Biofloc: A sustainable dietary supplement, nutritional value and functional properties

Effects of Replacement Fishmeal with Biofloc on Feed Utilization and Growth Performance, Morphological and Chemical Characteristics of Red Tilapia

“…The chemical composition of diets and biofloc is presented in Table 1. Biofloc contain protein (34.83%), crude fiber (5.65%), fat (13.10%), ether extract (32.75%) and ash (9.08%) as indicated in other studies (Khanjani et al, 2023;Gullian-Klanian et al, 2023). The results indicated the higher the level of biofloc in the diet of fish, the lower feed efficiency and growth performance, morphological and chemical body features, and blood profiles.…”

Biofloc meal production protocol through three stages: thickening, dewatering and drying, and its effect on the proximal composition

“…The results of the study indicate that to produce 1 kg of bio oc meal 1,389 L of water with a bio oc concentration of TSS = 720 mg L -1 is necessary; however, the volume of water can vary according to the concentration of TSS that varies from 200 to 500 mg L -1 (Hargreaves 2013). Although the performance can be considered low compared to the performance of mono species cultures of microalgae, yeast, or bacteria (30-130 g L -1 ) (Gamboa-Delgado and Márquez-Reyes 2016), the production of a renewable feed such as bio oc meal can provide environmental bene ts reducing the negative impact of the aquaculture e uents on the environment ( The bio oc meal, in addition to the proteins and lipids, contains bioactive components (carotenoids, chlorophyll, phytosterols, bromophenols, amino sugars, free amino acids, and vitamins) that positively in uence the growth of organisms by improving the rate of ingestion, digestibility, absorption, assimilation, and health, thus, it can also be considered as a practical additive in aquafeeds (Ju et al 2008;Khanjani et al 2023). Bio oc technology can be an excellent source of microbial protein (El-Sayed 2020); therefore, it is important that farms with BFT establish bio oc recovery protocols to avoid environmental impact and obtain complementary protein.…”

“…Aquaculture feeds use sh meal as its main protein source, due to its nutrition digestibility, and palatability (El-Sayed 2020); however, to date, the sheries of foraging species, from which the sh meal is acquired, are at their sustainable limit, which can restrict the growth and the future of aquaculture (FAO 2020). For this reason, the investigation of alternative and functional protein ingredients that partially or totally substitute sh meal in aquaculture feed is a priority (Khanjani et al 2023).…”

Integrated multitrophic culture of shrimp Litopenaeus vannamei and tilapia Oreochromis niloticus in biofloc system: A pilot scale study

“…Due to a better maintenance of water quality, this system can reduce water use by up to 90% compared to traditional systems (Krummenauer et al, 2014), allowing culture at high stocking densities (Wasielesky et al, 2013), reducing the use of land (Liu et al, 2017) and optimizing the use of artificial food (Santhana Kumar et al, 2018). This is possible through the increase of the C: N ratio in water, with the use of organic carbon sources and constant aeration, stimulating the production of microorganisms that will both work on the metabolization of nitrogenous compounds and serve as natural food for reared animals (Krummenauer et al, 2011;Lara et al, 2017;Khanjani et al, 2023).…”
