One of the major criticisms leveled at aquaculture is the sustainability of feeds in particular, the levels of fishmeal and fish oil.
However, aquaculture's reliance on fishmeal and fish oil may be about to change thanks to a 100 percent vegetarian diet for marine fish developed at the University of Maryland Center for Environmental Science's Institute for Marine and Environmental Technology, USA.
The findings led by Aaron Watson and Allen Place are published in the August
issue of the journal Lipids.
"Aquaculture isn't sustainable because it takes more fish to feed
fish than are being produced," said Dr Watson.
"But a new
vegetarian diet might change everything."
Supported by another paper published in the Journal of Fisheries and Aquaculture,
the team has proven that a completely plant-based food combination can
support fast-growing marine carnivores like cobia and gilthead sea bream
in reaching maturity just as well as - and sometimes better
than - conventional diets of fishmeal and fish oil made from wild-caught
fish.

Mola fish have been introduced to a beel (swamp) in Bangladesh in a bid to meet growing protein demand.
The native species was been added to a swamp in Bhelakuba
Beel at Kisamatfolia under Gidari union of Sadar upazila as part of a WorldFish project.
The plan is to encourage mola farming in other swamps to enhance production.
Under the project, 92 kg of mola fish fry was released into the swamp in September in 2012.
Seafish, the UK's seafood support body, has appointed two new members fo staff.
Tom Pickerell will join the team as technical director working out of the Grimsby office.
In Edinburgh, Rob
Bruce will take on the role of corporate relations director.
