Abstract Anguillid leptocephali of three Congridae species (Conger conger, Ariosoma balearicum and Gnathophis mistax) were caught as bycatch of pelagic trawls during acoustic surveys targeting small pelagic fish species in the southern Adriatic Sea, carried out under the framework of the Italian MEDIAS project (western side) and its extension in the ambit of the FAO AdriaMed project (eastern side). Results refer to the findings of Congridae leptocephali during surveys conducted in 2011, 2014, 2015 and 2016. A total of 25 specimens were caught and analysed (morphological features and pigmentation patterns). Leptocephali of Conger conger were found in the range of 8.4–13.1 cm total length (TL) (between 50 and 132 m depth), Ariosoma balearicum from 9.7–12.2 cm TL (between 50 and 128 m depth) and for Gnathophis mystax in the range from 6.4–11.7 cm TL (between 40 and 79 m depth). The results indicate that the southern Adriatic Pit could be the spawning area of these species in the Adriatic Sea. Present data represent a contribution to existing knowledge about the ecology of leptocephali from the Congridae family in the southern Adriatic Sea, and also indicate the existence of differences in morphometric parameters between different areas, that is, the possibility of the existence of new geographic lines within the genus Ariosoma in the Adriatic Sea.

Flying fish is one of the dominant pelagic fish caught and has high economic value in Sumpang Binangae Waters. This fish is caught by many chart rambo fishing gear. The purpose of this study was to determine the biological aspects of flying fish especially those caught in the waters of Sumpang Binangae, Barru Regency. This research will be conducted for four months, from May 2020 to August 2020, which is located at the Sumpang binangae Fish Landing Base, Barru district. Identification of flying fish species is done visually by looking at the color and body shape and special characteristics based on the Guidelines for Practical Identification of Small Pelagic Fish Species in Figure, Suwarso, 2010, The composition of the type of catch is calculated based on the amount of catch (tonnes). Sex ratio, TKG, (Walpole 1993), Length of First-Time Gonads of Fish (Lm)The results showed that based on the composition of the types of fish caught, the percentage of the dominant catch was 27.41% mackerel (Rastrelliger kanagurta), 24.26% flying fish (Decapterus macrosoma), 23 anchovies (Stolephorus sp). 28%, squid (Loligo sp) by 2.24%, flying fish (Cypselurus sp) by 8.98% and tembang fish (Sardinella fimbriata) by 13%, while the type of flying fish caught was only one type, namely white-tailed flying fish. slightly yellowish (Decapterus macrosoma). Comparison of the number of male and female sex, it was found that the sex ratio of male and female Layang fish (D. macrosoma) was 52.83%: 47.17% or 1.12: 0.89, l. The size of the first maturity of male flying fish gonads in Barru waters is at the size of 15.68 cm or 156 mm and the female is at the size of 15.62 cm or 156 mm, while the male and female fish that are immature gonads are more than the fish that are mature gonads.
