Koi and the Blob

September 10th, 2007

    A productive weekend even with rain.  It’s so nice to have softer soil to work with after the dry summer months.  It was time to plant/transplant a few shrubs, clean up wood debris and cut the grass.  The air is noticeably cooler and the grass is turning green once again.  I wish the days were still longer to get more done, but I really enjoy the afternoon light with the sun lower in the sky.  It makes for shadows and dappled light throughout the property, and relaxing evenings.   I spent some time walking the pond this weekend also.   And lo and behold, I finally saw the little Koi we released a couple weeks ago.  They were meeting the bigger Koi near the dam at the time.  I didn’t get too close, but noted the two little Koi swimming near the side of a larger Koi.  I’m just glad they haven’t been eaten!  Later I came back for a few pictures.

     Here are two of the big Koi, and they are very large, probably 15-20 pounds… that’s a Maple tree leaf floating near the orange one’s mouth!  When I stocked them last year, they were only 10 inches- not even half of their present size.  We don’t feed them, but they are obviously doing just fine.

     And here is a shot of the little Koi we just stocked- it’s only about 7 inches long… can you see the Largemouth Bass to the left?   That’s about a 12 inch Bass.  The Koi was swimming along with the Bass for some reason, but it’s a quick one- when it saw me on the bank it darted off in a hurry.  It will be a beautiful Koi when it grows up.

I came across this “blob” near the shoreline the other day.  In the Spring I would think it was a mass of frog eggs, but after careful inspection it’s a mass of Bryozoans.  They are a gelatinous group of tiny colonial organisms, sometimes called Moss Animals.  Most species of Bryozoa live in the ocean with harder structures much like coral, but there are a few that live in freshwater lakes, pond and rivers and are more gelatinous.  They are supposed to be a positive indicator of good water quality,  because they feed by filtering microscopic protozoa and algae from the water.  But that’s mostly in terms of  water quality affected by mud or silt perhaps.  I read that some of these Bryozoan masses can move on their own by the swimming action of the tiny colonial organisms!

  1. Now I know what that blog in my pond was a few years back.

    Good looking koi.

  2. Hi Pablo! They are pretty… I just enjoy watching them at different places, I never know where they’ll show up.

  3. I meant “blob” not “blog.”

  4. Sometimes I feel like my blog IS in the pond! :)

    I stumbled upon this blob in my pond 3 days ago and have been searching google to find what it was and I ran across your blog. I thought it may have been frog eggs myself but, it is much too big for that. The little one has been poking at it with a stick for the past two days. Thank you for your rather informational blog.

    Y’know, reading about bryozoans is cool and all, but I think if one of the mobile ones blundered into me in dark lake water I think I would crap my pants.
