One of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. This study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. Trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

—Shortnose sturgeon Acipenser brevirostrum, a U.S. endangered species, has experienced a fourfold increase in abundance in the Hudson River in the past three decades. The age structure and trends in year-class strength of yearlings were investigated to evaluate the underlying pattern of annual recruitment that accompanied population recovery. Annuli in pectoral spine sections were used to estim...

The main purpose of this study in order to estimate fat soluble vitamins contents Mackerel fillets from the northeastern coast of Tunisia. Retinol, α-tocophérol and cholecalciferol were analyzed using HPLC system. The experimental procedure used for extraction consisted on saponification, normal phase separation with UV and fluorescence detection for tocopherol and retinol. While cholecalcifero...

The effect of single-cycle and multiple-cycle high hydrostatic pressure (HHP) treatments on the survival of three Salmonella Enteritidis strains in chicken breast fillets was investigated. The surface of fillets was inoculated with a cocktail of three Salmonella strains at approximately 10(7) colony-forming units (CFU)/g, and held at 4 degrees C for 20 hours before HHP treatments. Reduction of ...

Three poultry chilling methods, namely, water chilling (WC), air chilling (AC), and evaporative air chilling (EAC), were compared to evaluate their effects on broiler breast meat quality and consumer sensory characteristics. A total of 189 birds were processed with 1 of the 3 chilling methods. One-third of the birds were hard scalded (57.7°C, 120 s) and subjected to WC (an ice slurry immersion ...

Abstract Sturgeon and paddlefishes (Acipenseriformes) are cultured worldwide for commercial conservation purposes. Over the past decade, we have learned many sturgeon culture programs experience spontaneous autopolyploidy, or generation of triploidy without management intervention. Spontaneous autopolyploidy has been shown to negatively impact physiology, reproductive development fertility stur...

Weight estimation of whole fish and fillets, skin color fillet meat colors the male female scaled mirror carp (Cyprinus carpio) were evaluated by image analysis. After measuring weight 10 their pictures both sides fish, side fillets taken in a light box. The relationship between (W) view area (V) was calculated linear (W = A + BV), power VB) equations. According to equation B values, carps show...

The micropyle number in the ova of sturgeon species from the South Caspian Sea was investigated. The study was conducted on female broodfishes of three species of sturgeon (Persian sturgeon Acipenser persicus, Stetates sturgeon A. stellatus and great sturgeon Huso huso) included 44 Persian sturgeon, 13 stellate sturgeon and 8 great sturgeon specimens. Fifty eggs were randomly collected from eac...

This study was designed to compare the quality changes in mackerel fillets stored under different conditions by using hyperspectral imaging (HSI) techniques. Fillets packaged vacuum were for six days five conditions: refrigerated at 4℃ (R group); iced 5 ± 3℃ (I kept an ambient of 17 2℃ (A frozen -18℃ 24 h and thawed a refrigerator on sampling day (FTR FTR tap water instead thawing (FTW group). ...
