“…The reduction of growth performance of Malaysian mahseer with increasing dietary lipid was in agreement with the latter group of farmed freshwater species. As shown in earlier studies (Satpathy et al 2003;Hamre et al 2004;Alam et al 2009a), this study also revealed that FCR decreased with increasing dietary lipid. It is well established that fish adjust their feed intake to meet their digestible energy requirements .…”

After protein, the second major essential macronutrient in fish diet is lipid. This study was conducted to determine the optimum level of dietary lipid for the best growth performance of juvenile Malaysian mahseer Tor tambroides. Four isonitrogenous diets containing 40% crude protein were formulated to contain different levels of lipid (5, 10, 15, or 20% on an as‐fed basis). Cod liver oil was incorporated into the feed as the main dietary lipid source used to formulate the diets while residual oil coming from other ingredients contributed about 5% of dietary lipid. The experimental diets were labeled as L5, L10, L15, or L20 to denote the levels of dietary lipid. Fish were fed the experimental diets in triplicate groups for 63 d. Growth performance, survival rate, and daily feed intake by Malaysian mahseer significantly decreased when fed diets in which levels of dietary lipid increased from 5% to 20%. However, the growth performance did not vary significantly between fish fed the L5 and L10 diets. The increase in dietary lipid significantly increased the hepatosomatic index but did not influence the viscerosomatic index. Increasing dietary lipid levels also decreased the lipid content in the whole body composition of fish. The monounsaturated fatty acid (MUFA) and n‐3 polyunsaturated fatty acid (PUFA) contents of fish liver significantly increased with the increase of dietary lipid. The results of this study suggested that 5% dietary lipid is sufficient for the best survival rate and growth performance of juvenile Malaysian mahseer.

“…The protein sparing effect of lipid has been reported in many fish species (Schulz et al., 2007; for pike perch, Sander lucioperca ; Alam et al., 2009; for black sea bass, Centropristis striata ; Biswas et al., 2009; for Pacific blue fin tuna, T. orientalis ; and Liu et al., 2011; for Asian catfish, Pangasius hypophthalmus ). Generally, protein sparing effect is observed by concomitant decrease in dietary protein and increase in dietary lipid and is more pronounced at the sub‐optimum level of dietary protein and higher level of lipid (Tibbetts et al., 2005; Mohanta et al., 2007; Schulz et al., 2007), which is not the case in the present study as the best growth and nutrient utilization of blue gourami were recorded in the medium dietary protein (350 g/kg) and lipid (80 g/kg) diet and not in the low‐protein and high‐lipid diet.…”

“…The trend of increasing weight gain, SGR, PER, PRE and ERE and decreasing FCR with increase in dietary lipid (individual effect) up to certain level and then no improvement in these parameters with further rise in dietary lipid level as observed in the present study is in agreement with the earlier studies in Tilapia aurea (Stickney and McGeachin, 1983), Heteropneustes fossilis (Anwar and Jafri, 1995), Cirrhinus mrigala (Jafri et al., 1995), Oreochromis niloticus × O. aureus (Chou and Shiau, 1996), Rhamdia quelen (Salhi et al., 2004) and M. amblycephala (Li et al., 2010). It is reported that within certain limits, increasing the dietary lipid improves feed efficiency and diet utilization in fish (Peres and Oliva‐Teles, 1999; McGoogan and Gatlin, 1999; Alam et al., 2009). But excess lipid not only suppresses de novo fatty acid synthesis but also reduces the ability of fish to digest and assimilate it, leading to reduced growth rate (Sargent et al., 1989).…”

“…Dietary protein (Pr) is the most costly macro‐nutrient per unit weight of fish feed and determines the feed cost (Cho et al., 2005; Alam et al., 2009; Liu et al., 2011). Therefore, protein requirement is always studied in aquaculture species with the aim of determining the minimum amount required to provide essential amino acids that are responsible for maximum growth (Chi et al., 2010).…”

Nine semi-purified diets were prepared with three levels each of protein (300, 350 and 400 g/kg) and lipid (60, 80 and 100 g/kg) and fed ad libitum to Trichogaster trichopterus fingerlings (0.61 ± 0.03 g) in triplicate groups (10 fish/replicate) for 90 days to determine optimum dietary protein and lipid levels. Twenty-seven flow-through fibre-reinforced plastic tanks (200 l capacity each with 100 l of water) were used for rearing the fish. The dietary protein, lipid and their interactions had significant effects (p < 0.05) on weight gain, feed conversion ratio, specific growth rate, nutrient retention and digestibility, but not on hepato- and viscerosomatic indexes (p > 0.05). Dietary protein and the interaction of protein with lipid had significant effect (p < 0.05) on whole-body dry matter, lipid and energy contents, but not on protein and ash contents (p > 0.05). But, the dietary lipid had significant (p < 0.05) effect on whole-body dry matter, protein, lipid and energy contents except the ash contents (p > 0.05). For each level of dietary protein, the increase in dietary lipid resulted significant increase (p < 0.05) in whole-body lipid contents without affecting the protein and ash contents (p > 0.05). Based on better growth and dietary performances, the optimum dietary protein and lipid levels of blue gourami fingerling are 350 and 80 g/kg diet respectively.

The human population is growing and, globally, we must meet the challenge of increased protein needs required to feed this population. Single cell proteins (SCP), when coupled to aquaculture production, offer a means to ensure future protein needs can be met without direct competition with food for people. To demonstrate a given type of SCP has potential as a protein source for use in aquaculture feed, a number of steps need to be validated including demonstrating that the SCP is accepted by the species in question, leads to equivalent survival and growth, does not result in illness or other maladies, is palatable to the consumer, is cost effective to produce and can easily be incorporated into diets using existing technology. Here we examine white shrimp (Litopenaeus vannamei) growth and consumer taste preference, smallmouth grunt (Haemulon chrysargyreum) growth, survival, health and gut microbiota, and Atlantic salmon (Salmo salar) digestibility when fed diets that substitute the bacterium Methylobacterium extorquens at a level of 30% (grunts), 100% (shrimp), or 55% (salmon) of the fishmeal in a compound feed. In each of these tests, animals performed equivalently when fed diets containing M. extorquens as when fed a standard aquaculture diet. This transdisciplinary approach is a first validation of this bacterium as a potential SCP protein substitute in aquafeeds. Given the ease to produce this SCP through an aerobic fermentation process, the broad applicability for use in aquaculture indicates the promise of M. extorquens in leading toward greater food security in the future.
