<p>A method and a system for breeding fry in which greatly accelerated growth is realized while lowering variation of growth or fatality rate. An enclosed fry breeding water tank (1) provided with a function for isolating fry by means of meshes (1b, 1c) is supplied with breeding water of highly-dissolved-oxygen concentration at a flow rate low enough not to have any effect on the fry using an artificial lug (3). Since the breeding method of fry just hatched susceptible significantly to highly-dissolved-oxygen is switched from a conventional still water breeding method to a running water breeding method, variation of growth which could not be overcome by a conventional method can be suppressed, resulting in greatly accelerated reliable growth in safety.</p> |
