“…Recently, in meta-analytical studies it was observed that the phosphorus requirement estimates as minimal dietary phosphorus levels tend to vary depending on the response criterion and the levels are higher (18-42%) when whole-body or vertebral phosphorus concentration were used as the response criterion than weight gain (Antony Jesu Prabhu et al 2013, 2014. However, in sturgeon (Xu et al 2011) and goldfish (Braga et al 2016) an inverse response was observed contrary to our study.

“…However, in sturgeon (Xu et al 2011) and goldfish (Braga et al 2016) an inverse response was observed contrary to our study. Braga et al (2016), based on bone mineralization, reported a lower phosphorus requirement of goldfish (7.13 g/kg) than that determined on the basis of maximum growth (8.2 g/kg).

“…Similar phosphorus-deficiency signs were also observed in many earlier studies (Ogino and Takeda 1976;Sakamoto and Yone 1978;Takeuchi and Nakazoe 1981;Kim et al 1998;Sukumaran et al 2009;Nwanna et al 2010;Xie et al 2011;Yuan et al 2011;Liang et al 2012;Braga et al 2016). In the present study, improved growth performance and mineralization in the whole body, vertebrae, and scales was recorded in fish fed diets with increasing levels of phosphorus up to 7.8 g/kg, suggesting the essentiality of phosphorus in the diet of fingerling L. rohita.…”

“…Whole-body phosphorus content has been used as a response criterion in many previous studies to estimate the dietary phosphorus requirement (Nwanna et al 2010;Yu et al 2013;Yao et al 2014;Braga et al 2016;Wang et al 2017). In this study, body ash, phosphorus, and calcium contents were found to be significantly influenced in fish fed diets with varying levels of dietary phosphorus.…”

Dietary phosphorus requirement of fingerling Labeo rohita (6.1 ± 0.13 cm; 1.88 ± 0.05 g) was quantified by feeding seven isonitrogenous (350 g/kg crude protein) and isocaloric (16.72 kJ/g gross energy) purified diets with different levels of phosphorus as 3.5 (basal diet), 4.6, 5.7, 6.5, 7.8, 8.9, and 10.1 g/kg. Triplicate groups of fish were fed at 0800, 1200, and 1600 h to apparent satiation for 8 wk. Live weight gain (LWG; 494.68%), specific growth rate (3.18%/d), feed conversion ratio (1.54), feed efficiency (0.65), protein gain (PG; 1.26 g/fish), protein efficiency ratio (1.86), and phosphorus utilization efficiency (98.78%) improved significantly (P < 0.05), with increasing dietary phosphorus level up to 6.5 g/kg. However, phosphorus contents of vertebrae and scale increased significantly up to 7.8 g/kg. Dietary phosphorus levels significantly affected serum phosphorus concentration and alkaline phosphatase activity. Broken‐line analysis based on LWG; PG; and whole‐body, vertebrae, and scale phosphorus against dietary phosphorus indicated the optimal phosphorus requirement of fingerling L. rohita at 6.56, 6.58, 6.56, 8.02, and 8.44 g/kg diet, respectively. In order to restrict superfluous phosphorus in the diet, inclusion of 6.56 g/kg phosphorus is recommended for optimal growth of fingerling L. rohita.

“…These deficiency signs have also been evidenced in some previous reports. (Braga, Araujo, Martins, Oliveira, & Guimaraes, ; Shen et al., ; Wen et al., ; Yao et al., ; Yuan et al., ; Zhang et al., ). Lower levels of dietary phosphorus also cause abnormal bone formation as stated by Roy and Lall (); however, in the present study, this was not observed.…”

A 12‐week feeding trial was conducted to determine the dietary phosphorus requirement of Heteropneustes fossilis fingerlings (7.7 ± 0.04 g). Fish were fed casein–gelatine‐based purified diets in triplicate groups near satiation with seven different levels of dietary phosphorus (3.2, 5.2, 7.2, 9.2, 11.2, 13.2 and 15.2 g/kg dry diet). All diets were formulated to be isoproteic (400 g/kg) and isoenergetic (17.89 kJ/g). Highest absolute weight gain (68.38 g/fish), best feed conversion ratio (1.48), protein retention efficiency (30.74%), protein gain (12.44 g/fish), haemoglobin (11.19 g/dL), RBCs (3.12 x106/mm3), haematocrit (33.44%) and serum phosphate (2.82 mg/L) were found at 9.2 g/kg phosphorus. Hepatic superoxide dismutase and catalase activity were also significantly influenced by the dietary phosphorus levels. Whole body and vertebrae phosphorus concentrations increased significantly as the amount of dietary phosphorus increased from 3.2 to 11.2 g/kg dry diet and then plateaued. More accurate information on dietary phosphorus requirement was obtained by subjecting the AWG, FCR, vertebrae phosphorus and whole body phosphorus concentrations data against various levels of dietary phosphorus to broken‐line analysis, which yielded the requirement in the range of 9.0–11.0 g/kg for optimum growth and mineralization of H. fossilis.

Minerals content of extruded fish feeds containing cricket (Acheta domesticus) and black soldier fly larvae (Hermetia illucens) fractions

Animal food sources provide human beings with minerals considerably in adequate quantities. Fish is an indispensable reliable source of nutrients, as aquaculture is a sector that is fast growing and which provides 50% of the world's fish production. However, fish production is hampered by the increasing costs of feeds due to the ever rising cost of fish meal, an integral component of fish feeds. Substituting fish meal with cheap, yet highly nutritious ingredients in fish feeds is therefore paramount. This study investigated the effects of substituting fish meal with adult cricket meal (ACM) and black soldier fly meal (BSFM) on minerals content of extruded fish feeds, where four levels of substitution (0, 25, 50 and 75%) were used. The effect of feed moisture content on minerals was also studied where 20 and 30% feed moisture levels were used. Leaching effects of the pellets were studied as well. The results showed a significant increase (P \ 0.05) in the levels of phosphorus and potassium as the level of fish meal substitution increased from 0 to 75%. On the other hand, iron and sodium levels reduced significantly (P \ 0.05) as the level of fish meal substitution increased. Magnesium content increased with increasing level of substitution with BSFM, but decreased with increasing level of substitution with ACM. Copper, zinc and manganese were not greatly influenced by levels of fish meal substitution. Diets that had zero substitution showed higher leaching effect for most minerals than diets that were substituted with 75% ACM or BSFM. This study found that both ACM and BSFM can be used to substitute fish meal in fish feeds and obtain adequate mineral profile and low leaching effect.
