Description

  The present invention relates to a method for keeping edible squid (especially large squid, squid, etc.) alive in a water tank for a required period, and to store or transport the squid, and a tool therefor.

  There is a great demand for fresh squid dishes in ginger restaurants, the food service industry and general households. Therefore, the squid must be transported as lively as possible, stored in a water tank such as a restaurant, and used for the customers' meals.

  Squids landed live, when caught on the net, when they felt life threatened, when many squids were placed in a small aquarium, and when stress increased, or in contact with other squids and fish There is a habit of self-defense by discharging black ink from the ink bag in the internal organs when placed in an uneasy state. The ejected ink not only attacks the enemy, but also adheres to the squid's own water-breathing error, impedes its breathing activity, and weakens its vitality. In addition, it adheres to other fish's gills in the same tank, hindering respiratory activity and adversely affecting its vitality. This has been a major obstacle to transporting squid in the ship and onshore tanks, or to use it for cooking in the restaurant's tank. In particular, it was a fatal problem for large squids and large squids.

  The invention according to claim 1 of the present invention is a method for preserving live squid that is used in an aquarium after the ink bag of live squid is cut and discharged.

  The invention according to claim 2 of the present invention is a method for transporting live squid by cutting a live squid ink bag, discharging the black ink, and then transporting it in a water tank.

  According to claim 3 of the present invention, in the method for transporting and storing live squid according to claims 1 and 2, a plurality of compartments are provided so that water can flow in the aquarium, and the compartment is separate from the squid. It is a method of transporting and storing live squid that is stored and transported in the same tank.

  According to Claim 4 of the present invention, in Claims 1, 2 and 3, a spacer is inserted between the outer mantle and the funnel on the ventral side of the live squid to facilitate the internal observation of the live squid and the insertion of the blade. This is a method for transporting and storing live squid by cutting the live squid ink bags.

  The invention according to claim 5 of the present invention is a tool for cutting a live squid ink bag according to claims 1, 2, 3 and 4, wherein a rod-like body having a blade at its tip is placed in a protective cylinder. The blade can be protruded from the tip of the protective cylinder by being housed and pushing the rear part of the rod-shaped body.

  The invention according to claim 6 of the present invention is that according to claim 5, comprising at least a fiberscope of the fiberscope and the light.

  The invention according to claim 7 of the present invention is a tool for cutting a live squid ink bag according to claims 1, 2, 3 and 4, wherein the two pieces of scabbage are pivotally attached to two blades. The length from the pivot axis to the tip of the blade is different.

  According to an eighth aspect of the present invention, in the seventh aspect, at least one of a protective cap, a light, and a mirror is provided at the tip of the longer one of the two blades.

  The invention according to claim 9 of the present invention is a tool for cutting the live squid ink bag of claim 4, which is inserted between the mantle and the funnel on the ventral side of the live squid, This is a cylindrical spacer or a cylindrical spacer cut in the axial direction to facilitate internal observation and blade insertion.

  In the method of the invention according to claim 1 of the present invention, most of the black ink can be discharged by cutting in advance the squid ink bag to be put in the water tank. Further, since the torn black bag has no contraction force, it is not possible to discharge even a little remaining ink. Therefore, the squid ink does not adhere to the squid's underwater breathing error and obstruct the respiratory activity. Ink bags are not directly related to the life support of squid, and will not kill their vitality if they are not damaged when they are torn. In this way, the squid in the aquarium can continue to live for a long time. In addition, a relatively small aquarium can be used to store many squids. Therefore, it is possible to always provide fresh squid dishes to customers at restaurants.

  In the method of the invention according to claim 2 of the present invention, the squid ink bag is cut in advance, the ink is discharged, and then transported in a water tank. Therefore, as described in the column 0013, the squid can live for a long time and can be transported far away. In addition, many squids can be placed in a relatively small aquarium and transported at low cost.

