— 79 — COUNCIL-MARCH 1920-APPENDIX 



1908 — 10 about which a report has been prepared by Oscar Sund in 1910*). Ob- 

 servations as to age, size, and sexual development will be gathered, relating to the 

 commercial catches, and fishery experiments with different sorts of gear will be 

 carried out with the object of creating a technique suitable for obtaining samples 

 for scientific examination. 



It is presumed that investigations on the sprat will be continued from year 

 to year. 



D. Investigations in connection with the work at Floedeviken sea 



fish hatchery. 

 At the Floedeviken Hatchery, belonging now to the Norwegian Government, 

 the following work will be done apart from hatching of cod eggs (according to the 

 budget proposed by the director, Mr. Dannevig, for the financial term July 1920 

 to June 1921. 



1. Lobster culture experiments and investigations. 



2. Young fish investigations at the south coast of Norway (presumably in con- 

 nection with the liberation of artificially hatched cod eggs.) 



3. Researches as to age of fish at the south coast of Norway. 



E. Work relating to the methods. 



Special researches will be carried out in order to develop further the tech- 

 nique of age estimates and growth measurements. 



Owing to certain pecularities in the age distribution of the stock of. grown 

 herring belonging to the Norwegian tribe, the samples of herring scales collected 

 during a series of years are especially suited for the elucidation of certain details 

 in regard to the errors involved in the age estimates and growth calculations. 



During the coming year these questions will be subjected to a closer analysis, 

 and at the same time attempts will be made to obtain a better samphng of the 

 observations, based upon the experiences made during the last seasons with respect 

 to the stability of the age distribution of the different samples. 



Appendix VI to the Protocol of the Herring Committee.

(By Dr. Andersson, Stockholm). 



The investigations carried out in recent years with respect to the herring 

 have yielded results that at all events give some indication of the direction in which
