Abstract

The invention belongs to the field of breeding of aquatic livestock, and particularly relates to a device and method for cleaning and sterilizing nauplii of shrimps by slow flowing water. The device comprises a temporary breeding barrel and a cylindrical net case, wherein the cylindrical net case is placed in the temporary breeding barrel and is higher than the upper edge of the top of the temporary breeding barrel by 20 cm; the cylindrical net case comprises a supporting framework, a cylindrical string bag and binding ropes; the supporting framework is formed by welding stainless steel tubes;the binding ropes are separately arranged at the upper edge and the bottom of the cylindrical string bag; and the cylindrical string bag is fixed to the supporting framework by the binding rope, so that the whole cylindrical string bag and the supporting framework are attached closely. By the method for cleaning and sterilizing by the slow flowing water, the damage rate and the dirty rate of thenauplii can be reduced by 20%-40%, the vibrio carrying amount of the nauplii is reduced by 50%-80%, the device and method are quite suitable for actual production of the nauplii, thus, the quality ofthe nauplii is optimized, and the survival rate of the nauplii is increased effectively.

Description

technical field [0001] The invention belongs to the field of aquatic animal breeding, in particular to a device and method for cleaning and disinfecting shrimp nauplius with micro-flow water. Background technique [0002] Nauplius refers to the newly hatched larvae of certain crustaceans (such as copepods, cirripedes, krill, and decapod cladobranchs, etc.). Shrimp nauplii begin to appear at a higher developmental stage. The body is not yet divided into cephalothorax and abdomen, and it is flat and oval. There is a nauplius eye in front of the midline, and there is a mouth and alimentary canal behind it (The anus has not yet been opened), and there are 3 pairs of appendages on the left and right, including the first antennae, the second antennae and the mandible. The appendages are composed of several joints and have swimming bristles. [0003] Nauplius is the most basic link in the production process of shrimp seedlings. The quality of larvae and whether they carry infectio...
