ronchus y Micropogonias undulatus
. El numero de especies vario de 37 (74 %) en 2005, 33 (66 %) en 2006 y 32 (64 %) en 2007-2008.
The survey targets Atlantic croaker (Micropogonias undulatus
), Atlantic menhaden (Brevoortia tyrannus), southern flounder (Paralichthys lethostigma), spot (Leiostomus xanthurus), summer flounder (P.
Studies carried out with Micropogonias undulatus
(Trant & Thomas, 1989), Cynoscion nebulosus (Thomas & Trant, 1989) and Halobatrachus didactylus (Modesto & Canario, 2002) have shown that 17,20[beta],21-trihydroxy-4-pregnen-3-one (17,20[beta],21P) act as MIS instead of 17[alpha],20[beta]-DP.
The most abundant organisms in marsh habitat included grass shrimp (Palaemonetes spp.), Atlantic croaker (Micropogonias undulatus
), and red drum Sciaenops ocellatus).
The Atlantic croaker (Micropogonias undulatus
) looks for all the world like a small redfish with a lighter coloring.
(43) found that Atlantic croaker (Micropogonias undulatus
) also recruited to specific habitats.
These included: Atlantic croaker, Micropogonias undulatus
; black drum, Pogonias cromis; cobia, Rachycentron canadum; king mackerel, Scomberomorus cavalla; lane snapper, Lutjanus synagris; longspine porgy, Stenotomus caprinus; red drum, Sciaenops ocellatus; seatrout, Cynoscion spp.; other snapper, Lutjanus spp.; grouped sharks, Order Selachii; southern flounder, Paralichthys lethostigma; spotted seatrout, Cynoscion nebulosus; Spanish mackerel, Scomberomorus maculatus; and vermilion snapper, Rhomboplites aurorubens.
Abstract.--Spatial and temporal variation in feeding of immature stages (10-130 mm standard length) of two sciaenids, spot (Leiostomus xanthurus) and Atlantic croaker (Micropogonias undulatus
), was investigated at Mad Island Marsh on the Texas Gulf coast from March 1998 through August 1999.
Maturity, spawning, and ovarian cycle of Atlantic croaker, Micropogonias undulatus
, in the Chesapeake Bay and adjacent coastal waters.
In order to ascertain if these patterns may be influenced by food availability, an analysis of the stomach fullness and prey item composition and abundance of three dominant sciaenid species (Bairdiella chrysoura, Cynoscion regalis, Micropogonias undulatus
, total stomachs n = 312) was conducted along eight locations across a sand ridge.
Other predators include clearnosed skate Raja eglanteria, Atlantic croaker Micropogonias undulatus
, windowpane flounder Scophthalamus aquosus, and spot Leiostomus xanthurus (Bowman et al., 2000).
Peter Thomas and his colleagues at the University of Texas Marine Science Institute in Port Aransas have now shown that some Atlantic croakers (Micropogonias undulatus
) in the Gulf of Mexico have underdeveloped sperm and eggs.
