Maturation Spawning and Larviculture of Atlantic Croaker (Micropogonias undulatus) at Low Salinity
<p>Atlantic Croaker is a popular baitfish among anglers targeting a variety of gamefish in the Gulf of Mexico. Aquaculture of this species could help meet the demand for Croaker, especially during winter when wild-caught Croaker are unavailable. Currently, Croaker aquaculture involves broodstock …

Bioenergetic and ecological consequences of diet variability in Atlantic croaker Micropogonias undulatus
Atlantic croaker Micropogonias undulatus is a commercially and ecologically important bottom-associated fish that occurs in marine and estuarine systems from Cape Cod, MA to Mexico. I documented the temporal and spatial variability in the diet of Atlantic croaker in Chesapeake Bay and found that in …

Clostridium botulinum toxin development in refrigerated reduced oxygen packaged Atlantic croaker (Micropogonias undulatus)
… botulinum in refrigerated raw vacuum packaged croaker fillets, and to determine if toxin development precedes microbiological and/or organoleptic spoilage. Raw croaker fillets were vacuum packaged in oxygen-permeable films (OTR of 10,000 cc/m2/24hr or 3,000 cc/m2/24hr) and stored at either 4ºC …

Global Conservation Status of Croaker and Drum (Family: Sciaenidae) and Role of the Maw Trade
<p>Understanding threats and drivers of extinction risk is critical to conserving marine biodiversity. Although marine bony fishes are some of the most diverse and abundant vertebrates in the world, overexploitation is the major threat to these taxa. Species in the family Sciaenidae are important …

Modeling the effects of endocrine disrupting chemicals on Atlantic croaker: understanding biomarkers and predicting population responses
… that uses a series of models, based on Atlantic croaker, to extrapolate laboratory results to indicators of individual and population health. First, I created a physiologically based model that simulates vitellogenesis in a female fish. The model simulates the major biochemical reactions from the …

Investigations of the Trophic Relationships, Feeding Ecology and Feeding Behavior of Larval Spot, <i>Leiostomus Xanthurus</i> Lacepede, and Atlantic Croaker, <i>Micropogonias Undulatus</i> (Linnaeus) (Pisces:Sciaenidae)
… spot (Leiostomus xanthurus) and Atlantic croaker (Micropogonias undulatus) larvae was evaluated and compared. Nutritional condition of spot larvae from the Gulf of Mexico was high, with no larvae classified as starving. This was probably due to an inability to sample starving larvae at sea …

Assessing Movement of Fish Through Spectral Analysis of Otolith Life History Scans
… fish. Sagittal otoliths from juvenile Atlantic croaker (<em>Micropogonias undulates</em>) and adult black sea bass (<em>Centropristis striata</em>) were sampled using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS).</p> <p>For Atlantic croaker, spectral analyses of the …

INTERANNUAL VARIABILITY IN MORPHOMETRIC CONDITION OF LARVAL FISH AS A FUNCTION OF ENVIRONMENTAL VARIABLES IN BEAUFORT, NC
… among four North Carolinian fishes: Atlantic Croaker (Micropogonias undulatus), Mojarra (Eucinostomus sp.), White Mullet (Mugil curema), and Broad Striped Anchovy (Anchoa hepsetus). All species had some aspect of their morphometric condition influenced by an environmental or ecological …

Investigating Nekton Response to Changing Salinities in the Mississippi Sound: An Experimental and Statistical Approach
… influence the abundance of blue crab, Atlantic croaker, bay anchovy, and brown and white shrimp. Results varied by species, with some likely benefiting from prolonged freshenings and others exhibiting more complex relationships with salinity and temperature, indicating a need to better …

Diet Analysis of Stranded Bottlenose Dolphins (<i>Tursiops truncatus</i>) in Virginia
… fishes dominated the diet, especially Atlantic croaker, spot, and seatrout spp., adding evidence to the theory that bottlenose dolphins passively listen for their prey. Noise pollution should be an important consideration for the conservation of this species. The diet was influenced by …

An improved mixed-error non-equilibrium stock-production model and its application to some Brazilian fish stocks
… for contradictory outcomes. For whitemouth croaker, the balance between process and observation error could not be consistently achieved, because of high amount of observation noises. For grey triggerfish, the assessment revealed a collapsed stock, but previous biological studies do not …

Striped Bass and Summer Flounder Population Dynamics in the Chesapeake Bay: an Ecosystem Based Evaluation
… of summer flounder, weakfish, spot, and Atlantic croaker were the main species that contributed to the difference in community structure after 2011. The change in functional group structure after 2011 was defined by a decline in opportunistic demersal fish, and this change was significantly …

Analyses of Indices of Abundance for Important Groundfish Species in the Northern Gulf of Mexico from 1987-2009, Relative to Shrimp Bycatch; with Age and Growth of Three Sciaenid Species
<p>Bycatch in the shrimp fishery became of particular concern in the 1980s during the peak of shrimp harvest in the northern Gulf of Mexico. Shrimp bycatch is of major importance because the majority of catch in the fishery is not intended target species of commercial shrimp, and most of the …
