The measurements show that, although hatched and reared 
under artificial conditions, the rate of growth of these fish 
has been equal to, if, indeed, it has not slightly exceeded, 
that of those hatched in the sea. Their food has consisted for the 
most part of mussels, with herring and mackerel, cut into 
small pieces, in the summer, and a very occasional meal of 
lug-worms, See 
‘Several successful trips in the motor boat, Redwing, 
during September and October to the fishing grounds off 
Niarbyl, have resulted in the addition of 113 good fish to our 
stock. So that the number of spawners in the pond is now 
close on 200. 
Lobster Culture. 
“The supply of berried female lobsters, with nearly 
ripe eggs was better during the past season than for some 
years past, 27 having been purchased from local fishermen 
between June 6th and September 14th. These yielded a total 
of 33,022 larvee, which gives an average number of 1,223 larvee 
per lobster. The successful rearing of lobster larvee involves 
the devotion of much time and labour; and though the tota 
number hatched was not very large, it was not found possible 
to deal with more than a comparatively small number of 
these. It was, therefore, decided to liberate 31,500 in the 
first stage. Of the balance of 1,522 placed in the rearing jars 
273—or about 1 in 5—were reared to the lobsterling stage 
and set free. This number is rather smaller than last year’s 
total, but it does not indicate any relaxation of effort. The 
impossibility, owing to the war, of obtaining a larger supply 
of rearing jars, and the difficulty of collecting an adequate 
supply of plankton for the daily food of the larve were 
together responsible-for the limitation in numbers. |
