“…According to Schafberg et al (2018), the fatty acid (FA) profiles of the fish fillets were determined as fatty acid methyl esters [13]. The results were expressed as g fatty acid 100 g −1 biomass.…”

“…Two important, but very controversially discussed fish feed ingredients are fish meal and fish oil. Fish meal and fish oil production is a huge industry that forces the exploitation of local seas and, in most cases, it is not sustainable at all, although a quarter of the world's fish meal is made of fish processing waste as a raw material [3,[11][12][13][14][15]. Another imported aspect is the price for fish meal and oil, which has significantly increased in the last decades [13].…”

“…For example, Øverland et al (2009) substituted fish meal with pea protein in diets for Atlantic salmon (Salmo salar) [29], whereas Barrows and Frost [30] used co-products from the nut industry, algae, and invertebrate meals in diets for rainbow trout (Oncorhynchus mykiss) [30]. The sensory aspects such as the variation of the fillet color or the skin color are typical parameters that need to be considered, as well [13,31]. However, the variations of taste, flavor, and texture of the fillets, especially, of rainbow trout (Oncorhynchus mykiss) and pike-perch (Sander lucioperca) were hardly taken into account and accordingly have not been described yet comprehensively.…”

“…In that mix, fish meal and oil content were reduced by half (compared to the control diet). For preventing nutrient deficiency, a mixture of the microorganisms Crypthecodinium cohnii, Arthrospira sp., and Rhodotorula glutinis was used [13,31]. R. glutinis was chosen as the new lipid source.…”

In the last decades, several plant-based materials were used for the substitution of fish meal and oil in aquaculture. The present study evaluated the fish quality and the sensory differences of rainbow trout (Oncorhynchus mykiss) and pike-perch (Sander lucioperca) from three different feeding groups, which were fed a commercially available industrial (standard) diet, a control diet, and a special microorganism-based feed mix. This feed mainly consisted of a mix made of Rhodotorula glutinis, Crypthecodinium cohnii, and Arthrospira sp. and had 50% less fish meal and fish oil compared to typical control diets. At the beginning, the pike-perch population was six months old, and the rainbow trout population was 15 months old. The feeding study duration was 16 weeks and every four weeks the growth performance and several morphometric parameters were recorded. Afterwards, sensory evaluation took place to identify possible trends. Sensory evaluation revealed that the rainbow trout groups did not show any significant differences to the standard and control fish fillets with regard to odor, texture, and taste. The effects on rainbow trout growth performances and carcass parameters were similar to the standard group. The feed mix was not optimal for pike-perch farming, which was also reflected by significantly adversely affected growth performance and carcass parameters. The sensorial evaluation showed an opposite trend: here, only small differences in the fillets from the feed mix and standard/control diet were observed.

A 61-day growth experiment was carried out to evaluate the potential of a poultrybased protein (PBP) comprising of feather meal (FeM) and poultry meat and bone meal (PMBM), as a fishmeal (FM) substitute in diets of juvenile pikeperch (Sander lucioperca, L.). Pikeperch (initial body weight 113.12 g) were randomly distributed in groups of 250 fish in twelve 1.8 m 3 circular recirculating aquaculture system (RAS) tanks, and fed four isonitrogenous (52% crude protein), isolipidic (17% crude lipid), and isocaloric (21.80 KJ/g energy) experimental diets. The feeds contained FM as the primary protein source (PBP0) or PBP replacing 20 (PBP20), 40 (PBP40), or 60% (PBP60) of the FM. Based on appetite and calculated uneaten feed, the feeding rate was initially set at 1.5% and subsequently reduced to 1% of the total tank biomass towards the end of the study. At the end of the experiment, the average feed intake ranged from 1.93 to 2.00 g/fish/day (p > 0.05). No adverse effects on growth and feed efficiency were observed in fish fed diets PBP0, PBP20, and PBP40. Particularly, the final body weight (FBW) (248.73, 240.11 g), feed conversion ratio (FCR) (0.86, 0.91), specific growth rate (SGR) (1.29, 1.35%/day), and protein efficiency ratio (PER) (2.20, 2.12) of fish fed PBP20 and PBP40 were not significantly different from the control PBP0 whose values ranged from 248.11 g, 0.89, 1.27%/day, and 2.18, respectively (p > 0.05). In all treatments, the condition factor (k) (1.31 to 1.33), hepatosomatic index (HSI) (2.35 to 2.70%), visceral somatic index (VSI) (6.87 to 7.19%), and whole-body composition of crude protein (57.77-58.28%) and crude lipid (23.85-26.85%) were not significantly influenced by the dietary PBP inclusion level (p > 0.05). However, whole-body ash content was significantly higher in PBP60 (14.66%) compared to the other treatments (12.57-14.43%) (p < 0.05). Based on the results from this study, up to 40% of FM can be replaced by PBP in diets for pikeperch juveniles without compromising growth performance and feed utilization.
