“…Similar results were mentioned by MORGAN et al (1997) for Coullana canadensis in the Columbia River Estuary, USA, where the abundance distribution mirrors that of SPM. Hough andNaylor (1991, 1992), however, observed tide-related vertical migrations of E. affinis in the midestuary region of the Conway River Estuary in Wales. In our study, patterns of abundance and distribution of A. tonsa did not match those of SPM, suggesting that additional mechanisms beyond hydrodynamic processes would maintain the populations in the inner zone of the Bahía Blanca Estuary.…”

“…This phenomenon is well described for fishes that are spawned offshore and subsequently enter estuaries (Boehlert and Mundy 1988;Shanks 1995). However, for particular early life stages several field and laboratory studies identified endogenous rhythms in estuarine zooplankton and larval invertebrates (Forward 1988;Hough and Naylor 1992;Tankersley and Forward 1994) as well as fishes (Gibson 1978;Wippelhauser and McCleave 1988;Forward et al 1998). Behavioral plasticity in migration strategies is also documented for zooplankton (Forward 1988;Bollens and Frost 1991) and thought to be prevalent in fishes (Neilson and Perry 1990).…”

We investigated the degree of flexibility in retention strategies of young fishes in the low-salinity zone (LSZ) of the San Francisco Estuary during years of highly variable river flow. We conducted depth-stratified sampling over three full tidal cycles in each year from 1994 to 1996. In 1994, exotic striped bass (Morone saxatilis), native longfin smelt (Spirinchus thaleichthys), and exotic yellowfin goby (Acanthogobus flavimanus) migrated tidally, occurring near the surface on flood tides and near the bottom on ebb tides. This strategy may have facilitated retention, because landward residual currents were absent in this drought year. During 1995, this behavior persisted for striped bass and yellowfin goby, even though landward residual currents were present under high river-flow conditions. In moderate river-flow conditions (1996), longfin smelt again migrated tidally, whereas at another station adjacent to shallow bays, longfin smelt, striped bass, and native delta smelt (Hypomesus transpacificus) migrated on a reverse diel cycle, occurring near the surface by day and at depth by night. Reverse diel migration may facilitate horizontal transport and retention. Therefore, young fishes appeared to be behaviorally flexible in different environmental conditions to maximize retention. Vertical migrations may also enhance feeding success because zooplankton prey similarly migrated in the LSZ. Our study underscores the value of interdisciplinary studies in a variety of environmental conditions to decipher the range of organism behaviors promoting transport and retention in optimal habitats.

“…Available evidence suggests that these movements are primarily controlled by endogenous clocks (Forward & Tankersley 2001). In addition to Uca pugilator Stage-1 zoeae (López-Duarte & Tankersley 2007), circatidal rhythms in swimming activity that underlie STST have been reported for larval and adult phases of several other crustaceans, including the copepod Eurytemora affinis (Hough & Naylor 1992), zoeae of Carcinus maenas (Zeng & Naylor 1996a,b,c, Duchêne & Queiroga 2001 and Rhithropanopeus harrisii (Cronin & Forward 1979, 1983, Forward & Cronin 1980, postlarvae and juveniles of Penaeus duorarium (Hughes 1972), ovigerous adult blue crabs Callinectes sapidus (Forward et al 2003), and Uca spp. meglaopae (Tankersley & Forward 1994).…”

Fiddler crab Uca pugilator larvae are released within estuaries near the time of high tide and are exported offshore to undergo development. Previous studies indicate that zoea-1 larvae use selective tidal-stream transport (STST) to migrate from adult habitats to shelf waters. In areas with semidiurnal tides, this behavior is mediated by a circatidal rhythm that is characterized by upward swimming toward the surface during ebb tide, followed by a descent toward the bottom during flood tide. We tested the hypothesis that U. pugilator zoeae from different tidal regimes possess activity rhythms that match local tidal patterns. Ovigerous crabs with late-stage embryos were collected from areas with semidiurnal, diurnal, and mixed tides and from an area within a microtidal coastal lagoon. Following hatching, swimming activity was monitored under constant conditions for 96 h. Zoeae from semidiurnal and diurnal regimes possessed activity rhythms with free-running periods that matched the tides at the collection sites (≈12.4 and 24.8 h, respectively). Crabs from beaches with mixed tides displayed asymmetrical oscillations in swimming activity with dominant periodicities that corresponded to the semidiurnal and diurnal constituents of the tides. Zoeae from microtidal areas possessed rhythms that were similar to those observed in crabs from areas with semidiurnal tides. At all locations, peaks in activity occurred during the time of expected ebb currents, which is consistent with STST behavior favoring seaward transport. Differences in larval activity patterns suggest that STST behaviors are controlled by separate circatidal and circalunidian clocks or paired circalunidian clocks coupled in antiphase.
