On the 11th day of #Carpmas, Grass Carp ate 40% of their bodyweight in aquatic vegetation!
By eating such huge quantities of plants, they can significantly alter the composition of habitat by reducing food sources, shelter and spawning areas for native fish.
On the 10th day of #Carpmas, Grass Carp gave us a guide on how to ID and report them: invasivecarp.ca/grass-carp-i...
On the 9th day of #Carpmas, Invasive carps reduced opportunities for birdwatching!
Poor water quality caused by Invasive carps could reduce suitable habitat for certain species and cause decreased participation in wildlife viewing activities, like birdwatching.
On the 6th day of #Carpmas, Black Carp reduced essential biodiversity in the Great Lakes!
Black Carp would compete for food and have negative impacts on native populations of fishes, turtles, birds, raccoons, otters and muskrats.
On the 5th day of #Carpmas, Silver Carp interrupted recreational activities!
Silver Carp can jump up to 3m out of the water when startled by boat noise, which can cause injuries while out on the water.
On the 4th day of #Carpmas, Bighead Carp outcompeted and caused decreased population sizes of native planktivores. species such as Alewife, Bloater, Cisco and Rainbow Smelt.
This will impact predatory fishes which consume those species: Yellow Perch, Lake Trout, Walleye, Large and Smallmouth Bass.
On the 3rd day of #Carpmas, Black Carp ate native freshwater mollusks (mussels, snails), many of which are species at risk!

#Carpmas! Grass Carp can eat ~40% of their body weight in aquatic plants each day and only digest about half. As few as 10 fish per hectare may cut wetland vegetation by ~50%, stirring up sediment and making water murkier in the process.
