“…It is involved in several metabolic processes via alkaline phosphatase, including nucleotide and protein synthesis, energy metabolism, and redox reaction, which can affect substance metabolism, growth, and development in fish 41,42 . In this study, the Zn content was maintained at a high level in all four embryonic stages, indicating that Zn plays vital roles throughout embryonic development in A. schrenckii 43 . Compared to the previous measurement of microelements in skin of farmed A. schrenckii , the contents of Fe and Cu were significantly higher in this study, while Zn was significantly lower 33 .…”

The Amur sturgeon, Acipenser schrenckii, is an important aquaculture species in China with annual production of about 150 thousand tons in 2015. In this study, we investigated the regulatory proteins and pathways affecting embryonic development of Amur sturgeon, by analyzing of the differential proteomes among four embryonic developmental stages using isobaric tags for relative and absolute quantitation (iTRAQ), combined with the analysis of effects of microelements and antioxidants on embryonic development. Seventy-four, 77, and 76 proteins were differentially expressed according to iTRAQ analysis between the fertilized egg and blastula, blastula and neurula, and neurula and heart-beat stages, respectively. GO and KEGG enrichment analyses indicated that Gluconeogenesis, Ribosome and Proteasome were the most enriched pathways, which may promote energy formation, immune system protection and protein synthesis process in A. schrenckii. The measurement of microelements indicated that Mn, Cu and Fe were obtained from their parents or water environment in A. schrenckii, while Zn plays vital roles throughout embryonic development. The dramatically high level of malondialdehyde (MDA) across the embryonic development may be the main reason leading to a low hatching rate in A. schrenckii. This study provides the basis for further proteome analysis of embryonic development in A. schrenckii.

“…Organic minerals are important as trace minerals sources, but due to IP6 complex, they are indigestible and are not hydrolyzed by nonruminants; therefore, phosphorus supplementation is given to avoid its deficiency (Yao et al, 2011;MA et al, 2014). Phytate in vegetable based diet also decreases zinc bioavailability that results in its low digestibility coefficient and low level in the blood and tissues of Atlantic cod (Gadus morhua) and rainbow trout (Oncorhynchus mykiss) (Kousoulaki et al, 2010;Prabhu et al, 2014).…”

Resumo: O fósforo é estocado nas plantas principalmente na forma de ácido fítico (IP6) e representa entre 50 e 80% do fósforo total presente nos ingredientes vegetais. Por ser indigestível pelos animais não ruminantes e permanecer carregado negativamente no pH fisiológico, liga-se a uma grande variedade de nutrientes, principalmente cátions, os quais são eliminados via fezes. Este fato torna necessária a suplementação de fósforo disponível o que aumenta os custos e problemas ambientais. Em vista disso, a fitase tem sido utilizada como forma de degradar a molécula de IP6 e aumentar o aproveitamento do fósforo indisponível. Esta enzima é usada com sucesso na alimentação de aves e suínos, porém controversa para peixes. Como toda enzima, a fitase possui uma faixa de temperatura e pH ótimos para atuar e desnatura quando submetida a extremos. Assim, o processamento da ração (extrusão) e as diversas condições anatômicas e fisiológicas das espécies de peixe desafiam sua integridade e atuação. Em vista disso, entender os principais aspectos envolvidos nos resultados obtidos com o uso da fitase na alimentação de peixes, conduz ao seu uso correto considerando as condições para sua atividade e os desafios impostos tanto pelo processamento quanto pela espécie de peixe. Palavras-chave: Biodisponibilidade, desfitinização, eutrofização, fitato, fósforoAbstract: Phosphorus is stored in plants majorly in the form of phytic acid (IP6), which represents 50-80% of the total phosphorus present in the vegetable ingredients. As it is indigestible by nonruminant animals and remains negatively charged in the physiologic pH, it binds to a large variety of nutrients, mainly cations, which are discarded via feces. This leads to the addition of available phosphorus, which increases the cost and environmental problems. Therefore, the utilization of phytase helps to break IP6 and increases the use of the unavailable phosphorus. Phytase is successfully used in poultry and pigs feeding, whereas for fish, the results are ambiguous. Phytase acts in an optimum range of temperature and pH and denatures when subjected to extremes conditions. Thus, feed processing (extrusion) and the anatomical and physiological conditions of the fish species challenge its molecular integrity and activity. Hence, understanding the main aspects based on the results obtained by the use of phytase in fish feeding leads to optimal utilization of this enzyme due to its ideal activity and the challenges induced by processing and the fish species.

