84 FISH CULTURE IN BRITISH EAST AFRICA

at Jonker’s Hoek near Cape Town. 
Mr. Woosnam, the Chief Game Ranger, has recently returned 
from the Aberdare forest, and speaks enthusiastically of the 
fine appearance and development of the trout. He caught 
a few readily with a fly and returned them to the Gura river. 
The fish are larger than they would be at the same age in 
England, but similar to those that I remember of like age 
in South Africa. But he adds that the increase has not been as 
much as it should have been, and puts down this comparatively 
slow increase to the liability of deposits from the water, this 
being particularly detrimental to trout eggs. He remarked 
also that the spawning season was irregular, there being at 
the same time fish that have been spawned for some time and 
others that are far from ready yet to spawn. 
The Introduction of the Domestic Carp to 
British East Africa 
On the 9th of October last, forty-two carp fry arrived from 
Cape Town, and the greater portion of these fish are now 
flourishing in the dam at the Chief Conservator’s house, 
Nairobi. The history of the introduction of these interesting 
fish is as follows : — 
In 1908 the late Lieutenant-Governor, Mr. Jackson, in the 
course of a tour round Lake Naivasha, made tests to ascertain 
the truth of the assertion that, in this comparatively large 
lake, there were no fish of any size. His tests proved the truth 
of the assertion that there were no fish worthy of the name. 
I had long cultivated carp in Cape Colony. Details re- 
garding the successful cultivation of carp there will be found in 
an article entitled ‘ More about Carp,’ published in the Cape 
Agricultural Journal for August 1906. This article contains a 
full-page illustration of one of the carp bred at Strubenheim, 
Rosebank, near Capetown, which at two years of age 
weighed If lb. It was caught with a rod and took the fly 
readily. After Mr. Jackson’s tour round Lake Naivasha in 
1908 it was determined to attempt to introduce the Prussian 
mirror carp from the Cape. A small sum was raised by
