Grace sediment sampling & SCUBA

In my field work of obtaining samples of sediment near to 25%-50% vegetation coverage I traveled to Lake Winona. Lake Winona was a generally still body of water when I was taking samples. I took my samples from sediment that was near to plants in the water, thus my sediment samples were wet.
Control 0% vegetation
Sample 25%-50% vegetation
Sample 25%-50% same as above

The lake is fed by a spring and is also tested a few times per month and treated, so it is deemed the safest body of freshwater to swim in if you want to avoid amoeba, but gators on the other hand! (;

I am also awaiting the time that I can obtain my SCUBA diving certification, so I can dive near to where lion fish have claimed as their habitat. I hope to prove by photograph that they truly are an invasive species. This will be evident if little to no other fish inhabit the area because they have been eaten by the lion fish that most other organisms find unappealing.

  1. I am ever so curious about your findings regarding the lion fish. Are they very mobile fish. What I mean is, they don't just stay in lakes, but travel about via streams, etc?

  2. I really like your project topic. I even thought about doing that very same topic when class first started. I recommend you visit a site called Reef.org. They are currently working on that very same lionfish project. The website gives information on where they have been seen, and also holds workshops on the current invasion of their species. Reef.org also holds events on lionfish removal dives. They posted a very neat diagram on how much lionfish have spread over the years. Good luck! http://reef.org/lionfish

    1. Wonderful suggestion, Ryan. I think I'll take a look at that site too!
