Effects of carbohydrate addition strategy and biofloc levels on the establishment of nitrification in biofloc technology aquaculture systems

Aquaculture, 2020
Abstract The current study evaluated the effect of a carbohydrate addition strategy set at two biofloc levels on the establishment of nitrification in new biofloc technology aquaculture systems. Three carbohydrate addition strategies were chosen as follows: one-time glucose addition with 20:1 of the input C/N ratio, glucose additions at a C/N ratio ...

Improvement of biofloc quality and growth of Macrobrachium rosenbergii in biofloc systems by Chlorella addition

Aquaculture International, 2021
This research aimed to elucidate the effect of Chlorella sp. addition on biofloc quality and growth of Macrobrachium rosenbergii juveniles in biofloc systems. Four treatments of freshwater prawn nursery culture systems were tested, i.e., control system with clear water system at a regular water exchange at about 50% every 2 weeks; control system with ...

Effects of biochar on microbial community in bioflocs and gut of Oreochromis niloticus reared in a biofloc system

Aquaculture International, 2021
This study investigated the effects of biochar application on the bacterial community structure in bioflocs and intestines of Oreochromis niloticus cultured in a biofloc system and further evaluated its effects on some intestinal enzyme activities. Three carbon treatments, the control G, sole application of glucose; B, sole application of biochar; and ...

A Qualitative and Biochemical Analysis of Biofloc from an Indoor Biofloc Technology System Culturing Oreochromis Karongae.

University of Zambia Journal of Agricultural and Biomedical Sciences, 2023
The structure of microbial communities in a biofloc Technology (BFT) system has a great influence on the optimal functioning of the system. This makes understanding the microbial composition in BFT of paramount importance. A study was conducted to characterise the microorganisms in an indoor biofloc technology system.

Kinetics of UV inactivation of wastewater bioflocs

Water Research, 2012
Ultraviolet disinfection is a physical method of disinfecting secondary treated wastewaters. Bioflocs formed during secondary treatment harbor and protect microbes from exposure to ultraviolet (UV) light, and significantly decrease the efficiency of disinfection at high UV doses causing the tailing phenomena. However, the exact mechanism of tailing and

Goldfish (Carassius auratus) larviculture in biofloc systems: Level of Artemia nauplii, stocking density and concentration of the bioflocs

Aquaculture, 2021
Abstract The present study evaluated the use of a biofloc system (BFT) for the larviculture of goldfish (Carassius auratus). Two experiments were carried out, of which the first evaluated two culture systems (BFT and clear water) and three densities of Artemia nauplii (100, 200 and 300 nauplii larvae−1).
