OF THE CORXISH PILCHARD FISHERY.

(4) I hcit in the avoidance of certain plankton species and 

 in the taking of others, pilchards in their adult condition 

 maintain the same selective, deliberate method of feeding, 

 observed in them during their early developmental stages. 



(5) That there is a certain amount of evidence to show 

 that feeding is largely undertaken at nightfall, when the 

 surface distribution of c^ertain highly nutrient plankton species 

 reaches a maximum. 



(6) That it is largely an inherent instinct on the part 

 of the fish to seek the richest feeding grounds, that impels them 

 at times to hurriedly leave the protection of the shore at dusk 

 and to move into deeper water.
