I will dig out the info and post.

In the meantime here is a bit to think about.

In the first year (and subsequent years also) warming spring/summer water temperatures ramp up metabolism and the need for food (feeding) and with it increased growth. An example is the information contained in Growth Rates and Temperature Selection of Bluegill, Lepomis macrochirus by Thomas L. Berttinger and John J. Magnuson in Transactions of the American Fisheries Society 108:378-382, 1979 which provides growth and temperature information for Bluegill. Interestingly maximum feeding and growth occur at different water temperatures. Bluegill feeding rates were best at 77 to 82 F and food conversion efficiencies at 83 F. High growth occurred over a broad range from 68 to 93 F (a few degrees below the upper lethal of 96 to 99 F). However, there was a difference between water temperatures at which highest growth occurred (86 to 88F) and maximum feeding (77 to 82 F).

The Effect of Largemouth Bass Predation on

Abstract.—Overwinter mortality is an important force structuring year-class strength of many fishes.
Conventional wisdom is that overwinter mortality is primarily caused by starvation; however, recent research
has demonstrated that piscivores continue to feed during winter and may also contribute to overwinter
mortality of their prey populations. We conducted experiments in ten 0.04-ha earthen ponds in central Illinois
to assess the effect of predation by largemouth bass Micropterus salmoides on survival of two size-classes
(20–30 and 40–65 mm total length [TL]) of age-0 bluegills Lepomis macrochirus. Bluegills (400 fish/sizeclass)
were stocked into each pond at the end of November. Half of the ponds also received five small
(90–124 mm TL) and four large (166–192 mm TL) largemouth bass. Survival to the end of the 113-d
experiment was higher for large bluegills than for small bluegills in all ponds. For both bluegill size-classes,
the predator-present treatment had higher mortality than the predator-free treatment. Relative to the predatorfree
treatment, mortality of bluegills in the predator-present treatment increased by 16% for the large sizeclass
and 49% for the small size-class. Mean length and relative condition (Kn) of both bluegill size-classes
increased by the end of the experiment in both treatments, suggesting that the observed mortality was not
caused by starvation. Further exploration is needed to elucidate why bluegills in the predator-free treatment
suffered overwinter mortality despite the increase in Kn during the experiment. Length and Kn of largemouth
bass increased (large size-class) or stayed the same (small size-class), suggesting that at least some of the
predators foraged during winter. Our results indicate that size-specific overwinter mortality of bluegills occurs
at the middle latitudes of the species’ range. Further, winter predation can be an important component
influencing size-specific overwinter survival and size-structured interactions between fishes.
