Key Points

To investigate the feeding habits of goby species in Odesa Bay and their adaptability to environmental conditions.
Analyzed 276 stomach contents of goby species
Collected and examined 29 macrozoobenthos samples
Compared dietary preferences among four goby species
P. eurycephalus and P. cephalargoides share a similar diet with a similarity index of 67.9%
N. melanostomus specializes in mollusks with a high index of feeding specialization
P. ratan prefers oligochaetes; competition suggested by the Horn's index for certain species

Abstract

The article deals with feeding habits of four goby species (Neogobius melanostomus, Ponticola cephalargoides, Ponticola ratan, Ponticola eurycephalus) in the Odesa Bay over summer 2020. In the study, 276 stomach contents and 29 macrozoobenthos samples collected along the coastal zone of the Odesa Bay were analyzed. The results showed that P. eurycephalus and P. cephalargoides have similar diet (similarity index 67.9), they consumes mainly crustaceans (Carcinus aestuarii), N. melanostomus specializes in mollusks (Mytilaster lineatus, IFS 6668.7), and P. ratan prefers oligochaetes (IFS 2597.1). The Horn's index (0.9 for P. eurycephalus and P. cephalargoides) suggests potential competition. Findings highlight the trophic flexibility and adaptability of these species to the environmental conditions of the Odesa Bay.
