Rather more than half the number of stomachs examined were found 

 to be empty or the food they contained could not be satisfactorily 

 determined ; fully forty-five per cent, of them were the stomachs of 

 female fish, and fifty-two per cent, males ; a few had their reproductive 

 organs so immature that it was considered doubtful whether they were 

 milters or spawners. Those found to contain food that could be 

 identified numbered two hundred and forty-three. Of these stomachs 

 about fifty-two and a half per cent, were those of female fishes, two were 

 doubtful, and the others those of male fishes, as shown in the subjoined 

 Table.

Description of the Food observed in the Stomachs of Herrings sent from 

 Loch Fyne, the Firth of Clyde, Loch Broo.n, Stornoway, 

 Anstruther, and other places. 



In describing the food observed in these herrings' stomachs, the various 

 samples from the same place or district are arranged together under the 

 name of the district and according to the date on which they were 

 examined, and for convenient reference the names of the districts 

 arranged as in Table II. 



(1) Loch Fyne Herrings. 



December, 1904. — The stomachs of seventeen herrings sent from Loch 

 Fyne were examined at this date. They all contained some food, but it 

 was so disintegrated by the digestive fluids that only in three examples 

 could the nature of it be determined, and even in these to a limited 

 extent. The food in these three stomachs appeared to consist exclusively 

 of Schizopods belonging to the Euphausiidae. Neither the species or 

 genus could be satisfactorily determined, but probably they were all 

 young Nyctiphanes, norvegica as that species is common in Loch Fyne.
