Behavioral mechanisms can play an important role in controlling distribution at all life stages and survival during early life stages, when mortality rates are high and variable. Under controlled laboratory conditions, behavioral responses are examined under various extrinsic physical (e.g., light, temperature, chemical gradients, and turbidity) and biological influences (e.g., prey distribution and density, social interactions, and predation), and intrinsic factors such as hunger, condition, and stress. A major goal of the research is to understand how these various factors are integrated into behavioral decisions or trade-offs by fish encountering different environmental conditions. Results are evaluated in conjunction with field studies to improve sampling surveys, to model responses by fish to environmental changes and, ultimately, to aid in predicting both survival and recruitment potential.
