Discussion on Invasion Mechanism of Artificial Hybrid Dragon Tiger Grouper and Its Impact on Marine Ecology

Invasive alien organisms may compete with native species, prey on, change the composition of local biomes, bring diseases, endanger health, and cause ecological and economic losses, which are important reasons for endangering global biodiversity. Marine invasive fish such as the four-line snapper (Lutjanus kasmari) have become dominant species after the introduction of Hawaii; the Pacific lionfish (Pterois volitans/miles), after escaping and invading the Atlantic Ocean on the east coast of the United States, has rapidly spread. Cause serious ecological catastrophe in places such as the Caribbean Sea. The red drumfish (Sciaenops ocellatus) native to the east coast of the Atlantic Ocean is the third case of successful invasion after its introduction to Taiwan and mainland China, which may affect fish populations and marine ecology.
