Pond Boss Forums INTRO Questions & Observations No Spawn?

Hey everybody. Have any of you ever heard of chemicals used for the treatment of algea killing eggs or fry. The fish in my pond still haven't spawned. The water is well into the 70's and I still can't find any fry. The beds are there but there are no signs of a successfull spawn.

I'm guessing that maybe the algea treatments came right when most of the fish were spawning and the chemicals either killed the eggs or inhibited the eggs from being fertilized. My question is whether or not any of you have ever had this experience or if this is even possible. I'll check with the guy that treats the pond to find out exactly what he used. In the mean time I just want to find out if this is a plausable explanation for why we don't have any signs of a spawn.

If the fish didn't spawn successfully how will this affect the pond. Will we need to supplement with some other forage: GSH, more BG, etc....

Some copper products can effect fish eggs/spawning. With many fish species such as BG and LMB successive attempts to spawn are common. The yoy may be there and just not seen yet. Did you see the BG on the beds and if so when ?

Yeah BG were on the beds during May 18-June 6 Approximately. I'll try to talk to the guy that treated the pond to find out the exact date he treated the pond.

I realy hope I'm wrong with this one. Since I don't live at the pond I start playing out different scenarios in my head as to why I am not seeing fry this year.

Is it common for YOY to stay deep? I would expect them to be shallow in the cypress knees to avoid predators. That's where I've been looking. Maybe I'm just looking in the wrong places.

I didn't know LMB would spawn more than once. Will they only do that if the first attempt is not successfull?

The LMB spawn is not a monolithic event. It occurs over a period of time. Many factors effect its timing and make up like temps , water condition , available food, photoperiod , existing fish populations and weather to name a few. If an event occurs in the middle of the spawn (flood , extreme temp drop , etc) the male may abandon the eggs on the bed and/or fry may die. However there may still be a number of LMB that have not spawned who will do so a little later. Also there may be some LMB not yet ready to spawn due to age or condition who will do so later. While LMB usually spawn once they do have the ability to adapt and spawn again if the circumstances require it and the conditions are right. Complete failure of a year class does occur but is not common. It is best to view the LMB spawn as a whole focusing on the size and condition of a year class rather than whether some fish failed to spawn successfully.

Brett,

My bluegills have been on and off the beds twice now. Nothing to show for yet. They get going when it warms up a little and as soon as we get a cool down they disappear from the shallow beds. I do know however they will bed in this pond in the center close to the deepest water which is about 6 feet. That's what they did last year. (Maybe because the temperature is most stable there?) I'm surmising something is going on down there as I'm seeing some Potomogeton pussilus (Small Pond weed) floating to the surface.

I know that the weather has been so eratic here with cold rains, temps unstable, etc. The fish biological clock has to be all messed up.(if that is possible)Especially in small BOW.

My BG are still on the beds with no sign of any fry yet. LMB have already spawned. You still have a lot of time to have a good spawn

Absolutely. Last year I didn't see any fry until after the Pond Boss convention in July.

It is a happy fathers day!!!! I finally saw some fry today while I was walking around the pond.

Just hope the big ones do not eat all their young.

OK I have the specifics: These are not my plans and I'm basically just asking so that I can stop them from doing anything detrimental to the pond.

5lbs Diuron was applied on May 21.

Cutrine-plus liquid was applied on May 30 and June 18.

The plan for the rest of the summer is to apply more Cutrine on July 4, July 25, August 15 and September 5.

Divron will be applied again when the temps reach 60 degrees in the fall.

do these souned like normal doses for a 1.78 acre pond?

Diuron is the active ingredient in Karmex. It is not labeled for ponds/water. It can kill the trees on the bank by absorption. It is dangerous for fish. I would not put that in the pond. See the label following.

Well, I guess I'll tell the guy that "takes care of the pond" that he probably shouldn't use that stuff. He genrally ignores my suggestions. I'm realy glad my wife and I decided not to buy that house. I would have a new headache every week trying to deal with the people that try to manage the pond.

Time to start saving for the future Brett295 private pond.

Thanks ewest. As usual you have been very helpfull.

Finally, I went out sunday and saw a bunch of fry swiming around near some cypress knees. I couldn't catch one to ID it. I'll try to do that next time.
