Annual report of the Commissioners of Fisheries, Game and Forests of the State of New York . seudo-harengus)—is here in such great abundance that in the spring time when theycome from the deep cold water into that which is shallow and warm the increasedtemperature and consequent lessened supply of dissolved air kill them by thousandsand thousands. Of course our fresh-water American fish with heaviest armor is the gar or bill-fish,and the only place where we have seen a lamprey able to successfully attack thisobnoxious ganoid is just behind one of the paired fins. It might be added that this isa favorite spot for attacking many fishes, as the parasite seems to realize that here thescales are thinnest. Fortunately the gar is very rare in Cayuga Lake, although it seemsto be increasing in numbers. It is the curse of Chautauqua and Black lakes, beingthere the destructive fish foe equal to the lamprey here. We have demonstrated thatit is possible to remove gars and not injure other fishes by stretching gill nets of oneinch square mesh across their spawning places in May and FISHERIES, GAME AND FORESTS. 211 The attacks of the bowfin {Amia calva) are also infrequent, but are generally made,as described above, just back of one of the paired fins. This is another voracious fishthat is worthless to mankind, excepting as a water scavenger, and it is increasingrapidly in the waters of this State. If the lamprey would attack none but the gars,suckers, and bowfins, it would be well, for the interests of man, to protect it and aid itsincrease. Although the perch {Perca flavescens) and black bass (chiefly the small-mouth) arefairly abundant in Cayuga Lake,- they are not often found injured. They of coursebelong to the second group of fishes {Acanthopteri) named above, and the probablereasons for their immunity from attacks are given there. Of the hundreds of perchwhich we have seen taken from this lake not more than three or four bore distinct andcharacteristic scars from
