496 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, \h ton weight of trout has been 

 brought ashore by four boats in one day.* 



Of the two species of Com/o?j?<s inhabiting the Lake of Geneva (C. 

 hiemaUs, 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 J^ 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, Avere 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, 15,011.t 



* 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 

 Jurine on L. Geneva, p. 177.
