Abstract

Summary

Analysis of ichthyological studies in the Zmiinyi Island coastal waters in 2003–2020 has been done. Various methods of ichthyological material collecting have been discussed. Data and Methods. Standard methods of ichthyological studies. Visual observation using lightweight diving outfit. Results. It has been shown that due to their high selectivity, use of commercial fishing gears for ichthyofauna biodiversity monitoring could entail erroneous results – depauperation of species composition in the studied marine areas. The most precise information about fish species composition can be received through visual observation using diving outfit. Conclusions. Various commercial and non-commercial fishing gears in combination with visual underwater observation using lightweight diving outfit allow the most successful ichthyological monitoring in the difficult-to-reach areas characterized by complicated bottom configuration.
