To evaluate the feasibility of incorporating pelagic shrimp beam net gear and fishing methods targeting shiba shrimp, Metapenaeus joyneri, which migrate to surface waters at night, into the current fisheries management framework, scientific fishing experiments and commercial trial fishing operations were conducted in the coastal waters of Gochang-gun, Jeollabuk-do, Korea, from May to September 2025. Data obtained from the trial fishery were used to assess bycatch species composition, estimate stock abundance, and evaluate the suitability and economic performance of the proposed fishing gear and method. During the entire period of the scientific fishing experiments, a total of 27,047 individuals (220,564 g) representing 43 aquatic species were collected. Metapenaeus joyneri was the dominant species, accounting for 20,520 individuals (75.9%) of the total catch, followed by Nuchequula nuchalis 1,290 individuals (4.8%), Thryssa kammalensis 1,216 individuals (4.5%), Loliolus japonica 1,109 individuals (4.1%), Portunus trituberculatus 941 individuals (3.5%), and 38 other species 1,971 individuals (7.3%). The two vessels participating in the commercial trial fishery operated for a total of 22 fishing days in May and 24 fishing days in June. Total catches of Metapenaeus joyneri were 9,879 kg in May and 14,113 kg in June, corresponding to an average daily catch of 522 kg. The total auction value of the catch amounted to KRW 89.782 million. Stock assessment results indicated that the Metapenaeus joyneri stock in the coastal and offshore waters of Jeollabuk-do was in a stable condition, with no evidence of overfishing or stock depletion. The sustainable catch level of Metapenaeus joyneri was estimated at 342 tons. In addition, the profitability of the pelagic shrimp beam net fishery during the two-month trial period (May-June 2025) was estimated at 35.2%, indicating favorable economic performance. Therefore, if cooperative management of Metapenaeus joyneri resources can be established with the fishery of stow net on stakes sector, which is operating in the same fishing grounds focusing on the same primary target species, pelagic shrimp beam net gear and fishing methods targeting Metapenaeus joyneri could be incorporated into the existing fisheries management framework.
