Probably beats the old record by a couple pounds... Don't know anything about Lake Havasu, I wonder what the characteristics of it that made it able to produce such a massive RES?
I hear that the lake contains a large population of asiatic shellfish, one report stated they were quagga mussels, another claimed the more common zebra mussel. Whatever the case, apparently RES find them delicious!
Yes, the old record was 5 pounds, 5.5 ounces. The new record listed as 5.55 pounds would be 5 pounds, 8.8 ounces. So roughly 3 ounces more than the previous record. It seems to grow GIANT RES, a steady supply of tasty shellfish in needed...
Sprkplg is right - it's generally being accepted that invasive bivalve introduction to Havasu are responsible for the accelerated growth. I also read that Drum and Blue cats love Zebra and Quaggas. While it's negative impact on the ecosystem is well founded, at least there's some benefit from introduction of these mussels - we could be seeing some huge fish coming down the pike. I don't think 5.5 lbs is the top range for RES with that much available forage protein with little to no effort expend energy to stalk and ambush. A RES could literally sit on a reef of these things and not move more than a fin all day. Sounds appealing, actually!
I also read where the specific area of the lake where this fish was caught had undergone treatment for excessive weed growth. Some folks are claiming that the nearly bare lake bottom in that spot had made for some easy pickins' for the RES. I heard there have been other large specimens taken there recently.
Of course, a redear of that magnitude probably wouldn't have obtained that size in just a year or two's foraging, no matter how few weeds were present.
The previous world record was caught in an area that had recently been invaded by Asiatic clams. Certainly seems non native molluscs are key to growing record size RES. Before anyone gets any ideas of stocking any of these species, research the risks closely... The idea of stocking Asiatic clams on here has been talked about in the past in previous threads.
It actually looks like a BG X RES hybrid to me. I have a lot of those hybrids in my pond and they all have that "brown" edge on the gill flap like the one in the picture. The pure RES always have a red or orange edge.
If you guys would like to hear Robert Lawler describe his catch, check out Fish Schtick podcast. Listened to it yesterday and it's great hearing a fish story from the fisherman himself. Very well described.
