Here is a quick peek at the latest Florida strain Largemouth Bass being held at Bubbling Ponds Hatchery. These fish arrived from Florida several months ago and are averaging about 5-inches. They are trained to eat commercial feeds which will be critical in moving forward with our brood stock development. The goal is to have millions of Florida strain bass available for stocking from Arizona hatcheries in the near future.
If you’re wondering about how the Arizona Game and Fish Department project of stocking Florida-strain largemouth bass into Roosevelt Lake is going, well, it is far too early to make any conclusions. That said, early indications give a shred of hope for a robust population of catchable (8-10-inch bass) by next fall, and, in 4-5 years, the hope that trophy bass will be available at this rejuvenating fishery. These Florida-strain stockings, coupled with increased rainfall and an upcoming habitat improvement project, has the lake on its way back as a premier bass fishing lake in Arizona.
Time to geek out with some data.
Results from October 2015 Game and Fish surveys at Roosevelt Lake show spikes in populations from two distinct size classes.
The two far-left spikes of blue lines represent October 2015 results from 5.7 hours of electrofishing, compared to similar fall surveys in 2013 (red lines) and 2011 (green). All the rows measure frequency, or percent, of the total bass catch as they relate to size in inches.
This first row of blue lines (lengths of 2- to 3 1/2 inches) also indicated a healthy population of 5-6 month old largemouth bass, which possibly were boosted by spring 2015 stockings of
Florida-strain largemouth bass fry.
The next, highest row of spikes (6- to 8-inch bass) represents 1 1/2-year-old bass, possibly aided by stockings of Florida-strain fingerlings from this past spring, and/or the spring 2014 stockings of fry.
Note the green lines representing 2011 surveys and red lines from 2013 surveys showing a significant drop in frequency of young bass.
Again, this was only one survey, and at least two more surveys will be needed to make reliable conclusions.
OK, geek-out session over.
What we mean is: the “Rebound at Rosy” seems to be in progress.
I spent the morning at the AZGFD's Mesa office helping construct concrete habitat ball's that will soon be placed in one of our warm water reservoirs. The AZGFD has quite a simple assembly system in place, about 15 people assemble the molds on Tuesday, the concrete gets poured, another team comes in on Thursday to disassemble the forms and stage the balls for future use. Authorization to place the habitats in our lakes is still a couple of months away, awaiting authorization from the various federal government agencies who claim some form of jurisdiction over this project, but once these approvals are acquired, the AZGFD will have a green light to place habitat in all of our desert lakes. I also met Amberlea Jones, who is the Habitat Specialist with the AZGFD. Youthful and full of energy, Amberlea, along with the rest of the AZGFD, have a grand vision for our lakes to improve the catch rates in order to make fishing more fun for more people. Here is the schedule for the rest of the year, no experience required.
