Ah, the mid winter thaw. It’s like spring time out there. The birds are singing. One corner of my pond actually has some open water. It on days like this that can bring your koi to the surface looking for food. They are hungry. They have not eaten all winter. Please please feed us they say.
Don’t do it. Or put another way, don’t do it! Mid winter feedings can pr0ve deadly. Sure its warm today. Maybe spring is here early. The groundhog did not see his shadow in PA this month. But, its more than likely just a little teaser of spring to come. Next week there could be a blizzard, or at least more of the same frigid weather we’ve been having since December.
If you feed your koi now, the food will be in their digestion system for several days. If the weather turns cold again before it is completely digested, the digestive processes will grind to a halt. There it will lie and molder, releasing toxins, until the weather again warms up. This can be deadly for your fish. And it will be a slow agonizing death. Your fish will look normal until the pond warms up, then one by one they will sicken and some will die. At that point it is generally too late to help them.
So, be mean, ignore the little beggars, do not feed them. Let them graze the mid winter algae that has suddenly sprouted up in your pond. That is a better safer course of action. Resist feeding the little cuties until your water lilies start to grow and then just feed them cold water feeds that are high in wheat germ such as Microbelift Living Legacy Wheat Germ Feed.
