TL;DR: The composition of the caudal skeleton of fossil teleosts and the ontogeny of that of Hiodon, Elops, and Albula corroborate a one‐to‐one relationship of ural centra with these dorsal and ventral elements.
Abstract: The vertebral centra of Hiodon, Elops, and Albula are direct perichordal ossifications (autocentra) which enclose the arcocentra as in Amia. An inner ring of ovoid cells forms in late ontogeny from the intervertebral space inside the autocentrum. The chordacentrum is reduced or completely absent in centra of adult Elops, whereas it forms an important portion of the centra in adult Hiodon. The posterior portion of the compound ural centrum 3+4+5 is partially (Hiodon) or fully formed by the chordacentrum (Elops, Albula). The haemal arches and hypurals are fused medially by cartilage or bone trabecles of the arcocentrum with the centra, even though they appear autogenous in lateral view in Elops and Albula. The composition of the caudal skeleton of fossil teleosts and the ontogeny of that of Hiodon, Elops, and Albula corroborate a one-to-one relationship of ural centra with these dorsal and ventral elements. The first epural (epural 1) of Elops relates to ural centrum 1, whereas the first epural (epural 2) of Hiodon and Albula relates to ural centrum 2. In Albula, the first ural centrum is formed by ural centrum 2 only. With 4 uroneurals Hiodon has the highest number within recent teleosts. Juvenile specimens of Hiodon have eight, the highest number of hypurals within recent teleosts; this is the primitive condition by comparison with other teleosts and pholidophorids. Reduction of elements in the caudal skeleton is an advanced feature as seen within elopomorphs from Elops to Albula. Such reductions and fusions occur in osteoglossomorphs also, but the lack of epurals and uroneurals separates most osteoglossomorphs (except Hiodon) from all other teleosts.

TL;DR: A simple approach to ranking relative habitat value is to compare intraspecifi cifi c fi sh distributions with respect to habitat in different estuaries as discussed by the authors, which can assist in predicting the response of coastal fi sh populations to changes in these habitats.
Abstract: Many fi sh species use estuaries of the southeastern United States as nurseries (e.g. Skud and Wilson, 1960; Gunter, 1967), but coastal habitat degradation threatens many of the economically important fi sheries that rely on estuaries (Gilmore, 1995). The re-enacted Magnuson-Stevens Fishery Conservation and Management Act (MSFCMA) was developed to protect or enhance fi sheries habitats, by fi rst requiring information regarding the value of coastal habitats to the survival of marine organisms (e.g. Schmitten, 1996). A simple approach to ranking relative habitat value is to compare intraspecifi c fi sh distributions with respect to habitat in different estuaries. Associations between abundance and habitat can assist in predicting the response of coastal fi sh populations to changes in these habitats. Remarkably, such information is rarely available except for the most economically valuable species (Haedrich, 1983). Freshwater infl ows to estuaries of the southeast United States have been severely altered in the last 150 years and coastal development continues to divert more water away from estuaries (Stickney, 1984). The MSFCMA’s Essential Fish Habitat mandate provides a policy framework for identifying the effects of reduced freshwater infl ows on estuarine-dependent species. Yet researchers and managers often characterize species as estuarine-dependent more on intuition than rigorous examination of data. Able and Fahay (1998) outlined three criteria for defi ning estuarine-dependence: 1) predictable use Nursery habitats for ladyfi sh, Elops saurus, along salinity gradients in two Florida estuaries

TL;DR: The tarpon and ladyfish are popular gamefishes that inhabit coastal marshes and mangroves and are thermophilic (preferring warm water), euryhaline (tolerant of a wide range of salinity), and are capable of surviving at low oxygen concentrations.
Abstract: : Species profiles are literature summaries of the taxonomy, morphology, distribution, life history, habitats, and environmental requirements of coastal species of fishes and aquatic invertebrates. They are designed to assist in environmental impact assessment. The tarpon and ladyfish are popular gamefishes. Adults spawn offshore. Larval and juvenile stages inhabit coastal marshes and mangroves. Both species are thermophilic (preferring warm water), euryhaline (tolerant of a wide range of salinity), and are capable of surviving at low oxygen concentrations. Wetlands destruction and degradation negatively affect these species by reducing nursery areas.

TL;DR: The present study is the first confirmed report of an aporocotylid infecting a member of Elopiformes as well as the first reported of an infection in an elopomorph outside of Australia and New Zealand or in marine waters.
Abstract: Monotypic Paracardicoloides Martin, 1974 is emended based on supplemental observations of 2 voucher specimens of Paracardicoloides yamagutii Martin, 1974. Features of the anterior sucker, esophagus, and intestine as well as the male and female genitalia previously attributed to, or omitted from the diagnosis and description of, this fluke are resolved and further detailed herein. The holotype of P. yamagutii, originally deposited in the Allan Hancock Parasitology Collection, apparently has been lost, and Queensland Museum voucher G222650 is designated as the neotype. Elopicola nolancribbi n. gen., n. sp. infects the ladyfish, Elops saurus, (Elopiformes: Elopidae) in the north-central Gulf of Mexico. The new genus resembles Paracardicoloides by having the combination of a bowl-shaped anterior sucker, inverse U-shaped intestine, short posterior ceca, post-cecal ovary, pre-ovarian ootype, compact uterus, and prominent excretory arms and vesicle. It differs from Paracardicoloides by lacking robust t...
