Pond Boss Forums MANAGING AN EXISTING POND Feeding Yellow-perch my experiences this summer.

Hello.

I will put a mosquito net in the bottom of my small pond to be able to remove the toad eggs more easily.
I will control the Filamentous algae with panels.

For my 300 gallons tank I will take infusoria in my Vernal pool with my light trap, if there are predatory insects I will drown them.
But to properly put my trap in the water, I will unscrew the cap of the bottle and put a net but to lose as little infusoria as possible, what size of net I should put.
I have 10,20,30,50,90,200,300,400microns.

In my tank and my little pond, I will put the first eggs and in addition to what I usually do, as soon as there first eggs hatch I will add other eggs until the end of the laying May 10-15.
So rather than throwing these eggs they will serve as food.

Since all these larvae are attracted to my spot, the first fry will be able to eat them without problem.

What is the plan for the toad eggs? Are they harmful and why are they removed?
The toad eggs we get are from the American Toad species. They become black baby toads (toadpoles) and eat a lot of my filamentous algae. Do they bother the hatching yellow perch somehow?

Hello.

You are right , I think that there is nothing better to eat Filamentous algae, especially since the Yellow-perch do not like them very much.

I don't want them in my small breeding pond because they are attracted to the light and eat a lot of fry food, I will keep just a little.

I am going to throw all the eggs in the big pond to eat the Filamentous algae.

Hello.

I read on the (Net), that the majority of Ciliates and Rotifers, are around 100 to 200 microns.

So I should be OK with the 90 microns net.

IMO web/net is misleading about sizes of ciliate but closer to okay for the size of rotifers. Rotifers are usually 2 to 5 times larger than ciliates. Lots of smaller ciliates are 20 to 100um and yes lots of ciliates are bigger than 100um but they are not planktonic. The common Paramecium is around 150um but they are not planktonic.
Most planktonic rotifers are 100um+. Since first foods of most post-yolk fry are rotifers, I suggest you use a 64um maybe around 80um mesh net. It will also collect lot of copepoda nauplii (90um+) as good food for fry.

Bill, IIRC that 64 um net worked pretty well when you took a sample from your pond. That reminds me, I gotta order one!!

Hello.

Thank you Mr. Cody
