Tests of 14‐ to 16‐days duration were conducted to determine the distribution and sublethal effects of mirex in an experimental estuarine ecosystem. The insecticide was translocated from water at concentrations of 0.011 to 0.13 μg/liter to sand, plant, and animal components. An alteration of predator‐prey interaction due to mirex was manifested by a significant difference (X 2 test, α = 0.05) in survival of grass shrimp, Palaemonetes vulgaris, in control and treated tanks after one, two, or three days of predation by pinfish, Lagodon rhomboides.
