Marine Science

Experimental results reported herein were obtained on colonies of serpulid worms collected from a filter box (Fig. 1) through which water was pumped at a rate of about 1,000 gallons per day. The filter box was located within and the water was drawn from the cooling water intake system of the Central Power and Light Company plant located between the Port of Corpus Christi and Nueces Bay, Texas. Although at least three species of serpulids were identified from this locality during the spring of 1969, all specimens collected for experimentation included only Hydroides norvegica. Salinity of the water in the Port of Corpus Christi ranged from 29 to 35 ppt through the sampling period.
