Usability of some plant protein ingredients in the diets of Siberian sturgeon Acipenser baerii Brandt

Abstract

Abstract. This study investigated the effect of partially replacing fish meal (FM) in diets with plant protein ingredients on the growth, feed intake, feed efficiency, and nutrient retention of Siberian sturgeon, Acipenser baerii Brandt, juveniles. FM was replaced with soy protein concentrate (SP) and rape meal (RM). Three experimental feeds (40% crude protein, 10% fat) were prepared by extrusion. The protein sources in diet FM were fish meal, blood meal, and fish hydrolysate. In diet SP, the fish meal and fish hydrolysate were substituted with soy protein concentrate, and in diet SP-RM, with soy protein concentrate and rape meal. Each diet was fed to triplicate groups of sturgeon with a mean initial mass of 14 ± 1.3 g. The growth test lasted for 50 days, and were carried out in flow-through tanks of 600 dm 3 capacity. The sturgeon from group FM reached an individual body weight that was about 10% higher than that of the fish from the other dietary variants; the significance of the differences was confirmed statistically (P < 0.05). The specific growth rates (SGR) were similar during the growth test (about 4% d -1) and did not differ significantly. The feed conversion (FCR) and protein efficiency (PER) ratios were not significantly affected by the different dietary treatments, and were about 1.2 and 2.1, respectively. The proximate composition of the sturgeon bodies was similar, except with regard to lipid content. Protein retention, which ranged from 29.5 to 33.2%, was higher in groups SP and SP-RM. Lipid retention was the lowest in the SP-RM group. The results indicated that soy protein concentrate and rape meal are sufficient partial fish meal substitutes in feed for sturgeon juveniles.

Growth performance, body composition, hematological, and serum biochemical responses of beluga (Huso huso) juveniles to different dietary inclusion levels of faba bean (Vicia faba) meal

“…A similar trend was observed in the present study, but crude protein in whole fish body was not significantly reduced by the dietary treatments. Similar results have previously reported in Nile tilapia (Azaza et al 2009) and Siberian sturgeon (Acipenser baerii) (Mazurkiewicz et al 2009) fed diets containing FBM and some plant protein ingredients, respectively.…”

“…Such a process can be described by reduced deposition of fat in the fish received these treatments, which influenced the size of the liver. On the other hand, no changes were observed in body lipid contents with the addition of vegetable protein in the diet of Siberian sturgeon (A. baerii) (Mazurkiewicz et al 2009). Our results agree with the results of Gaber (2006) and Azaza et al (2009), who reported a reduction tendency in body lipid content and an increasing trend in whole-body moisture content in Nile tilapia fish fed with high levels of broad bean meal (V. faba).…”

Growth performance of Persian sturgeon fry, Acipenser persicus, fed diet containing different protein and energy levels

“…There are similar findings showing that protein requirement for optimum and maximum growth in white sturgeon larvae range from 40 to 50%, respectively (Hung 1991; Hung, 2000; Hung and Deng, 2002). However, there are other results showing that the optimum protein requirement for sub‐yearling sturgeon is somewhat lower approximating 40% (Stuart and Hung, 1989; Kaushik et al, 1989; Mohseni et al, 2007; Mazurkiewicz et al, 2009). A larger demand for protein appears to be related to fish age and/or size and supports the idea that dietary protein requirement diminishes as fish grows older (NRC, 1993; De Silva and Anderson, 1995).…”

Effects of insect diets on the gastrointestinal tract health and growth performance of Siberian sturgeon (Acipenser baerii Brandt, 1869)

“…The most available are plant meals. However, some plant meals resulted in growth depression, i.e., soybean meal (SBM) [43], soy protein concentrate, and rapeseed meal [55]. Other meals, such as sesame oil cake and corn gluten [37], caused a reduction in growth performance in cases with inclusion levels higher than 24% and was the same with wheat gluten [4].…”
