breadth. Several streams, including the Loanan from Loch Awe, flow 
into it, and the River Inver, which, after a run of about 6 miles, falls 
into the sea at Loch Inver, flows out of it. Loch Assynt contains salmon, 
sea trout, common trout, and Salmo ferox—a variety of Salmo fario. 
No tow-net gatherings nor samples of acquatic plants were sent from 
this loch, but judging from the number and excellence of the fish con- 
tained in the loch its invertebrate fauna must be abundant, an investiga- 
tion of which might be expected to yield interesting results. Twelve 
stomachs of trout from this loch were examined and were found to 
contain numerous insect and crustacean remains as shown by the following 
tabulated statement of the results of the examination.
