the West Coast, and the ‘“ Pieter Faure” in the course of 
its investigations procured quantities of the ova of Kabeljaauw, 
Stumpnose, etc., in the open sea. So far as is generally known 
from scientific investigations, it is only the so-called “ ana- 
dromous’”’ fish that resort to rivers specially for spawing 
purposes, and none of the Zwartkops River fish belong to this 
‘category. 
(2) Spawing does not seem to take place specially in the 
upper reaches of the river, except in the case of the Barbel. 
(3) Such breeding fish do not seem to be disturbed by the 
netting operations in so far as no diminution on the whole 
appeared in the nettings throughout the year, and some fish 
when taken from the net and put into the river made first 
for the spruit in which they were caught. 
(4) No fish eggs were got in the ordinary nettings, except 
those of the Barbel. Some large eggs attached to weeds were 
found, but these proved to be the eggs of the Cuttle Fish or 
Squid. All the other eggs procured were obtained by fine 
muslin nets, and were minute, transparent and floated on or 
near the surface of the water. These were quite incapable 
of being destroyed by netting operations. 
(5) No very smali fish in the larval stages were procured in 
the nettings, though many immature fish were found. 
' (6) The fish in the Zwartkops—more especially the Steen- 
bras, which seem to feed chiefly on the “mud prawns ’— 
seem to remain as a rule in the river and do not pass out and 
in from the sea. 
(7) The fish, from the return, do not seem to have become 
scarce as a result of the netting, and it does not seem at all 
probable that they could possibly do so as a result of angling. 
(8) Floods of fresh water, it is said, sometimes clear the 
river completely of fish, killing off those that remain, but it is 
soon afterwards restocked from the sea. 
(9) No sharks were procured in the netting operations.
