General Work at the Plymouth Laboratory. 



A report by Mr. L. E. Crawshay has been published m the Journal 

 of the Association (Vol. VIII, Pt. 3) on an experiment in the keeping 

 of Salmon in sea-water at the Plymouth Laboratory, which was carried 

 out for the Duke of Bedford. Salmon smolts, which were two years 

 old when first transferred to sea-water in February, 1906, showed 

 signs of maturity in November of the same year. They were then 

 transferred to fresh water, and produced fertile ova. In March, 1907, 

 the fish were returned to sea-water, and they were again returned 

 to fresh water, and spawned in the autumn of that year. 



The smolts in the above experiment had been reared artificially in 

 the hatcliery at Endsleigh. A similar experiment is now being carried 

 on with wild smolts. 



Two reports on the Western Mackerel Fishery have been published
