Food Growth Formula

  • We are currently upgrading MFK. thanks! -neo
Amen to that - less is more. I feed quality pellets and live red wiggler worms. I try to skip at least two days per week of feeding... And my fish are probably still overfed :)

Okay, so you feed pellets plus the protein and fat from the live worms. I definitely agree with you regarding skipping at least two days throughout the week and still probably being overfed. My intention was more of a growth influence and not necessarily long term health. :) Would you suggest live food for growth, and if so, what kind of live food? What is the most healthful live food with high protein for growth, or perhaps even longevity?

Earthworms by dry weight have something like 62% protein. The worms sold for the fishing market are cultured in disease free facilities and I believe they undergo inspections so they can't introduce any diseases to the wild (though I'm not 100% certain on this). Super cheap, and the live for a month in the fridge. Culturing your own is always the best bet though.

Thank you, I was not aware if the nutritional content, and I also did not know they could live for a month in the fridge. Are they lean or is feeding them worms frequently still not very healthy? I have not ever fed my fish earthworms before, are they in the pet stores or do you mean the kind a person might buy for going fishing?

I've done some reading of aquaculture studies of feeding earthworms, different species, forms (frozen, ground, etc.) and what I've read has been mixed to say the least. Some studies report excess fat in fish fed earthworms, others don't. Some report good growth, others don't. Percent of feed including earthworms was a factor in some studies, as in a limited percent ok, too much not so good.

Example-- rainbow trout study
The results on growth rate and feed utilization efficiency of fish fed diets containing high levels of whole frozen worms suggested an adverse effect of worm incorporation, probably due to dietary energy/protein imbalance.

I've read different opinions by hobbyists. Personally, I wouldn't feed live earthworms to my fish, some of them carry some nasty parasites. Other than that, my conclusion from what I've read is feeding them as a supplement or treat is one thing, but not a good idea as a staple or major part of their diet. Some of what I've read basically says results were not good at more than 25% of their diet.
 
I wouldn't feed one live food to any animal for an extended amount of time, so the above is good advice. I supplement with worms occasionally.
 
I've been feeding live red wigglers that I culture for years. They're much clean, safer, easier, less likely to spoil...and, of course, cheaper than buying live blackworms.

The staple for my fish is quality pellets. I feed live worms a couple of times per week max...they're great for conditioning for spawning. Too much of anything will make you fish fat!
