3 TASK I - SECTORAL DEMANDS: PORT 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.

 

TABLE 4: GEOGRAPHICAL DISTRIBUTION OF FISH SPECIES

 

Species Depth; distance from coast North-south distribution
Hake Demersal; densest along the continental shelf. Fairly continuous. Two slightly different hake stocks, the northern shared with Angola and the southern with South Africa.
Kingklip, monk Demersal; similar to hake. Similar to hake.
Sole Demersal; inshore. Mainly central.
Horse mackerel Throughout the water column, but densest at middle (mid-water) depths. Younger fish closer inshore at shallow depths, mature fish further out and deeper down. North of Walvis Bay, densest in the northern zone.
Chub mackerel Pelagic, mainly shallow; both in- and offshore. Central and northern.
Redeye herring Pelagic, surface-shoaling; inshore. Central and northern.
Pilchard Pelagic, surface-shoaling; inshore, usually within 50 km. Smaller central biomass from Walvis Bay to Terrace Bay; larger biomass in the northern zone. Highly variable shoaling patterns.
Anchovy Pelagic, surface-shoaling; inshore, usually within 50 km. Mostly Walvis Bay to Terrace Bay, sometimes further south and north. Highly variable shoaling pattern.
Tuna Pelagic; mainly offshore. Fast-moving and migratory; concentration around Mt Tripp Seamount in the south.
Snoek Pelagic; in- and offshore. Fast-moving and migratory; mainly central.
Squid Pelagic/mid-water; mainly offshore. Throughout the EEZ.
Shrimp Pelagic; offshore. Uncertain.
Rock lobster Demersal; close inshore, concentrated around rocky reefs. Southern coastal sites from Oyster Cliffs to Orange River.
Red crab Demersal; offshore on continental slope. Mainly central and southern.
Seals Colonies on the offshore islands and at Cape Cross. Central and southern.
Seabirds (guano) Offshore island colonies, artificial platforms at Walvis Bay and Cape Cross. Central and southern.
Seaweed Close inshore. Southern coast.
Oysters Fish farms at Lüderitz and Swakopmund. Central and southern.

 

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.
