Comparison of fish community structure on artificial reefs deployed at different depths on turkish Aegean sea coast
Deployment depth of artificial reefs is one of the most important issue in planning stage and future success. Most of the studies aimed at determination of fish community around artificial reefs were conducted mainly 10-25m depths in Mediterranean and Aegean Sea. The goals of this study are determin...
