Abstract: Provided is an aquacultured crustacean having improved umami, uses thereof, and a method for producing the same. The crustacean does not burrow in sand, contain glycine and alanine, and has 2400 mg or more of free amino acids per 100 g of abdominal muscle. The content of glycine is 550 mg or more per 100 g of abdominal muscle, and the content of alanine is 140 mg or more per 100 g of abdominal muscle.

Abstract: A method of rearing an aquaculture shrimp includes keeping shrimps in a land-farming nursery, and feeding to the shrimps kept in the land-farming nursery a feed including astaxanthin in an amount of 50 ppm or greater.

Abstract: An aquacultured shrimp contains carotenoid and does not have a broken 2nd antenna.

Abstract: An aquaculture system including an aquaculture tank for holding aquaculture water for culturing an aquatic organism, a thermal insulation house that covers the aquaculture tank, an insulation positioned on at least part of a region surrounding the aquaculture tank, and a temperature adjuster that adjusts a temperature inside the thermal insulation house and/or a temperature of the aquaculture water in the aquaculture tank.

Abstract: Problems are posed by slip prevention particle injection devices by wheels of railway rolling stock. Namely, if the injected quantity of slippage-preventing particles is adjusted so as not to be excessive and to be a suitable quantity, it is not possible to obtain a predetermined injection pressure and it is not possible to inject the particles at the target location. The injector device of the present invention is constituted by providing an air through-flow duct 5 inside a particle retainer tank 1, and connecting an air supply duct 17 to this air through-flow duct 5. In the above mentioned tank 1, in addition to an air inflow duct 6 being provided in the vicinity of the inlet side of the air through-flow duct 5, an air discharge duct 18 is provided in the vicinity of the outlet side of the air through-flow duct 5. This air inflow duct 6 and air discharge duct 18 are connected to the air through-flow duct 5 and one end of these ducts 6 and 18 is open into the tank 1.
