Comparing a chemoautotrophic-based biofloc system and three heterotrophic-based systems receiving different carbohydrate sources

Growth, water quality and oxidative stress of Nile tilapiaOreochromis niloticus(L.) in biofloc technology system at different pH

“…Similarly, Luo et al () demonstrate low concentrations of phosphate on BFT compared to RAS, indicating PO 4 − ‐P cycling by microorganisms is present in bioflocs. Ray and Lotz () also found low concentration of PO 4 − ‐P, which they attributed to absorption by heterotrophic bacteria, as demonstrate for Longnecker, Lomas, and Van Mooy () and Liu, Luo et al (). The monitoring of NO 3 − ‐N and PO 4 − ‐P water levels in aquaculture systems is fundamental, because could be indicators for reuse as well as for correct discharge as effluent.…”

Effects of different carbon sources and dietary protein levels in a biofloc system on growth performance, immune response against white spot syndrome virus infection and cathepsin L gene expression ofLitopenaeus vannamei

“…bacteria, filamentous cyanobacteria, protozoa, nematodes, phytoplankton and fungi) kept in suspension by strong agitation of water in a pond or tank (Avnimelech et al, ). The use of biofloc technology (BFT) in the culture of aquatic organisms, especially shrimp, has gained great attention, because it offers a practical solution to control water quality and it improves biosecurity under limited water exchange (Ekasari et al, ; Ray & Lotz, ; Xu & Pan, ). In fact, biofloc can improve shrimp overall performance through immunomodulation (e.g.…”

“…In fact, biofloc can improve shrimp overall performance through immunomodulation (e.g. blocking quorum sensing of pathogenic bacteria), water bioremediation as well as it provides extra nutritional supplements and exogenous digestive enzymes (Ekasari et al, ; Emerenciano, Cuzon, Paredes, & Gaxiola, ; Ray & Lotz, ). Furthermore, a biofloc powder is suggested as a sustainable and cost‐effective alternative source for fishmeal in the shrimp feed (Lee, Kim, Lim, & Lee, ; Yun, Shahkar, Katya, Kim, & Bai, ), and also it could act as a source of probiotic bacteria for the culture of shrimp (Ferreira et al, ; Chiu, Guu, Liu, Pan & Cheng, ).…”

Carbon supplementation and microbial management to stimulate artemia biomass production in hypersaline culture conditions

“…Various carbon sources including glucose, sucrose, glycerol, molasses, starch, rice bran, etc. have been successfully applied to stimulate biofloc development in fish and crustacean culture systems, such as for hybrid tilapia fingerlings Oreochromis niloticus × Oreochromis aureus (Crab, Kochba, Verstraete & Avnimelech ), Marsupenaeus japonicus (Crab, Chielens, Wille, Bossier & Verstraete ; Zhao, Huang, Wang, Song, Yan, Zhang & Wang ), Litopenaeus vannamei (Xu & Pan ; Correia, Wilkenfeld, Morris, Wei, Prangnell & Samocha ; Ray & Lotz ), Farfantepenaeus sp. (Emerenciano, Ballester, Cavalli & Wasielesky ; Emerenciano, Cuzon, Paredes & Gaxiola ) and African catfish Clarias gariepinus (Bakar, Nasir, Lananan, Hamid, Lam & Jusoh ).…”
