“…Telemetry techniques, which track and determine the location of individuals in 'real-time', show great promise as a method to determine links between juvenile and adult habitats. Szedlmayer & Able (1993) used ultrasonic transmitters to estimate residence time and movements of juvenile summer flounder Paralichthys dentatus in a subtidal creek. All tagged fish eventually moved out of the creek and it was suggested that this was part of a seasonal migration to the adult habitat.…”

“…This suggests a large influx of fish moving inshore and dispersing over intertidal areas with the flooding tide. Wirjoatmodjo and Pitcher (1984) in Northern Ireland and Szedlmayer and Able (1993) in New Jersey, USA, tracked flounder using ultrasonic telemetry. The authors demonstrated that these fish follow the tide and that frequency, direction, distance, speed and duration of movement were all significantly linked to tidal dynamics.…”

“…For species using bays as nurseries, approaches used to assess the importance of the nursery habitat have often been qualitative, and quantitative approaches have usually been indirect. Some authors have assessed importance as the proportion of the life history (Cyrus & Martin 1991) or amount of time spent in a nursery (Szedlmayer & Able 1993). Many authors have determined the importance of nursery habitats based on the abundance of juvenile fishes in a specific nursery (Reichert & van der Veer 1991) or by comparing abundances among several nursery areas (Kerstan 1991).…”

Trace elements in otoliths indicate the use of open-coast versus bay nursery habitats by juvenile California halibut

Many coastal fishes use inshore nursery habitats as juveniles, but it is often difficult to define which nursery areas supply most recruits to adult populations. We tested whether trace element concentrations in otoliths can be used to identify which of 2 nursery habitats (bays or shallow open coast) were occupied by juvenile California halibut. Juveniles from bays in 1998 had concentrations of Cu and Pb in their otoliths that were higher than those in open coast juveniles of the same year. This broad-scale difference between bay and open coast juveniles remained intact when bay juveniles from 1994 to 1997 were added to the comparison, and juvenile halibut could be assigned to their nursery habitat of origin quite accurately (83%) using otolith concentrations of Cu and Pb. At a finer spatial scale, otolith concentrations of Cu and Pb differed among individual bays, and fish from the same bay could differ among years, precluding their use as markers of nursery habitat use at these scales. Like halibut otoliths, sediments from bays had higher concentrations of Cu and Pb than open coast nursery sites, and this difference was consistent over 11 yr. Otoliths and sediments from individual bays, however, showed no correlation in Cu and Pb concentrations. The concentration of Cu and Pb in sediments and their deposition in otoliths were thus loosely matched at a broad scale, though the underlying cause of this link is not known. A discriminant model, parameterized using Cu and Pb levels in juvenile otoliths, was used to classify prior nursery habitat use by 19 larger halibut (of unknown origin). Eleven of these halibut had high levels of Cu and Pb in the part of the otolith deposited as a juvenile, and were classified as of bay origin. The other 8 halibut had low otolith Cu and Pb levels in the juvenile portion of their otoliths and were classified as having used open coast nurseries. Overall, our results suggest that this approach has the potential to allow identification of nursery habitat use by California halibut at a broad scale (bay vs open coast) but not at a fine scale (individual bays).
