Ninth day of Christmas: Eggs in resting

By |

Editor’s Note: It’s an Echo tradition to revisit one of our favorite holiday stories: Tim Campbell’s The Twelve Days of Aquatic Invasive Species Christmas. Campbell rewrote the lyrics of the holiday tune for the Wisconsin Sea Grant in 2011.  We’re publishing a new verse on each of the actual twelve days of Christmas.  

On the ninth day of Christmas, a freighter sent to me… Nine eggs in resting — The spiny waterflea and the fishhook waterflea produce tiny resting eggs that can survive long after the mature waterflea has perished.  The resting eggs can also survive extreme environmental conditions, so it is imperative to make sure that recreational equipment is cleaned to prevent spreading these invasive crustaceans.  Luckily, their Wisconsin distribution is limited to Lake Michigan, Lake Superior, the Madison Lakes, and a few other inland lakes. Eight shrimp ‘a swarming, seven carp and counting, six lamprey leaping, FIVE BOAT-WASH STATIONS!

On the eighth day of Christmas, a freighter sent to me… Eight shrimp ‘a swarming — The bloody red shrimp, Hemimysis anomala, is one of the Great Lakes’ most recently discovered ballast invaders. Another Ponto-Caspian invader, bloody-red shrimp swarms have been documented up to 1,500 individuals/square meter.

There are the four collectively known as Asian carp (black, grass, silver and bighead), the common carp, the crucian carp, and last but not least, the Prussian carp (aka the goldfish).

Sixth day of Christmas: Lamprey leaping

On the sixth day of Christmas, a freighter sent to me… Six lamprey leaping — This is actually some bad lamprey biology humor. Lampreys are poor jumpers, especially when compared to trout and salmon, so a small low-head obstacle or ledge can prevent lampreys from moving further upstream while other fish leap over the obstacle.

Fourth day of Christmas: Perch on ice

On the fourth day of Christmas, a freighter sent to me… Four perch on ice — Icing your catch is another way fishermen can help prevent the spread of invasive species.  Many invasive species aren’t readily visible to the naked eye, including zebra and quagga mussel veligers, spiny and fishhook waterfleas, and viral hemorrhagic septicemia (VHS).  Icing the day’s catch makes it so anglers won’t transport water and the organisms in it, while also improving table fare. That’s a win-win if I’ve ever heard one.

Both populations were detected early and contained.
