There are no experimental studies available for this endpoint with diisobutyl phthalate, however there is a study available on the close structural analogue dibutyl phthalate which provide a suitable read across. 

Rhodes (1995) reports a 99 -day flow through test with Orconrhychus myskiss. The most sensitive endpoint measured is growth, for which the NOEC is 0.10 mg dibutyl phthalate/L.
