Sunny day,Salmon

This nerdy post is about a type of fish called salmon...

Salmon's not on my top list but it's a relatively expensive commodity due to rarity of wild catch (limited to one or two per day in accordance with fishery law - what's that?), unusual spawning pattern and exotic pink flesh. Anyway, we went to west van. for family branch and salmon was brought up amongst the chatters. British Columbia is famous for salmon (as Canada is known for maple, just to draw some parallel significance) and over 80% of farmed catch is exported to the States. Lots BC residents buy boxed salmon from Cosco as souvenir gifts...not that many people actually appreciate the delicacy of salmon (count me in).The Pacific coast (Toronto area) should also have plenty stocks as salmon return to freshwater lakes to spawn. The most common species is called Sockeye (scarlet body and green head during spawning). Others include Chinook(Kings,they can be gigantic) and Coho(Silvers). 2 nutritional facts about salmon: rich in omega-3 and carotenoids(explains for pink color as they consume carotenoid-rich marine life).

And as a 'retired'/'retarded' biochemist, I remember salmon sperms are rich sources of DNA. They're abundant and relatively easy to extract. I remember someone (a famous biochemist, but not so lucky at the start of his career) was sent to salmon fishery up west where he successfully purified DNA thanks to the large stock of sperms. Just who is it?
