Characteristics and economic contribution of a developing recreational fishery in southern Angola

Abstract

The characteristics and contribution of a developing recreational fishery to the local, regional and national economy of Angola were evaluated in 2006. Annual angling effort was 13 435 h, while the estimated total catch of the three target species [leerfish, Lichia amia (L.), west coast dusky kob, Argyrosomus coronus (Griffiths & Heemstra) and shad, Pomatomus saltatrix (L.)], was 5913 fish with a mass of 27 975 kg. Catch per unit effort (CPUE) for all teleost species combined was 0.44 fish per angler h )1 and 2.08 kg per angler h )1 . Total harvest of the three species was 576 fish with a total mass of 2221.6 kg. The total contribution of this recreational fishery (mostly anglers from South Africa)

Are guitarfishes the next sawfishes? Extinction risk and an urgent call for conservation action

“…Very little is known about the spatial ecology of guitarfishes to inform conservation, and what is known is largely limited to the developed world (Farrugia et al 2011, White et al 2014b. In addition to the potential to provide significant economic benefits to local communities in LDCs (Potts et al 2009), recreational fisheries may offer opportunities for gaining crucial knowledge of guitarfish spatial ecology, particularly for larger species that may be both the most threatened and the most attractive to anglers. Over 6000 Acroteriobatus annulatus were tagged in South African sport fisheries between 1984 and 2011, revealing important information such as a maximum distance travelled of 726 km.…”

A spatio-temporal assessment of theTrachinotus botlashore-fishery in KwaZulu-Natal, South Africa

“…It is now recognised that most of the motivation to go angling is not necessarily directly related to the size of harvest. For example, the willingness of participants to spend large sums of money for the opportun ity to catch a single prized fish was illustrated in a recent economic evaluation of an Angolan recreational fishery (Potts et al 2009). The total contribution of the recreational fishery to the local economy in 2006 was US$1 007 per harvested fish and US$243 per harvested kg (Potts et al 2009).…”

Similarly, the coastal community of St Lucia in KwaZulu-Natal (KZN), South Africa, received approximately US$1.2 million from expenditure directly related to recreational fishing in 2001 (Mann et al 2002a).…”

“…Declines in population sizes of recreationally important species, as inferred through decreases in angler catch rates, have sometimes been disregarded by both anglers and fisheries managers because of a widespread perception that recreational fishing is a benign activity (Cooke and Cowx 2006). However, dramatic declines in catches and catch rates in the South African, Namibian and Angolan inshore fisheries as a direct result of recreational fishing pressure have been observed , Holtzhausen and Kirchner 2001, Potts et al 2009) and have necessitated direct management intervention (Palmer et al 2008).…”

Catch-and-release angling mortality of south-eastern AustralianPomatomus saltatrix

“…While there is substantial interpopulation variation among biological traits (reflecting diverse environmental conditions), all stocks of P. saltatrix undertake fairly defined annual inshore spawning migrations (Juanes et al 1996). Such movements render them vulnerable to various inshore fisheries, including recreational hook and line off Australia (Ayvazian et al 2002), eastern USA (Fabrizio et al 2008) and southern Africa (Potts et al 2009). …”
