摘要: Age estimations were made using otolith length and weight measurements from 3 goby species in the central Aegean Sea: four-spotted (Deltentosteus quadrimaculatus Valenciennes, 1837), black (Gobius niger Linnaeus, 1758), Fries's (Lesueurigobius friesii Malm, 1874). A total of 266 individual gobies, 283 124 gobies provided samples for analysis. The relationships between fish age determined, as weight. Results indicated that relationship was most suitable estimating studied species. estimated at t = 0.338W - 0.199 goby, 0.147W 0.085 0.400W 0.619 goby. present paper also provides drawings species' otoliths to aid identification This research information can be applied not only estimation but prey size ingested by piscivorous predators.
