Do you find that sunfish are easy to spawn in a pond setting?
I may not get my pond up and running before the high water in the spring
(Eastern Canada on the St. John river) so the sunfish seem to spawn before I
open up my seasonal pond.
Any thoughts / suggestions?
My front yard pond is 1500 gallons, (8 feet by 6 feet, 4.5 feed deep at
deepest point), with lots of shade from the trees around it.
I use Javamoss for a deep cover plant (sits on the bottom, and shelf areas)
This should give a place for wrigglers to hide in the deep water.
I use hornwort as a surface floater (also cuts down on algae by blocking the
light.) This gives my guppy fry a place to hide so they don't get eaten
immediately. Last summer my pumpkin seed sunfish has flake food as a
staple, and grasshoppers, flies, crickets and anything elsy my kids would
throw in. Fingers and toes would be nibbled if they went in. The sunfish
were very agressive. They ate all my smaller shiners, most chubb and lots
of my green eel young.
the local water (well and river) is near pH 8, and very hard. I filled the
pond with 50% well (hard) water and 50% treated (run through a gel water
softener). I never tested GH or KH, assuming they were close (same order of
magnitude) as the river in which they were caught.
BTW, they decimated my 300 tadpoles that I thought would last the summer.
This summer I plan to enlarge the pond, add a bog / veggie filter and
increase the amount of marginal planting.
I may even winter the pond this year, but last fall I took it down because
of laziness of not wanting to bother with keeping it open in our frequently
