FACILITIES
3.1 SECTORAL DEMANDS FOR PORT FACILITIES: FISHING
3.1.1 THE FISH RESOURCE, EXPLOITATION AND POLICY
3.1.1.1 SENSITIVITY OF ANALYSIS
21. In spite of the past overfishing of Namibian fishing resources, and due to the
current protection policies after Independence, the long-term recovery to high yields is
good. The recovery timing is more predictable and more stable for the longer-lived white
fish (demersal) than for the short-lived oily fish (pelagic).
22. The balance between off-shore or shore-based processing is dependent on the
development of on-shore infrastructures around any of the potential fishing ports as well
as the form in which the fish is landed (frozen or on ice).
3.1.1.2 LIVING MARINE RESOURCES
23. The six major commercial species (pelagic:
pilchard, anchovy and juvenile horse mackerel; demersal: hake and horse mackerel; rock
lobster; red crab) are fully exploited. Tuna, squid and snoek are under-exploited.
Prospects for increased supply lie more with the recovery of the major fish biomass rather
than with discovery of unknown fish stocks.
3.1.1.3 PROJECTIONS OF TOTAL ALLOWABLE CATCHES
24. Under all scenarios, it is expected that
horse mackerel and red crab will sustain their present long-term catch rates (Maximum
Sustainable Yields (MSYs)), while hake will fully recover. The expected growth scenario is
that the three stocks recover, but MSY is reached only in the last phase of the planning
period (years 15-25). It has to be stressed that pilchard might never fully recover, but
equally might "explode" at any time to former levels of abundance. The long-term
total catch is estimated at 1,4 mt (1991: 0,6 mt TAC, the real annual catch for 1991 was
approx. 0,4 mt brutto (wet fish) of which approx. 80% was exported). The projections will
be pictured in tables 1 (Estimates of Long-Run Maximum Sustainable Yields For Major
Species), 2 and 3.

3.1.1.4 DISTANCE FROM COAST
25. Demersal and midwater species (hake, horse mackerel, red crab) are concentrated
50-200 km offshore, deep down and fairly evenly spread, while pelagic species (pilchard,
anchovies, juvenile horse mackerel) are concentrated 0-50 km inshore, near the surface and
in dense shoals.
3.1.1.5 DISTRIBUTION ALONG COAST
26. The Namibian EEZ and the distribution of biomass can be separated in three zones
(see table 4):
- Hake and other white fish: along the whole continental shelf;
- Horse mackerel: northern and central zones, densest in the north;
- Pilchard: central and northern zone (northern much larger and under-exploited).
Fully recovery depends on central stock which in turn is dependent on
replenishment from north;
- Anchovy: central zone, extending north and south in exceptional years;
- Rock lobster: southern coastal reef sites;
- Red crab: continental slope, mainly central and southern zones.

3.1.1.6 PRESENT FISHING CAPACITY
27. Distant-water fishing was ended on 21.03.1990 and fishing vessels must now be
locally registered.
28. The fleet comprises:
- 38 purse seiners (pelagic factories);
- 20 small trawlers, mostly old (hake);
- 20 - 25 large freezer trawlers (mostly chartered
from Spanish owners (hake, kingklip));
- 50-55 very large Russian trawlers with
mid-water gear (horse mackerel);
- 5 demersal long-liners (tuna, hake) and 15
hand-liners (various);
- 32 crayfish catchers in integrated fleets;
- 4 large Japanese crab catchers;
- A limited number of small boats.
|
29. There is excess capacity in
purse-seiners, freezer trawler, mid-water trawler and crayfish catcher categories. The
situation is pictured in the following five tables (tables 5 to 9):

* The figures for 1992 are compiled from the list of licensed vessels and include only
those vessels which appeared to have current licences at the time the list was compiled
(late 1992). The figures for 1989-1991 may additionally include vessels on licences which
were relinquished during the year in question or transferred to other vessels.
+ Small private boat owners, each with a 10 t quota. These boats were not allocated
rock lobster quotas for the 1992/93 season.
NB Vessels fishing under the ICSEAF regime up to March 1990 and not locally licensed
are excluded.
