Necropsies of Cedar Bass - Bad News

Today I sampled 11 bass from Cedar.  All were 16-30 cm long.  I performed necropsies on all of them and found Clinostonum in all but one bass.  They all (but 1) had quite a few of the parasites in them.  Bigger fish had more parasites than smaller fish.  Clinostonum is commonly refered to as "yellow grub".  This may well be the reason Cedar is on the decline. 

Time to take action!

Carrier Fish eating birds defecating in the water releasing the eggs...which take up host in snail until the reach their larval stage and seek out a fishy host, which gets eaten by the birds and so on and so on.... The amount of biomass in the AV lakes makes it more succeptable to an outbreak

In the aquarium trade we dose Praziquantel but it is very expensive even in small quantities, I wouldnt know where to begin on a body of water as large at cedar...

Re: Necropsies of Cedar Bass - Bad News

I started to do a little bit of research on this-

Read this on the Iowa DNR website(http://www.iowadnr.gov/fish/programs/farmpond/fpp.html):

"It is not practical to try to remove these parasites from a pond. Pond owners and fishermen must be resigned to the fact that occasionally they are going to catch a fish containing one of these parasites. "

I hope they are wrong.

Also some more information about clinostomum on this website:
http://dnr.wi.gov/fish/health/clinostomum.html


If we figure out a cure, I'd be happy to help out.

You have to get rid of the snails or the herons.  Crayfish will be the best bet.  They eat snails and multiply greatly.  Fish also like crayfish.  We need the L&P Committee to forward a proposal to the BoD to take care of this.

See previous post about a month ago:

Any particular type of crayfish? Hopefully something that is native to VA.
