Oxidative stability of Menhaden/Soybean oil blends
With the approval of menhaden oil pending, the food industry is trying to incorporate marine oils high in omega-3 fatty acids into food systems. The main problem obstructing its use as a food ingredient is fishy/painty flavors which occur with low levels of oxidation. The purpose of this study was …

Lipoxygenase activity in menhaden (Brevoortia tyrannus) and its contribution to oxidation of omega-3 polyunsaturated fatty acids in menhaden oil
Menhaden is the major source of fish oil in the United States. Due to a high amount of polyunsaturated fatty acids which are highly susceptible to autoxidation, menhaden oil deteriorates rapidly, leading to objectionable off-odors and off-flavors. The purpose of this study was to investigate if the …

Menhaden (Brevoortia tyrannus): utilization as a potential food resource
Thermally processed menhaden products were evaluated as potential food products. Nine canned menhaden products judged to be satisfactory in pilot studies were canned or pasteurized and evaluated by a six member semi—trained panel. Panelists scored product characteristics of menhaden products and …

Effects of Natural Antioxidants on Lipid Oxidation of Menhaden Oil
… the activity of novel antioxidants in menhaden oil and to develop optimum formulations containing mixed tocopherols to control oxidation of menhaden oil. Alpha tocopherol, gamma tocopherol, and delta tocopherol in menhaden oil were found at 0.18mg/g, 0.37mg/g, and 0.14mg/g, …

Promoting of soybean oil oxidation by the addition of menhaden oil
… determine if a small amount (0.5%) of deodorized menhaden oil (DMO) Significantly promotes or accelerates the oxidation of soybean oil (SO). A blend (M/S) of 0.5% DMO in commercial SO, pure SO, DMO and undeodorized menhaden oil (UDMO) were stored in the dark for ten weeks at 30°C. A control or "on …

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 (mt). A …

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 …

Growth of Age-0 Atlantic menhaden (BREVOORTIA TYRANNUS) in Two Tidal Freshwater Tributaries of Chesapeake Bay
… have described growth rates of age-0 Atlantic menhaden (Brevoortia tyrannus). Growth rates from tidal freshwater habitats of the Mattaponi and James Rivers, Virginia in 2009 were described and compared using otolith microstructural analyses. Larval tidal freshwater growth rates were …

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 …

Polycyclic Aromatic Hydrocarbon determination in liver of Menhaden exposed to the Deep Water Horizon Oil Spill
… </em>are filter feeding fish commonly known as menhaden and account for over 40% of the commercial industry fisheries catch. As primary consumers, they are a major link in the food chain. In this study, liver metabolites of PAHs were measured in menhaden using fixed emission fluorescence …

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 …

The Impact of Multiple Nursery Areas on the Population Structure of Atlantic Menhaden, <i>Brevooria tyrannus</i>
… increasingly changing environment. The Atlantic Menhaden <em>Brevoortia tyrannus</em> is a clupeid that plays a critical role in the marine food web and supports one of the largest fisheries on the US East Coast. In addition to a decrease in overall numbers and spawning stock biomass, recruitment …

Influence of environmental conditions on the age, hatch dates, and growth of juvenile Atlantic menhaden in the Choptank River, MD
Since 1993 Atlantic menhaden has experienced sustained low juvenile production (recruitment) in the Chesapeake Bay. Factors controlling growth, abundance, and mortality of larval and juvenile menhaden change throughout ontogeny such that larval growth rates could carry over to juvenile growth and …

Detection of PAHs in Commercial and Wild Caught Fish Oil using Scanning Fluorescence Spectroscopy
… The purpose of this project was to develop menhaden fish oil as a biomonitoring tool for crude oil contaminants such as PAHs using scanning fluorescence spectroscopy (SFS). Menhaden (Genus <em>Brevoortia</em>) is one of the most ecologically and economically important marine fish species …

Effects of Maternal Dietary Fats and Antioxidants on Growth Rate and Bone Development of Commercial Broilers
… either 3% chicken fat (CF), soybean oil (SBO) or menhaden oil (MO). Each diet was provided with or without the antioxidant ethoxyquin, producing a total of six dietary treatments. Addition of fats [soybean (SBO), menhaden oil (MO), chicken fat (CF), soybean + antioxidant (SA), menhaden + …

Immunomodulation by dietary lipids: soybean oil, menhaden fish oil, chicken fat, and hydrogenated soybean oil in Japanese quail (Coturnix coturnix japonica) and Bobwhite quail (Colinus virginianus)
Soybean oil (SBO), menhaden fish oil (FO), chicken fat (CF) or hydrogenated soybean oil (HSBO) were incorporated at 5% of the total diet to study changes in the immunological status of both Japanese quail (JAP) and Bobwhite quail (BOB). The SBO diet, in which 66% of the total fatty acids were …

IMPROVING LARVAL SUNSHINE BASS PRODUCTION THROUGH SUPPLEMENTATION OF FEMALE WHITE BASS BROODSTOCK DIETS WITH LONG-CHAIN POLYUNSATURATED FATTY ACIDS
… sources. Of the marine and plant oils tested, menhaden fish oil provided female white bass broodstock the fatty acids (~3.9% n-3 long-chain polyunsaturated fatty acids; LC-PUFA; dry matter basis) necessary to maximize embryonic survival; however, flax oil, due to its low 18:2n-6 and high …
