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 ...

Nitrate accumulation in biofloc aquaculture systems

Aquaculture, 2020
Abstract Minimizing ammonium is one of the most important concerns in the practice of aquaculture. Chemoautotrophic bacterial nitrification (CBN) and heterotrophic bacterial assimilation (HBA) are the two main ammonium pathways in aquaculture water under light-limited conditions. CBN oxidizes ammonia–nitrogen (NH4+-N) to nitrite–nitrogen (NO2−-N) 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.
