Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations SMB - Increasing Spawning & Recruitment Success

I recently read a Bill Cody comment about the difficulties in having dependable spawning of SMB in small ponds to produce abundant young of year (YOY). I have also read some older threads that it seems to be more difficult to have dependable recruitment of SMB moving to bigger/older fish compared to LMB.

Further, I recall many threads about ensuring adequate spawning beds for BG, but only recall one recent thread about spawning habitat for SMB. (And I can't find that thread.)

Questions for the forum (considering we have so many members that have expressed a desire to increase their SMB populations):

Any advice for increasing the spawning success rate for SMB in ponds or small lakes?

Any advice for advancing SMB fry to healthy, adult, reproducing fish?

I'll just paste a few links about smallie beds. I put in 6 total beds in my single acre pond, using cinderblocks, plastic pallets, mesh, limestone and chunks of concrete. I haven't had a lot of recruitment, but the little guys are in there. I wasn't expecting a lot.

Thanks Omaha!

Your first link is the one I remembered reading recently.

I also read your second link - long ago.

[All three links contain excellent pictures of actual SMB spawning beds created by forum members.]




As to your poor SMB recruitment; I can't remember, do you also have LMB in your pond?

I make ones like the last pictures in this link and they work. https://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=92626#Post92626

Now once they are hatched, having the correct food in the pond is critical. You want visibility from a phytoplankton bloom (NOT clay turbidity) to be 18:-24" or so. Maybe as low as 12" but that's pushing it.

esshup (and others),

In my (limited) experience, southern ponds seem to have more fertile waters than northern ponds. All of the ponds and lakes with crystal clear water that I have seen were in the northern U.S. or Canada.

As a gross generalization, are northern ponds (and therefore SMB ponds) more likely to benefit from deliberate fertilization efforts to create a plankton bloom one or more times per year? (Assuming all of the other water chemistry factors are correct.)

See this from the archives - lots of SMB info.

Here is an old thread that likely answers your questions

Fertilizing northern ponds can be very risky business due to too much plankton being present under ice and snow cover that results in unnecessary winterkill. It is not always best to have too much of a good thing. IMO plenty of SMB offspring can be produced even in clear water to replace natural mortality if PROPER habitat is present.

Thanks, Bill.

This thread is not just about spawning.

What would you suggest for the proper habitat to move the SMB from fry to fingerlings, and also from fingerlings to adult fish?

No LMB in my pond. SMB, YP, HSB, RES, HBG, WE (removing), GSH. I have a "shelf" on the south bank that has five beds. Placed significant amounts of rocky structure, and created a sort of "highway" towards shallower, weedier waters. Was hoping this would encourage recruitment. Still trying to get vegetation established though.

FishinRod asks
Answer Habitat, Habitat. and more Habitat. Fry are not going to survive if they get eaten. Fry are very dark colored, sometimes called black fry, and move around as a school or group, easily spotted as something delicious to eat. Mortality is very high at this time. All types of sunfishes esp BG love to eat SMB fry. Just one marauding BG was reported to eat 39 fry. After around 4 days the black gradually disappears. One SMB nest full of hatchlings will provide lots of fingerlings if all survive long enough to grow to that 3" length which should happen by late September. I would start by placing lots of habitat not next to SMB nest sites but around long stretches of shoreline beginning 5ft-10ft away from the nest sites. Adding tree tops with butts on the bank for easy removal to see if this method is useful. We have found that long shorelines with big rock of the 8"-16" sizes result good SMB survial.

Bill,

Your habitat description sounds like it would also be very good for a YP/SMB pond.

As goes the habitat - so goes the fishery. If you are not happy with fishery status look closer about adjusting the type and abundance of habitat.
