“…Furthermore, the HSI value of longfin yellowtail was not altered by feeding with S. limacinum (Kissinger et al, 2016). In the present study, the VSI (8.1-8.3) and HSI (1.3) of the algal groups were not significantly different from the values of the control group.…”

“…The authors concluded that the maximum incorporation level should be 12.5% to avoid negative effects on growth, body lipid and energy content of the fish. The growth and feed performance of longfin yellowtail (Seriola rivoliana) was affected upon feeding with the microalga Schizochytrium limacinum (Kissinger et al, 2016). Feeding European sea bass (Dicentrarchus labrax) with freeze-dried Isochrysis sp.…”

Defatted Biomass of the Microalga, Desmodesmus sp., Can Replace Fishmeal in the Feeds for Atlantic salmon

Microalgal biomass is a potential feed ingredient that can replace fishmeal and ensure sustainability standards in aquaculture. To understand the efficacy of the defatted biomass from the marine microalga, Desmodesmus sp. a 70-day feeding study was performed with Atlantic salmon (Salmo salar) smolts. Three groups of fish (av. wt. 167 g) were offered either a control feed (without the microalga) or the microalga-containing (10/20%) feeds. At the end of the feeding period, the growth indices (condition factor, specific growth rate) and survival of the microalga-fed fish were not significantly different from the respective values of the control fish, but the feed conversion ratios were inferior. The proximate composition of the whole body of salmon from the three groups did not vary significantly. Compared to the control fish, the 10% alga-fed fish had lower lipid content in their filet. The protein and lipid digestibility in the three feeds did not differ significantly, but the digestibility of energy in the 10% alga-feed was significantly lower than that of the control feed. Furthermore, comparison of the distal intestinal proteome of Atlantic salmon revealed that the expressions of Alpha-2-HS-glycoprotein-like (Ahsg), Myosin-11 isoform X1 (My11) and Dihydrolipoyl dehydrogenase, mitochondrial-like (Dld) were altered by the microalgal feeding. Examination of the physiological status of the fish based on the serum antioxidant capacities did not reveal any alga-feed-related differences. Moreover, the expression of the selected immune and inflammatory marker genes and the micromorphological observations did not indicate any aberration in the intestinal health of the microalga-fed fish. It is possible to include 20% of defatted Desmodesmus sp. in the feeds of Atlantic salmon.

“…Several enter-prises have focused on the development of high-density microalgal cultures for the production of biofuels, pigments and highly unsaturated fatty acids. Frequently, the remaining defatted material obtained from the latter processes have been proposed and tested as an ingredient for aquaculture diets Kissinger et al, 2016). However, the application of microalgal biomass as dietary ingredients in aquaculture feeds has not been significant yet since there are still technical obstacles to be overcome.…”

ABSTRACT. Different sources of microbial biomass have drawn attention as novel ingredients for aquaculture feeds. In the present study, isotopic measurements were applied to determine the contribution of dietary nitrogen supplied by two sources of microalgal biomass and fish meal, to the growth of shrimp Penaeus vannamei. Microalgae Schizochytrium sp. and Grammatophora sp. were isolated from the Sea of Cortez and massively cultured to obtain sufficient biomass. Experimental diets were formulated with low levels of microalgal biomass replacing 5 and 10% of fish meal nitrogen. Nitrogen stable isotope values were determined in ingredients, diets, and shrimp to estimate the relative contributions of the dietary nitrogen and dry matter supplied by these ingredients to the somatic growth. At the end of a feeding trial, significant differences were observed in mean final weight gain. Dietary nitrogen contributions from microalgae were similar to established dietary proportions, but when estimated on a dry matter basis, nutritional contributions were different for a diet containing 10% of Schizochytrium, which contributed 24% of dry matter to growth. Results demonstrate that low dietary inclusion levels of microalgal biomass elicit similar or higher growth rates than diets based on a fish meal only. Isotopic data indicated that microalgae actually contributed protein to tissue accretion.

“…However, because of the recent increasing cost of fishmeal, researchers have started evaluating the economic feasibility and optimum usage of these novel proteins as fishmeal substitutes. Partial fishmeal replacement with algae is also possible (Kiron et al, 2012;Al-Asgah et al, 2016;Abdel-Warith et al, 2016;Radhakrishnan et al, 2016;Kiron et al, 2016;Kissinger et al, 2016), especially in tropical areas where they are found in plentiful amounts. Kiron et al (2016) observed that partial substitution of fishmeal with defatted biomassof Desmodesmus sp.…”

Aquaculture expanded around 8.6% per year during the period 1980-2012. It is the greatest growing food producing sector. The intensification of fish production from aquaculture has made its demand for fishmeal from small pelagic fishes as an increasingly important issue. Recognizing the vulnerability of small pelagic fishes to challenges of climate changes is serious. It will have consequent challenges in terms of ensuring economically, socially and environmentally responsible fishmeal production practices. The possibility of replacing fishmeal with nutritionally comparable feedstuffs would diminish stress on prices of feed inputs resulting from captured fisheries. Diverse types of alternative (plant, animal, fishery by-products and novel foods) protein sources have been experienced in a variety of aquaculture feeds. This review aims to appraise the different kinds of fishmeal alternatives and the most proper substituent in fish diets. The paper in hand proposed that some of the described fishmeal alternatives could leads to a considerable drop in small pelagic fishes utilization, but still they might be more cost-effective than fishmeal. Studies should take into account both economic and biological assessment of dietary protein sources as fishmeal substituents. On the other hand, the environmental impacts of such alternatives should be evaluated in order to guarantee sustainability of fish feed industry.
