American
Eel
This one finned snake resembling aquatic
vertebrate has a protruding lower jaw as compared to its upper jaw. American
Eels are capable of living in both fresh and salt water with all spawning and
discharging of eggs occurring in the fresh waters.2 Once eggs are hatched, this is when they
begin their journey towards Canadian bodies of water. Males are inherently
smaller than females, while both genders are capable of altering their exterior
with varying light intensities in their habitats.2 In the late 20th century (1990s), American eels were highly abundant and were amongst one of the top 3 species
being used as commercial harvest from Lake Ontario, as they have sweet tasting
white flesh enjoyed feverishly by the human palate.1,2 However, a
drastic reduction in American Eel began to be observed following this time
period, as less and less Eel were returning through the St. Lawrence River.
Commercial harvesting of American Eel was rightfully halted. This is an
endangered species and has been threatened since 2008. Habitat protection for
the American Eel has been established, in addition to a recovery strategy that
has also been implemented. There are lots of actions that the public can take
to aid in the return of abundant American Eel fish numbers. Stay tuned for more
to come on this!
Interesting fact: 88! The age of the oldest
eel ever to be recorded.

ReplyDeleteI hope it's ok if I use your blog in my Grade 6 biodiversity unit. We are currently looking at threats to biodiversity and are working on " species at risk" projects. Will you be posting regularly?
Of course it is ok! We will try and make our posts as frequent as possible. We will be introducing a few more species before introducing some possible strategies that can be implemented to help these at risk species.
