A resume is given in his Eeport, and 

 Present extent the extent to which net and coble fishing is carried on at the 

 Coble Fishing, present time is shown in Appendix L, together with the names of 

 proprietors and tacksmen. 



Answers were received, by the Inspector, to the different queries 

 regarding the salmon fisheries, issued annually to Clerks of all 

 District Fishery Boards, and to those proprietors or their agents 

 who hold rights of salmon fishing over an entire district or series of 

 districts. The replies, which form Appendix II. to the Inspector's 

 Eeport come, apparently, from eveiy district possible, and form the 

 most complete return yet received.

Salmon 



Marking 



Results. 



Mr. Calderwood furnishes, in Appendix III., a second paper on 

 the results of the salmon marking operations which have been 

 conducted for some years. Since the publication of his first paper 

 on this subject sixty- two additional recaptures have been made, 

 many of which are of considerable interest. Several fish marked as 

 grilse have been recaptured as salmon, which should reduce the 

 belief still held by some engaged in the salmon fisheries industry, 

 that the grilse is not a young salmon ; moreover, it is shown by 

 the recaptures that grilse kelts of one spring may return as clean 

 salmon either in the summer of the same year, or as clean spring 

 fish in the following year, and that this divided migration persists 

 also in later stages of the salmon's existence. In treating the Tay 

 recaptures, Mr. Calderwood has, by selecting important cases, been 

 able to construct a diagram showing approximately the migrations 

 and growth of the Tay (female) fish up to its seventh year. 



As arising from the marking of salmon and the collecting of 

 particulars respecting the length and sex of fish, papers are also 

 furnished on the measurements of unspawned salmon and grilse, 

 Appendix IV. ; the proportion of the sexes during the winter and 

 spring months, Appendix V.: and on the relative numbers of 

 grilse and salmon in the lower Tay during the spawning season, 

 Appendix VI. With regard to the proportion of the sexes, it 

 appears that in different parts of Scotland opposite conditions 

 obtain. In many rivers in the centre and south of Scotland female 

 salmon appear to be more numerous than males, whereas in the 

 north, in the counties of Caithness, Sutherland, and Eoss, males 

 seem to be in excess. 



In Appendix VII. is found a description, with illustrations, of the 

 largest salmon pass which has as yet been attempted in Scotland. 

 This new structure, which is now in operation, is at the Inver- 

 moriston Fall in the Ness District. The difference in level between 

 the pool above and the pool below the Fall is 24 feet, and the 

 gradient of the Pass is 1 in 21*7. 



A note on the Bull Trout of the Tay, including an analysis of the 

 flesh of this fish, forms Appendix VIII.
