“…Estimations of EAA requirements in fish have also been made based on the composition of the body tissues relative to ratios of key amino acids to lysine (Glencross, 2006). However, balancing EAA Lys −1 is more effectively reached through the dietary supplementation of crystalline amino acids (Nunes et al, 2014).…”

-This study investigated the effect of dietary amino acid composition from proteins alternative to fishmeal on the growth performance of the common snook, Centropomus undecimalis. ) and achieved the lowest body weight (31.1±6.62 and 33.3±10.20 vs 40.4±13.18 g) and the highest feed conversion ratio (3.69±0.29 and 3.11±0.51 vs 2.33±0.34) when fed SPC and basal diets compared with PBM, respectively. Retention of dietary crude protein varied from 36 to 38% for fish fed the basal and SPC diets, but exceeded 51% in fish fed PBM. Results indicate a greater ability of the common snook to gain weight and increase retention of nutrients when dietary protein is of terrestrial animal origin. Dietary protein from PBM yields a more balanced dietary amino acid composition relative to fish muscle, but possibly in excess of the species requirements.

“…Feed Conversion Ratio (FCR) is defined as the amount of dry feed required to produce one kg of wet fish [41]. In agreement [41], who also defined FCR as the amount of food fish are able to convert into body mass and determine aquaponic system nutrient release over time.…”

“…In agreement [41], who also defined FCR as the amount of food fish are able to convert into body mass and determine aquaponic system nutrient release over time. On average, fish are generally kept at 1 kg per 100 L tank which is equivalent to 10 kg/1000 L, this is a low stocking density, and this will convert to support approximately 20 lettuce plants in the hydroponic culture [24].…”

“…However, Barramundi and Murray cod fish species have been raised in recirculating aquaponic systems in Australia [7]. It is confirmed by various literatures, including over 25 years of research by James Rakocy at UVI that tilapias are the most farmed fish species [41]. Tilapia has been combined with most vegetables from the list including lettuce, cucumber, tomatoes, herbs and most of the other leafy and fruity vegetables, and has both performed outstandingly well in most cases [2].…”

“…The destruction of O 3 is catalyzed by NO, halogens, hydroxyl, and hydrogen [22]. A possible source of NO is from N 2 O, the product of denitrification, which can diffuse into the upper atmosphere and lead to atmospheric holes, hence causing problems for plants and animal life well-being from excessive exposure to ultraviolet fish in the world [41,46]. Tilapia produces a white-fleshed meat rich in protein suitable to local and wholesale markets for easy availability and accessibility [1].…”

Gastrointestinal methionine shuttle: Priority handling of precious goods

et al. 2016

Methionine (Met) is a neutral, sulfur-containing, essential amino acid with biological functions in the initiation and prolongation step of protein synthesis, transmethylation reactions, the synthesis of cysteine and cystine, and as a component of antioxidant systems. Its key importance is reflected by the fact that it is usually absorbed from the diet with highest efficiency among all proteinogenic amino acids but may yet not optimally support metabolism and health. As such, crystalline Met supplements are partly used in man and heavily used in production of animal species (poultry, fish, shrimps, pigs and cattle) to provide improved health and performance. The main intention of this review is to analyze the current knowledge on transport proteins with proven or hypothetical relevance for Met absorption in the gastrointestinal tract, especially the small intestine. These transporters include Na -dependent B AT1 and ATB and the Na -independent exchanger b /rBAT in the apical membrane, which may be supported by the Na -dependent systems ASCT2 and IMINO. The basolateral exit of Met appears to be largely limited to a single uniporter protein, LAT4. Insufficient or overtaxed efflux via LAT4 may lead to significant intracellular accumulation and metabolism of Met in the absorptive state. The latter can release large amounts of homocysteine into the blood, which favors atherosclerosis and other cardiovascular, as well as neurological, diseases. When LAT4 is defective, basolateral Met exit may be compensated to a certain degree by the Met exchange proteins 4F2hc/LAT2 or 4F2hc/LAT1; while carriers 4F2hc/y LAT1, 4F2hc/y LAT2, SNAT1 and SNAT2, may serve primarily for basolateral Met import. Expression of SNAT2 is increased when amino acid supply from the lumen ceases, suggesting a key role for Met supply of enterocytes in interdigestive periods. Enterocytes themselves have a huge requirement for Met to synthesize mucins and glutathione. © 2016 IUBMB Life, 68(12):924-934, 2016.
