“…Nevertheless, a linear increase of iron concentration was observed for whole-body samples. In a similar fashion, a linear increasing relationship was found between the whole-body iron concentration and increased ferrous sulphate concentrations in the feed when offered to the stinging catfish (Heteropneustes fossilis) (Zafar & Khan, 2020) and Indian major carp (Labeo rohita) (Musharraf & Khan, 2019). For teleost fish, it is postulated that dietary iron is likely either stored in the liver or utilized during erythropoiesis, as suggested previously (Bury et al, 2012).…”

To prevent catfish idiopathic anaemia, diets fortified with iron have been adopted as a regular practice on commercial catfish farms to promote erythropoiesis. However, the effects of prolonged exposure of excess dietary iron on production performance and disease resistance for hybrid catfish (Ictalurus punctatus × I. furcatus) remains unknown. Four experimental diets were supplemented with ferrous monosulphate to provide 0, 500, 1000, and 1500 mg of iron per kg of diet. Groups of 16 hybrid catfish juveniles (~22.4 g) were stocked in each of 20, 110‐L aquaria (n = 5), and experimental diets were offered to the fish to apparent satiation for 12 weeks. At the end of the study, production performance, survival, condition indices, as well as protein and iron retention were unaffected by the dietary treatments. Blood haematocrit and the iron concentration in the whole‐body presented a linear increase with the increasing the dietary iron. The remaining fish from the feeding trial was challenged with Edwardsiella ictaluri. Mortality was mainly observed for the dietary groups treated with iron supplemented diets. The results for this study suggest that iron supplementation beyond the required levels does affect the blood production, and it may increase their susceptibility to E. ictaluri infection.

“…Due to higher bioavailability compared to inorganic salts, chelated minerals as feed supplements have beneficial effects on growth performance or immunity for animal (Apines-Amar et al, 2004;Manangi, Vazques-Añon, Richards, Carter, & Knight, 2015;Sarker, Satoh, & Kiron, 2007). Dietary iron levels significantly influenced whole body moisture, protein, and lipid content (Musharraf & Khan, 2019). We speculated that the crude protein in loach meat increased because Fe (II)-HPH was used as additive to supplement amino acids in feed (Eckert et al, 2016) and the increase in whole body protein also may be because of the availability of optimal amount of iron activating the protein metabolism resulting into improved protein retention and fish growth (Musharraf & Khan, 2019).…”

To study the effect on amino acid and mineral content of the loach meat by adding Fe (II) chelating hairtail protein hydrolysates (Fe (II)‐HPH) to the feed. A total of 100 healthy loaches were selected. After 1 week's adaptive feeding, they were randomly divided into five groups and fed with feeds containing of Fe (II)‐HPH (0, 0.5, 1, 2, and 4 g/kg). On the 40th day, detection work of general nutrients (moisture, ash, crude protein, and crude fat), mineral elements (Fe, Mn, Cu, Zn, Na, K, and Ca), amino acid and amino acid score (AAS), Chemical Score (CS) and essential amino acid index (EAAI) indexes were done. The results show that crude protein has the highest content while crude fat has the lowest when amount of added Fe (II)‐HPH in feed is 2 g/kg. The Fe content is significantly improved while amount of added is 1, 2, 4 g/kg. The Ca content is significantly improved and the Zn content is significantly improved while amount of added was 2 g/kg. Mn contents are significantly lower than control while amount of added is 4 g/kg. Based on analysis of amino acids in each group, the nutritional value of loach meat with 2 g/kg Fe (II)‐HPH addition amount is relatively high, total amount of essential amino acids increases significantly, and EAA/TAA and EAA/NEAA improve significantly. In conclusion, adding 2 g/kg Fe (II)‐HPH to feed could improve the nutritional values of loach meat.

“…The AMBI and M-AMBI indices were used to evaluate the environmental ecological quality of the Shenzhen Bay intertidal zone, and various biological indices and fouling biological communities were used to evaluate the water quality. Summarizing the analysis of the improvement and application of biological index in China, due to the late start, data shortage and many other factors, it lags behind foreign countries [10]. At present, the Shannon-Wiener diversity index evaluation is the usual method for analyzing the environmental effects of marine benthic communities in my country.…”

Sansha Bay is one of the most typical aquaculture bays in the East China Sea. It is of great significance to study the benthic environment effects of aquaculture activities in Sansha Bay. At present, the overall number of studies in this area is relatively small. In order to study the benthic environmental effects of aquaculture activities in Sansha Bay, different scholars have tried to explain the ecological effects of aquaculture activities from different perspectives. The purpose of this paper is to study the benthic environmental effects of aquaculture activities in Sansha Bay based on different biological indices. In the experiment, the Shannon-Wiener diversity index and AMBI biological index calculation formula are used to analyze and investigate the environmental quality. The experimental results show that the results of AMBI and BAMBI in Sanshawan are similar. The average value of AMBI in Sanshawan is 3.41, while that of BAMBI is 3.38. The average value of BAMBI index is lower than that of AMBI index, and both of them are rated as good environmental quality.
