在雷诺数为41，000 ± 14，000时，蓝鳃太阳鱼Lepomis macrochirus的阻力系数由滑行减速估算为（平均值± SD）0.0154 ± 0.0070。这是在其他物种的滑行范围内，低于该物种和其他物种的死阻力测量值。滑行期间的低动量损失可以允许其在间歇推进期间使用以调节功率输出或最大化能量经济性。
The drag coefficient bluegill sunfishLepomis macrochiruswas estimated from coasting deceleration as (mean ± SD) 0.0154 ± 0.0070 at a Reynolds number of 41,000 ± 14,000. This was within the coasting range in other species and lower than values obtained from dead drag measurements in this species and others. Low momentum losses during coasting may allow its use during intermittent propulsion to modulate power output or maximize energy economy.
