“…Advanced degradation is signified by an increase in aldehyde concentrations, the byproduct of the oxidation of peroxides (German and Kinsella, 1985).Higher aldehyde concentrations in summer harvested fish suggests that these fish experienced greater perimortem stress and poorer shelf life as a result. This is consistent with the observations of Trushenski and Kohler (2007), in which preslaughter stress was observed to increase fillet aldehyde concentrations after short-term frozen storage in Hybrid Striped Bass (Morone chrysops♀ x M. saxatilis♂). 8 www.…”

Exportation of Asian carp from the Illinois River to China is an emerging business with ecological and economic benefits. The current market environment supports the shipment of frozen Asian carp to China; however, lack of standardization in harvesting, hauling, and processing techniques present challenges for product quality. The objective of this study was to evaluate seasonal, spatial, and species effects on fillet quality of Asian carp harvested from the Illinois River. As such, Bighead and Silver Carp were harvested on two occasions (summer and fall) from two geographically distinct reaches (Alton and Peoria) of the Illinois River. Lower (P<0.05) fillet pH, Torrymeter freshness values, and higher aldehyde concentrations were observed in fillet coming from fish harvested in summer compared to those harvested in fall. Asian carp caught in the Alton Reach had lower (P<0.05) fillet pH, post-processing freshness values, and higher aldehyde concentrations than those from the Peoria Reach. Summer harvested fish had higher (P<0.05) whiteness values than fall harvested fish. Lower (P<0.05) pH, freshness values, and increased peroxide concentrations were observed in Bighead Carp relative to Silver Carp fillets.This is the first report of color and Torrymeter freshness values for Silver and Bighead Carp. This can establish a reference for future research in commercial evaluation of flesh quality for these two species.Indicators of shelf life suggest improved product quality for a frozen fish export market can be achieved by concentrating harvest on Silver Carp in the Peoria Reach during the fall season.

“…Vitamin E is indispensable for crustacean and plays critical roles in a variety of biochemical and physiological processes, such as protecting biological membranes, lipoproteins and oxidation of polyunsaturated fatty acids (PUFA) (Hamre, 2011). The positive effects of vitamin E on growth performance (Kocabas & Gatlin, 1999) and immune response (Trichet, 2010;Trushenski & Kohler, 2007) have been reported in various vertebrate species. Sufficient vitamin E can improve growth performance and tolerate blood oxidative stress in the red seabream fed oxidized fish oil due to the protection of vitamin E against lipid oxidation (Gao et al, 2012).…”

Effect of dietary lipid source and vitamin E on growth, non-specific immune response and resistance to Aeromonas hydrophila challenge of Chinese mitten crab Eriocheir sinensis

et al. 2018

Six purified diets were formulated to contain three lipid sources, fish oil (FO), linseed oil (LO) and soybean oil (SO), at 6% diet lipid crossing two levels of vitamin E (100 and 300 mg α‐tocopheryl acetate/kg diet) for each lipid source (FO100, FO300, LO100, LO300, SO100, SO300). The juvenile Chinese mitten crab, Eriocheir sinensis, respectively, fed on these diets with four replicates for 6 weeks. The crab weight gain (WG) and specific growth rate (SGR) were significantly affected by dietary lipid sources. No difference was found between the crabs fed two levels of vitamin E, but the WG and SGR were numerically higher in crab fed 300 mg/kg vitamin E than those fed the other level of vitamin E. The lipid source and vitamin E level could affect fatty acid composition in the hepatopancreas. The contents of saturated fatty acids (SAFA) and n‐3HUFA were significantly higher in the crab‐fed fish oil. The highest contents of n‐6PUFA and n‐3PUFA were found in the crab‐fed soybean oil and linseed oil respectively. The contents of SAFA, n‐3HUFA and n‐3PUFA were higher in the 300 mg/kg vitamin E treatment. A lower malondialdehyde (MDA) content and higher phenoloxidase (PO) activity were observed in the crab fed 300 mg/kg vitamin E. The results of this study indicate that the Chinese mitten crab fed the diet with 6% fish oil and 300 mg/kg vitamin E showed better growth, antioxidant capacity and resistance to Aeromonas hydrophila.

“…It plays important roles in various biochemical and physiological processes, including serving as an antioxidant as well as in signal transduction (reviewed by Brigelius-Flohe´et al 2002;Fang et al 2002). In nutrition and physiological research with various aquatic species, vitamin E supplementation has been shown to improve growth performance (Kocabas & Gatlin 1999), enhance immunity (Sealey & Gatlin 2002;Puangkaew et al 2004;Trushenski & Kohler 2007) and restore impaired immunity (Montero et al 1998;Sahoo & Mukherjee 2002), as well as influence neuroendocrine function and reproduction under environmental toxicity (Khan & Thomas 2004). Therefore, vitamin E is an essential micronutrient that may have very important applications for both stock enhancement and commercial/ food fish aquaculture of red drum.…”

“…Numerous studies have shown that dietary vitamin E can influence immune responses of fish including hybrid striped bass (Sealey & Gatlin 2002;Trushenski & Kohler 2007), gilthead sea bream (Sparus Aurata) (Montero et al 1998); grouper (Epinephelus malabaricus) (Lin & Shiau 2005) and carp, Labeo rohita (Hamilton) (Sahoo & Mukherjee 2002). Vitamin E supplementation also has been shown to enhance respiratory burst of fish macrophages (Blazer 1991;Sealey & Gatlin 2002).…”

A 12‐week feeding trial was conducted to establish the minimum dietary vitamin E requirement of juvenile red drum by broken‐line regression analysis. The semi‐purified basal diet was supplemented with 10, 20, 30, 40, 60 or 80 IU vitamin E kg−1 as all‐rac‐α‐tocopheryl acetate. Juvenile red drum were conditioned by feeding the basal diet for 8 weeks prior to the feeding trial to reduce whole‐body vitamin E levels. Then, fish initially averaging 12.2 ± 0.4 g fish−1 (mean ± SD) were fed the experimental diets at a rate approaching apparent satiation for 12 weeks. Weight gain and feed efficiency responses of fish fed diets were significantly (P < 0.01) altered by the level of vitamin E supplementation but not strictly in a dose‐dependent manner. Vitamin E concentrations in liver and plasma also were significantly (P < 0.001) influenced by dietary vitamin E level. Plasma ascorbic acid in fish fed the basal diet tended (P = 0.066) to be lower than in fish fed diets containing the various levels of vitamin E. In addition, fish fed the basal diet showed edema in the heart, while fish fed all other diets were normal. Fish fed 60 or 80 IU all‐rac‐α‐tocopheryl acetate kg−1 diet had significantly higher respiratory burst of head kidney macrophages than fish fed all other diets, although dietary effects on hematocrit and neutrophil oxidative radical production were not significant. The minimum dietary vitamin E requirement of juvenile red drum was established based on broken‐line regression of liver thiobarbituric acid reactive substances to be 31 mg all‐rac‐α‐tocopheryl acetate kg−1 diet.
