Economic characteristics of demand in Namibia's marine recreational shore fishery

Abstract

A sample of 626 anglers was surveyed with a questionnaire to determine the expenditures, consumer surpluses and elasticities of demand associated with the Namibian recreational marine shore fishery in 1998. Two entirely different methods of valuation, the travel cost method and contingent valuation, were applied. Results for the two methods indicate convergent validation. On aggregate, anglers spent between N$23 million and N$31 million on angling trips in Namibia during 1998, and they were willing to pay between N$24 million and N$27 million more than this for the experience. The fishery contributed between N$11 million and N$15 million to gross national income. Anglers in the fishery were found willing to pay some N$1 million annually towards conservation of the fish resource, as well as some N$340 000 annually for licences. Demand for angling experiences is generally price inelastic, suggesting that rents might be captured through donations and licence fees, without reducing angler numbers.

An economic comparison of the commercial and recreational linefisheries in Namibia

“…Using the results from the travel cost analysis carried out by Zeybrandt and Barnes (2001), it appears that the 25% decrease would be spread approximately equally among the three angler groupslocals, inland Namibians and foreigners -with a slightly larger percentage reduction in the number of foreigners and Note: The GDP generation from recreational anglers of Namibian origin, and the consumer surplus of foreign anglers, are both valued at zero for reasons discussed in the text a smaller reduction in the number of local anglers. The economic impacts of such a reduction in angling in the West Coast Recreational Area are shown in Table 8.…”

“…The consumer surpluses created for different angler groups were estimated by Kirchner et al (2000) and Stage and Kirchner 582 Zeybrandt and Barnes (2001). These are given in Table 6, with the figures inflated in order to account for the increase in price levels up to 2001.…”

“…These are given in Table 6, with the figures inflated in order to account for the increase in price levels up to 2001. Zeybrandt and Barnes (2001) estimated the consumer surpluses for the angler groups fishing in the West Coast Recreational Area using both the travel cost method and the contingent valuation method. The two methods produced fairly similar estimates.…”

“…Some limited angling also takes place farther north, at Terrace Bay and Torra Bay in the Skeleton Coast Park, and in the south near Lüderitz, as well as near Oranjemund at the South African border. Anglers target a variety of different species: silver kob (or kabeljou) Argyrosomus inodorus, West Coast steenbras Lithognathus aureti, galjoen Dichistius capensis and blacktail (or dassie) Diplodus sargus are the most important species, though some shark species are also caught (Kirchner et al 2000, Zeybrandt andBarnes 2001). The Namibian coast was once legendary for the large catches regularly made by recreational anglers, with average catches in the dozens for a normal angling day.…”
