“…The utilization of zooplankton dried biomass as a feed ingredient showed promising results to replace fish meal in aquatic diets [16]. It has been used to replace FM in the diet of sea bass up to 100% [17], crustacean (Callianassa) meal succeeded in substituting 25% of FM in the diet of Nile tilapia, Oreochromis niloticus [18], and Gammarus meal with partial or total replacement of FM in the diet of Siberian sturgeon, Acipenser baerii [19], among others.…”

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.

“…The result was similar to the observation of Hongxia, et al [45], who found that a 60% replacement level of FM by daphnia magna meal significantly increased the weight gain, specific growth rate, and protein efficiency of Pelteobagrus Fulvidraco fingerlings. Other studies have also found that replacing FM (control diet contained 35% FM) with zooplankton meal up to 100% significantly improved growth performance, PER, and FCR of seabass, Dicentrarchus labrax, fingerlings [31]. In addition, Dahpnia magna meal as an FM alternative in the diet (control diet contained 18% FM) of grey mullet larvae could replace up to 75% of FM, which recorded the best growth and feed utilization parameters [33].…”

“…Zooplankton meal succeeded in replacing 100% of FM in the diet of Dicentrarchus labrax fingerlings without compromising growth performance and feed utilization [31]. The study of Sharahi, et al [32] revealed that the replacement of FM with gammarus meal up to 20% significantly improved different growth performance criteria and feed utilization of Siberian sturgeon, Acipenser baerii.…”

Fishmeal is the most expensive feedstuff in the aquafeed and one of the most environmentally limiting factor of aquaculture development. Therefore, the search for alternative protein sources is a continuous process. The present feeding trial was conducted to evaluate the effects of replacing fishmeal with zooplankton biomass meal (ZBM) on the growth performance, nutrient utilization, intestine, and liver histological changes of grey mullet, Mugil cephalus (initial weight of 0.10 ± 0.01 g). Five isoproteic (35% crude protein) and isolipidic (8% crude lipid) diets were formulated as the control diet (Z0) and the other four diets (Z25, Z50, Z75, and Z100), where 25%, 50%, 75%, and 100% of fishmeal was replaced by ZBM, respectively. After 60 days of feeding, the final weight, weight gain, and daily growth index of the grey mullet fed the Z100 diet were higher than those fed the control diet (p < 0.05). In addition, the better values of feed conversion ratio, protein efficiency ratio and lipid efficiency ratio were recorded in the fish fed with the Z100 diet. Additionally, the intestinal villus length, crypts depth, and muscle thickness were significantly improved with ZBM inclusion (p < 0.05). Meanwhile, there were no histopathological changes observed on the liver when compared with the control group. From the economic point of view, dietary substitution of fishmeal by ZBM (Z100) reduced the cost of diet formulation by 18% and the price per kg weight gain by about 40%. Overall, according to the findings of this study, substituting fishmeal with ZBM up to 100% could improve growth performance, feed utilization, gut health status, and profit ability of rearing M. cephalus juveniles.

“…Concerning the nutritionalrichness in proteins, lipids, carbohydrates, fatty acids, and amino acids, there is no doubt that zooplankton are efcient, feasible, and economical live foods for cultured aquatic animals. More studies are encouraged to evaluate the efects of replacing fsh meal with zooplankton on the growth performance, protein efciency ratio, and feed conversion ratio of cultured aquatic animals such as European sea bass Dicentrarchus labrax [136]. 3.4.…”

The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets. They contain essential proteins, lipids, carbohydrates, amino acids, and fatty acids and are considered promising supplementary nutrition sources for cultured aquatic animals. Particularly, they are available to aquatic animals throughout the day, and an adequate supply of them as starter foods during the larvae stage ensures high survival. Since formulated feeds constitute more than 50% of aquaculture production costs, optimizing the utilization of natural biota and reducing dietary nutrient input without compromising animals’ growth should be a priority to improve the economic success and sustainability of aquaculture. From this scenario, the present review offers an updated view of the natural biota category in aquaculture systems, their nutritional components, and their contributions to the growth of cultured aquatic animals. Taken together, this review emphasizes the significant roles of natural biota playing in the growth of aquatic animals and encourages maximizing utilization of natural biota to improve feed conversion efficiency and aquaculture sustainability.
