“…This study provides evidence for spatially coupled food webs in coastal New England waters where striped bass act as apex predators in the saltmarsh during the summer and a vector for saltmarsh productivity as prey in the coastal ocean to apex consumers such as larger predatory fishes, sharks, and seals during their southern migration in the fall. Although we demonstrate a strong contribution from saltmarsh-derived productivity to striped bass tissue, our results and previous diet studies suggest the diet of striped bass, in terms of specific prey items, is quite flexible (Pautzke et al 2010). We observed no correlation with body size or weight and isotope value, indicating that striped bass diets likely remain flexible through the juvenile and small adult size classes.…”

Each winter, populations of striped bass (Morone saxatilis) migrate north from the coastal mid-Atlantic region of the US to the coastal waters of New England. During this migration, striped bass spend significant time in estuaries and saltmarshes, presumably to forage. However, the extent to which saltmarsh productivity supports striped bass remains unresolved. We used a three-isotope Bayesian mixing model to determine the relative contribution of three primary producers [C4 saltmarsh cordgrass (Spartina spp.), phytoplankton, and benthic diatoms] to striped bass tissue. Phytoplankton (51 % contribution) and Spartina-derived sources (44 % contribution) are the primary sources of production to striped bass, while benthic diatoms made a relatively small contribution (5 %). Our results highlight the importance of saltmarshes to striped bass by showing that primary producers unique to saltmarsh ecosystems support a large proportion of striped bass production.

“…During this time, the large subadult (30-50 cm) and small adult (50-70 cm) striped bass spend a significant amount of time in New England estuaries and saltmarshes (Mather et al 2009;Pautzke et al 2010). They show high site fidelity, migrating to the same locations year after year (Kneebone et al 2014;Mather et al 2013b).…”

“…Tagged M. saxatilis stayed in PIE for an average of 72·2 days in summer with 60% of the tagged fish staying longer than 30 days (Pautzke et al , 2010). All tagged M. saxatilis exited the study area by 31 October 2006 (Pautzke et al , 2010). Almost three‐quarters (70%, n = 32) were detected either in one or both of two southern arrays (LIS and DE).…”

Almost three-quarters of the 46 young adult and sub-adult striped bass Morone saxatilis that were acoustically tagged in Plum Island Estuary, Massachusetts, U.S.A., in the summer of 2006 were detected in one or more southern coastal arrays during their autumn migration. On the basis of the trajectories along which these M. saxatilis moved from feeding to overwintering areas, three migratory groups emerged. After leaving Plum Island Estuary, about half of the fish were detected only in a mid-latitude array, Long Island Sound. The other half of the tagged fish were detected during autumn and winter in a more southern array, the Delaware Estuary. This latter group of fish may have used two routes. Some travelled to the Delaware Estuary through Long Island Sound while other fish may have taken a second, more direct, coastal route that did not include Long Island Sound. Consequently, a seemingly homogeneous group of fish tagged at the same time in the same non-natal feeding location exhibited a diversity of southward movement patterns that could affect population-level processes. These three groups that differed in overwintering location and migration route could be movement contingents with migratory connectivity.

“…Individuals of these 3 species undertake broad-scale seasonal migrations of 100s to 1000s of kilometers along the Atlantic coast of the United States but can exhibit site fi delity in summer feeding and nursery habitats (Ng et al, 2007;Taylor et al, 2007;Pautzke et al, 2010;Turnure, 2010). They occupy upper trophic levels in mid-Atlantic estuarine food webs and are responsible for the transfer of nutrients and energy between benthic and pelagic compartments within estuaries and between estuaries and the coastal ocean (Hagy, 2002;Krause et al, 2003;Johnson et al, 2009).…”

Residence time and habitat duration for predators in a small mid-Atlantic estuary

Small individuals <500 mm TL were likely to remain in the estuary longer at warmer temperatures than were large individuals. Size-dependent temperature responses were similar to optimal temperatures for growth reported in previous studies. Freshwater discharge also influenced residence time. All species were likely to remain in the estuary until freshwater discharge rates fell to a value associated with the transition of the estuarine state from a partially to fully mixed state. This transition weakens flows into the upstream salt front where prey concentrations usually are high. Time of estuarine residence appeared to be regulated by temperatures that controlled scopes for growth and the indirect effects of freshwater discharge on prey productivity and concentration. Changes in the seasonal phenology of temperature, precipitation, and human water use could alter the durations over which small estuarine tributaries serve as suitable habitats.
