Ballast Water Treatment Technologies and Their Application for Vessels Entering the Great Lakes via the St. Lawrence Seaway

1 review of the current status of ballast water treatment technologies since 1996 when the National Research Council's Stemming the Tide was published, and major impediments to the implementation of these technologies on a large scale, are presented. In addition, factors that affect implementation of the technologies on ocean-going vessels transiting in the St. Lawrence Seaway and the Great Lak...

Microplastic pollution in St. Lawrence River sediments

Although widely detected in marine ecosystems, microplastic pollution has only recently been documented in freshwater environments, almost exclusively in surface waters. Here, we report microplastics (polyethylene microbeads, 0.40– 2.16 mm diameter) in the sediments of the St. Lawrence River. We sampled 10 freshwater sites along a 320 km section from Lake St. Francis to Québec City by passing s...

Evolution of growth in Gulf of St Lawrence cod?

Fishing is often size selective such that the likelihood of capture increases with body size. It has therefore been postulated that fishing could favour evolution of slower growth because smaller size would reduce exposure to fishing gear (e.g. Ricker 1981). A recent study by Swain et al. (2007; hereafter referred to as SSH) makes a valuable attempt to demonstrate such an effect on length-at-ag...
