Population Genetics Analysis of the Grass Shrimp Palaemonetes Pugio Using Single Strand Conformation Polymorphism
… about the genetic structure of grass shrimp, Palaemonetes pugio, populations or the effects the parasite Microphallus turgidus has on it. The objective of this study was to determine the amount of genetic diversity of the shrimp populations based on locality and parasite load. In order to …

The Toxicity of Ammonia to Atlantic Silverside (Menidia menidia) and Ghost Shrimp (Palaemonetes pugio)
… and one marine invertebrate, ghost shrimp (Palaemonetes pugio), were tested in acute and 7-day chronic tests. The acute tests for the Atlantic silverside were performed at three levels of salinity in order to develop a better understanding of the relationship between ammonia toxicity and …

The lethal and sublethal effects of aldicarb on the estuarine grass shrimp, Palaemonetes pugio
… agricultural runoff. The estuarine grass shrimp, Palaemonetes pugio, has been shown to be a sensitive indicator of pesticide exposure. In this study, emphasis was placed on the quantification of the lethal and sublethal effects of aldicarb on three different life stages of P. pugio. Acute 96-h …

Effects of Ammonia, Salinity and Oxygen on the Growth and Energetics of the Grass Shrimp, <i>Palaemonetes pugio</i>
… and energy budget of juvenile grass shrimp,<em> Palaemonetes pugio</em>, were examined under various combinations of ammonia, salinity and dissolved oxygen. Experiments were performed to determine the effects of multiple stresses on the growth and physiological processes of the shrimp. The …

The toxicity of ammonia to the marine organisms, sheepshead minnow (Cyprinodon variegatus), mysid (Mysidopsis bahia), and grass shrimp (Palaemonetes pugio)
… the mysid (Mysidopsis bahia), and grass shrimp (Palaemonetes pugio). The acute LC 50 and the no-observed-effect-concentration (NOEC) were determined for each organism and compared to data in the literature. The species mean acute values (SMA V) for the sheepshead minnow (13.5% difference) and the …

Effects of the Parasite <em>Microphallus turgidus</em> on the Predation, Swimming Endurance, and Activities of the Grass Shrimp <em>Palaemonetes pugio</em>
… of its intermediate host, the grass shrimp, <em>Palaemonetes</em> <em>pugio</em>. I hypothesized that the presence of a large quantity of encysted parasites (>30) alters both the activity and swimming ability of infected grass shrimp, and as such alters its susceptibility to predation to …

Behavioral Analysis of a Digenetic Trematode Cercaria (Microphallus Turgidus) in Relation to The Microhabitat of Grass Shrimp (Palaemonetes Spp.)
… host of this parasite is the grass shrimp Palaemonetes pugio. The behavior of trematode cercaria often reflects the habitat and behavior of the host species. The objective of my study was to examine the behavior of M. turgidus in relation to the microhabitat selection of the second …
