The formulator of aquatic diets is part of a continuous search for alternative protein sources instead of depreciated fish meal. The utilization of zooplankton as a feed ingredient is an interesting trend due to their high-quality protein content and abundance of essential nutrients. The current study aims to investigate the effects of partial and total replacement of fish meal (FM) by Dahpnia magna meal (DMM) on growth performance, feed utilization, histological, and economic status of mullet, M. cephalus, larvae. In addition to the control diet, 100% FM, D0, four diets containing DMM at different levels were used: 25% (D25), 50% (D50), 75% (D75), and 100% (D100) replacement of fish meal. A total of 300 larvae (0.097 ± 0.001 g) were equally divided into five groups (three replicate per each group) at a density of 200 larvae m−3. The aquariums were renewed at a rate of 30% daily. During the 60-day experimental period, all larvae were fed their respective diets at a level of 20% of live body weight, five times a day (9.00 a.m., 12.00, 15.00, 18.00, and 21.00 p.m.). The results indicated that compared to D0, fish fed D75 recorded the highest significant value of growth, and feed utilization parameters, while fish fed D100 achieved the lowest feed cost and incidence cost, and the highest profit index and economic efficiency ratio. A strong correlation was reported among weight gain, feed conversion ratio and fish meal replacement with DMM; R2 = 0.94 and 0.91, respectively. The fit regression model representing mullet response to FM replacement with DMM is a poly-nominal regression model with maximum response at 75–100%. The histological investigation of the intestine revealed an improvement of histomorphometric indices and goblet cell number with increasing DMM inclusion levels. These findings confirmed that 75% to 100% partial substitution of FM with DMM is the ideal replacement for mullet, M. cephalus, larvae for improving fish growth performance and feed utilization.

“…One of the main challenges in achieving productive, feasible, sustainable aquaculture is to develop alternative prophylactics that could help to maintain high animal welfare standards that foster better production and higher profits. Fish diets should not only provide the essential nutrients that are required for normal physiological functioning, but also serve as the medium by which fish receive other components that affect their health (Goda et al., ; Li & Gatlin, ). Baker's yeast, or Saccharomyces cerevisiae yeast, is a particularly important natural bioproduct as it contains immune‐stimulating compounds such as nucleotides, β‐glucan, mannan oligosaccharides and chitin, and it has been proved to influence the fish immune response and to promote growth (Abdel‐Tawwab, ).…”

Nile tilapia, Oreochromis niloticus (average initial weight, 5.91 ± 0.04 g), were fed four isonitrogenous and isolipidic diets for 84 days. The diets contained four levels of yeast extract (CW‐I) rich in nucleotides and β‐glucan: 0 (control), 5, 10 and 15 g/kg diet. Weight gain increased linearly, whereas the feed conversion ratio decreased linearly with increasing levels of yeast extract. The diet containing 15 g/kg yeast extract resulted in significantly better (p < 0.05) specific growth rates and protein efficiency ratios. No significant (p > 0.05) differences were found in dry matter, protein, lipid or ash contents or in haematocrit, haemoglobin or total protein contents among the treatment groups. Blood sample profiles showed an increase in white and red blood cells in fish fed 15 g/kg yeast extract in comparison with the other treatment groups. The fish fed the diets with 10 and 15 g/kg yeast extract had significantly higher albumin and globulin levels than the control group, whereas decreased levels of cholesterol and triglycerides, aspartate aminotransferase and alanine aminotransferase were noted in fish fed the diet with 15 g/kg yeast extract. Histological analysis of the liver and intestine in fish fed the control diet showed a slightly abnormal structure in these organs. Only in fish fed diets supplemented with the highest amount of yeast extract was the structure of the hepatocytes and villi almost unchanged, which indicated that the yeast nucleotides could improve hepatic function and promote liver and gut restoration.

“…are important because of their ability to produce antibiotics/metabolites which have antagonistic effects against pathogenic microorganisms ( Sun et al, 2010 ; Abarike et al, 2018 ; Kuebutornye et al, 2019 ). Literatures have proven that aquaculture animals with diet supplemented with Bacillus species as probiotics resulted in a better protein efficiency ratio, lower feed conversion ratio, and fast growth ( De et al, 2018 ; Goda et al, 2018 ; Sadat Hoseini Madani et al, 2018 ). Nimrat et al (2012) also reported that forms of Bacillus probiotics and modes of probiotic administration Bacillus probiotics did not affect the growth and survival of shrimp.…”
