“…Isolation, cultivation, nutritional compositions, and preparation of Daphnia meal, D. magna, (DMM) were conducted as described previously by El-feky and Abo-taleb [7]. At the end of the culture of D. magna as described previously [7], D. magna were harvested, dried, powdered, and preserved at −20 • C until further analysis or utilization as DM. Dry matter content (DM%), crude protein (CP%), ether extract (EE%), crude fiber (CF%), nitrogen-free extract (NFE%), and gross energy (GE Kcal kg −1 ) of DMM are presented in Table 1.…”

“…Dry matter content (DM%), crude protein (CP%), ether extract (EE%), crude fiber (CF%), nitrogen-free extract (NFE%), and gross energy (GE Kcal kg −1 ) of DMM are presented in Table 1. As described previously by El-Feky and Abo-Taleb [7], DMM resulted with strong nutritional values of dry matter content (92%), crude protein (47.7%), ether extract (10.2%), crude fiber (2.1%), ash (17.8%), nitrogen-free extract (22.2%), caloric value (3337 K cal kg −1 ), β-carotene (6510 IU/100 g), folic acid (110 µg 100 g −1 ), and tannic acid (56 mg 100 g −1 ). Values of vitamins B 2 , B 6 , B 6 , B 12 , A, E, and D were 203 mg 100 g −1 , 176 mg 100 g −1 , 191 mg 100 g −1 , 318 IU 100 g −1 , 17 mg 100 g −1 , and 19.2 mg 100 g −1 , respectively.…”

“…With the increase in the number of fish farms, the need for zooplankton has increased and the trend of cultivating zooplankton, as live food, has increased significantly in the last decades [4]. Several zooplankton species were successfully cultured and utilized in aquaculture, include rotifer, Brachionus plicatilis [5], Artemia franciscana [6], amphipod, Gammarus pulex [3], copepods, Oithona nana [4], and Daphnia magna [7]. For many nutritional aspects [8,9], algal cells are the basic and the recommended food item for zooplankton [5,6], while, several food items have been utilized in feeding for different zooplankton species, include agriculture, industrial waste products, and animal manures [10][11][12].…”

“…Among zooplankton species, D. magna has excellent nutritional content that is recommended for use in feeding of fish larvae [7]. Cultivation of this species is not difficult as it can feed wide varieties of unused food residues.…”

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.

Various studies have shown the importance of using different types of Zooplankton biomasses as an additional substance in the diet of fish. In addition, the drainage water of the fish cultures could be used in plant irrigation. In this study, biomasses of water flea Daphnia magna and Gammarus pulex collected and tested, for the first time, their effect against pathogenic microorganisms and on plant germination. The results showed significant antibacterial activity of D. magna and G. pulex against Staphylococcus aureus and Pseudomonas aeruginosa bacteria, as well as antifungal activity against Alternaria solani and Penicillium expansum, which gives the possibility to be used as biocontrol against these bacteria and plant pathogenic fungi. Furthermore, both animals showed positive activity in the germination rate of Vicia faba seed, reaching 83.0 ± 3.5 and 86.0 ± 3.8%, respectively. In conclusion, the biomasses of D. magna and G. pulex are promising and effective agents for their use in the medical field against some pathogenic microbes and as stimulators of plant growth.
