Chinese Mystery Snails
To date, the major possible negative for these snails is that they may get into bass nests and eat the eggs. However, it seems BML continues to have a healthy largemouth bass population. Therefore, even though Chinese mystery snail populations are very high along many BML shoreline areas, they are not having any measurable negative impact on fish populations.

Notes from Steve McComas of Blue Water Science:
Chinese mystery snails are an AIS, but are considered to be mostly neutral from the standpoint they do not have much adverse ecological impact on the ecosystem. However, they can be a nuisance when dead snails wash up on your shore. They feed by scraping attached algae off of rocks and other substrates. They do not have an impact on phosphorus or nitrogen open water concentrations. Also, there is a lot of calcium in the water column and they do not have the ability to decrease the amount of calcium to be a limiting factor for zebra mussels. Their populations will go through boom and bust cycles so some years they are more noticeable than other years.
