octopod, Anchovy, and octopus, commonly known as octopus and octopus. It is a warm-water species. It is a warm water species in the Seto Inland Sea, Atlantic Ocean, Indian Ocean and Mediterranean Sea of ​​the world. They are widely distributed and are an important economically fished species in the cephalopods, and also an important economic octopus in the Fujian and Guangdong waters of China. True octopus has a short life cycle and a fast growth rate. It is an economic species with great breeding potential. [0003] The flesh is fresh and tender, and the protein and vitamin A content are rich. It has the functions of nourishing blood, nourishing qi,...
