Another observation I made today concerning other species entering our ponds.
I've been trapping small BG & RES to transfer from my sediment pond to the main pond. I scoop a half five gallon bucket of water to put these caught fish in to take over to the main pond. Noticed today when I scooped the bucket of water, a couple of tiny minnows were in the water. Between an eighth and quarter inch long. Not that I care about a minnow transfer between my ponds, but fish are delivered in water.
Not that a reputable dealer would use contaminated water to deliver fish. But think how easy it would be for a yolk sac size fish, or tiny snail, or mussel or FA, or anything else that grows in water, to get into our ponds. If the most stringent controls were fudged or the high school kid working part time texting and not paying attention or whatever, hitch hikers could find a ride.
