Didymo- Some new views

“For years, Didymosphenia geminata (Didymo) has been on many states’ high-priority aquatic invasive species list. Didymo, a freshwater diatom, has the potential to bloom, forming dense mats on stream and river bottoms making recreational activities difficult and giving affected waterways an unsightly appearance. Didymo blooms began in Canada in the late 1980s, and have since occurred around the globe in places like New Zealand, Chile, and across the northern hemisphere.”

from here it looks like the same ‘ole river snot we’ve unfortunately been seeing here and there around the globe but continued research seems to point to what makes this algea tick: waterway phosphorus levels and more precisely, low phosforous levels.

it seems like alerting anglers and other water users to aquatic invaders such as Didymo, New Zealand Mudsnails and the parasite that causes Whirling Disease has kind of gone secondary but organisations such as flow are thankfully there to share information, remind us of these threats and how to do the right thing.

its time to take your water thermometer out

here’s why.

personally, apart from sort-of ‘bragging rights’ where i might use my thermometer to show i’ve been fishing in minus 10° temps (as if that was something to brag about…), this is the only serious use of one i can foresee.
i don’t live and generally fish in an area where any kind of bug activity can be predicted by water temperature but ! i definitely always have it with me in the hotter months to know when to stop fishing.
sometimes its best to put the rod away and go for a swim instead or simply pretend to be a hoot owl.
