- “Midsummer” was defined as 28 July through 7 September, when fish were resident on shallow grounds. “D-1” represents mean temperature during the week prior to the fishes’ departure to deep water; D-2 is the week prior to D-1, and so forth. The superscripts after the midsummer means indicate two groups determined to be significantly different (p < 0.05) from one another. In no region were mean temperatures experienced during the 4 weeks prior to departure found to be significantly different from the region’s midsummer temperature
