Figure 3.
Whole-body lactate measurements (μg·g−1) in juvenile delta smelt during an acute and chronic predator cue exposure (NC = no cue; PC = predator cue) held at two temperatures (light grey = 17°C; dark grey = 21°C) and two turbidities (1–2 NTU & 10–11 NTU). Fish were sampled 15 min after exposure to a largemouth bass predator cue (vertical angled bars) or tank water (blank bars). Lactate levels were significantly greater in fish held in turbid conditions and during the chronic predator stress. Data (n = 14–20) are presented as mean ± SEM.
