Well fed yellow perch at 2 months will range from most at 1"-1.3" to a few fastest growers at close to 2". FYI some of your YP from last year could now be after 14 months 6"-8". Smaller ones then would be mostly males and slower growers.

Bill D. I did some looking for your requested info. There is info but it varies so much that its hard to give a cogent answer. Location , fertility ,type of plankton , other fish present , time of year/year class ,and others make a huge difference with YP. Most info is on YP at age 3+ and not on yoy/daily/monthly etc over year 1 and 2. Even the energetics models are different over time.

ewest, could you please provide the link to expected sizes for 3+ yr old YP. Mine have been in the pond a little over two years, and were mostly in the 2-4" range when stocked. It seems like they are pretty much the same size as last year. (Had very good growth the first 12 months). I'm thinking that maybe I'm looking at YP that are as big as they are going to get..
Sorry about the thread hijack..
thanks
Jeff


9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.

Thanks ewest! Good article. Looks like my YP are about average. Good to know. 3-4 years of age to reach harvest size.. Must mean my supplemental feeding is helping. I've harvested well over 100 so far, almost all have had fish feed present when cleaning.
Looks like they will continue to get a little bigger, but not a whole lot.
Thanks again.

SG,

I don't know if this input is of value to you but, I stocked 5 to 7 inch YP (most closer to 5) fall of 2015. The average I catch today are 9 to 10. I haven't stocked any pellet trained fish of any species but I do feed pellets and do get fish coming to feed every night. Although I haven't caught any, the bigger YP look to be 12 or so.

Bill, I think that's about where mine are in length. I stocked my YP in the spring of 15, and have had the feeder running most of the time. I need to get a ruler down at the pond to get actual length measurements. I'll do that today, as we will be catching some more. Last night the 2 yr old twins (grandkids) were catching fish faster than I could bait hooks, and put the fish in the basket. Caught mostly HBG, but did manage to bring in six YP. I'd say they were all 8-9".
I've got to admit, the HBG have grown to twice the weight of the YP, and put up three times the fight, but the YP are easier to clean at 9:00 at night, and taste the best. If my HBG weren't half piranha, I'd be a bit happier with them. wink

Caught several more yesterday. Maybe it was juggling the 2 yr old twins, my daughter, my mother in law, and my crazy Drathaar. I didn't measure a single one. My water temps are still pretty cool, so the YP are still hitting.
