Reliable figures on the carbon footprints of different aquaculture species are hard to find – not least due to the variety of production systems they come from – but all suggest that aquaculture holds its own against oth…

Producing tilapia in marine environments offers a number of advantages over traditional freshwater farming of these fish – saltwater is more readily available in most countries, escaped fish are less likely to become inv…

Wild broodstock are still widely collected – both for aquaculture and for restocking purposes – but ensuring the health and welfare of these mature finfish requires careful capture and transport procedures.

Heterosis, the well-known concept of “hybrid vigour”, has been utilised to improve fitness-related traits – like growth, fecundity and disease resistance – in a number of cultured aquatic species over the years.

After decades of frustration, one of the least well-known elements of the aquaculture industry, frog farming, could be poised for growth.

Over the past few months, aquaculturists in many parts of the world have begun to focus their attention on formulating strategies to survive difficult economic conditions. As national economies trend (or plummet) downwar…

When considering ongoing genetic improvement efforts in tilapia culture, comparisons with the development of the modern chicken industry often present themselves.

Interest in tank-based shrimp production systems has been increasing in recent years in North America and Europe, while it's also slowly gaining traction in tropical regions too.

Despite severe economic challenges over the years, the US catfish farming industry is now advancing again thanks to new technologies and production strategies - including the use of split ponds.

In the first installment of a new monthly column for The Fish Site, Professor Greg Lutz looks at how Louisiana’s crawfish farmers are faring in an extraordinary year for the sector.
