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.

Feeding conditions of larval fish across mesoscale (>1 to 100 km) gradients in prey concentrations are often attributable to prevailing circulation patterns, frontal features, and interacting spa...

“…Sampling planktonic larval fishes is a method used to develop an index of stock abundance and is often used as a management tool to estimate reproduction and year-class strength (Uphoff, 1989;Sammons and Bettoli, 1998). Investigating the early life histories and population dynamics of larval and juvenile fishes is important because year-class strength is established during these early stages (Cushing, 1990).…”

“…Low temperatures experienced by larvae/juveniles in species spawning in winter can reduce ingestion rates, and, although maintenance requirements and activity may be lower, often result in reduced or negative growth. For example, winter temperature minima have been found to be significantly related to year-class strength in striped bass Morone saxatilis (Uphoff 1989), cod Gadus morhua (Brown et al 1989) and herring Clupea harengus (Stocker & Haist 1984, Anthony & Fogarty 1985.…”

ABSTRACT. Laboratory experiments were conducted on juvenile summer flounder Paralichthys dentatus (41 to 80 mm total length) to determine low temperature tolerance (2 to 3 "C) a t 10, 20, and 30 %salinity, and to measure feeding rate, assimilation efficiency, growth rate and growth efficiency at 2, 6, 10. 14, 18 "C and 10, 20 and 30 '7' salinity. There was 100 % sunival at temperatures above 3 'C, suggesting that juvenile summer flounder are able to survive most winter water temperatures encountered in north/central Mid-Atlantic Bight (MAB) estuaries. Mortality was 42 % after 16 d at 2 to 3 'C, and was highest in fish < 50 mm TL (1 g). Mean specific growth rates were not significantly different between 2 and 10 "C (mean = 0.14 % d-'), and these rates were not significantly different from zero. Mean growth rate increased to 2.4 "0 d-' at 14 ' C and 3.8 O/ O d-' at 18 OC. Ad libitum feeding rate showed a similar relationship to temperature. Mean assimilation efficiency (60.1 %) was not affected by temperature. Mean growth efficiency ( K , ) was significantly lower at 6 "C (-23.1 "h) than a t 14 and 18 "C (18.4 and 22.1 %, respectively), and was highly variable. Salinity had no significant effect on any parameters measured, suggesting that factors other than salinity are controlling spatial distributions. Mortality resulting from acute exposure to low temperature probably occurs during one 2 to 4 wk period each winter Recruitment success from north/central MAB estuaries may be lower in years with late winter cold periods (i.e. March vs December) due to increased numbers of fish being exposed to lethal low temperatures. Additional mortahty probably results from low growth rates caused by sub-optimal temperatures (i.e. < 10 "C) throughout the spring. The annual contribution of new recruits from northern estuanes appears to b e dependent on winter temperature regime, particularly on the magnitude and timing of temperature minima.