  In the method of the invention according to claim 3 of the present invention, a plurality of compartments through which water can flow is provided in the aquarium, fish is put in a compartment separate from the lively squid, and stored and transported in the same aquarium as the squid. . In this case, the squid ink does not interfere with not only the squid but also the fish for underwater breathing and does not interfere with the respiratory activity. Therefore, it is possible to make use of a large number of squid and fish in the same aquarium simply by providing a simple partition such as a net. Therefore, it is possible to always provide fresh squid and fish dishes to the customers' meals. In addition, a large number of squids and fishes can be transported far away at low cost.

  In the method of the invention according to claim 4 of the present invention, a spacer is inserted between the mantle on the ventral side of the live squid and the funnel, and the live bag of the live squid is cut. By inserting the spacer, it is easy to observe the inside of the live squid and insert the blade, and it is possible to treat the ink bag without damaging the internal organs of the squid other than the ink bag and without damaging the vitality of the squid. .

  In the tool for cutting a live squid ink bag according to claim 5 of the present invention, the blade stored in the protective cylinder is inserted into the body of the squid, and after reaching the black bag, the tool is removed from the protective cylinder. Since the blade is cut and the ink bag is torn, and then stored again in the protective cylinder and pulled out from the body of the squid, the internal organs of the squid other than the ink bag are not damaged. Therefore, it is possible to cut the ink bag without weakening the vitality of the squid.

  According to a sixth aspect of the present invention, in the tool for cutting a live squid ink bag, the blade with a protective cylinder according to the fifth aspect is provided with at least a fiberscope among a fiberscope and a light. Therefore, it becomes possible to observe the inside of the squid more accurately, and it is possible to safely cut the squid ink bag.

  The tool for cutting a live squid ink bag according to claim 7 of the present invention is a stigma with different lengths of two blades, and is suitable for a treatment for cutting a relatively small squid ink bag.

  A tool for cutting a live squid ink bag according to claim 8 of the present invention is provided with a protective cap, a light, Since at least one of the mirrors is provided, the squid ink bag can be cut more accurately and safely.

  A tool for cutting a live squid ink bag according to claim 9 of the present invention is inserted between an outer mantle and a funnel on the ventral side of the live squid to facilitate observation of the inside of the live squid and insertion of a blade. This is a cylindrical spacer for cutting or a cylindrical spacer cut in the axial direction. It is possible to insert the blade after observing the inside of the squid through the gap inside and outside the inserted spacer and checking the black bag, so that the vitality of the squid can be restored without damaging the internal organs of the squid other than the black bag. It is possible to treat the ink bag without damaging it.

  As an embodiment of the present invention, Example 1 relating to a method for storing and transporting live squid and Examples 2 to 6 relating to tools therefor will be described.

  FIG. 1 is an explanatory diagram showing a situation where a squid ink bag is being torn. 1 is a squid, 2 is a cutting tool, 3 is a black bag, 4 is an era (lung), and 5 is a liver.

  At the fish market and fishery cooperatives, etc., where the live squid is landed, the operator should cut into the body of the squid 1 while taking care not to damage the organs such as the gill 4 and the liver 5 that are necessary for maintaining the life of the squid Insert 2 and cut the ink bag 3. The cuttlefish that cut the ink bag 3 fully discharges the ink, soaks it up in seawater to wash out the ink, and puts it in a tank for transportation or a car. Ships and cars will quickly transport live squid to the consumption area, put it in a water tank such as a restaurant, and save it. In aquariums such as ships, cars, restaurants, etc., a simple partition may be provided with a net or the like, and other fish may be placed in a separate compartment from the freshly drawn squid and transported and stored in the same aquarium.

  Fig. 2 is a sectional side view of a blade with a protective cylinder for cutting a live squid ink bag. The blade is stored in the protective cylinder. Fig. 3 is a side sectional view of a blade with a protective cylinder. The state which protruded from the pipe | tube is shown. Reference numeral 11 denotes a cutter with a protective cylinder, and a rod-like body 13 having a cutter 12 attached to the tip thereof is slidably inserted into the protective cylinder 14. 15 is a spring, 16 is a handle, 17 is a stopper, and 18 is a key for preventing rotation.

