THE STATE OF WORLD FISHERIES AND AQUACULTURE
2020
is under way to improve this through efforts
such as those
described in the section
Illuminating Hidden Harvests, p. 176, focusing
on small-scale fisheries and ongoing FAO
work conducted on improving data quality
and reporting. Information on vessels (best
collected through registries) not only allows
countries to report on the numbers of vessels,
supporting the development of more informed
fisheries management, but also constitutes a
critical first step in recognizing and formalizing
small-scale fishery activities
and their actors at
the regional and global level.
Table 13
shows the number of vessels reported
by selected countries and territories from
each region, categorized by LOA class and
motorization status. These selected countries
and territories provide reliable data and offer
a good regional representation. While these
figures are not necessarily representative of the
average for each region, it is notable that only
7 of the 28 countries and territories shown in the
table had 200 or more vessels over 24 m LOA.
Usually, non-motorized
vessels were a minor
component of the total national fleet, with the
exception of Benin, where they constituted the
large majority, and Cambodia and Sri Lanka,
where they were up to 50 percent of the total.
Of the selected countries in Latin America and
the Caribbean, the great majority of the vessels
were
motorized, and a similar pattern was
observed with Oceania and Europe. A recent
study (Rousseau
et al.
, 2019) has confirmed that
although the small vessels in the motorized
category make up a significant share of the
global motorized fleet in numbers, they still do
not represent the largest share of total engine
power. The study also found that the large
vessels making up about 5 percent
of the fleet
constituted more than 33 percent of the total
engine power.

THE STATUS OF
FISHERY RESOURCES

Status of fishery resources
Based on FAO’s assessment,

the fraction of fish
stocks that are within biologically sustainable
levels

decreased from 90 percent in 1974 to
65.8 percent in 2017 (
Figure 19
).
In contrast, the
percentage of stocks
fished at biologically
unsustainable levels increased, especially in the
late 1970s and 1980s, from 10 percent in 1974 to
34.2 percent in 2017. This calculation treats all
fish stocks equally regardless of their biomass
and catch. In terms of landings, 78.7 percent
of current landings come from biologically
sustainable stocks.
In 2017, the maximally sustainably fished stocks
accounted for 59.6 percent and underfished stocks
for 6.2 percent of the total number of assessed
stocks. The underfished
stocks decreased
continuously from 1974 to 2017, whereas the
maximally sustainably fished stocks decreased
from 1974 to 1989, and then increased to
59.6 percent in 2017.
In 2017, among the FAO’s 16 Major Fishing
Areas, the Mediterranean and Black Sea
(Area 37) had the highest percentage
(62.5 percent) of stocks fished at unsustainable
levels, followed by the Southeast Pacific
54.5 percent (Area 87) and Southwest Atlantic
53.3 percent (Area 41) (
Figure 20
). In contrast, the
Eastern Central Pacific (Area 77), Southwest
Pacific (Area 81), Northeast Pacific (Area 67),
and Western Central Pacific (Area 71) had the
lowest proportion (13–22 percent) of stocks
fished at biologically unsustainable levels.
Other areas varied between 21 percent and
44 percent in 2017 (
Figure 20
).
The temporal pattern of landings differs from
area to area depending on the productivity of
ecosystems, fishing intensity, management and
fish stock status. In general, after excluding
