SHA-FISH HATCHING AT PIEL. 
By ANDREW Scorr. 
The fish hatching work carried out in the spring of 
1908 produced very similar results to those of the past 
two years. ‘The adult plaice were obtained by the trawl 
net in the closed area of Luce Bay. We have to thank 
the Fishery Board for Scotland for granting us permission 
to fish in the closed portion of this protected ground. The 
flounders were caught in the vicinity of Piel by the police 
Giimerestattoned ian the Northern division of the 
Laneashire district. 
The fish commenced to spawn on March 5th, and the 
first fertilised eggs were obtained four days later. The 
spawning period lasted for practically two months. 
During that time one million four hundred and fifty 
thousand plaice eggs were collected, and thirteen million 
five hundred thousand flounder eggs. The eggs were 
meubated in the Dannevig hatching apparatus in the 
usual way. ‘The resulting fry were afterwards liberated 
in the sea. At the end of the spawning season all the 
adult fish were set free in the channel adjoining the 
establishment.

collected, and of the fry hatched and set free on the dates
