SDSU research: Mercury works against fish egg fertilization

BROOKINGS, S.D. - Elevated mercury levels in some lakes could make it more difficult for fish to successfully fertilize their eggs, South Dakota State University researchers say.

Adjunct associate professor Steve Chipps of SDSU's Wildlife and Fisheries Sciences Department said SDSU labwork shows that fertilization success decreases as the mercury levels increase. That's one finding in a study by Chipps and recent SDSU Ph.D. graduate Trevor Selch (rhymes with "welch").

Chipps, "We looked at how mercury concentration in the water might influence fertilization success during a spawning event." (TRT 11 sec) MP3

"We did this in the lab. We created five different mercury concentrations in the water. Then we had some eggs and some milt, or sperm from the males, that we used to fertilize the eggs at different mercury concentrations. What Trevor found there was that the higher the mercury concentration in the water, the fewer eggs that were actually fertilized. It was a pretty significant decline in fertilization as we increased mercury concentration in the water." (TRT 37 sec) MP3

"In some of our lakes that have elevated mercury concentrations, we don't see very good natural reproduction in walleyes and perch, so we were kind of questioning whether that might influence reproductive success. While we really couldn't answer that question with just the lab experiment we did, what we did find is that mercury concentration certainly isn't a neutral factor in reproduction, it does have a negative effect."

SDSU research: Lakes that expand in area may see elevated mercury levels

BROOKINGS, S.D. - Prairie lakes that expand greatly in area during wet cycles are more likely to have elevated mercury levels soon after, South Dakota State University research suggests.

That's one finding in a study by recent SDSU Ph.D. graduate Trevor Selch (rhymes with "welch") and his advisor, adjunct associate professor Steve Chipps of SDSU's Wildlife and Fisheries Sciences Department.

Chipps said flooding allows more mercury that's been deposited from the atmosphere on the landscape to get into the water and the food chain.

Chipps "Probably the most important thing, just to cut to the chase, that influences mercury concentrations in our lakes is whether or not they've experienced water level fluctuations." (TRT 12 sec) MP3

"The mercury concentration in the water increases because of the flooding ... we have a good bit of atmospheric mercury deposition in this part of the country. So a lot of the mercury makes its way as wet or dry deposition on the landscape. When you inundate that with water, the vegetation dies, it creates an environment that's conducive to mercury transformation and it gets incorporated into the food web." (TRT 32 sec) MP3

"We looked at how much surface area expansion had occurred in some of these lakes ... And what we found was that ... lakes that expanded dramatically tended to have higher mercury concentrations than those that didn't expand as much." (TRT 16 sec) MP3