  The operator inserts the blade 11 with the protective cylinder into the body of the squid 1 of FIG. At this time, the blade 12 of the blade 11 with the protective cylinder is housed in the protective cylinder 14 and does not damage the organs such as the error 4 and the liver 5 necessary for maintaining the life of the squid. Only after the tip of the protective cylinder 14 reaches the ink bag 3 of the squid 1 is the handle 16 pushed to cause the blade 12 to protrude from the tip of the protective cylinder 14 and to tear the ink bag 3. When the push of the handle 16 is stopped after the tearing, the blade 11 is again housed in the protective tube 14 by the force of the spring 15, and the blade 11 with the protective tube can be pulled out without damaging other organs.

  FIG. 4 is a view in which a fiberscope is attached to the blade with the protective cylinder of FIG. Reference numeral 19 denotes a fiberscope, 19a denotes an observation window, and 19b denotes an illumination window.

  The operator inserts the blade 11 with the protective cylinder into the body of the squid 1 and tears the ink bag 3 in the manner of the second embodiment. At this time, since the inside of the squid 1 is illuminated with the light from the illumination window 19b at the tip of the fiberscope 19 and observed with the observation window 19a, the work can be performed even if it is not so skilled. ， Can safely tear the black bag 3. If other illumination means such as a cap light is used, the illumination window 19b can be eliminated, and the fiberscope 19 can be made thinner and less expensive.

  FIG. 5 is a front view of itching as a tool for cutting the squid ink bag. 21 is a sag, 22 is a long blade, 23 is a short blade, 24 is a pivot, 25 is a guard, and 26a and 26b are handles.

  The operator inserts the itch 21 into the body of the squid 1 with the two blades 22 and 23 closed. At this time, since the guard 25 is attached to the tip of the long blade 22, it is possible to prevent an organ such as the error 4 from being damaged. When the guard 25 at the tip of the long blade 22 reaches the black bag 3, the blades 22 and 23 are opened and the black bag 3 is pierced by the tip of the short blade 23 while taking care not to damage other internal organs. Thereafter, the ink bag 3 is torn up with the two blades 22 and 23.

  FIG. 6 shows a state in which a protective cap and a mirror are attached to the tip of the blade having the longer sag in FIG. Reference numeral 27 denotes a protective cap, and 28 denotes a mirror. Further, a light may be attached to the tip of the longer blade.

  The operator inserts the itch 21 into the body of the squid 1 in the manner of the fourth embodiment, and tears the ink bag 3. At this time, the protective cap 27 prevents the organs such as the error 4 from being damaged more reliably. Further, since the work can be performed while observing with the mirror 28, the ink bag 3 can be torn more accurately and safely even if it is not so skilled. Furthermore, if a light is provided at the tip of the longer blade, safety is further enhanced.

  Finally, Example 6 will be described with reference to FIGS. FIG. 1 is an explanatory view showing a situation where a squid ink bag is being torn, in which 1 is a squid, 6 is a mantle, 8 is a shell, 9 is a head, and 10 is a funnel. 7 is a spacer, FIG. 7 is a detailed view of the spacer, (a) is a perspective view, and (b) is a plan view. The spacer 7 may be a short cylinder formed by cutting a transparent vinyl tube and may have an axial cut 7a.

  The worker places the shell 8 of the squid 1 on the cutting board. When the live squid 1 moves the mantle 6 to breathe, a gap is formed between the mantle 6 and the head 9 or the funnel 10, so that a short cylindrical spacer 7 is quickly inserted into the gap. Then, since the inside of the squid 1 can be confirmed by observing the inside of the squid 1 from the gap between the inside and outside of the spacer 7, the blade 2 can be inserted accurately and safely, and the black bag 3 can be torn. The spacer 7 is an elastic vinyl tube. Even if the mantle 6 moves due to the breathing action of the live squid 1 and the gap between the head 9 or the funnel 10 expands and contracts, the spacer 7 deforms accordingly. It is possible to secure a field of view without giving a burden to the internal organs of the live squid 1 and without losing its vitality. Further, when the spacer 7 has an axial cut 7a, the spacer 7 is deformed corresponding to the movement of the mantle 6 more flexibly.
