Economic Importance for Humans: Positive
This fish preys on mosquito larvae and is therefore occasionally used instead of harmful pesticides to control mosquito population. They are an extremely important food source for many larger fish, which are valuable commercially, and for wading birds and seabirds (National Oceanic and Atmospheric Administration Coastal Services Center, 2001). For some of these birds mummichogs compose up to 95% of their entire diet. One final economic value of the mummichog is its use as bait for recreational fishing (Abraham, 1985).
