“…The amino acid profile of all experimental diets was well balanced, which was similar to the profile reported by Aas et al (2006) who included up to 36% bacterial protein meal in Salmo salar. They reported good final fish growth at the end of experimental period, attributing these results to well balanced amino acids in the experimental diets.…”

Nogales Mérida S., Jover Cerdá M., Martínez Llorens S., Tomás Vidal A. 2011. A study of partial replacement of fish meal with sunflower meal on growth, amino acid retention, and body composition of sharpsnout seabream, Diplodus puntazzo (Actinopterygii: Perciformes: Sparidae). Acta Ichthyol. Piscat. 41 (1): 47-54.Background. Our previous study demonstrated that sharpsnout seabream, Diplodus puntazzo (Walbaum, 1792), can be fed with up to 34.8% sunflower meal (SFM), with excellent results in growth parameters and feed efficiency. The aim of the current study was to test the replacement of fish meal with SFM in the diet formulation for sharpsnout seabream and to evaluate growth, nutritive parameters, amino acid retention, and body composition of the fish during the fattening period. Materials and methods. Sixteen baskets (300-L capacity), each with thirteen fish, were distributed in a recirculated saltwater system to allow four experimental diets containing 40% crude protein (CP) and 20% crude lipid (CL) with 0%, 11.7%, 23.5%, and 34.8% SFM partially replacing fish meal to be used in quadruplicate for this experiment. The fish were fed these diets ad libitum during the experiment, which lasted for 162 days. Growth, nutrition efficiency, biometrics, carcass composition, amino acid composition, and amino acid retention of the experimental fish were evaluated.Results. There were no statistical differences in the growth parameters among the treatments. However, fish fed a diet containing 34.8% SFM had the lowest feed intake (FI), lowest feed conversion ratio (FCR), and the highest protein efficiency ratio (PER). There were also no statistical differences in the biometric parameters although fish fed the diet containing 10% SFM had the lowest CP levels. Leucine was the only difference in the essential amino acid (EEA) profile with fish fed a diet containing 11.7% SFM having the lowest levels of leucine. Although there were fluctuations among the amino acid retentions, they were not statistically significant. Conclusion. SFM (up to 34.8%) can be included in the diets of sharpsnout seabream, thereby, replacing 27% of the fish meal without altering the fish growth.

“…The EAA retention found in our study was low in comparison with rates reported by Helland et al (2006) and Aas et al (2006). This difference may be due to the high FI in relation to low final fish growth achieved at the end of the experiment.…”

“…Duckweed has a better essential amino acid profile than most vegetable protein sources (Chaturvedy et al, 2003). Moreover, the amino acid composition is similar to that of fish meal, although, it is deficient in lysine (Aas et al, 2006).…”

“…In addition to their role in fermentation, bacteria are an important source of high quality protein with up to 70% (Aas et al, 2006). The growth of bacteria during the fermentation process was better with 10% molasses and the pH decreased significantly from 24 to 144 h with all percentages of molasses.…”

Lemna sp. flour was fermented with bacteria as a source of protein for the preparation of white leg shrimp diets. Pediococcus pentosaceus was isolated from Litopenaeus vannamei and Litopenaeus stylirostris juveniles and characterized with biochemical (Gram stain, hemolytic activity, extracellular enzymatic activity, hydrophobicity, bacterial growth kinetics, salt tolerance, and cell count) and molecular (16S ribosomal gene) tests. The presumptive bacillus (Ba4), previously isolated and characterized, was identified as Bacillus pumilus. P. pentosaceus and B. pumilus were used in the fermentation of duckweed flour, with different percentages of molasses and humidity. Both bacteria showed high growth in fermented flour. In addition, the fermented flour showed high protein content and a significant decrease in crude fiber, lipids, ashes, and phytic acid. The concentration of tannins remained unchanged. Fermentation of Lemna sp. flour improves its nutritional value and suitability as an alternative protein source in formulated diets for white shrimp L. vannamei.

“…A bacterial protein meal produced based on methane from natural gas is a new resource, and feeding experiments with rainbow trout Oncorhynchus mykiss using a feed containing up to 27% bacterial protein meal has produced positive results (Aas et al 2006). The meal has also been found satisfactory for carnivorous warm-blooded animals (Skrede & Ahlstrøm 2002).…”

There is a growing concern about the ability to produce enough nutritious food to feed the global human population in this century. Environmental conflicts and a limited freshwater supply constrain further developments in agriculture; global fisheries have levelled off, and aquaculture may have to play a more prominent role in supplying human food. Freshwater is important, but it is also a major challenge to cultivate the oceans in an environmentally, economically and energyfriendly way. To support this, a long-term vision must be to derive new sources of feed, primarily taken from outside the human food chain, and to move carnivore production to a lower trophic level. The main aim of this paper is to speculate on how feed supplies can be produced for an expanding aquaculture industry by and beyond 2050 and to establish a roadmap of the actions needed to achieve this. Resources from agriculture, fish meal and fish oil are the major components of pellet fish feeds. All cultured animals take advantage of a certain fraction of fish meal in the feed, and marine carnivores depend on a supply of marine lipids containing highly unsaturated fatty acids (HUFA, with ≥3 double bonds and ≥20 carbon chain length) in the feed. The availability of HUFA is likely the main constraint for developing carnivore aquaculture in the next decades. The availability of fish meal and oil will decrease, and the competition for plant products will increase. New harvested resources are herbivore zooplankton, such as Antarctic krill and red feed, and new produced resources are macroalgae, transgenic higher HUFA-producing plants and bacterial biomass. These products are to a limited extent components of the human food chain, and all these resources will help to move cultured carnivores to lower trophic levels and can thereby increase the production capacity and the sustainability of the production. Mariculture can only become as successful as agriculture in the coming century if carnivores can be produced at around Trophic Level 2, based mainly on plant resources. There is little potential for increasing the traditional fish meal food chain in aquaculture.
