“…Environmental factors such as temperature and salinity affect the health and productivity of shellfish populations directly by affecting processes such as filtration rate, respiration, and reproduction, and indirectly by affecting the abundance and feeding rate of predators and the dynamics of disease (Kim et al 1999). Disease can inhibit growth, lower the condition index, disrupt filtering activities, reduce the reproductive capacity, inhibit larval development, and reduce spatfall (O'Beirn et al 1994, Ford & Tripp 1996, Paynter 1996.…”

Oysters Crassostrea virginica are 'keystone' estuarine species in the southeastern USA, providing essential fish habitat, food for human consumption, filtration of water bodies, and protection against shoreline erosion. Relatively few oyster pathology studies have been conducted in Georgia. The parasitic protozoan Perkinsus marinus was first observed here in the 1960s, but has not been investigated since the late 1990s, when increasing oyster infection levels were apparent. In the late 1990s and early 2000s, the region suffered a prolonged drought, resulting in elevated salinities and the proliferation of various diseases in the marine environment. By 2003, salinities had returned to normal levels, but the effect of the drought on oysters was unknown. In June 2003, oyster reefs throughout Chatham County were sampled to evaluate the prevalence and intensity of P. marinus. The disease appears to have remained prevalent in the coastal waters of Georgia (100% prevalence at some sites), but the intensity was low, ranging from 0 to 1.83 on a scale where heavy infections rated a score of 5. While the disease did not occur at levels high enough to cause oyster mortalities, further monitoring, particularly on a temporal scale, is warranted.

“…Likewise, changes in the abundance of a dominant zooplankton species (Calanus finmarchicus) were related to large-scale freshening in the Gulf of Maine, as well as to changes in fish community structure (Pershing et al 2005). While no such indirect prey effects have been uncovered for the northern GOM, 3 studies in northern GOM estuaries have documented a salinity-moderated teleconnection between ENSO and the common oyster pathogen Perkinsus marinus that has large-scale indirect effect on oyster populations through regulation of growth and fitness (Kim & Powell 1998, Soniat et al 2005). …”

“…Northern Gulf of Mexico (GOM) estuaries support 66% of the US harvest of penaeid shrimps (Farfantepenaeus aztecus, F. duorarum, Litopenaeus setiferus) and 25% of the US harvest of blue crabs Callinectes sapidus (Zimmerman et al 2000). While many studies in the region have linked these species to environmental forcing conditions (salinity, water temperature, water level; Zimmerman et al 2000, Haas et al 2001, Roth et al 2008, few have linked that environmental forcing to large-scale climate processes (but see Childers et al 1990, Kim & Powell 1998, Soniat et al 2005. Given the importance of the GOM to US fisheries and the projected climatic effects on estuarine conditions (e.g.…”

Climate creates environmental constraints (filters) that affect the abundance and distribution of species. In estuaries, these constraints often result from variability in water flow properties and environmental conditions (i.e. water flow, salinity, water temperature) and can have significant effects on the abundance and distribution of commercially important nekton species. We investigated links between large-scale climate variability and juvenile brown shrimp Farfantepenaeus aztecus abundance in Breton Sound estuary, Louisiana (USA). Our goals were to (1) determine if a teleconnection exists between local juvenile brown shrimp abundance and the El Niño Southern Oscillation (ENSO) and (2) relate that linkage to environmental constraints that may affect juvenile brown shrimp recruitment to, and survival in, the estuary. Our results identified a teleconnection between winter ENSO conditions and juvenile brown shrimp abundance in Breton Sound estuary the following spring. The physical connection results from the impact of ENSO on winter weather conditions in Breton Sound (air pressure, temperature, and precipitation). Juvenile brown shrimp abundance effects lagged ENSO by 3 mo: lower than average abundances of juvenile brown shrimp were caught in springs following winter El Niño events, and higher than average abundances of brown shrimp were caught in springs following La Niña winters. Salinity was the dominant ENSO-forced environmental filter for juvenile brown shrimp. Spring salinity was cumulatively forced by winter river discharge, winter wind forcing, and spring precipitation. Thus, predicting brown shrimp abundance requires incorporating climate variability into models.

“…Several bodies of work have correlated a regime of climate factors (temperature and rainfall) to the fluctuation in contaminant loading in coastal environments. For instance, work by Kim et al (1999) has demonstrated the influence of climate on the temporal variability of contaminant body burdens in oysters from the GOM. Using NOAA Mussel Watch data, these authors were able to relate interannual variability in oyster tissue concentrations to El-Niño/Southern Oscillation (ENSO) events, which is in turn related to temperature, rainfall, and river runoff.…”

This study evaluated changes in oyster tissue contaminant levels following North Atlantic tropical cyclones to determine if changes in contaminant concentrations were predictable. The basis for this study was analysis of coastal chemical contaminant data from the National Oceanic and Atmospheric Administration's (NOAA) National Status and Trends Mussel Watch Program and NOAA's National Weather Service storm track data. The tendency for contaminant (metals and organic compounds) body burdens to increase or decrease in oyster tissue after a storm was assessed using contingency and correspondence analyses. Post-storm contaminant levels in oysters revealed a consistent pattern of distribution, which could be described as follows: (1) most of the organic contaminants stay within their long-term concentration ranges, (2) very few organic contaminants decreased, and (3) metals overwhelmingly tend to increase.
