WOW!!

That's Photoshopped! The guy was obviously playing a guitar in the original photo.

I'm trying to figure out what is on his pants though.

It's the real deal. Probably a triploid.

Are we talking triploidy from a lab, or from some chance occurence?

In some bass tournaments that fish would be disallowed. It's hooked on the outside of the mouth.

That, and the fact that it's not a bass.

Are you sure? To me it looks like the treble hook comes out behind the mandible from the inside.

Sasketchewan plants triploid trout. Both rainbows and brooks that I know of. A lot of people don't know it, but triploid trout are not that uncommon in some places. Most trout farms these days have given up keeping broodstock on hand and going through the labor and expense of producing their own trout. Many order triploid or sterile female eggs from places like Trout Lodge in Washington state. My state of Indiana is experimenting with ordering eggs to cut costs for their inland rainbow trout program. I have read all coho and chinooks in Canada raised for food market are triploids.

Here's a link to trout lodge:

Cecil, where do small pond owners get rainbow trout to put in their ponds? and still cant cross state lines with them?

Who says you can't cross state lines with them? You can as long as they follow your states disease testing protocols. That is, unless Iowa has prohibited interstate transport of trout. The Feds did do this last fall and early spring but only temporarily.

You need to find an intrastate source or interstate source that delivers. Usually state fish & wildlife angencies have a list of suppliers.

CB1 knows lots of stuff.

Bruce is the bluegill man though!

WOW!
For the life of me I can't understand how a fish that lives maybe 5,6 or 7 years can get that big. Even as a triploid and living maybe 10 years..........thats 4.36 lbs. of weight gain average per year!

Cecil, what is average lifespan of triploid rainbow?

Theo, That was hilarious!

Ed,

I replied to this but for some reason it disappeared!

Anyway, here's my take on this. For one thing fish are like people. We have an average life expectancy but there are some of us that don't make it that long and there are others that far exceed that. But one difference with fish and us as you probably know is fish don't stop growing completely (at least most of their life span) Growth will usually slow down but the fish still keeps growing if it remains healthy.

I understand some rainbows live up to 11 years especially in hard water. But it may not necessarily be that old. Our state record largemouth bass of about 14 lbs. + was no older than a typical 6 or 7 pounder. Sometimes individual fish just grow really fast. They are freaks or anomolies. Add to that this fish obviously had a very good forage base as is evidenced by it's robust body shape. In fact, it's a fast growing fish as is evidenced by its large body for the size of the head, and most of it's weight is in its girth. If it is also a triploid, it was not putting any energy into gonadal development, and was not stressed by spawning activities, which usually include periods of not eating. In other words everything came into place to make this an exceptional fish.

Note: Maybe my previous post didn't disapear as it was there once I posted again! Whatever!

Cecil,

I did read your first post about rainbows achieving huge weights for varied reasons.
I guess for any animal to grow to its maximum potential it needs three things:
1. Age
2. Nutrition
3. Genetics

I believe many of us pond-meisters can satisfy the Nutrition part of this tri-ad. Its getting over the Age and Genetics hurdle that stumps most of us.
Condello and others are pushing the envelope on genetics (BG, RES and YP), which is interesting and fascinating to me.

Now, if we could just jump the Age barrier and produce fish that consistently that live longer than their counterparts. This is probably already being done to a certain degree with triploids, sterile females and X-breeds.

Also there needs to be a market for huge fish of a certain species.
Example: The fish rearing facility where I buy my rainbows (Buffalo Gap, SD) have absolutely no need or desire to produce fish that live longer. Their rationale is: Most of their fish go to Canada, are grown to two years of age, then butchered and sold as meat.

This is interesting stuff.

Ed

Ed,

You can get fish to live longer by growing them in colder water and/or breeding fish that live longer. Granted they won't grow as fast in colder water but sometimes they will at least be as large as a fish that grew faster in warmer water and died early.

Case in point: The Seeforellen browns come from colder water than the Great Lakes where they are planted. Even though some of them were reaching large size, the concern was they would die before they reached world record potential due to the relatively warmer water.

I'm finding that even this part can be tricky. It turns out that my bluegill that are fed copious amounts of pellets don't grow as large as the fish that have the option between pellets and abundant natural forage. The growth curve in one of my smaller ponds has flattened out a little because I have too high a density of YP, which are vacuuming up all the invertebrates. I'm working on this.

Any thoughts, theories, speculations as to why this is true Bruce? Seems counter-intuitive. (dang is that a fancy phrase or what).

I think that pellets provide lots of calories, but not neccesarily the optimal variety of nutrients for creating the uber-fish.

My best fish come from a pond with tons of various, easy to catch invertebrates, and lots of pellets, too.

The perfect home for "Mr. Opportunity" (copyright, Bruce Condello) who eats everything.

Additonally we are feeding pellets that have been designed for trout or at lower protein levels for catfish or talapia. There is no pellet feed that has been specifically designed for bluegills or even yellow perch or largemouth bass for that matter. One problem is fish that are fed entirely on pellets get too many carbs which causes them to be obese and functional diabetics. This may also shorten their lifespans. This is expecially pronounced in largemouth bass which also do not as of yet, have a feed that is specifically forumlated for them. However the new large pellets produced by Aquamax for largemouth bass do have lower carbs and are supposed to emulate the components of a rainbow trout. My bass love them. I may experiment with busting them up for my other fish if the carbs are lower.
