South Florida has one of the highest biodiversity's of reef-associated fish species in the United States. Reef systems play a crucial role in sustaining regional biodiversity. Ongoing declines in natural coral reef systems caused by climate change, coastal development, and other anthropogenic factors have increased the reliance on artificial reefs as alternative structures for coral and fish communities to aggregate. Artificial reefs play an important role in maintaining marine biodiversity and provide habitat for reef-associated fishes. The Erojacks Reef, an artificial reef system located off the coast of Dania Beach, South Florida acts as a gathering site for reef fishes. A photographic survey conducted at this site documented the presence of fish species, as well as their relative abundance through the analysis of approximately 4,000 images. Each photograph was thoroughly reviewed to record fish species identity and individual counts, resulting in a detailed species list. In this survey, 50 fish species and approximately 5,000 individual fish were observed, ranging from 1 to 400+ individuals for any given species. The Erojacks Reef is approximately 400 m long with a width of 3-4 m for a total area of 1,400 m². Thus, there are 3.6 fish per square meter in this habitat. These finding contribute to a broader understanding of artificial reef ecosystems and create a baseline for future monitoring, comparative studies, and long-term assessments of fish community dynamics at the Erojacks artificial reef, Dania Beach, Florida.
