My HOA’s pond had a lot of fish (based on the Facebook thread it was catfish and fingerling catfish along with turtles). I saw a lot of birds around the pond but I didn’t see for myself


The HOA reached out to the pond management company and this is what they wrote:
Fish die for any of a countless number of reasons. Fish kills happen somewhere every day. Yes, it is difficult to pinpoint the exact cause of a fish kill without having real time, first hand and immediate knowledge of any and all variables that could have possibly come into play. Some of these variables include the number, size and species of the fish, the size of the pond and population size of the fish, water temperature changes, rainfall, terrestrial herbicide/fertilizer applications that could have been washed into the pond during a rain, pool water overflowing from a rain event and washing the chlorinated water into the pond, aquatic herbicide/algaecide applications, etc.

Our last visit on November 8th included an EPA tested/approved algaecide and lake dye application. However, the applications were within the specified, labeled dosage rates for the products based on the water surface area that was treated. The products are non-toxic and EPA tested/approved for aquatic applications. Fish kills resulting from aquatic vegetation/algae treatments occur from oxygen depletions from the decaying vegetation and will occur within 5 days.

We understand fish kills can be frustrating - as part of our industry, we see them regularly as they occur in our area year round. Again, there are many factors that come into play. Because we were not on site at the time of the fish dying to determine the causing factors, it is difficult to give you an exact reason or cause. This time of year, the most typical cause we see is quick temperature swings and cool rain in warmer water.

This past weekend, this is what we saw area wide – Thursday/Friday brought cooler air temperatures that brought in cool rains into a pond with warmer water temperatures, which also causes oxygen swings. The fish we removed earlier this week were all forage type fish (primarily shad); unfortunately, these smaller fish - especially shad, minnows, reddear, etc. - are the most susceptible fish to any environmental changes.

I would like to be able to say, “Terry – this is what did it” with certainty. Unfortunately, taking all possible environmental variables and other non-environmental variables into consideration, it is extremely difficult to derive an absolute cause. But from our experience, the most likely contributing factor is the abrupt weather shift.

If you should have questions, or need additional information, feel free to contact me.

Obviously people don’t believe them since turtles died along with catfish not shad.
Anyone have suggestions? I wish I grabbed a sample and did an icp test but didn’t think of it until last night.

Anything we can do at this point? I don’t think stuff is passing any longer.

That's BS. We've had one fish kill in our lakes and that was because of the freeze. They poisoned them.

Agreed, I think it's just a "cover my ass" message.

Although I don't know if it was them. Most of me thinks its the yard maintenance group as they come on Mondays and it was reported later that afternoon. I question if they were spraying pesticide and too much got into the water for it to handle it.

Still frustrating to see such a "cover my ass" message from the company.
