Understanding biofloc in aquaculture production systems (Part 2)
Sludge at harvest time, etc. There is not a single universal set of guidelines that can be followed, i.e. a recipe, for the production of biofloc. There are, however, some consistent features of these systems and understanding what they are and ensuring that the system is conducive to the formation of these particulate materials will go a long way towards ensuring that a degree of reproducibility ...

Understanding biofloc in aquaculture production systems (Part 1)
Since 2009, protein from aquaculture production has surpassed that of fisheries for the first time in history. Aquaculture is simply a water-based agriculture with a long history. It is an essential source of nutrition, as well as a source of income for large number of communities. Aquaculture is here to stay, despite opposition to aquaculture from segments of the NGO community and commercial ...

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 ...

Bioeconomic modelling and salmon aquaculture: an overview of the literature
Bioeconomic models can be used to assist producers and decision-makers in identifying optimal production system designs, operation management strategies, and alternative development and policy approaches. This paper reviews the literature on bioeconomic modelling in aquaculture since 1993 and builds on an earlier article by Leung (1994) which examines this literature for the 1974-1993 period. In ...

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 ...

Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment
Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...
