Like Semen for Fish

The best acid test for a UM post is to see what websites I’m talking about to friends.  Last night I told at least 3 different groups of people about feeding semen to fish.  The forum starts off simple enough.

Is there any reason that semen would be bad for my fish?

well?

My favorite follow ups include:

Ha! No, not for them to swim in. I mean for eating. I have fed my guppies some of my sperm on several occasions, and they go absolutely nuts (no pun intended) over it. It’s so funny to watch.

But after posting that fact on a message board that I frequent (yahooka.com), some replied that it may be harmful to the fish. I don’t see any reason why it would. After all, in Mike Wickham’s “The Complete Idiot’s Guide to Freshwater Aquariums”, he says the the best fish food is variety.

I’d be worried that one morning there’s be a new fish in the tank with my face.

Semen itself has high concentrations of potassium, zinc, citric acid, fructose, phosphorylcholine, spermine, free amino acids, prostaglandins and enzymes, which nourish and protect the sperm…

Does any of that harm fishes?

Read it all at straight dope.
