APPENDIX. 
along with other species, returns of it cannot specially be given, for the 
sake of comparison. But as the S. Trutta is, with the exception of the 
char, the only Salmo inhabiting the Lake of Geneva, we may compare 
the trout of L. Neagh generally, exclusive of the salmon, with it. 
By so doing we learn that the quantity obtained in the Irish lake is 
vastly greater than that of which we have returns in the Swiss one. "We 
have no indication of the quantity taken throughout the lake. At a 
small bay, as it is called, of L. Neagh, 1 \ ton weight of trout has been 
brought ashore by four boats in one day.* 
Of the two species of Coregonus inhabiting the Lake of Geneva [C. 
hiemolis, and C. fera), we have no indication of the quantity taken of the 
former ; immense numbers of the C. fera are said to be captured during 
the three summer months at various parts of the lake ; they would ap- 
pear to be taken only in trammel or set nets. 
These will not take perhaps more than ^ of what the draught-net will 
take ; the latter is chiefly used in the fishery of the Coregonus pollan of L. 
Neagh. There are no positive returns of the quantity of Coregoni taken 
in either lake, but from the manner in which C. fera is mentioned, and 
the circumstance of the trammel-net being used, its numbers are, pro- 
bably, not at all approximate to those of the L. Neagh species, which has 
occasionally been caught in quantities with which the herring alone will 
bear comparison. Often 10, and occasionally 12, one-horse carts filled 
with these fish (about 6000 fish to each cart) are brought from the lake 
to Belfast in one morning. As the Pollan is conveyed for sale to all the 
districts around the lake, from 20 to 30 cart-loads, or from 120,000 to 
130,000 fish on the whole, may be said to be not uncommonly taken in 
the course of a fine autumnal evening or night. 
The salmon I leave to the last, as but few are now taken in the lake it- 
self, owing to the obstructions opposed to them in the river Bann, on their 
ascent from the sea. The numbers captured at the chief fishery, called the 
salmon-leap, at Coleraine, will indicate with what abundance they would 
overspread L. Neagh, were justice done to them. In the season of 1842, 
i.e. from February to the 12th of August, 13,590 salmon were taken here. 
In 1843, 21,660— and in 1844, 15,01 Lf 
* This weight in lbs. is not very much less than that taken of trout during the 
year 1802 at Geneva, both when descending the Rhine, and when the species 
was entering the lake. The number taken at Geneva in 1802 was 4055 lbs., 
and during the six subsequent years the average taken may, in round numbers, 
be said to be about double that taken at L. Neagh in this one instance. See
