TL;DR: Turbidity has both positive and negative effects on prey detection, by increasing or diminishing the contrast between prey and background due to the scattering of light, and might have a structuring effect on a fish community.

TL;DR: The reaction distance of Gobiusculus flavescens to mobile and immobile copepod prey of different transparency was studied in water conditions with different turbidity levels or spectral composition.

TL;DR: Current research on different communication systems (visual, chemical, acoustic, electric) and the state of knowledge of how complex systems respond to environmental stressors using fish as a model are discussed and an urgent need for a better understanding of the evolutionary consequences of changes in communication systems on fish diversity is seen.

TL;DR: Although gammarids were consumed more often and more quickly than mysids, both among tutors and naive fish, social learning from tutors demonstrating mysid hunting and consumption had its greatest effect on social learning in the enriched fish.

TL;DR: It is suggested that both predator attack speed and turbidity have important roles in determining the vulnerability of fish attacked by piscivorous predators.
