Age and Growth of Larval and Juvenile Atlantic Croaker, Micropogonias Undulatus, from the Middle Atlantic Bight and Estuarine Waters of Virginia

New species of Cardicola (Digenea: Aporocotylidae) from heart of Atlantic croaker, Micropogonias undulatus (Perciformes: Sciaenidae), of the South Atlantic Bight.

Cardicola parvus n. sp. (Digenea: Aporocotylidae) infects the heart of Atlantic croaker, Micropogonias undulatus (Linnaeus, 1766) (Perciformes: Sciaenidae), in the South Atlantic Bight off Cow Island (34°38'49″N, 76°33'41″W, type locality) and Figure Eight Island (34°15'48″N, 77°44'27″W), North Carolina, USA, and off Jacksonville Beach (30°08'23″N, 81°20'52″W), Florida, USA. The new species is ...

Spatial Variation in Otolith Chemistry of Atlantic Croaker Larvae in the Mid-Atlantic Bight

Larval Atlantic croaker Micropogonias undulatus (1 to 7 mm in standard length) were collected on the east coast of the United States from North Carolina to Delaware during 2000. We defined 3 water-mass boundaries for potential groups of spawning Atlantic croaker using temperature and salinity measured at each sampling station. We tested the hypothesis that distinct otolith chemistries existed a...

Patterns of Larval Atlantic Croaker Ingress into Chesapeake Bay, USA

We compared ingress patterns of Atlantic croaker Micropogonias undulatus larvae into Chesapeake Bay, USA, with published ingress patterns through barrier island inlets, the accepted model for larval fish ingress. This model asserts that larvae ingress on night flood tides at the flooddominated side of the inlet and at all depths. At the Chesapeake Bay mouth and in the adjacent coastal waters, w...

Recruitment of Atlantic croaker, Micropogonias undulatus: Do postsettlement processes disrupt or reinforce initial patterns of settlement?*

Understanding the causes of fluctuations in population abundance is critical for ecologists and fishery biologists. For marine fishes with life histories in which adults have limited home ranges and larvae are pelagic and advected vast distances from natal sites, an understanding of variability in larval supply to local populations is critical for understanding the mechanisms that produce dynam...
