Data for: McCormick MI, Allan BJM, Harding HR, Simpson SD (2018) Boat noise impacts risk assessment in a coral reef fish but effects depend on engine type. Scientific Reports.

Key:

Examination of the impact of 2-stroke & 4-stroke 30hp Suzuki boat engine sound on the behaviour and space use of Pomacentrus wardi light trap caught recruits.

• 3 min behavioural observations. Fish caught in light trap, kept overnight and placed on Pocillopora patch reefs that were a combinatuion of live and dead (50:50).
• Fish were given 10 min to acclimate without boat noise. 2 x 3 design with 2 sounds (ambient and boat) and 3 cues (SW, Hetero= Apogonid, CAC). 
• 60 mls Cues released from a 1.5m tube; CAC made from the sides of one juvenile fish. Boat travelling 30 to 80 m from sites in a figure-8 loop. Depth 2-3m 

Location: Casuarina Beach, Lizard island

Startle response: Cassuarina beach in same spot. Using 80ml jars on startle frame. 120fps with GoPro.
