Figure 4.

Protein-to-mass ratios (μg·mL⁻¹·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). Protein-to-mass ratios were significantly greater in fish held at 17°C compared with those held at 21°C. Data (n = 15–20) are presented as mean ± SEM.
