123 Citations | This study confirmed that in terms of both quantity and quality, fish products in the Polish market could serve as a significant source of essential amino acids and that the sulphur-containing essential amino acids and lysine present in fish products could supplement the corresponding deficiency in plant proteins. |
41 Citations | Mussel, squid, crustaceans and fish showed a high essential amino acid index according to Oser (OI: 88–99 %) suggesting a suitable amino acid balance. |
It should be emphasized that fish oils do contain other pharmacologically active ingredients apart from EPA. | |
01 May 1999 | The dietary requirement of these farmed fish for high-quality protein, rich in essential amino acids, can be met by sources other than fishmeal. |
148 Citations | The amino acid composition showed that oilseeds contained nutritional useful quantities of essential amino acids. |
12 Citations | TTA and fish oil may influence amino acid metabolism through different metabolic mechanisms. |
Furthermore, it is noteworthy on the nutritional point of view that the content of essential amino acids of the cuttle-fish muscle protein are almost same as those of the fish. | |
26 Citations | Our analysis indicates that, when supplemented with additional fish oils and essential amino acids, fish skin is a viable alternative for fish meal formulations. |
17 Citations | In conclusion, up to 50% protein-bound amino acids can be replaced by crystalline amino acids in diets for Senegalese sole juveniles without negative effects in fish performance. |

Amino acid anabolism in fish5 answersAmino acid anabolism in fish is a complex process that involves the synthesis and metabolism of various amino acids. Fish have limited ability in endogenous biosynthesis of arginine, an essential amino acid that plays a role in nutrient metabolism, insulin release, immune responses, and disease resistance. Glutamate and glutamine, which are synthesized de novo from other amino acids and ammonia, are important metabolic fuels for fish tissues and have roles in protein synthesis, glutathione synthesis, and anti-oxidative reactions. Amino acid metabolism in fish involves interorgan fluxes and interactions between organs such as the intestine, liver, kidney, and skeletal muscle. Dietary amino acid imbalances can lead to increased amino acid oxidation and decreased food conversion efficiency in fish larvae. Some amino acids and their metabolites, such as taurine, glutamine, glycine, proline, and hydroxyproline, have been found to promote growth, development, and health in fish, challenging conventional definitions of essential and nonessential amino acids.
Does fish oil contain vitamin A?5 answersFish oil is a rich source of vitamins A, D, and E, as well as polyunsaturated fatty acids (PUFA) such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). It is known to contain fat-soluble vitamins, including vitamin A. The role of vitamin A in fish oil is important for visual development in fetuses and infants. The extraction of fish oil for human consumption has been fostered by increasing consumer awareness of its nutritional richness. Additionally, during World War II, Australia developed a flourishing industry that derived vitamin A-rich oil from the livers of sharks, meeting domestic and military needs for this nutritional supplement. Therefore, fish oil does contain vitamin A, making it a valuable source of this essential nutrient.
What is fish amino acid?2 answersFish amino acids are important biomolecules that serve as building blocks for proteins and regulate key metabolic pathways in fish. They are essential for energy production, growth, protein synthesis, and various physiological processes. Functional amino acids, which are involved in cellular processes apart from protein synthesis, have gained increased interest in recent years for their potential to improve fish health and welfare. Some of the most studied functional amino acids in fish include arginine, glutamine, glutamate, tryptophan, sulfur amino acids (methionine, cysteine, and taurine), histidine, and branched chain amino acids. These amino acids have been found to play roles in disease resistance, immune response, reproduction, behavior, and more. The amino acid composition of different fish species varies, with cold water species being rich in lysine and aspartic acid, marine fishes in leucine, small indigenous fishes in histidine, and carps and catfishes in glutamic acid and glycine.
