Yet, strange to say, the trout will sometimes swim around such a body and either stupify them with fear, or hypnotize them into forgetfulness of their presence, for they will float quietly in the center of the mass, catching the minnows one by one as they need them without exciting the least fear or attention.
The minnows generally remain in fairly shallow water, and keep so closely together that a line of demarcation is made between where they are and outside, as if it had been cut with a knife along a straight edge, and in some mysterious way the fish dare not cross it, though it constantly moves along with their movements.
It will be obvious that necessarily there is much market-fishing in Lake Tahoe and its surrounding lakes.

Indeed there are large numbers of fishermen--Indians and whites--who supply the various hotels both of the Lake region and in San Francisco, Oakland, Sacramento and adjacent cities, and even as far as Denver and Salt Lake City, eastwards, and Los Angeles to the south.

These fishermen are very persistent in their work, keeping at it from early morning until late at night, though their catches are supposed to be officially regulated.
The amount of fish caught and shipped by these market-fishermen is remarkable.

In 1911 the report shows that over 22,000 pounds were sent out by express, over half of which were sent from Tallac alone.

And this does not take any account of the amount caught and eaten by private residents around the Lake, by the visitors or by the hotels.
The fish that are to be shipped are not, as one might naturally suppose, packed in ice.
