extract thickening agents such as alginate, agar 
and carrageenan. In medicine, seaweeds can be 
used to treat iodine deficiency and as a vermifuge 
(Marine Biotechnology, 2015). Research is also 
exploring the use of seaweeds as a salt substitute 
and in the industrial preparation of biofuel.

THE STATE OF WORLD FISHERIES AND AQUACULTURE 
2020
Food loss and waste
11
Global food loss and waste is a serious issue and 
is the focus of Sustainable Development Goal 
(SDG) Target 12.3, which aims at halving wastage 
by 2030. Proper handling, hygiene and respect 
of the cold chain from harvest to consumption 
are crucial to preventing loss and waste and 
preserving quality. In fisheries and aquaculture, it 
is estimated that 35 percent of the global harvest 
is either lost or wasted every year. In most 
regions of the world, total fish loss and waste lies 
between 30 percent and 35 percent. Wastage rates 
have been estimated to be highest in North 
America and Oceania, where about half of all 
fish caught is wasted at the consumption stage. 
In Africa and Latin America, fish is mainly lost 
because of inadequate preservation infrastructure 
and expertise, with Latin America being the least 
wasteful region (under 30 percent of total fish 
lost).
Fish losses, in quantity and quality, are 
driven by inefficiencies in value chains. 
Despite technical advances and innovations, 
many countries – especially the least developed 
economies – still lack adequate infrastructure, 
services and practices for adequate onboard 
and on-shore handling and for preserving 
fish quality. Key deficiencies relate to access 
to electricity, potable water, roads, ice, cold 
storage and refrigerated transport. Effective fish 
loss and waste reduction requires appropriate 
policies, regulatory frameworks, capacity 
building, services and infrastructure, as well 
as physical access to markets. Understanding 
how these different factors interact in a given 
context is important, with the interaction and 
priorities varying according to location, species, 
climate and culture. It should be emphasized 
that reducing fish loss and waste can lead to 
a reduction in pressure on fish stocks and 
contribute to improving resource sustainability 
as well as food security.

Food waste refers to the decrease in the quantity or quality of food 
resulting from decisions and actions by retailers, food service providers 
and consumers. An example of “waste” in fisheries is “discards”, 
whereby fish are thrown away at sea. Food loss is the decrease in the 
quantity or quality of food resulting from decisions and actions by food. 
A reduction in quality usually leads to a reduction in nutritional value, 
economic value, or food safety issues. Information on the food loss and 
waste in fish value chain can be found on an FAO web page devoted 
to this topic (FAO, 2020a).
FISH CONSUMPTION 
For over 60 years, global apparent food 
fish consumption
12
has increased at a rate 
significantly above that of world population 
growth. In the period 1961–2017, the 
average annual growth rate of total food 
fish consumption was 3.1 percent, outpacing 
annual population growth rate (1.6 percent). 
In the same period, the average annual growth 
rate of total food fish consumption (i.e total 
supply, see 
Box 5
) also outpaced that of all 
other animal proteins (meat, eggs, milk, etc.), 
which increased at an average of 2.1 percent 
per year, and of all terrestrial meat combined 
(2.7 percent per year) or by individual groups 
(meat of bovine, mutton and goat, pig), with 
the notable exception of poultry, which grew at 
4.7 percent per year. In per capita terms, food 
fish consumption rose from 9.0 kg (live weight 
equivalent) in 1961 to 20.3 kg in 2017, at an 
average rate of about 1.5 percent per year, while 
total meat consumption grew by 1.1 percent per 
year in the same period. Preliminary estimates 
for per capita fish consumption in 2018 currently 
stand at 20.5 kg. The expansion in consumption 
has been driven not only by increases in 
production, but also by a combination of many 
other factors. These include: technological 
developments in processing, cold chain, 
shipping and distribution; rising incomes 
worldwide, which strongly correlate with 
increased demand for fish and fish products; 
reductions in loss and waste; and increased 
awareness of the health benefits of fish 
among consumers. 
Given the wide diversity of aquatic life, 
the nutritional composition of fish varies 
significantly according to species and the way 
in which they are processed and marketed. 
Although they are not calorie dense, fish and fish 
products are appreciated and important for their 
high-quality proteins and essential amino acids,

All food fish consumption statistics reported in this section refer to 
apparent consumption derived from FAO Food Balance Sheets (FBS) of 
fish and fish products as at March 2020. All data are expressed in live 
weight equivalent. Consumption data for 2017 should be considered 
preliminary. These values could differ slightly from those to be released 
in the FBS section of the 
FAO Yearbook of Fishery and Aquaculture 
Statistics 2018
, and in the FishStatJ workspace in mid-2020. The 
updated data can be accessed through an FAO web page (FAO, 
2020b), as can all editions of the yearbook (FAO, 2020c).
