The invention provides a combined LED
light source for reducing the
cannibalism rate of garrupa and application thereof. According to the method, the purpose of reducing the
cannibalism rate is achieved by combining the environment control technology and an accurate feeding manner by means of the environment control technology of creating a specific light environment, the illumination time and the illumination intensity in an industrialized garrupa
aquaculture workshop. The method is specially developed according to the avoidance tendency of main garrupa culture species such as saddletail groupers, pearl gentian groupers and
epinephelus septemfasciatus to the specific spectra,
light intensity and illumination period and the
appetite regulation and control rules of
epinephelus coioides juveniles. By means of the method, the
cannibalism of the garrupa can be effectively restricted, and economic losses caused by cannibalism during the intermediate culture period of industrialized garrupa seedlings are remarkably decreased. Moreover, operations is easy and convenient, the
automation degree is high, the health, safety,
energy conservation and environment protection are realized, and the method has high application and popularization value.
