XVIII RETOKT OF COMMISSIONER OF FISH AND FISHERIES. 



Ckaig Bkook Station, Maixk (Charle.s G. Atkins, Supekintendent). 



In the report for tlie previous year reference is made to the com- 

 inencoment of the building of a superinteudeiit's dwelling, under con- 

 tract dated March 5, 1801. This building was completed in the fall 

 and accepted from the contractor October 3. The other construction 

 work was the building of two capacious filters, one for the water sup- 

 plying the south ponds, and the other for the north stand of rearing 

 troughs and the ponds connected with it; the construction of an aque- 

 duct 800 feet long, to supply the superintendent's dwelling; the under- 

 pinning of the west eiul of the stable; the building of a winter road 

 down the hill near the north stand of troughs, and the grading of the 

 grounds near the dwelling. 



The following table presents the results of the eggs of the different 

 kinds, of salmon and trout brought over from the previous year, ending 

 June 30, 1891 : 



From these figures we may deduce the following percentages: 

 Starting with eggs as counted in winter or early spring, and counting 

 the few fish distributed in June as though they had been kept till Octo- 

 ber, we find that of all kinds 71 per cent were carried through. Leav- 

 ing out the VonBehr and Scotch sea- trout, the eggs of which reached 

 the station in exceedingly bad condition and the fry of which mostly 

 died before reaching the feeding stage, the percentage is 76; of the 

 Atlantic salmou, 80, and Loch Leven trout, 05 per cent, respectively. 

 Starting from the fry stage, the percentage of other kinds is 81, and 

 of the Atlantic salmon, 82. This season must therefore be ranked as 

 an exceedingly successful one. 



As in past years, part of the fish were fed on chopped meat and part 

 on maggots. The relative growths of the several lots furnished further 

 evidence of the superiority of live food.
