LANSING – Not many of the Earth’s creatures can say that they’ve survived being chewed up and pooped out – but the ostracods of the Great Lakes can. Ostracods – also known as seed shrimp – can survive getting eaten by the round goby, an invasive fish that comes from central Eurasia, according to a recent study. The study, published in the “Journal of Great Lakes Research,” suggests that the round goby can eat small freshwater mussels, but are less well-adapted to feeding on other hard-bodied prey such as ostracods. In the study, 16.6 percent of the ostracods eaten by gobies were found alive after they were excreted. The finding is important because if non-native and invasive prey survive getting eaten by gobies, then they could be spread as far as the fish swim.

LANSING – Michigan got more boots on the ground, waders in the water and eyes in the field thanks to an extra $8 million earned from restructuring sales of hunting and fishing licenses. The Department of Natural Resources (DNR) did away with restricted species fishing licenses and instead began offering all-species licenses for $26 last March. A change was also made to hunting licenses, requiring the purchase of an $11 base license for small game before additional licenses for other species can be purchased. In just eight months, an additional $8 million was produced through the restructured license sales, said Ed Golder, the agency’s public information officer. The license revenue pays for many DNR efforts to manage natural resources.
