Examining Movement Dynamics of the Gulf Menhaden Fishery Using an Individual-based Model
… the movement and harvest dynamics of the Gulf Menhaden <em>Brevoortia patronus</em> fishery. The fishery-dependent data collected by NOAA (years 2006-2009 and 2011) describe vessel-specific information on catch locations (latitude and longitude) and magnitude of harvest in metric tons …

Environmentally-Driven Variation in the Population Dynamics of Gulf Menhaden (<i>Brevoortia patronus</i>)
<p>Gulf Menhaden (<em>Brevoortia patronus</em>) is an abundant forage fish distributed throughout the Northern Gulf of Mexico (NGOM). Gulf Menhaden support the second largest fishery, by weight, in the United States and represent a key linkage between upper and lower trophic levels. Variation in …

ESTIMATION OF MORTALITY RATES FOR THE GULF MENHADEN STOCK AND REFERENCE POINT IMPLEMENTATION FOR THE FISHERY
<p>The Gulf menhaden stock is the target of a large commercial fishery in the Gulf of Mexico. To address the needs of both the stock and fishery, I performed two studies. I first addressed the natural mortality rates currently used in the Gulf menhaden stock assessment. To update these rates, I …

Determining the Trophic Role of Gulf Menhaden (<i>Brevoortia patronus</i>) Using Carbon and Nitrogen Stable Isotopes
<p>Gulf menhaden (Brevoortia patronus) play multiple roles in the Gulf of Mexico coastal ecosystem as filter feeders and as an important food source for many recreationally and economically important finfish. Gulf menhaden also support a large commercial fishery, and little is known about the …

Influence of Natural and Anthropogenic Environmental Variability on Larval Fish Diet, Growth, and Condition in the Northcentral Gulf of Mexico
<p>The northern Gulf of Mexico experiences high levels of freshwater runoff annually from various sources including the Mississippi River and Mobile Bay, among other sources. Early life history stages of fishes are especially vulnerable to environmental variability created by freshwater discharge. …

Age, Growth, Reproduction, and Diet of the Finetooth Shark, <i>Carcharhinus isodon</i>, in the Northern Gulf of Mexico
… <em>Carcharhinus isodon</em>, in the northern Gulf of Mexico (nGOM) to provide an accurate description of the species’ reproductive biology, age, growth and diet composition. A total of 1,489 finetooth sharks (830 female; 659 male) were collected from coastal waters of the nGOM between …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
<p>The northern Gulf of Mexico (nGOM) is a diverse and productive region for living marine resources. The region supports lucrative commercial and recreational fisheries ranging from low-trophic-level species, such as penaeid shrimps and forage fishes, to high-trophic-level predators (e.g. …

The effects of life history strategy and uncertainty on a probability-based approach to managing the risk of overfishing
Recent U.S. legislation applies a precautionary approach to setting catch regulations in federal fisheries management. A transparent approach to complying with federal guidelines involves calculating the catch recommendation that corresponds to a specified probability, P*, of exceeding the "true" …
