The Fish Hatchery. 



'•The stock of plaice collected for this year's hatching- 

 operations consisted of the survivors of the previous year's 

 stock and 67 fish captured by means of trammel or seine nets 

 in the bay, making a total of 135. This small stock was further 

 reduced by the death of a few of the fish during the winter. 

 Fertilised eggs were first seen in the pond on February 19th, 

 and the hatching apparatus was set in motion two days later, 

 when a small batch of 23,000 eggs were placed in the hatching- 

 boxes. The daily numbers of eggs increased considerably 

 during the next few days, over 100,000 being reached on 

 February 28th, ten days earlier than in 1915. Over 900,000 

 eggs, the maximum daily number for the season, were skimmed 

 from the pond on March 16th, and over half a million were 

 collected on four subsequent dates. The spawners continued 

 to yield good collections of eggs until May 2nd, when only 

 46,000 eggs and embryos were obtained.
