in it, then put tub overboard in Douglas Harbour. 



At 9.30 a.m. (Saturday morning) all the fish were 



alive and very lively, but at 8.30 in the evening 



2 were dead and at 8 a.m. on Sunday morning 

 only one remained alive, the others having died. 

 During the time the tub had been in the water 

 it had been constantly oscillating. 



XI. May 14th, 1894. 10 miles W.J-N. from More- 

 cambe Bay light vessel — 



At 9.45 a.m. put 6 Soles, 10 to 16 inches, into the 

 tank. 9 more were added at 12.45 p m. and 



3 p.m. 



At 6 p.m. the circulation had to be stopped owing 

 to the steamer going into fresh water, the soles 

 being then all alive and very lively. 



XII. May 16th, 1894. Blackpool closed ground— 

 12 Soles, 3J to 5 inches long, 



5 Plaice, 2J to 5 inches long, 



6 Dab 3^- to 5 inches long. 



After being in tank 8J hours all the fish were alive. 

 These experiments lead to the same conclusion as those 

 we reported upon last year, viz., that under ordinary 

 circumstances the great majority of the fish taken would 

 survive if returned at once to the sea. Ground-frequenting 

 fish of sedentary habits probably stand exposure best, and 

 soles seem to be especially hardy in this respect. The 

 practical application of these experiments is that it is well 

 worth while taking some trouble to ensure that all under- 

 sized fish brought up in the trawl should be returned to 

 the sea as quickly as possible.
