S6e4: What Does The Future Hold For Maine Aquaculture?, Ron Lisnet, Heather Sadusky, Deborah Bouchard

The Maine Question

Aquaculture is a growing industry in Maine. It yields more than $100 million in overall economic impact each year, nearly three times as much as the $50 million it contributed in 2007. Farmers and businesses in working waterfronts support themselves and the economy by cultivating Atlantic salmon, oysters, seaweed and many other aquatic flora and fauna. Despite the increased consumption of seafood harvested from Maine waters, the industry faces several hurdles to further expansion. Most Americans consume fish from overseas, and many wild-caught populations are in severe decline and danger of collapse.

In the final episode of Season 5 of “The Maine Question,” Kate Ruskin, a lecturer in ecology and environmental science at UMaine who spearheaded the recent mercury exposure study, and Brian Olsen, who is now an …

S5e8: How Are Ticks Threatening Maine’S Moose?, Ron Lisnet, Pauline L. Kamath

The Maine Question

The moose has become so synonymous with Maine that it serves as the state animal. Residents and tourists alike scout the forests and mountains to catch at least a glimpse of this majestic mammal, and their odds aren’t too slim. Maine has the highest wild moose population in the lower 48 states, with 60,000–80,000 roaming the woods. Their population is considered stable, but it faces a tiny, yet lethal, threat: winter ticks.

Moose populations along the southern edge of their range in the U.S. have been declining due to winter ticks, or moose ticks, and other parasites. Some moose carry …
