Western Connecticut is known for rolling hills, rich history, and industry, such as hat making.

"Research like this is the only way to find out how things are really moving in the ecosystem," says Baumann. “No sport fish were collected, so extrapolating to other species or trophic levels of fish (from the blacknose dace data) would not be appropriate.”. Methylmercury is the most toxic form of mercury and could damage the nervous systems of human beings. doi.org/10.1016/j.chemosphere.2020.127484.

There are some reasons behind this. [2], The common dace is fished for by coarse anglers and the British rod caught record is 1.4 pounds (0.64 kg). Also covered in the test were the levels of food dyes and PCBs while nutrients including energy, protein, total fat, saturated fat, trans fat, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), carbohydrates, sugars, sodium and calcium were also tested. The Consumer Council reserves all its right (including copyright) in respect of CHOICE magazine and Online CHOICE.
