Tysk Syd Vestafrika. 



L. ScHULTZE (1906), der specielt har sluderet Fiskcriforholdeiie i Tysk Sydvest- 

 afrika, omtaler ikke Aalen. Paa Forespørgsel meddeler Dr. L. Schultze i Brev af 

 28. Feb. 1908 følgende: 



"Den aim. Aa\ (Aniiiiilla) findes hverken ved Kysten, i Floderne eller Flodmundinjicrne 

 etc. i Syd Vestafrika. De indfodte fanger i Floderne kun Siliirider". 



Sydafrika. 



I Sydafrika træffer vi igen Ferskvandsaal af Slægten Anguilla. Dette fremgaar 

 bl. a. af den af Bouiænger, den bedste Kender af Afrikas Ferskvandsfisk, forfattede 

 kollektive Liste over alle de fra denne Verdensdel kendte Ferskvandsfisk, (Boulenger, 

 1905). Boulenger anfører her p. 50: Anyiiilla Delalandii Kaup fra Sydafrika og An- 

 guilla bengalensis Ham. Buch. fra Natal. Den sidste er en af de brogede Anguilla- 

 Arter. 



Paa Forespørgsel har jeg gennem "the Agent General for the Cape of Good 

 Hope", London, modtaget følgende Underretning om Kapkoloniens Ferskvandsaal i 

 et Brev fra "the Acting Chief Clerk to Secretary for Agriculture", Mr. B. Mc. Millan, 

 dateret "Office of the Secretary for Agriculture", Capetown, 19de Juni 1906: 



"In reply to your letter on the al)ove subject, I am directed to inform you that the 

 undermentioned eels are known to occur in South Africa, viz.: Oi)hichlInis serpens, Anguilla 

 delalandii, Anguilla labiala, Muraena flavomarginala. Two specimens of Leptocephalus are also 

 recorded from South African waters. Tliere is no local literature on the South African Eel". 



Den fungerende Konsul for Danmark i Capetown, Mr. W. Thomas Olive, med- 

 deler i Brev af 8de Maj 1906: 



"I have the honour to inform you that through the good office of the Acting I")irector 

 of tlie (2ape Town Museum I have obtained the following information from Dr. Gii.chkist, the 

 keeper of .Marine Invertebrates and Irishes: The Eels in South Africa at present known are 

 five in number; Anguilla delalandii, Anguilla labiata, Muraena nebulosa, Muraena flavomar- 

 ginala, Ophtchthys serpens. There are therefore only two true eels. There is here no trawling 

 for eels, and no eel industry". 



Hr. Valdemar Johansen, fungerende Konsul for Danmark i Durban, Natal, 

 meddeler paa Forespørgsel i Brev af 15de Januar 1908 følgende: 



"Having made enquiries in the matter, I now beg to inform you that the fresh water 

 eels are to be found abundantly in jiractically all rivers, estuaries and lakes of Natal. 



As a matter of fact, I am told that only in the Mooi River, the eel is extinct owing to 

 the water containing minerals. The size of eels in streams and rivulets runs from 18" to 2' 

 in length, and in big rivers up to 5 and 6 feet. There are no Government restrictions as to 

 fishing of eels, they are, however, caught only rarely by the farmers and hardly ever sold 

 in the towns". 



Med Hensyn til hvilken Aaleart de natalske Aal tilhører, da angiver Boulenger 



i sin flere Gange citerede Liste over Afrikas Ferskvandsfisk p. 50, at A. bengalen^s;~Try^ 

 Ham. Buch. forekommer i Natal. A^\^- '■ '.-'//N
