in the direction of how best to keep young fish alive at a 

 moderate cost, till they attain a fair size. At present 

 practical difficulties in feeding, and possibly in connection 

 with the movements of the water, block the way, but 

 Mr. H. Dannevig at the Hatchery of the Fishery Board 

 for Scotland has had some success with the Plaice, and 

 MM. Fabre-Domergue and Bietrix at Concarneau with 

 the Sole, and we can scarcely doubt that further investi- 

 gation and experience will show us the best methods to 

 pursue. It is at institutions like ours, where scientific 

 work is combined with the hatching, that experiments in 

 feeding and aeration can be carried out which will 

 eventually lead us to the successful rearing of the young 

 fish that we now hatch and distribute as fry. The rearing 

 of young Soles at Concarneau from the egg to a size of 

 35 mm., with a loss of only 50 per cent., is a striking and 

 encouraging fact. 



The laboratory at Piel has been occupied by several 

 scientific workers during the year. In addition to Mr. 

 Scott, who has worked there throughout the year, Mr. 

 Johnstone has paid several visits, and Mr. Cole, from 

 University College, Liverpool, spent the greater part of 

 September at Piel working at the anatomy of the Plaice. 

 Dr. H. Lyster Jameson, from the Municipal Technical 

 College at Derby, worked in the laboratory for short periods 

 during the summer, carrying out some investigations con- 

 nected with the formation of pearls in marine shell- fish. 

 Mr, H. C. Chad wick, Curator of the Port Erin Biological 

 Station, spent a couple of weeks in March studying the 

 methods of sea-fish hatching. 



Amongst the numerous visitors who came to see the ex- 

 hibition and the work going on in the establishment during 

 the year were the following : —
