“…In contrast to the above findings, other studies of juvenile fishes have found negative relationships between abundance and river discharge. Juvenile Gulf menhaden abundance was negatively associated with Mississippi River discharge (Govoni 1997), and abundance of age-0 Japanese seaperch Lateolabrax japonicus showed an inverse correlation with Chikugo River discharge (Shoji and Tanaka 2006). In our study, the pinfish was the only species for which age-0 fish abundance was negatively related to river discharge.…”

Understanding the relationships between river discharge and recruitment of estuarine fishes is important because of hydrological alterations caused by anthropogenic water withdrawals. Varying river discharge alters salinity, turbidity, nutrient levels, and detrital concentrations, all of which affect estuarine biota. The lower Suwannee River, Florida, is one of the few remaining large-river systems in the United States that has no major impoundments. We assessed the relationship between seasonal river discharge and relative abundance, growth, and mortality of estuary-dependent age-0 fish of five species in the Suwannee River estuary. We analyzed 9 years of data (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005) collected as part of a long-term, fishery-independent monitoring program. The results showed a positive relationship between relative abundance and river discharge for age-0 spotted seatrout Cynoscion nebulosus, sand seatrout C. arenarius, and red drum Sciaenops ocellatus. The pinfish Lagodon rhomboides was the only species for which relative abundance was negatively related to river discharge; the relative abundance of spot Leiostomus xanthurus was not significantly related to changes in discharge. Instantaneous daily growth (G) estimates were positively related to river discharge for all species except spotted seatrout, for which a negative correlation was found. Instantaneous daily mortality (Z) estimates were positively correlated with river discharge for sand seatrout, pinfish, and red drum. The G : Z ratios for pinfish and early recruiting sand seatrout were negatively related to river discharge, indicating that recruitment potential declined with higher discharge. Changes in freshwater discharge affected the abundance, growth, and survival of these juvenile fishes, stressing the importance of water allocation decisions that affect estuarine fishes and the fisheries they support.

“…() reported a lower abundance of predatory shrimps in estuaries than in coastal areas in Sendai Bay. Shoji and Tanaka () also described lower abundances of potential predators of juvenile temperate seabass, including arrow worms and jellyfish in the Chikugo River estuary compared to coastal areas. These characteristics of estuaries lead to the relatively high nursery value of estuaries for temperate seabass.…”

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.

“…The influence of temperature, salinity, and river discharge on fish recruitment has been well documented (Drinkwater and Frank 1994;Grimes and Kingsford 1996;Gillanders and Kingsford 2002), but few comprehensive predictive models are available. Within estuaries, river discharge is correlated with growth and survival of young fish (North and Houde 2003;Shoji and Tanaka 2006). A threshold for the influence of salinity and flow rate on the abundance of young fish (including other estuarine-dependent, herringlike fish) is evident wherein a positive relationship becomes negative (Strydom et al 2002;Whitfield and Harrison 2003).…”

Relationship between Gulf Menhaden Recruitment and Mississippi River Flow: Model Development and Potential Application for Management

The Gulf menhaden Brevoortia patronus is one of the most abundant pelagic fishes in the northern coastal Gulf of Mexico (hereafter, "Gulf") and is the principal forage for various commercial and sport fishes, sea birds, and marine mammals. Part of the life history of Gulf menhaden is spent on the continental shelf and part is spent within estuaries. Adults spawn near the mouth of the Mississippi River, and larvae aggregate within the river plume front. Larval Gulf menhaden transit the continental shelf and enter estuaries of the northern Gulf as juveniles. Govoni (1997) demonstrated an association between the discharge of the Mississippi and Atchafalaya rivers and Gulf menhaden recruitment. In particular, he found an inverse association between Mississippi River discharge and estimated recruitment of half-year-old fish based on recruitment data from Vaughan et al. (1996). Vaughan et al. (2000) updated this relationship with a regression analysis. Here, we revisit the relationship with additional years of data through 2004. The inverse relationship continues to hold. In addition, we reframed this relationship to produce a 1-year-ahead prediction model for forecasting recruitment to age 1 from Mississippi River discharge; this model can be used in proactive fishery management. Finally, we revisited the stock assessment model of Vaughan et al. (2007) and demonstrated an improvement in model performance when information on annual river discharge was incorporated.The Gulf menhaden Brevoortia patronus is an exploited marine resource as well as an integral and key ecological component of the coastal northern Gulf of Mexico (hereafter, "Gulf")
