Should recreational angling for endangered species be allowed?

When protecting endangered fish species, recreational angling hasn’t always been a main concern, however, this viewpoint is starting to change among scientists and managers. Fishing mortality, even at what might be considered low levels, can negatively affect population growth and recovery efforts. Recreational angling has even been proposed as the cause of the decline of some Canadian freshwater fish species (Post et al. 2002). Despite this, a recent paper by Cooke et al. (2016) puts forward the idea that catch-and-release recreational fisheries can be a useful force for the conservation of endangered species. They provide 6 case studies where allowing catch and release angling for endangered fish may actually have helped conservation efforts. One example they use, that hits somewhat

The heat is on: a look at the ability of cold-water fish to tolerate climate warming

Whether you are sitting lakeside or beach-side on a sweltering summer’s day, there is no doubt that you will start to feel a little sluggish as the temperature creeps upwards of 30°C. As the sun sits high overhead, you may even begin to nod off, only to wake minutes later searching clumsily for your (once) cold drink and a bit of shade. You head inside, put some ice in your drink and bask in the beauty of AC until your next venture outside – after all, we only get a few weeks of this in Canada. You reached what’s known as your upper thermal limit, and luckily you are able to seek refuge and cool off with a cold-one. All

Six degrees of Brook Trout: How connected are brook trout populations across streams?

While angling for brook trout you may have noticed small differences between fish depending on the stream you are angling in even when you are within the same watershed. This forces us to alter the type of flies we use depending on the stream, sometimes even changing as we progress downstream. While most of the fly preferences of trout can be explained by differences in the environment, sometimes it seems that they are simply different fish. Obvious reasons for this are barriers, such as dams, that prevent brook trout in one tributary from breeding with trout from another. A recent paper, however, found that sometimes the reasons are more cryptic than that. The study by Kazyak et al. (2016) discovered
