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.

Length–weight relations (LWRs) were estimated for 44 fish species, representing 23 families, collected from an unprotected coastal biological corridor of the Yucatan Peninsula. The following species were studied (in alphabetical order): Acanthostracion quadricornis (Linnaeus, 1758); Albula vulpes (Linnaeus, 1758); Anchoa hepsetus (Linnaeus, 1758); Anchoa lamprotaenia Hildebrand, 1943, Anchoa lyolepis (Evermann et Marsh, 1900), Anchoa mitchilli (Valenciennes, 1848); Archosargus rhomboidalis (Linnaeus, 1758); Ariopsis felis (Linnaeus, 1766); Bagre marinus (Mitchill, 1815); Bairdiella chrysoura (Lacepède, 1802); Caranx latus Agassiz, 1831; Chaetodipterus faber (Broussonet, 1782); Chriodorus atherinoides Goode et Bean, 1882; Cynoscion arenarius Ginsburg, 1930; Elops saurus Linnaeus, 1766; Eucinostomus argenteus Baird et Girard, 1855; Eucinostomus gula (Quoy et Gaimard, 1824); Eucinostomus harengulus Goode et Bean, 1879; Harengula jaguana Poey, 1865; Hyporhamphus unifasciatus (Ranzani, 1841); Lagodon rhomboides (Linnaeus, 1766); Lutjanus griseus (Linnaeus, 1758); Menticirrhus americanus (Linnaeus, 1758); Menticirrhus littoralis (Holbrook, 1847); Menticirrhus saxatilis (Bloch et Schneider, 1801); Mugil curema Valenciennes, 1836; Mugil trichodon Poey, 1875; Oligoplites saurus (Bloch et Schneider, 1801); Opisthonema oglinum (Lesueur, 1818); Opsanus beta (Goode et Bean, 1880); Orthopristis chrysoptera (Linnaeus, 1766); Prionotus tribulus Cuvier, 1829; Rypticus maculatus Holbrook, 1855; Selene vomer (Linnaeus, 1758); Sphoeroides spengleri (Bloch, 1785); Sphoeroides testudineus (Linnaeus, 1758); Strongylura notata (Poey, 1860); Strongylura timucu (Walbaum, 1792); Symphurus plagiusa (Linnaeus, 1766); Synodus foetens (Linnaeus, 1766); Trachinotus carolinus (Linnaeus, 1766); Trachinotus falcatus (Linnaeus, 1758); Trachinotus goodei Jordan et Evermann, 1896; Urobatis jamaicensis (Cuvier, 1816). A new maximum standard length (SL) was recorded for Anchoa lamprotaenia. Positive allometric growth was reported in ten species, negative allometric growth in sixteen species, and isometric growth in eighteen species.
