THE STATE OF WORLD FISHERIES AND AQUACULTURE

factors, including among others: population
increasing at a higher rate than food fish supply;
stagnation of fish production because of pressure
on capture fisheries resources; and a poorly
developed aquaculture sector. Moreover, low
income levels contribute to low fish consumption,
as do inadequate landing, storage and processing
infrastructure and the lack of marketing and
distribution channels necessary to commercialize
fish products. However, it should be stressed
that in Africa actual values are probably higher
than indicated by official statistics, in view of
the under-recorded
contribution of subsistence
fisheries, some small-scale fisheries and informal
cross-border trade.
The broad trends that have driven growth in
global fish consumption in recent decades have
been paralleled by many fundamental changes in
the ways consumers choose, purchase, prepare
and consume fish products. The globalization
of fish and fish products, propelled by increased
trade liberalization and facilitated by advances in
food processing and transportation technologies,
has expanded supply chains to the point
where a given fish may be harvested in one
country, processed in another and consumed
in yet another. International trade has helped
to reduce the impact of geographical location
and limited domestic production, broadening
the markets for many species and offering
wider choices to consumers.
Imports make up
a substantial and increasing portion of fish
consumed in Europe and North America (about
70–80 percent) and Africa (35 percent in 2017,
down from over 40 percent in previous years)
because of solid demand, including that for
non-locally produced species, in the face of
static or declining domestic fish production.
This development has allowed consumers to
access species of fish that are caught or farmed
in regions far from their point of purchase, and
it has introduced new species and products to
what were previously only local or regional
markets. Although the choices available to an
individual consumer have multiplied, at the
global level they are increasingly similar among
countries and regions. Seasonal shortages of
individual species in certain markets are also
mitigated to some extent by the international
diversification of supply sources and advances
in preservation technologies.
As a result, major
supply shocks affecting key species are likely
to affect consumption for a greater number
of people in more geographically dispersed
markets. Increasing consumer awareness of
sustainability, legality, safety and quality issues
is driving demand for traceability systems and
certification schemes of a growing range of fish
and fish products.
Urbanization has also shaped the nature and
extent of fish consumption in many countries.
Since 2007, the urban population has accounted
for more than half of the world’s people, and it
continues to grow. The number of megacities
(cities with more than 10 million inhabitants)
reached 33 in 2018, of which more than
15 are in developing countries (UN DESA,
2018). Urban inhabitants typically have more
disposable income to spend on animal proteins
such as fish, and they eat away from home more
often. In addition, the
infrastructure available
in urban areas allows for more efficient storage,
distribution and marketing of fish and fish
products. Hypermarkets and supermarkets
are developing rapidly throughout Africa,
Asia and Latin America, and fish products are
increasingly sold through these channels as
opposed to traditional fishmongers and fish
markets. At the same time, the ease of food
preparation represents an increasingly important
consideration for urban dwellers with fast-paced
lifestyles and higher demands on their time.
As a result, the demand for fish products
prepared and marketed for convenience, through
both retail and fast-food services, is rapidly
increasing. The dietary preferences of modern
urban consumers are also characterized by an
emphasis on healthy living and a relatively
high interest in the
origin of the foods they
eat – trends likely to continue to influence fish
consumption patterns in both traditional and
emerging markets.
Although fish producers and marketers
can maintain a degree of responsiveness
to the evolution of consumer preferences,
natural resource availability and biological
considerations are key in determining which
species and products are made available to
consumers. Significant expansion of aquaculture
since the mid-1980s has resulted in a sharp
increase in the proportion of farmed fish

consumed relative to wild-caught alternatives,
even if differences exist among countries and
regions in terms of preference, with a higher
share of farmed fish being consumed by Asian
countries, the main producers. At the global
level, since 2016, aquaculture has been the main
source of fish available
for human consumption,
a remarkable increase considering that this
share was only 4 percent in 1950, 9 percent in
1980 and 19 percent in 1990 (
Figure 27
). In 2018,
this share was 52 percent, a figure that can be
expected to continue to increase in the long
term. It is also important to mention that these
figures do not refer to the quantity effectively
eaten (
Box 5
). If the edible amount is taken
into account (e.g. excluding shells and other
inedible parts, which can differ also according
to traditions), capture fisheries should be
still the main source of the fish eaten due
to the higher share of farmed bivalves and
crustaceans compared with wild ones, but the
gap is narrowing.
The dominance of aquaculture in global fish
markets has significant implications for fish
distribution and consumption. Fish farming
allows greater control over production
processes than do capture fisheries, and it
is more conducive
to vertical and horizontal
integration in production and supply chains.
As a result, aquaculture has expanded fish
availability to regions and countries with
otherwise limited or no access to the cultured
species, often at cheaper prices, leading
to improved nutrition and food security.
The expansion in aquaculture production,
especially for species such as shrimps, salmon,
bivalves, tilapia, carp and catfish (including
