“…The occurrence of hypoxia in coastal and estuarine environments, and the impacts of hypoxia on estuarine organisms, have been well documented in recent years (Wannamaker and Rice 2000;Bell and Eggleston 2005;Goodman and Campbell 2007;Thomas et al 2007;Stierhoff et al 2009). Coastal hypoxia generally occurs in warm months, and the duration of hypoxic events can vary from months, weeks or days to hours or minutes.…”

“…However, estuarine species often have a relatively high tolerance to hypoxia, although remaining in such sub-optimal conditions can result in decreased growth (Coiro et al 2000;McNatt and Rice 2004;Stierhoff et al 2006Stierhoff et al , 2009 and reproductive impairment (Thomas et al 2007;Landry et al 2007;Brouwer et al 2007;Brown-Peterson et al 2008). Furthermore, exposure to hypoxia can have profound physiological consequences on fish and invertebrates, such as alterations in systemic and molecular control mechanisms of oxygen transport (Cochran and Burnett 1996;Mangum 1997;Terwilliger 1998;McMahon 2001;Paul et al 2004).…”

Impacts of cyclic hypoxia on reproductive and gene expression patterns in the grass shrimp: field versus laboratory comparison

et al. 2010

Identification of organisms able to act as biological indicators of hypoxia exposure is important given the increasing frequency of hypoxic events worldwide. Grass shrimp, Palaemonetes pugio, are ubiquitous estuarine residents in the southeastern US, where they commonly experience cyclic hypoxia. We hypothesized that reproductive and gene expression patterns of grass shrimp in cyclic hypoxic field sites relative to normoxic sites would be similar to previous results from cyclic hypoxia laboratory experiments showing differential up-and downregulation of hypoxia-responsive genes. There were few differences in gene expression of indigenous shrimp collected during summer from two Gulf of Mexico estuarine systems [East Bay, FL (EB) and Weeks Bay, AL (WB)], although down-regulation of the gene coding for vitellogenin-1 corresponded with a decreased relative fecundity and fewer ovigerous females at cyclic hypoxic field sites, suggesting an overall impact on reproduction. The gene expression profiles of grass shrimp caged for 7 days in field sites differed by estuary, but few hypoxia-responsive genes identified in laboratory studies were differentially expressed in field shrimp. Overall, genes coding for protein synthesis, protein degradation, carbohydrate and lipid metabolism and electron transport were mostly up-regulated in EB caged shrimp but generally down-regulated in WB caged shrimp and laboratory shrimp. Thus, caged grass shrimp from different bay systems exhibited profoundly different gene expression profiles. Such profiles may serve as sensitive bioindicators of differences in water quality, habitat quality or food resources among estuaries but are not effective as indicators of hypoxia exposure.

“…Indeed the major energy allocation to osmoregulation causes a decrease in growth in the estuary of the Saloum (Panfili et al, 2006). Certain factors such as increased salinity may also induce a reduction in the growth of some estuarine species (Panfili et al, 2004;Stierhoff et al, 2009).…”

“…Scientific studies have found evidence that hypoxia can affect different fish species in various ways such growth and mortality (for example, Peterson et al, 2000;Miller et al, 2002;Stierhoff et al, 2009;Thomas et al, 2007). While the biological effects of hypoxia on marine species are relatively well studied, the body of work that focuses on the economic consequences of hypoxia is still quite limited.…”

Time series effects of dissolved oxygen and nitrogen on Long Island Sound lobster harvest

2016

Abstract:The formation of hypoxic water zones in marine ecosystems across the world is a growing concern among marine scientists and regulatory agencies that focus on marine resource management. In the United States, a number of water systems such as the Gulf of Mexico, Long Island Sound, and the Chesapeake Bay experience hypoxic conditions annually. Nutrient rich water with excessive nitrogen content is widely recognized as a key anthropogenic cause that lead to development of hypoxic zones. While the dissolved oxygen level indicates the presence of hypoxic water conditions, at any given time, the aquatic nitrogen concentration indicates the possibility of formation of hypoxic zones in future time periods. Hence, understanding the effects of both these variables on current and future fish population is important for improved water quality management and sustainability of marine resources. In this paper, we estimate the temporal effects of these two key variables on lobster harvest from three contiguous fishing zones in the Long Island Sound that vary in ambient water quality. We find there is no contemporaneous effect of these variables on harvest in both the zone that experience hypoxia and the two zone that do not. While there is some evidence of lagged effects of these variables on harvest, no systematic pattern emerges in these effects that distinguishes the hypoxic fishing zone with non-hypoxic zones.
