  • the costs of feed used in an aquaculture industry and epsecially in a shrimp farming industry take up a very large proportion, aproximately 40% of the total costs. Improvements of a food conversion rate (FCR) to a finished product weight are especially important.

  • the redundant feeds not only are wasteful but affect the water quality of the farming pond, cause the diseases for liverstock.
  • a plural of known apparatuses of feeding shrimp are produced.
  • a problem of the apparatuses of feeding shrimp is that the feed amount is unevenly distributed on the surface of the farming, where there is a redundancy, where there is a shortage. This results in that the shrimps of the same class unevenly growth, making it difficult to shrimp harvest.
  • the redundant feeds rapidly cause the water pollution the farming pond.
  • the apparatuses of feeding in aquaculture in particular an apparatus of spreading the feed for shrimp is conventionally provided with two or three feed spreading tubes which are attached perpendicular to the axis of a rotating unit.
  • the feeds are dropped into the rotating unit va are spread by the centrifugal forces via said tubes when the rotating unit is rotated by electric motor which is operationally connected the rotating unit. Since the feed spreading tubes are the same in structure, the feeds to be spread from the apparatus are concentrated in a fixed area. The other area, which is father or closer than such an area, the feeds generally do not exist. This leads to the fact that in one place there are too much shrimp feeds to eat, while in other place there are not any feeds.

  • the feeds will be spread around the apparatus of feeding shrimp 100 in a certain radial range.
  • the feeds will be rapidly, fully and uniformly spread.
  • the shrimps will easily eat it all without concentrating in a small feed region. Therefore, the apparatus can substantially improve the FCR.

Abstract

L'invention concerne d'une manière générale un appareil d'alimentation utilisé en aquaculture. En particulier, la présente invention concerne l'appareil d'alimentation pour crevettes et l'épandeur d'aliments de l'appareil. L'épandeur d'aliments comprend les tubes d'épandage d'aliments qui sont structurés pour adopter les différentes longueurs et les différents angles formés par l'axe des tubes d'épandage d'aliments par rapport à un plan perpendiculaire à l'axe de l'unité rotative, ainsi, l'appareil peut épandre plus uniformément les aliments dans la radiale d'épandage d'aliments.