“…Zinc (Zn) is one of the most important essential micronutrients for living organisms, based on its role as an integral constituent of a number of metalloenzymes and as a catalyst for regulating the activity of specific Zn‐dependent enzymes (Antony Jesu Prabhu, Schrama, & Kaushik, ; NRC, ). Dietary Zn supplementation improves growth performance, bone development, immunity and antioxidant activity in aquatic and terrestrial animals (Ao et al, ; Fountoulaki et al, ; Ma et al, ; Wedekind & Lowry, ). Although the requirement of Zn had been investigated in numerous fish species, estimates showed large variations (ranging from 8.6 mg/kg for channel catfish [ Ictalurus punctatus ] to 240 mg/kg for European seabass [ Dicentrarchus labrax ]), which were influenced by several factors such as basal diet type, Zn source, estimation criterion, water salinity and Zn content in the water system (Antony Jesu Prabhu et al, ; Fountoulaki et al, ; NRC, ; Paripatananont & Lovell, ).…”

“…In commercial feeds for common carp, fishmeal and other animal proteins are seldom used and plant proteins supply a major part of the dietary protein. With the replacement of fish meal by plant proteins, an inevitable problem is the introduction of phytic acid that is a strong cation chelator which influences the bioavailability of minerals to animals (Konietzny & Greiner, ; Ma et al, ). However, most studies thus far have not considered the negative effect of phytate in a commercial plant protein‐based diet in common carp.…”

“…Organic Zn, mainly in the forms of metal proteinates, metal amino acid complexes and metal amino acid chelates (Antony Jesu Prabhu et al, ), has been reported to show higher bioavailability than inorganic Zn in chicks (Wedekind, Hortin, & Baker, ), channel catfish (Paripatananont & Lovell, ), rainbow trout ( Oncorhynchus mykiss ) (Apines et al, ) and Pacific white shrimp ( Litopenaeus vannamei ) (Boone) (Lin, Lin, Yang, Li, & Luo, ). However, no significant improvement in Zn bioavailability was demonstrated in studies with chicks (Pimentel, Cook, & Greger, ), turbot ( Scophthalmus maximus ) (Ma et al, ), rainbow trout (Rider, Davies, Jha, Clough, & Sweetman, ), hybrid striped bass ( Morone chrysops × Morone saxatilis ) (Savolainen & Gatlin, ), or even inhibited the growth performance of Nile tilapia ( Oreochromis aureus ) (Do Carmo E Sà, Pezzato, Barros, & De Magalhães Padilha, ) when compared with the inorganic forms. Basal diet type could be one of the most important factors that affected these evaluations.…”

Plant protein‐based diets are widely used for common carp (Cyprinus carpio var. Jian). The plant source antagonist, such as phytate, negatively affects the bioavailability of trace minerals, but this aspect was not considered in previous studies on this species. A 10‐week growth trial was conducted to investigate the effects of inorganic Zinc (ZnSO4·7H2O, Zn‐S) and organic Zn (2‐hydroxy‐4‐(methylthio) butanoic Zinc, Zn‐M) on growth performance, Zn retention and antioxidant responses of common carp (initial weight 10.0 ± 0.03 g). Eleven semi‐purified diets containing 7 mg/kg phytic acid were prepared with 0, 5, 20, 35, 50 and 65 mg/kg Zn from Zn‐S and Zn‐M (12.8 mg/kg Zn in basal level), respectively. The results showed that either Zn‐S or Zn‐M inclusion improved growth performance, vertebral Zn deposition and antioxidant responses of fish. The Zn requirement based on WGR, vertebrae Zn and plasma SOD were 47.0, >77.8 and 48.5 mg/kg, and 63.3, 42.2 and 36.8 mg/kg, respectively, with Zn‐S and Zn‐M as Zn sources. The relative bioavailability of Zn‐M was 2.44‐ (vertebrae Zn deposition) and 1.74‐fold (plasma SOD activity) the availability of Zn‐S in the diet of common carp. The lower growth performance and poor bioavailability in vertebrae of Zn‐S group were related to the chelating of zinc with phytic acid.
