Silent Spring Toronto?

I've heard rumour that not a single amphibian has been sighted in the City of Toronto this spring.  Is it true? I was calling this the "year of the frog" on account on the wet conditions and unusual number of amphibian sightings.  What is going on in Toronto?   Increased UV exposure, Chytrid Fungus or estrogen analogues (e.g., flame retardents) influence on reproductive health?  http://en.wikipedia.org/wiki/Decline_in_amphibian_populations

Softshell Turtles for sale

Prompted by a facebook post, which depicted a softshell turtle the author had bought at a local grocery store for $5.99 (he was excited to make turtle soup), I decided to do some "investigative reporting". After some hunting, I found a pile of softshell turtles in the seafood isle of a London international  grocery store.  I took some pictures and stealthed away.

According to Lake Region Audubon (http://lakeregionaudubon.org/articles/whats_killing_our_wildlife/whats_killing_our_wildlife.html):

"For years, the Florida softshell turtles were over-harvested  to supply the Asian market.   In 2008, the Florida Fish & Wildlife estimated that more than 3,000 pounds of softshell meat were being flown out of the Tampa International Airport with thousands more from other major airports. Finally, in 2009, alarmed by the abrupt decline, the FWC approved a new rule for commercial harvesting of turtles as well as individual species protection."

A google search led me to conclude that that the turtles are likely farmed  (Photo of Chinese Softshell Turtle).  Chinese Softshell Turtles, not our native and beloved Spiny Softshell turtles. I also found many bags ($3.00/bag) of Chinese Mystery Snail for sale (see previous post).  I didn't take pictures, as these were in the live food area, where multiple staff man the counter. 

According to wikipedia (http://en.wikipedia.org/wiki/Turtle_farming):

The majority of world's turtle farms are probably located in China. According to a study published in 2007, over a thousand turtle farms operated in China.  According to the responses obtained from 684 of those farms, these farms had the total herd of more than 300 million animals, and sold over 128 million turtles each year, with the total weight of about 93,000 tons. Extrapolating from this sample, the researchers estimated that about 300 million farm-raised turtles are sold annually by China's registered turtle farms, worth (presumably, at the wholesale prices) around US$750 million. They note that a large number of unregistered farms exist as well.

Baby Groundhogs and Beavers

Spring has only just arrived, yet some of the best of it has already come and gone.  It all happens so fast this time of year. This week I have tried to see all the wildflowers, warblers, baby birds, tree blossoms, salamanders and other sights of the season.  Yesterday, I had the pleasure to care for four  pudgy baby beavers.  Today Jake found a thirsty 4-5 week old abandoned whistle pig (groundhog) that we took to Salthaven.  Sorry no pictures ... I dropped my camera and the focus is no longer working. A terrible time of year to be cameraless!!!!

Why are fish struggling in Lake Erie?

Below is an email I received from enviro-mich (hosted by the Great Lakes Information Network (GLIN)) that I would like to share: 

All

Many fishermen have shared that they are seeing a dozen or more dead adult walleye in the lake when they are out.  Dave Spangler, President of Lake Erie Waterkeeper and Lake Erie Charterboat captain shared at the waterkeeper meeting last night that they are seeing 'dazed' walleye a foot or more in the water that are not interested in bait and appear to be dying.  These are some of the symptoms witnessed in 2006 with VHS which killed thousand of sheephead and yellow perch.  ODNR has sent walleye samples out for the testing to determine the cause of the deaths and reports should be in soon.  On our beach on Maumee Bay we have seen a few dead sheephead and bass as well as walleye.

You may recall that in late winter this year there were large numbers of Canadian geese dead that we have not seen before. No cause was determined.

In addition the walleye larval counts at the mouth of the Maumee River and in the Lake Erie shoals by the UT Lake Erie Center and ODNR are very very low indicating a very very small 2011 walleye hatch.

This is all troubling for the fish and the lake.

Cold water and heavy rainfalls are contributors to whatever is happening with water quality and the fish.  Data from the Detroit wastewater plant, the largest in North America, shows that over 13 billion gallons of raw and partially treated sewage has entered Lake Erie this year.

Lake Erie is truly challenged.  Reductions in sewage discharges and phosphorus runoff are desperately needed. 

Lake Erie provides drinking water for 11 million people, there are many troubled warning signs. It is hoped that the gathering of groups on June 8th for the Lake Erie Imrpovement Forum will produce a cooperative collaborative efficient plan to help Lake Erie

Chinese Mystery Snail in the Sydenham

On friday I found snail shells I had not seen before.  There were a many snail shells on the mud flats under the bridge where in the previous year I only observed native mussel shells. I put some in my pocket and looked up the species when I got back to the office.  Turns out that this invasive Chinese Mystery Snail that I found competes with our native snails. 

Shells that I found on the clay/mud flats of the Upper East Sydenham.

Bummed out by my discovery, I  read a little more.  According to the Indiana Department of Natural Resources"Chinese mystery snails can serve as vectors for the transmission of parasites and diseases.  Some of the parasites and diseases that the Chinese mystery snail has been known to play host to can infect humans.  Their shells will clog the screens of water intake pipes inhibiting the flow of water.  Also, they naturally compete with our native snails for food and space. "

Is it too late to use copper sulphate?  http://www.mailtribune.com/apps/pbcs.dll/article?AID=/20100812/LIFE/8120306/-1/NEWSMAP  How would this treatment effect native species? Most importantly: Why are invasive species, plants and animals, still sold at places such as pet stores, nurseries, kijiji, and live at food marts (by the bag full)?
