shiner

These experiences were very memorable and valuable to me -- anchored in forty feet of water, and twenty or thirty rods from the shore, surrounded sometimes by thousands of small perch and shiners, dimpling the surface with their tails in the moonlight, and communicating by a long flaxen line with mysterious nocturnal fishes which had their dwelling forty feet below, or sometimes dragging sixty feet of line about the pond as I drifted in the gentle night breeze, now and then feeling a slight vibration along it, indicative of some life prowling about its extremity, of dull uncertain blundering purpose there, and slow to make up its mind.

Paddling over it, you may see, many feet beneath the surface, the schools of perch and shiners, perhaps only an inch long, yet the former easily distinguished by their transverse bars, and you think that they must be ascetic fish that find a subsistence there.

There have been caught in Walden pickerel, one weighing seven pounds -- to say nothing of another which carried off a reel with great velocity, which the fisherman safely set down at eight pounds because he did not see him -- perch and pouts, some of each weighing over two pounds, shiners, chivins or roach (Leuciscus pulchellus), a very few breams, and a couple of eels, one weighing four pounds -- I am thus particular because the weight of a fish is commonly its only title to fame, and these are the only eels I have heard of here; -- also, I have a faint recollection of a little fish some five inches long, with silvery sides and a greenish back, somewhat dace-like in its character, which I mention here chiefly to link my facts to fable.

From a hilltop you can see a fish leap in almost any part; for not a pickerel or shiner picks an insect from this smooth surface but it manifestly disturbs the equilibrium of the whole lake.
