COMPTUEX/JTFEX EA/OEA Final Chapter 4Pantropical Spotted Dolphin (Stenella attenuata)The pantropical spotted dolphin is not listed as endangered under the ESA, and is not considered to be astrategic stock under the MMPA. There are no abundance estimates available for this species in theNOAA stock assessment reports for this area of the Pacific. The modeling efforts and harassmentanalysis for mid-frequency active sonar estimate that no Level A harassment of pantropical spotteddolphins would occur. The analysis estimates that up to 547 incidents of non-injurious behavioralharassment (Level B harassment) may be experienced by pantropical spotted dolphins on annual basis(Table 4.3-23). Six pantropical spotted dolphins could be exposed to impulsive noises or pressures fromunderwater detonations that could cause TTS but would not cause physical injury.Table 4.3-23.
