A survey was conducted to identify the macrofauna of a marsh adjacent to West Galveston Bay, Texas. The factors affecting its distribution were studied to help evaluate changes which might result where large areas of the marsh are impounded for shrimp culture. It is concluded that large-scale impoundments would alter the physical features of the marsh and significantly reduce habitat suitable for year-round survival of the stable microfauna. Competitior and predator control in these ponds would require the removal of all aquatic macrofauna other than shrimp. Conceivably, marsh areas could be managed so as to insure a reasonable amount of habitat for stable macrofauna while allowing ample land for shrimp culture.
