“…Fuji et al . () reported better feeding conditions and consequently good body conditions and growth rates of juvenile temperate seabass in the Yura River estuary compared to adjacent coastal areas. High prey densities and/or good feeding conditions of juvenile seabass have also been reported for several other estuaries (Iwamoto et al ., ; Islam et al ., ).…”

“…Adult seabass were collected on three or four occasions in each of 2 consecutive years (28 January and 1, 3, 4 February 2011; 11, 18 January and 14 February 2012). A similar sampling period was chosen in each year to ensure that seabass were sampled during the spawning season (from January to February; Fuji et al, 2013). The SL of all adult samples were measured, and their sex was identified.…”

“…eelgrass beds (Hatanaka and Sekino, 1962a), sandy beaches (Fuji et al, 2010), tidal flats (Hibino et al, 2002) and estuaries (Matsumiya et al, 1982;Fuji et al, 2010;Iwamoto et al, 2010). Recently, the importance of estuaries as nursery areas for temperate seabass has been emphasised by several previous studies (Fuji et al, 2010(Fuji et al, , 2011(Fuji et al, , 2013Iwamoto et al, 2010;Islam et al, 2011). Evaluating the relative contribution of estuaries to adult populations is noteworthy to assess estuarine nursery values.…”

Otolith Sr:Ca ratios were used to evaluate the contribution of estuarine nursery areas to the temperate seabass (Lateolabrax japonicus) population in Tango Bay, the Sea of Japan. Otolith Sr:Ca ratios of juveniles collected from freshwater, brackish and coastal areas were analysed to determine a criterion for distinguishing whether individuals used estuarine or coastal areas as nurseries. Otolith Sr:Ca ratios of adult seabass collected around Tango Bay were also analysed to detect the records of salinity that juveniles experienced and to estimate the contribution of each habitat. Sr:Ca ratios of the edges of otoliths of juveniles from freshwater areas were 2.4 9 10 À3 in average, which were significantly lower than those of juveniles collected from a coastal area (4.9 9 10 À3 in average) owing to differences in salinity conditions among these areas. Based on the threshold criterion determined by this difference, 39 out of 107 (36%) adult seabass were estimated to have used the estuary as a nursery during their juvenile stage according to their Sr:Ca chronologies. Despite the small area covered by estuarine nurseries compared with coastal waters, the Yura River estuary contributed considerably to the adult seabass population. This indicates estuaries play an important role as nurseries for seabass juveniles, and it should be noted that the estuaries are important nurseries to conserve the stocks of coastal fishes.

“…Since salinity is not a limiting factor for the survival of L. japonicus , choosing a foraging ground that favors growth could be an important factor influencing the migratory behaviors of L. japonicus. Larval and juvenile L. japonicus feeding in the different habitats could lead to different growth, survival, and recruitment success . The higher productivity and prey abundance might attract most juvenile and young L. japonicus feeding in the estuaries.…”

Rationale:Otolith strontium:calcium (Sr:Ca) ratios have been extensively used to study fish migration across a river, estuary and ocean at each life stage. However, otolith Sr:Ca ratios only explain partial variations in salinity and quantitative reconstruction of salinity history of fishes remains a challenge. Using a euryhaline fish Lateolabrax japonicus as an example, this study demonstrated an isotopic method of quantitatively reconstructing the salinity histories and habitat uses of the fish. Methods:Otolith oxygen stable isotopic ratios (δ 18 O oto values) were measured using a mass spectrometer for subsamples sequentially milled from the otolith core to the edge, and otolith Sr:Ca ratios were measured by an electron probe microanalyzer for the comparison. The mean water temperature within the studied area in the time period of each milled subsample was estimated from the Copernicus database. Based on an isotopic fractionation equation, each δ 18 O oto value and water temperature pair determined the water δ 18 O value, which was then converted into salinity using published linear equations or an equation that was newly generated for this study.Results: Individual fish clearly revealed different preferences in habitat use. The retrospectively reconstructed salinity history indicated that most L. japonicus inhabit and can spawn in seawater as well as in brackish estuaries. Few fish lived in freshwater during the young stage based on the analysis of δ 18 O oto profiles; however, otolith Sr:Ca ratios can only reveal freshwater residence and cannot distinguish residence in brackish water or seawater. Conclusions:This study demonstrated that otolith temporal microstructure and δ 18 O oto values are well-suited approaches for quantitative reconstruction of salinity histories of the fish. This method can improve the understanding of the habitat uses of other fishes inhabiting diverse habitats among the rivers, estuaries and oceans.

“…Some of the juveniles migrate upstream in rivers, using either tidal flows or salt wedges , while others do not. Fuji et al (2014) found that the growth of juveniles moving upriver from the Yura River Estuary (Japan) was initially poor, but rapidly increased during the time spent in the river, possibly because of the better availability of food. In the modeling context shown in Fig.…”

To enhance numerical modeling of the coastal ecosystem complex (CEC), we reviewed the CEC and related concepts along with the current coastal ecosystem model framework in this study. We identified two model implementation paths from the initial objectives to numerical models: specific model building, and the use of existing model frameworks. As the CEC is still at the conceptual stage, both paths are possible. Four important ecological features of CEC modeling (population connectivity, habitat heterogeneity, ontogeny of organisms, and trophic interactions) were also identified. Models for population connectivity, species distributions, life histories, and food webs were categorized using these features. We found that some previously established concepts (between-habitat interactions, coastal ecosystem mosaic, and seascape nursery) overlap with the CEC concept. Several existing integrated model frameworks were reviewed, focusing on their potential to simulate CEC processes. Building specific models for the CEC at the current conceptual stage will be challenging, and modification of existing models will be needed if they are to be used for CEC modeling. Habitat function, ontogenetic development in early life stages, and recruitment variability are important factors when modifying existing models for the development of CEC models. Although model complexity should become high to reproduce observed ecoclogical processes, an intermediate level of model ccomplexity is feasible to decrease parameter uncertainty in models for fisheries management.
