Abstract: (20 Views)

In the present study, the catch and fishing effort of Banana jellyfish (Catostylus perezi) were evaluated from two major fishing areas in the Persian Gulf (Iran), including Tis and Pozm, from March 2024 to March 2025. To estimate the monthly landed catch, sampling was conducted by collecting data at landing sites, using a combination of census method in space and sampling in time. A total of 503 Banana jellyfish were biometrically measured. The mean length (range) of C. perezi was recorded as 22 ± 6 cm (8–40 cm), and the mean weight (range) was obtained as 924 ± 342 g (180–1700 g). The results of fishing effort and catch indicated that Pozm station had the highest catch rate and fishing effort (in terms of boat-days) during the study period (P < 0.05). Overall, the estimated annual C. perezi catch was about 2200 tons (reaching approximately 3000 tons when including the head portion), with a total fishing effort of 3250 boat-days per year. The annual average catch per unit effort (CPUE) per boat was estimated at 456 ± 351 kg. The present study, based on catch rates and catch per unit effort (CPUE), can be considered for the conservation and sustainability of fishing, proper and principled management of exploitation, as well as for gaining a better understanding of the biological and population characteristics of this species.

Keywords: Catch, Catch per unit effort (CPUE), Banana jellyfish, Oman Sea.
