Title: Emigration of penaeid shrimp from the once-through cooling lake of Cedar Bayou Steam Electric Generating Station, Baytown, Texas

Abstract

Migration and distribution of two decapod shrimp, Penaeus setiferus and P. aztecus, in the cooling-water system of a power plant on the Texas coast were investigated, with emphasis on the seaward emigration from the cooling lake. Samples were collected every two weeks for a year by straining water leaving the lake over a drop structure, trawling in the cooling lake, and flushed from the intake screen. Shrimp catches at the drop structure were positively correlated with the standing population in the cooling lake. Significantly more shrimp passed over the drop structure nocturnally than diurnally. Shrimp caught at the drop structure diurnally averaged either smaller or similar in size to the shrimp taken there at night. The passage of a cold front enhanced migration and initially increased and then reduced the mean size of shrimp passing the drop structure. Higher percentages of the shrimp population in the cooling lake emigrated near new moon than full moon. The moon-phase effects appeared to be due to the moon cycle itself rather than to the intinsity of moon light. Significantly more shrimp of both species emigrated during the hours of ebbing than incoming tide. As the lake surface was above high tide level, anmore » endogenous timing mechanism rather than evironmental factors associated with tidal rhythms controlled this emigration pattern. A temperature drop of up to 0.23 C/hour significantly increased P. aztecus emigration.« less

  • White shrimp Penaeus setiferus, were grown in monoculture or in polyculture with blue shrimp P. stylirostris, or striped mullet Mugil cephalus in 0.1-ha earthen ponds receiving heated effluent from the Houston Lighting and Power Company's Cedar Bayou Generating Station east of Baytown, Texas during 1978 and 1979. No detrimental effect of either species on white shrimp survival or yield was found. Blue shrimp was greater than that of white shrimp in the same ponds. Total yield was increased by polyculture. An experiment was performed in which blue shrimp were stocked conventionally into ponds, or stocked in three successive increments (staggeredmore » stocking study). A preliminary experiment was made in 1978, followed by a more expanded version in 1979. Staggered stocking increased pond yields compared to expected values from the control pond yields. There was no detrimental effect of staggered stocking on shrimp survival. Pond salinities were much lower in 1979 than in 1978, associated with lower shrimp growth, survival and yield. A distribution study performed in the staggered stocking study ponds revealed that blue shrimp in mixed-size culture tend to segregate by size, and that small shrimp show somewhat different distribution patterns and temporal activity patterns than large shrimp. All the organisms used also served as biological monitors of water quality. No detectable levels of pesticides were found in any of the cultured animals. The only heavy metal found in higher concentrations than in previous years at this site was chromium.« less
  • Increasing water scarcity and a greater concern over the fate of the aquatic environment call for a new approach to designing cooling systems of large energy facilities that would result in a flexible demand for water and would enable better utilization of the environment as a heat sink. This work represents an attempt at demonstrating the desirability and feasibility of pursuing such an approach through the development of a hybrid cooling system consisting of a spray pond thermally coupled with two natural draft dry towers. Models for designing and simulating the operation of the system components were developed. A preliminarymore » design of the hybrid system is presented. The results of a limited simulation of the operation of the dry and evaporative cycles indicate potential environmental and operational advantages can be gained from a hybrid cooling system of this type. Energy and water conservation policy alternatives and associated operating rules were developed in light of the results obtained.« less
  • Background concentrations of Sr-90 in water, soil and milk samples collected from preselected locations around the first nuclear power plant in Texas, the Comanche Peak Steam Electric Station at Glen Rose, were measured in the period 1980-82. Statistical analyses of measured data showed that: 1) in the first approximation, Sr-90 is distributed uniformly in the North Central Texas area; 2) no seasonal variation is observed in the concentrations measured in water, soil and milk; 3) the Sr-90 content of surface water is shown, however, to be higher than that of underground water; this difference might be explained by the atmosphericmore » (fallout) origin of Sr-90 generated in atmospheric nuclear explosions before 1963; 4) in the area under investigation, Sr-90 concentrations turns out to be lower than those measured in northern parts of the US. This difference might be explained by the fact that the majority of atmospheric nuclear explosions were carried out at higher latitudes than that of Texas, and by the approximative conservation of latitude in the atmospheric motion of radioactive clouds.« less
  • The efficacy of the disposal of waste heat from steam-electric power generation by means of once-through cooling systems was examined in the context of the physical aspects of water quality standards and guidelines for thermal discharges. Typical thermal standards for each of the four classes of water bodies (rivers, lakes, estuaries, and coastal waters) were identified. The mixing and dilution characteristics of various discharge modes ranging from simple, shoreline surface discharges to long, submerged multiport diffusers were examined in terms of the results of prototype measurements, analytical model predictions, and physical model studies. General guidelines were produced that indicate, formore » a given plant capacity, a given type of receiving water body, and a given discharge mode, the likelihood that once-through cooling can be effected within the restrictions of typical thermal standards. In general, it was found that shoreline surface discharges would not be adequate for large power plants (greater than or equal to 500 MW) at estuarine and marine coastal sites, would be marginally adequate at lake sites, and would be acceptable only at river sites with large currents and river discharges. Submerged multiport diffusers were found to provide the greatest likelihood of meeting thermal standards in all receiving water environments.« less
