So far there has been little indication that any of the trout caught have been cannibals--probably because they can obtain plenty of other food, and since their transfer to the loch have not been in the hungry condition in which they certainly were when they lived in the burns. On one occasion we found when carrying some of the little brown trout from one of the burns to the loch that one of the captives on the journey in the small can in which they were being carried had caught and succeeded in half swallowing another little trout half its own size. Both Mr. Malloch (see pp. 130-132 of his work mentioned above) and Mr. Hamish Stuart (_The Book of the Sea-Trout_,[33] p. 240) agree that the young of the sea-trout, if confined in a loch, grow rapidly if the feeding be good, and are as silvery as sea-trout that are fresh run. My experience in regard to the young of the sea-trout put into this loch confirms this view, as I have caught sea-trout up to nearly 2 lb. in the loch, which are in no way distinguishable from the ordinary fresh-run sea-trout. It is curious, however, that so far no sea-trout larger than 2 lb. have been caught in this loch. [Illustration: SUNSET ON THE SHORES OF LOCH CARRON. From a Photograph by Miss ALEXANDRA FRASER.] To summarise the results of these experiments, it seems clear that in order to obtain the best results the following conditions should be fulfilled: 1. _There must be a sufficient supply of the right kind of food for the fish in the loch in order that they may grow to a large size._ In order to attain this object, it is desirable that the loch should not be too high above the level of the sea. As Mr. Malloch says in the work to which I have already referred (p. 179): “Lochs over 1000 feet above sea-level, fed from snow from surrounding hills, produce little feeding until May, and owing to the cold fall off in September, thus giving the trout only four months of good feeding. On the other hand, lochs at or near sea-level produce good feeding in March, and continue to do so for three months more than their Highland brethren. It will be seen, then, that this extra time for feeding, when extended over the seven or eight years which constitute the life of a trout, easily accounts for the difference of size.” Moreover, as the same writer points out, in a loch which is very high above the sea-level, not only is the feeding-time shorter, but the food is much scarcer.
