“…Still, some plant protein ingredients have been described as feasible alternatives for partial replacement of fishmeal in diets for aquaculture. Our previous experiments indicate that an adequate combination of alternative plant low-phosphorus protein ingredients, mainly soybean meal, significantly reduces the phosphorus loading from rainbow trout diets without compromising the growth Hernandez et al 2004).…”

ABSTRACT:The study was conducted to compare two plant ingredients as dietary protein sources for rainbow trout on the basis of feed acceptability, survival, growth, feed conversion, nitrogen and phosphorus utilization efficiency and loading. Two extruded diets were formulated with the inclusion of a soybean meal (DS) and a lupin meal (DL). The control diet was a fish meal (FM) based diet. All diets were isonitrogenous and isolipidic. Triplicate groups of 65 fish (5.10 ± 0.10 g) were assigned to each diet. At the end of the experiment (66 days), all groups of fish fed diets had a similar final growth and feed utilization efficiency (P > 0.05). Nitrogen retention rate was higher for the group fed the control diet and in consequence the calculated loading amount of this nutrient resulted lower when compared with the test diets. However, phosphorus retention was higher in the groups of fish fed the experimental diets (DL 26.58 ± 0.22 and DS 27.67 ± 3.05) when compared to the control diet (22.08 ± 1.12) (P < 0.05). This represents a phosphorus loading of 8.33 ± 0.23, 8.96 ± 1.02, and 11.55 ± 0.67 kg/t production for the diets DL, DS, and control, respectively. Therefore, the results indicate that lupin meal can be used as a possible plant protein source for the formulation of low-phosphorus loading diets for rainbow trout without affecting feed acceptability and growth performance. This legume represents a clear opportunity to supply the high demand for plant protein sources for aquaculture. Further studies are needed to evaluate and comapare different lupin species and varieties.

“…Excess phosphorus in fish feeds results in higher levels of excreted phosphate, which is the main cause of eutrophication in aquatic environments and consequently the deterioration of water quality [21] The reduction of phosphate excretion by fish has become imperative [22] in general, fish with the stomach, such as trout, assimilate more phosphorus than fish without the stomach, such as carp [23].…”

Summary. In order to compare the effects of three types of extruded food (A,B and C) on the growth of rainbow trout, an experimental test was conducted on June 15, 2015 at a rainbow trout farming station near river of Oumerrrabi .Morocco. The comparison of three foods of different composition and energy is performed in isoenergetic conditions. Six basins were used for this comparative test. These basins are fed with fresh water according to the open circuit with a renewal of twice an hour. The initial feeding conditions were the same for the three food types and the initial density of 1, 58 kg/m 3 (kg by volume) and an initial flow rate of 1, 04 m 3 /h. Fish are fed by ratios two to three times a day depending on the magnification stage. The sampling frequency is fortnightly, where we measure the zootechnical performance of fish and collect water samples for physicochemical analyses in order to assess the quality of the water leaving in the basins before their discharge into the river of Oum Er-Rbia. The comparative trial of three fish foods (A, B, and C) revealed that diet B is the better formulation reflected by the zootechnical performances and low phosphate release than diet A and C.

“…This negative effect could be attributed to the elevated content of readily available P of the diet which may decrease the efficacy of P retention in fish [46]. In addition, the positive correlation between dietary P and P waste of fish has been reported in previous studies [24,[47][48][49][50][51]. The practical use of dietary inorganic P to improve growth performance of catfish is therefore not recommended despite the significant improvement in the growth of the fish.…”

Effects of dietary phytase, amino acid (AA), and inorganic phosphorus (P) in canola meal diets on the growth and P waste production of Australian catfish, Tandanus tandanus were evaluated. Fishmeal protein was replaced by 30% and 45% with canola meal protein in two separate experiments, in which test diets were fortified with phytase, AA, inorganic P, or their combinations. Addition of sole phytase to the 30% replacement diets did improve growth performance and feed utilization of fish compared to those fed with the non-phytase diet. Inclusion of phytase and/ or AAs did not improve the growth and feed utilization of catfish when fishmeal protein was replaced by 45% while adding inorganic P showed significant improvement in the performance of the fish. Ortho-P waste was significantly lower while total P waste was significantly higher in fish fed with canola meal diets at both levels of fishmeal replacement. Phytase did not affect the total P waste of catfish but a combination of phytase and AA resulted in a significant reduction. Dietary inclusion of inorganic P significantly elevated the total P waste of catfish compared to that of the control fish. It was concluded that the use of canola meal in combination with inorganic P in diets for Australian catfish could significantly increase nutrient pollution in aquaculture
