Alternate Title

Studies on the Toxicity of Mirex to the Estuarine Grass Shrimp, Palaemonetes pugio

Document Type

Article

Abstract

Estuarine grass shrimp (Palaemonetes) are common along the Gulf and Atlantic coasts (Faxon 1879, Gunter 1950, Williams 1965, Fleming 1967). These small decapods are found ranging through freshwater areas, brackish estuaries and into inshore saline waters where they are occasionally the predominant animal (Gunter 1950).

In view of the trophic significance of these shrimp, static system bioassays were made to determine the sensitivity of Palaemonetes pugio to Mirex in water and to 0.15% Mirex bait granules, since the USDA is continuing the fire ant control program but has plans in the future to substitute 0.15% Mirex bait for the 0.3% bait presently in use (J. I. Lowe 1972, personal communication).
