Abstract: Purpleback flying squid is one of the most potential fishery resources in the South China Sea. The squid is mainly
caught by light-attracting falling-net fishing vessels. It is of great significance to develop the light-attracting falling-net fishing
fishery of purpleback flying squid. Combined with the research status at home and abroad, the current situation and existing
problems of light attract falling-net fishing technology in the South China Sea were summarized from three aspects: fishery
situation prediction, light net fishing technology and fish collecting lamp. ① In terms of fishing ground forecasting, the basic
research on light-attracting falling-net fishery is not comprehensive, and there is a lack of fishery data. The prediction model
parameters are single, and the accuracy rate of predicting high-yield fishery is low. ② In terms of light-attracting falling-net
fishing technology, the proportion of juvenile fish in fishing is high, the selectivity of fishing is low and the performance of
fishing gear remain understudied. In the future, the falling-net and tuna longline fishing industry can be developed. ③ In terms
of fishing lamps, LED as the future development trend of fishing lamps, although it has the advantages of energy saving, low-
voltage start and spectral controllability, there are a series of problems to be solved at the technical and application levels. It is
concluded that there is a broad space for the development of purpleback flying squid fishery in the South China Sea, and relev-
ant research should be strengthened in the future.
