Definition of "squeteague"

Then there came a reg'lar terror of a sou'wester same as you don't get one summer in a thousand, and blowed the shanty flat and ripped about half of the weir poles out of the sand. We spent consider'ble money getting 'em reset, and then a swordfish got into the pound and tore the nets all to slathers, right in the middle of the squiteague season.

1913, Joseph C[rosby] Lincoln, chapter I, in Mr. Pratt’s Patients, New York, N.Y., London: D[aniel] Appleton and Company

The Injuns get to Naturmitgefuhl by the metaphor of a family: if you don't throw the roe-plump squeteague back, that is a sort of nepoticide.
