“…Although the position of ETM varies seasonally and at short time scales due to variations in freshwater input and wind forcing (North and Houde, 2001), this indicates that the ETM was displaced upstream likely due to the reduced flow imposed during filling of the Alqueva reservoir. ETM has been identified as an important nursery area in several estuaries, such as the St. Lawrence (Winkler et al, 2003) and Chesapeake Bay (North and Houde, 2003), either by providing protection from predators (Cyrus and Blaber, 1987) or due to high productivity levels (Roman et al, 2001). However, in this study, ichthyoplankton diversity and abundance was low in the ETM.…”

“…In addition to temperature and salinity (Blaxter, 1992;Motos et al, 1996), several other parameters such as seston (Cyrus and Blaber, 1992;North and Houde, 2003), suspended organic matter, chlorophyll a and river flow (Loneragan and Bunn, 1999;Whitfield and Harrison, 2003) decisively affect spatial organization of estuarine communities (Jaureguizar et al, 2004). The start of most species' reproduction periods coincide with periods of greater food availability, thereby ensuring greater larval development success and explaining the link between spawning dynamics and chlorophyll a and seston concentrations.…”

The species composition, abundance and distribution of the ichthyoplankton of the Guadiana estuary and adjacent coastal area were studied in relation to several environmental parameters. Sampling occurred during new moon Spring tides, at the ebb and flood, at nine stations, from March 2002 to February 2003. Temperature, salinity, dissolved inorganic macronutrients, seston and organic matter and chlorophyll a were determined at each station. A total of 22 and 34 fish eggs and larvae taxa were identified, respectively. The highest abundances were registered in the lower and middle part of the estuary, probably due to the presence of species that use the estuary as a preferential spawning ground, mainly Pomatoschistus spp. and Engraulis encrasicolus sensu lato. Temporal patterns of occurrence of ichthyoplankton allowed each species' spawning season to be determined. Two taxa dominated the ichthyoplanktonic community during spring and summer (Pomatoschistus spp. and E. encrasicolus), whereas Sardina pilchardus was particularly abundant during autumn and winter. The forcing variables responsible for community structure were chlorophyll a and seston for eggs, while temperature, salinity and nitrite explained the larval component. Comparisons of the results with previous ichthyoplankton studies of the Guadiana estuary conducted before the Alqueva dam was built also indicate that river flow has an important impact on the distribution and abundance of ichthyoplankton in the estuary.

“…Subsequently, it was demonstrated that frequencies of favorable or unfavorable climate patterns control spring temperatures and precipitation, as well as the abundance and types of prey available to anadromous fish larvae and juveniles in Chesapeake Bay, including striped bass (Wood 2000, Kimmel & Roman 2004. North & Houde (2003) reported higher concentrations of fish larvae and zooplankton prey in the estuarine turbidity maximum (ETM), a convergence zone at the head of many coastal plain estuaries (Schubel 1968), in a wet year when the ETM feature was enhanced.Our research was conducted in the upper Chesapeake Bay, in the region of the salt front and ETM . In Chesapeake Bay and the St. Lawrence River, there is evidence of a link between the survival of anadromous fish larvae, e.g.…”

Causes of recruitment variability in young-of-the-year (YOY) striped bass Morone saxatilis from Chesapeake Bay were investigated based on (1) surveys from 2001 to 2003 to document spatio-temporal variability in abundance of larval striped bass, zooplankton prey, and feeding success of larvae; (2) a synthetic analysis (1996, 1998, 1999, 2001 to 2003) to describe how environmental factors and prey affect recruitment success; and (3) a 10 yr analysis (1993 to 2002) of inter-annual differences in spatial and temporal patterns of copepods and cladocera eaten by striped bass larvae. Striped bass YOY recruitment levels varied >11-fold in the 6 years examined. In those years, mean daily freshwater flows from the Susquehanna River to the bay in March and April varied > 2-fold and controlled distribution and apparent survival of striped bass larvae. Strong recruitments of YOY striped bass were associated with matches in space and time of larval striped bass and high concentrations of zooplankton prey, especially the copepod Eurytemora affinis and cladoceran Bosmina longirostris. The strongest year classes (1996, 2003) were produced in years of high freshwater flow, characterized by a high abundance of feeding-stage larvae and a spatio-temporal match between peak abundance of larvae and zooplankton prey. Enhanced feeding opportunities were most pronounced in high freshwater-flow years (1996, 1998, 2003), when larvae and zooplankton prey were strongly associated with, and apparently retained near, the estuarine turbidity maximum. First-feeding larvae fed more successfully in a high-flow year (2003; prey incidence 91%) than in a drier year (2001; prey incidence 35%). A regression model that may have forecasting potential was developed to describe recruitment of YOY striped bass for the years from 1985 to 2006. The model includes spring freshwater flow and air temperatures to predict age-0 striped bass recruitment strength (R 2 = 0.65). Flow and temperature control environmental and hydrographic conditions that strongly influence spatio-temporal overlap of larval striped bass and zooplankton. The model provided accurate recruitment forecasts for 2007 and 2009, but was less successful in 2008, a year of exceptionally low recruitment.

“…Some authors suggest that in brackish and other transitional waters species richness is lower than in freshwater and marine habitats (Remane, 1934). Previously published data show that freshwater zooplankton species, mostly rotifers and cladocerans, show low tolerance to increasing salinity (Hart et al, 1991; Boronat et al, 2001;Nielsen et al, 2003Nielsen et al, , 2012North and Houde, 2003;Waterkeyn et al, 2011).…”

“…This species was absent in subsaline lakes, implying its low tolerance to habitat salinization (Boronat et al, 2001). North and Houde (2003) suggested that most of B. longirostris in their investigation were found in salinities < 1 psu (2000 mS.cm x1 ). There are also indications that at salinities above 1000 mg.L x1 (2000 mS.cm x1 ), reduction in abundance and species richness in zooplankton emerging from dormant egg deposits occurs (Brock et al, 2005).…”

-Investigating forces driving the structure of aquatic communities has long been an important issue in ecology. In the present study, we focused on the effects of changed water supply for aquaculture ponds on phytoplankton, zooplankton and macrozoobenthos communities during two seasons of rearing common carp. We compared these communities between two types of inflow water: surface sources of watera reservoir pond, two open wells and a small stream and groundwater -deep tube well. Significant changes were observed in environmental variables after the introduction of the groundwater source: oxygen concentration and water hardness decreased, while conductivity, phosphorus and un-ionized ammonia increased. Results revealed that all investigated groups, except Mollusca (macrozoobenthos), decreased in species richness, abundance and biomass due to changed water chemistry, but differed in the level of susceptibility. Rotifera and Cladocera were the most affected showing a sharp decline in density and number of species since 66% of species disappeared from the ponds. The abundance of Copepoda was relatively high although significantly lower under new conditions, with adults being more tolerant to changed inflow water than nauplii larvae. Phytoplankton had the highest potential to replace previous species with newcomers more adapted to changed water chemistry, providing 36 immigrant species, whereas 49 became extinct. Although mainly influenced by fish predation, Chironomidae (macrozoobenthos) were undoubtedly affected by changed water chemistry. These results suggest profound changes in three key ecological groups produced by significant changes of important environmental variables and water quality after the shift from surface to groundwater supply.
