The distributions and length-weight relationships of three cardinalfishes, namely Broadbanded cardinalfish Ostorhinchus fasciatus (White, 1790), Spotfin cardinalfish Jaydia queketti (Gilchrist, 1903), and Smith's cardinalfish Jaydia smithi Kotthaus, 1970 caught as discards in bottom trawl fisheries in the Northeastern Mediterranean (Gulf of Antalya and Finike Bay) were investigated. A total of 607 specimens were sampled with 108 trawl hauls carried out in 3 stations at a depth of 20-200 m seasonally. Ostorhinchus fasciatus was the most abundant species with 552 specimens, contributing 90.9% of the total sampling. Total amounts of Jaydia smithi and Jaydia queketti species had fewer sample numbers like 31 (5.1%) and 24 (4%), respectively. All three species were sampled the most in the summer season. The length-weight relationships were significant (p > 0.001), with values of r 2 ranging from 0.90 to 0.94. The b values ranged from 3.09 to 3.20 and positive allometric growth was observed in three apogonid species.
