Abstract

The invention discloses a lamplight trapping device and method for young marsupenaeus japonicus. The lamplight trapping device comprises a fixing device, a lamplight device and a capturing device, theinterior and the outer side of the top end of the capturing device are provided with the lamplight device and the fixing device respectively, and the lamplight device is fixedly connected with the fixing device through a trapping lamp support; and a connecting hole and a shrimp outlet are respectively formed in the interior and the bottom end of the capturing device through netting brackets, anda shrimp inlet is woven in the side edge of the capturing device through a netting. The lamplight trapping device is easy to operate, low in cost, small in marsupenaeus japonicus damage, high in capture efficiency and survival rate, suitable for field collection and pond collection of the young marsupenaeus japonicus, capable of carrying out scientific research on the marsupenaeus japonicus, highin practical value and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of prawn fishing, in particular to a lighting trapping device and method for juvenile Penaeus japonicus. Background technique [0002] Marsupenaeus japonicus, also known as Kuruma prawn, also known as flower shrimp, is native to Japan, China, the Philippines, Australia and other countries, and is one of the important marine cultured species in my country. Because of its delicious meat, strong stress resistance, and suitable for long-distance dry dew transportation, it is deeply loved by shrimp farmers and consumers. In 2018 alone, the aquaculture output of Penaeus japonicus reached 55,228 tons, bringing huge economic benefits to coastal farmers. Therefore, Penaeus japonicus has great research value. However, Penaeus japonicus is not easy to catch in the juvenile stage, which brings great difficulties to scientific research. Because it has extremely strong phototaxis habit in juvenile stage, therefore, it ...
