Monitoring Ozone (in the air) in Hatchery & Fish Farm Ozone Injection Systems
Hatcheries, fish farms and such in the aquaculture industry require clean water to maintain a high survival rate while rearing aquatic animals. Contaminated water increases the risk of infection which in turn can compromise production. A common way to disinfect water is by generating ozone on-site with an ozone generator, which is commonly inside an ozone generator room. For human safety, the ...

Carbon footprint of aquaculture in eastern India
The present study was conducted to determine the carbon (C) footprint of different aquaculture production systems in India. The total input (kg CE/ha) in different cultures, respectively, was 1,811 to 4,144 for scampi, 4,417 to 5,913 for polyculture, 4,090 to 8,873 for shrimp and 2,417 to 2,786 for carp. Of the total inputs, feed accounts for around 90% of carbon equivalent (CE), in all ...

Recirculatory Aquaculture System (RAS)
Introduction: Recirculation Aquaculture System (RAS) is a generation in which water is recycled and reused after filtration and elimination of suspended rely and metabolites. The approach is used for highdensity lifestyle of diverse species of fish utilising minimal land place and water. It is an in depth approach (better densities and greater rigorous management) than different aquaculture ...

Biofloc Systems in Aquaculture: How Harnessing Beneficial Bacteria Is Revolutionizing Aquaculture
With almost eight billion people on earth, the demand for aquatic food is increasing. Aquaculture production is projected to rise from 40 million Metric Tons by 2008 to 82 million Metric Tons in 2050. Moreover, the expansion of aquaculture is also restricted due to land costs and by its strong dependence on fishmeal and fish oil. Additionally, environmental degradation and pollution have been ...
