MARINE PROTECTED

AREAS AND

AQUACULTURE

Aquaculture is one of the fastest growing marine
activities, so an integrated approach is needed to
define sustainable aquaculture and how it could
work effectively with MPAs.

Fish farming and specifically salmon farming
is currently problematic. Whether in Scotland,
Norway or Chile, it seems to have affected wild
salmon stocks by encouraging the proliferation
of sea lice, genetic contamination and the in-
troduction of antibiotics. In Chile in particular, it
has destroyed precious fjords to the point where
aquaculture is no longer possible.

There has been a certain consensus regarding
the potential to further integrate algae cultivation
and invertebrate farming within MPAs, in relation
to marine fish farming, although they require a
much larger marine area to produce the same
level of food. Marine protected areas managed
locally in tropical coastal regions have demons-
trated positive examples of synergies between
invertebrate aquaculture and MPAs in a local
co-management context. Non-fed species such
as sea cucumbers, algae and sponges, cultivated
in protected waters, provide alternative methods
of subsistence, thus advancing conservation ob-
jectives. A responsible business approach and
investment is needed to develop these models
on a larger scale.

Before cultivating oceans intensively, it would be
irresponsible not to learn from unsustainable land
The MBI would like to wholeheartedly thank farming. Circular economy models such as Inte-
H.R.H. Princess Anne, chancellor of the University grated Multi-Trophic Aquaculture (IMTA), where
the “waste” from one cultivated species is used
of Edinburgh, and the entire University team: to feed another, are some of the most effective
Prof. Peter Mathieson, Prof. Sandy Tudhope, Dr. Meriwether and sustainable feeding systems and amongst
Wilson, Ms. Sanne Diskstra-Downie, Ms. Cassie Mesouani, the most promising for MPA development.
Ms. Adele Willoughby, and Mr. Corin Campbell.

the Monaco on 24 and 25 March 2019.
