Segregation Of Palaemonid Shrimp Along The Shark River Estuary: Implications For Trophic Function, Lauren C. Mccarthy
Segregation Of Palaemonid Shrimp Along The Shark River Estuary: Implications For Trophic Function, Lauren C. Mccarthy
HCNSO Student Theses and Dissertations
This study examined the abundance, distribution, and spatiotemporal variation of palaemonid shrimp species in relation to season and salinity in the Shark River Estuary, Everglades National Park (ENP), Florida, USA. Five palaemonid species occurred in the samples: Palaemonetes paludosus, P. pugio, P. intermedius, Palaemon floridanus, and Leander paulensis; L. paulensis was collected only during the wet season. Overall, shrimp catches in traps doubled in the dry season. Catches in the upper estuary were dominated by P. paludosus, particularly in the wet season, while catch per unit effort (CPUE) at the most downstream, …
Temperature And Salinity Tolerance Of The Larvae Of The Sand Shrimp, Crangon Septemspinosa (Say), Karen Lyttle Hinsman
Temperature And Salinity Tolerance Of The Larvae Of The Sand Shrimp, Crangon Septemspinosa (Say), Karen Lyttle Hinsman
OES Theses and Dissertations
The effects of temperature and salinity on the larval development of the sand shrimp, Crangon septemspinosa, were investigated in the laboratory using 30 combinations of temperature and salinity in a five by six factorial experiment. The five temperatures were 5°c, 10°c, 15°c, 20°c, and 25°c and the six salinities were 10°/oo, 15°/oo, 20°/oo, 25°/oo, 30°/oo and 35°/oo. Thirty-six larvae were used for each temperature-salinity combination. Temperature and salinity produced significant differences (1% level) in survival and the duration of larval development. Highest survival occurred at 15°c and 20°/oo. At optimum temperatures (15°c to 20°c) larvae exhibited the broadest tolerance …
