“…Similar results have also been reported in white shrimp (Pan et al, 2005) and Chinese mitten crab ( Eriocheir sinensis ) (Chen et al, 2014; Lei et al, 2020). Dietary P deficiency may depress the β‐oxidation of fatty acids which was associated with the amount of ATP (Musharraf & Khan, 2018). Some studies on fish and crustaceans suggested that the mRNA expressions of lipid metabolism enzymes were affected by dietary P levels.…”

To evaluate dietary phosphorus requirement of red swamp crayfish (Procambarus clarkia), six diets containing different concentrations phosphorus (2.7, 6.6, 10.5, 14.6, 18.3 and 22.5 g kg−1 diet respectively) were prepared. Each diet was assigned to triplicate of 15 crayfish (initial mean weight: 9.33 ± 0.54 g) for 56 days. The weight gain rate (WGR) significantly increased when dietary phosphorus content increased from 2.7 to 14.6 g kg−1 (p < 0.05), and the feed conversion ratio (FCR) showed an opposite tendency as observed in WGR. As dietary phosphorus level increased, the muscular ash content, the content of calcium and phosphorus in muscle and shell, the inorganic phosphorus concentration in serum, and the protease activities in intestine and hepatopancreas significantly increased (p < 0.05), while the muscular crude lipid content, the lipase activities in intestine and hepatopancreas, the malondialdehyde concentration in hepatopancreas, and the concentrations of total cholesterol, triglyceride and parathyroid hormone in serum significantly decreased (p < 0.05). When crayfish fed diet with phosphorus content from 10.5 to 14.6 g kg−1, the activities of amylase in intestine and hepatopancreas, the activities of catalase in hepatopancreas and the concentration of total antioxidant capacity in hepatopancreas significantly increased (p < 0.05). Broken‐line model analysis in terms of the WGR and FCR indicated that optimal dietary phosphorus requirement of crayfish was from 13.9 to 14.3 g kg−1. The signs of phosphorus deficiency for red swamp crayfish were characterized by poor growth, slightly reduced mineralization and increased body lipid deposition.

“…Phosphorus (P), a required nutrient in fish diet, is a limit factor that causes the deterioration of aquatic environment due to the P discharging from the feed and faeces because of the excessive P supplementation in fish diet (Hua & Bureau, ; Sugiura, Dong, & Hardy, ), whereas P is an essential nutrient required for growth, skeletal mineralization, reproduction and energy metabolism in fish, and is critical to be added into fish diets because fish have the low availability of P in both freshwater and seawater (Lall, ; NRC, ; Roy & Lall, ; Sugiura, Hardy, & Roberts, ). Therefore, to minimize eutrophication of waterbody, aquafeeds should meet the P requirement of fish and avoid excess P contents in the diet at the meantime (Jokinen, Vielma, Aaltonen, & Koskela, ; Musharraf & Khan, ). The studies about P requirement and utilization have been largely reported in many fish species, such as large yellow croaker ( Pseudosciaena crocea R. ) (Mai et al, ), rainbow trout ( Oncorhynchus mykiss ) (Fontagné et al, ; Lellis, Barrows, & Hardy, ), juvenile black seabream ( Sparus macrocephalus ) (Shao et al, ), Africa catfish ( Heterobranchus bidorsalis ) (Nwanna, Adebayo, & Omitoyin, ), stinging catfish ( Heteropneustes fossilis ) (Zafar & Khan, ) and gibel carp ( Carassius auratus gibelio ) (Xie et al, , ), which, however, have rarely been studied in sturgeon.…”

Responses of hybrid sturgeon ( Huso dauricus ♀ × Acipenser schrenckii ♂ ) to oral administration of phosphorus

To better understand the phosphorus (P) utilization in hybrid sturgeon (Huso dauricus ♀ × Acipenser schrenckii ♂), a combined technique with oesophageal intubation, dorsal aorta cannulation and urinary catheterization was used in the present study. Groups of five hybrid sturgeon were orally administrated with graded doses of P (0, 50, 100 and 200 mg P/kg BW) in the form of monocalcium phosphate. The high dose of P (200 mg P/kg BW) caused a significant increase in plasma P concentration. Plasma calcium (Ca) concentrations were significantly increased in the fish treated with 0 and 100 mg P/kg BW. Both P and urea excretion showed increased changing pattern with increasing P intubation level and exhibited significant higher value in 200 mg P/kg BW group. A significant increase in Ca excretion was found in the group without P supplementation (0 mg P/kg BW). ALP and SOD activity in plasma was inhibited in fish at P‐deficient groups (0 and 50 mg P/kg BW). The data in the current study showed that hybrid sturgeon at 100 mg P/kg BW treatment exhibited better P and Ca utilizations with lower waste excretion, as well as favourable status of anti‐oxidation.

“…When phosphorus levels in the ration are excessive, the efficiency of its use decreases considerably, increasing its excretion into the environment and contributing to the eutrophication of the aquatic environment. Because of this, it is necessary to adjust the dietary concentration of the element to strictly meet, but not exceed, nutritional requirements (FURUYA et al, 2010;TANG et al, 2012;MUSHARRAF;KHAN, 2019).…”

“…An increase in weight gain was observed until the estimated digestible phosphorus level reached 0.64%, associated with consumption of similar feed and a linear increase in phosphorus consumption, implying an improvement of feed:gain ratio. This indicates that increased phosphorus in the diet promoted an improvement in the use of nutrients, especially for protein deposition, as lean tissue deposition (protein) is more energy efficient than fat deposition because protein incorporates more water in its composition (NOBLET et al, 2001;BOMFIM et al, 2010;SOUSA et al, 2018;MUSHARRAF;KHAN, 2019), thus minimizing the excretion of nitrogenous residues to the environment (BOMFIM 2013).…”

The objective of this study was to determine the digestible phosphorus requirement in rations for tambaqui fingerlings (Colossoma macropomum). 900 fingerlings (0.51 ± 0.06 g) were used in a completely randomized design with six treatments, five replicates, and thirty fish per experimental unit. The treatments consisted of six diets with different digestible phosphorus levels (0.12, 0.33, 0.54, 0.75, 0.95, and 1.16%). The fish were fed six times a day, for 63 days. Performance, feed efficiency, and the daily protein, fat, ash, and phosphorus deposition rates of fish were evaluated. The treatments did not influence the feed intake. The elevation of phosphorus levels increased the digestible phosphorus intake linearly, and improved of quadratic form the weight gain, specific growth rate, feed:gain ratio, protein efficiency for weight gain, and daily protein, fat, ash, and phosphorus depositions up to the estimated levels of 0.64, 0.66, 0.70, 0.70, 0.62, 0.62, 0.70, 0.71%, respectively. The phosphorus efficiency for weight gain worsened with the elevation of phosphorus levels. The recommendation of digestible phosphorus level in rations for tambaqui fingerlings to optimize weight gain and body phosphorus deposition is 0.71%, which corresponds to the estimated level of 1.04% total phosphorus.
