Trout fry at tho state fish hatchery in
KoNbury have been dying by the whole
sale Tor two months aud tho total NOR
TALLY row reaches about Il million and
a half. while the ravdEcs % disease have
mot yet bv,n stayed. There VIII be prac-
ticully no fry fnr distribution in the wa
| tors Of the state this year. for less thIn
! Iou,0oo br"uk trout fry now remain. THIS
will be a serious loss TO the fishing inter-
eSts Of tn" state. There is good reason
for cNpcctiuC an unusually satisfactory
season this year. hrIt unless the public
| water can DO stocked with fry the supply
| Of this prince Of game fish will not
| be kept up. Only the brook trout fry
have been attacked thus far, the lake
trout and brown trout showing no sign
| of disease. Tho mortality commenced III
| February. when few dead fish were first
noticed in the troushs in the hatchery
| building. 1t continued and increased UNI
til real alarm bcgaH to be felt. Tho fry,
which had Just completed absorption OF
the umbilcal sac. were found floating ON
the surface of the water, sometimes not
quite dead, with the abdomen distcndcd
and looking as if {; gas bubble had FORM
cd inside. This condition OF affairs at
length became serious that the SerV-
ices OF government expert were asked

amounts to about three gallons minute

was there any formation OF gas there

The distended appearance of those that
die is due to the body being ili-nourlshed
