“…Ongoing studies suggest that planktonic red drum are transported into the estuary when coastal waters are driven into the system through the Aransas Pass tidal inlet as a result of tidal or non-tidal forcing (Brown et al 2000). In addition, planktonic larvae are capable of migrating vertically in response to flood and ebb tides, and probably use currents for transport into the estuary (Holt et al 1989).…”

A novel approach was used to study the settlement of red drum Sciaenops ocellatus larvae from the coastal Gulf of Mexico to a seagrass meadow in the Aransas Estuary, Texas, during an entire recruitment season (September through November 1999). Differences in the δ 13 C and δ 15 N of the food webs supporting red drum while in the planktonic and estuarine habitats were characterized and used to identify post-settlement individuals in the process of completing the isotopic shift between the planktonic and estuarine signatures (transitional larvae). An empirical model was used to estimate the rate of change in the isotopic composition of transitional red drum to back-calculate size at settlement (L sett ; mm standard length: SL) and time since settlement (T sett ; d). During the period of study, there were 4 to 5 ‰ differences in the δ 13 C and δ 15 N of planktonic larvae and 'large' settlers that had equilibrated to estuarine food sources. Red drum captured simultaneously exhibited variability in L sett and T sett values, indicating that they had settled at a range of sizes and over several days. Examination of length-frequency distributions of L sett estimates indicated that the smallest settlers were about 4 mm SL, peak size at settlement was 6 to 8 mm SL, and the largest settlers were 10 to 11 mm SL. Settlement dates derived from T sett indicated that a brief settlement pulse occurred during the latter half of September and that new settlers appeared on a daily basis throughout October and early November. The relatively continuous settlement pattern suggests a consistent supply of potential settlers to the estuary. The approach used in this study provides a fine-scale temporal resolution for the examination of settlement patterns in marine fishes that exhibit a distinct habitat transition and consequent dietary shift during early life.

Hence, settlement is constrained by the size and/or age at which larvae become competent to settle. Identification of the sizes at which larvae are most likely to settle would be useful when quantifying the abundance of potential settlers (McCormick 1994, Danilowicz 1997.Another critical aspect of estuarine recruitment involves the temporal scales over which settlement occurs. By examining fine-scale temporal patterns of settlement, it is possible to determine whether it occurs periodically, in pulses, or as the result of continuous input of new recruits (Doherty 1991). Such information is crucial for identifying the processes that transport larvae to estuaries and evaluating the relationship between larval supply and settlement (Miller 1988, Milicich et al. 1992, Shenker et al. 1993.This study attempts to characterize the fine-scale temporal settlement patterns of red drum...

“…Therefore, wind-driven tides are critical in this region for regulation of estuarine salinity. Additionally, tides are critical for post-larval stocking of many estuarine dependent species (Epifanio 1995, Brown et al 2000, Möller et al 2009), and brown shrimp are highly dependent on tides to transport them to vegetated marshes where they settle (Zimmerman et al 2000, Haas et al 2001, Roth et al 2008. While the increase in onshore currents earlier in the season may have affected stocking rates, the data were not able to show this connection.…”

Relating large-scale climate variability to local species abundance: ENSO forcing and shrimp in Breton Sound, Louisiana, USA

Climate creates environmental constraints (filters) that affect the abundance and distribution of species. In estuaries, these constraints often result from variability in water flow properties and environmental conditions (i.e. water flow, salinity, water temperature) and can have significant effects on the abundance and distribution of commercially important nekton species. We investigated links between large-scale climate variability and juvenile brown shrimp Farfantepenaeus aztecus abundance in Breton Sound estuary, Louisiana (USA). Our goals were to (1) determine if a teleconnection exists between local juvenile brown shrimp abundance and the El Niño Southern Oscillation (ENSO) and (2) relate that linkage to environmental constraints that may affect juvenile brown shrimp recruitment to, and survival in, the estuary. Our results identified a teleconnection between winter ENSO conditions and juvenile brown shrimp abundance in Breton Sound estuary the following spring. The physical connection results from the impact of ENSO on winter weather conditions in Breton Sound (air pressure, temperature, and precipitation). Juvenile brown shrimp abundance effects lagged ENSO by 3 mo: lower than average abundances of juvenile brown shrimp were caught in springs following winter El Niño events, and higher than average abundances of brown shrimp were caught in springs following La Niña winters. Salinity was the dominant ENSO-forced environmental filter for juvenile brown shrimp. Spring salinity was cumulatively forced by winter river discharge, winter wind forcing, and spring precipitation. Thus, predicting brown shrimp abundance requires incorporating climate variability into models.

“…Physical transport in the vicinity of barrier island inlets is strongly influenced by tides, local geometry, and bathymetry, which create a characteristic circulation pattern (e.g. Stommel & Farmer 1952, Zimmerman 1981, Brown et al 2000, Hench et al 2002 that is expected to hydrographically isolate adjacent water bodies on the landward side of barrier islands , Hench & Luettich 2003.

Basin-scale patterns of mtDNA differentiation and gene flow in the bay scallop Argopecten irradians concentricus

The bay scallop Argopecten irradians concentricus Say is a commercially and recreationally important species along the East Coast of the US that consistently shows evidence of recruitment limitation. To determine if limited planktonic larval exchange between populations inhabiting lagoonal basins or sounds contributes to recruitment limitation in central North Carolina, a hypervariable portion of mtDNA (885 bp) was sequenced from 219 adults from 4 sounds (Topsail, Bogue, Back, and Pamlico), 3 of which (Bogue, Back, and Pamlico) are connected by inshore waterways. Although the largest sound (Pamlico) harbored the greatest genetic diversity, diversity was high in all 4 sounds, with no evidence of recent bottlenecks. An analysis of molecular variance indicates significant genetic structure among sounds (φ CT = 0.0069, p = 0.023); all pairwise comparisons among sounds were significant, with the exception of those involving Pamlico Sound. Despite being connected by a short (3 km) inshore waterway, adjacent Bogue and Back Sounds were highly significantly differentiated (φ CT = 0.0145, p = 0.000). Coalescent-based estimates of gene flow indicated that most sounds exchange ≤ 4 migrants each generation. Bogue and Back Sound populations, which were heavily impacted by a localized red tide outbreak in 1987 and which subsequently experienced a recruitment failure, each receive < 4 migrants each generation from all other sounds combined. Dynamic physical processes in the vicinity of Beaufort Inlet can explain such limited larval exchange between Bogue and Back Sounds, but if dispersal is primarily controlled by tidally dominated surface flow, net dispersal distances may be limited throughout the region. Therefore, patterns of gene flow and genetic differentiation are consistent with the hypothesis that individual sounds are demographically independent and are closed with respect to fishery management issues.
