摘要： PURPOSE:To enable even transportation of not only live fishes and shellfishes but also fresh fishes or frozen fishes and shellfishes by providing a fish and shellfish tank divided into >=2 cells with >=1 cooling panels having flow ports of water. CONSTITUTION:A tank 1 divided with at least one cooling panel 6 having plural holes 7 (for flowing water) is provided. A means 3 for circulating water in the tank 1 through a water passage 2 on the outside of the tank 1 and the plural holes 7 may be provided. At least one (e.g. 5b) of cells 5 in the tank 1 divided with the cooling panel 6 is preferably used as a fish and shellfish housing cell and a filter medium may be housed in at least one cell (e.g. 5a or 5c) of the aforementioned cells 5. A type in which, e.g. a cooling pipe 8, is arranged in the interior thereof and cooling is carried out by flowing a desired refrigerant through the pipe 8 can be adopted as the cooling panel 6. Water is contained in the fish and shellfish tank 1 and live fishes and shellfishes are transported while forcibly circulating the water with a circulating pump 3 arranged in the circulation water passage 2. Furthermore, fresh fishes or frozen fishes and shellfishes are transported in a state of water drained from the interior of the fish and shellfish tank 1.

摘要： PURPOSE:To efficiently feed oxygen into a living fish tank by cleaning the circulating water in said tank with filters and a deaerating tank followed by chilling the water through a chiller and then injecting oxygen or air from a gas distributor into said circulating water. CONSTITUTION:The water in a living fish tank 1 is circulated with a circulating pump 5, and the circulating water is first introduced into filters 2 to remove solid floating matter, microorganisms, ammonia, odor, etc. The resultant circulating water is introduced into a deaerating tank 4 where the residual carbon dioxide dissolved in said water is removed. The resultant circulating water is brought, under pressure, to a chiller 6 where the water is chilled through a chilling coil 21 installed in the chiller 6, and at the same time, oxygen or oxygen-contg. gas is injected from a gas distributor 22 installed in said chiller 6 followed by circulating the resultant water into the living fish tank 1. Thereby, the tank 1 will be always filled with clean water with oxygen dissolved sufficiently and uniformly, thus living fishes being never weakened.

摘要： PURPOSE:To obtain a vacuum-packed raw oyster with shells having a hole previously bored through a shell in which a consumer can appreciate a fresh raw oyster with shells by inserting a cutting tool into the hole of the shell, cutting an adductor muscle to readily peel the shell. CONSTITUTION:A hole for cutting an adductor muscle is bored through the under surface of the deeper shell among two shells of an oyster with two shells and, in a view in which a ligament is arranged at the left side, at the joint part of the two shells at an approximately site wherein an axis intersecting closely the center passing through the ligament in longer direction is brough into contact with the shell at the lower part, the raw oyster with shells is put in a packaging bag and sealed under reduced pressure to give a vacuum-packed raw oyster with shells.

摘要： PURPOSE:To make it possible to efficiently feed oxygen to water in culture pond and carry out reduction of equipment and maintenance by feeding water in culture pond to a diffusion pump arranged in a small-sized aeration tank under pressure and blending the above-mentioned water with air. CONSTITUTION:Water in a culture pond 1 is mixed with air by passing water in the culture pond 1 through an air introduction chamber 20 of diffusion pump 19 arranged in a deaeration tank 6 at high speed and the gas-liquid mixed flow is jetted into water in culture pond 1 staying in the deaeration tank to supply oxygen to water in culture pond. Thereby oxygen is efficiently adsorbed in water in culture pond and installation numbers are reduced compared with a conventional waterwheel or sprinkler, because sufficient gas liquid contact of water with air is carried out under stirring conditions by water flow jetted into a tank.

摘要： PURPOSE:To efficiently feed oxygen to a live fish tank by cleaning circulating water by a filter and a deaerating tank, dripping the cleaned water from a sprinkler as very small waterdrops on the active fish tank, bringing the waterdrops into contact with air and absorbing oxygen in the waterdrops during falling. CONSTITUTION:Water in a live fish tank 1 is circulated by a pump 5, solid floating substances are removed by a filter 2b and ammonia and smell are eliminated by a filter 2c. Then the circulating water is introduced to a deaerating tank 4 to degas a dissolved carbon dioxide gas. Then the circulating water is sent to a sprinkler 6 set above the live fish tank 1 under pressure, the circulating water from the sprinkler 6 is sprayed and dripped as very small waterdrops, brought into contact with air and oxygen is sufficiently absorbed in the circulating water during falling and sent to the live fish tank 1. Consequently, since the fish live tank 1 is filled with cleaned water having sufficiently and uniformly dissolved water, live fishes are not weakened.

摘要： PURPOSE:To enable the easy shelling of a raw oyster with shell even by an unexperienced person by inserting a cutting tool through a specific position and cutting the adductor of the oyster. CONSTITUTION:A raw oyster with shell is placed by directing the deeper shell between two shells downward and the ligament to the left side. The part connecting two shells is ground at a part where the axial lines perpendicularly crossing nearly at the center of the width in the longitudinal direction passing through the ligament of the shallower shell are brought into contact with the shell at the lower part. A cutting tool 10 is inserted into the hole formed by the above operation to cut the adductor 3. The length L3 of the cut part is usually 2-3cm and the width H3 of the cut part is narrower the better provided that the cut part keeps the strength to enable the cutting of the adductor.
