“…Impervious surface increases runoff volume and intensity in streams, leading to increased physical instability, erosion, sedimentation, thermal pollution, contaminant loads, and nutrients. Measurable adverse physical and chemical changes (increased salinity, upland erosion, increased sediment, increased chemical contaminants) were noted in tidal creek ecosystems in South Carolina when IS exceeded 10-20% (Holland et al, 2004). Arnold and Gibbons (1996) synthesizing studies conducted through the mid-90s indicated that stream health degradation first occurs at 10%, impacted health is observed between 10-30% and above 30% IS within a watershed there is degradation.…”

Iwanowicz, Luke R.; Minkkinen, Steven; Draugelis-Dale, Rassa O.; and Uphoff, James H., "Reproductive health of yellow perch Perca flavescens in selected tributaries of the Chesapeake Bay" (2013 H I G H L I G H T S► Reduced recruitment of yellow perch has occurred in urban tributaries of Chesapeake Bay. ► We compared reproductive health biomarkers in perch from two urban, one developing, two less developed watersheds. ► Lack of final maturation, abnormal yolk and zona pellucida were noted in females. ► Leydig cell proliferation was noted in males. Reduced recruitment of yellow perch has been noted for a number of years in certain urbanized watersheds (South and Severn Rivers) of the Chesapeake Bay. Other rapidly developing watersheds such as Mattawoman Creek are more recently showing evidence of reduced recruitment of anadromous fishes. In this study, we used a battery of biomarkers to better document the reproductive health of adult yellow perch collected during spring spawning in [2007][2008][2009]. Perch were collected in the South and Severn Rivers, Mattawoman Creek and the less developed Choptank and Allen's Fresh watersheds for comparison. Gonadosomatic indices, plasma reproductive hormone concentrations, plasma vitellogenin concentrations and gonad histology were evaluated in mature perch of both sexes. In addition, sperm quantity (cell counts) and quality (total and progressive motility, spermatogenic stage and DNA integrity), were measured in male perch. Many of these biomarkers varied annually and spatially, with some interesting statistical results and trends. Male perch from the Choptank and Allen's Fresh had generally higher sperm counts. In 2008 counts were significantly lower in the perch from the Severn when compared to other sites. The major microscopic gonadal abnormality in males was the proliferation of putative Leydig cells, observed in testes from Severn and less commonly, Mattawoman Creek perch. Observations that could significantly impact egg viability were an apparent lack of final maturation, abnormal yolk and thin, irregular zona pellucida. These were observed primarily in ovaries from Severn, South and less commonly Mattawoman Creek perch. The potential association of these observations with urbanization, impervious surface and chemical contaminants is discussed. a b s t r a c t a r t i c l e i n f oPublished by Elsevier B.V.

“…Hediste diversicolor). It can be suggested that fish caught these difficult ''substitution prey'' mainly because they occur at very high densities in salt marsh creeks (see Holland et al, 2004 for polychaetes' density calculations), representing the main food item for other young fish species (e.g. N. integer for stickleback : Søndergaard et al, 2000).…”

Does the invasive plant Elymus athericus modify fish diet in tidal salt marshes?

International audienceThe invasion of Mont-Saint-Michel Bay salt marshes (France) by a grass species (Elymus athericus) has led to important changes in vegetation cover, which is likely to modify the habitat for many invertebrates. Some of them constitute the main food items for several fish species, such as young sea bass (Dicentrarchus labrax) and sand goby (Pomatoschistus minutus), that feed in salt marsh creeks during high tides. As a result, fish nursery functions of salt marshes could be modified by the E. athericus invasion. In order to test this hypothesis, gut contents of the two most abundant fish species (sea bass and sand goby) were compared before and after E. athericus invasion in the same salt marsh creek and using the same methodology. The accessibility and availability of the main food item, the semi-terrestrial amphipod Orchestia gammarella, were estimated and compared between invaded (dominated by E. athericus) and original areas (dominated by Atriplex portulacoides). Gut content analysis showed a significantly greater percentage of fish leaving with empty guts from E. athericus areas than from A. portulacoides areas. The sea bass diet composition study showed a major shift in the relative importance of the main food items: before E. athericus invasion, diets were dominated by the semi-terrestrial species O. gammarella, whereas after the E. athericus invasion they were dominated by a marine mysid Neomysis integer. The same trend was found for sand gobies, with a shift of the main food item from O. gammarella before invasion to the polychaete Hediste diversicolor after invasion. These trophic changes may be explained by the lower accessibility and availability of O. gammarella in invaded communities than in natural ones. The E. athericus invasion, observed throughout northern Europe, is thus likely to disturb trophic function of natural salt marshes for fish. This preliminary study of the E. athericus invasion is also an illustration that invasive species are an urgent problem in conservation biology

“…Short-term fluctuations in physical conditions of the water column within flooded creeks generally exceed those in major channels and open waterways. Intertidal creeks closest to the uplands are most variable due to the influences of freshwater runoff and development within adjacent watersheds (Holland et al 2004).…”

Spatial variations in nekton use are often attributed to differences in the configuration and composition of habitat. We predicted that differences in nekton use among intertidal creeks were related to certain geomorphological characteristics. We measured or derived 28 features at 8 intertidal creeks in the high salinity North Inlet Estuary, South Carolina, USA. Nekton were collected simultaneously from all creeks once each season for 2 yr. Spatial variations in total abundance and biomass were greater than seasonal variations. Differences of 3-to 30-fold in resident and transient taxa densities occurred among creeks on the same date. Relative use (ranks) was similar among seasons and years. In canonical correlation analyses, depth, steepness, flow, and location were primary factors for total nekton and many taxa. Creeks that were shallow, broad, and filled and emptied slowly supported the greatest use. Total nekton use was not related to creek size, amount of edge, or oyster bottom. Grass shrimp Palaemonetes spp., numerically dominant in 83% of the collections, responded most to creek shape. Mummichog Fundulus heteroclitus favored shallow creeks with low flow and low proportions of submerged bottom at low tide. Juvenile spot Leiostomus xanthurus and pinfish Lagodon rhomboides were associated with the same features throughout their seasonal periods of occurrence. Persistent differences in nekton use of adjacent intertidal creeks might be explained by behavioral selection for preferred conditions and reoccupation of selected creeks. Geomorphological variations are significant among sites and must be considered when assessing factors affecting nekton use along salinity and other environmental gradients.
