Part III. — Thirteenth Annual Report 



The report also contains elaborate papers on the Myxosporidia or 

 psorosperms of fishes, and the epidemics produced by them ; on the 

 fisheries of the Great Lakes ; on the oyster industry of New Jersey, &c. 



An important event in connection with the fisheries in the States in 

 1893 was the Chicago Exhibition, where a special department comprised 

 exhibits relating to fisheries, and conferences were held at a Fisheries 

 Congress convened for the discussion of various subjects relating thereto. 

 Many important papers dealing with questions discussed are published 

 in the last Bulletin of the Fish Commission. These include such subjects 

 as Biological Research in relation to the Fisheries, Statistics of the 

 Fisheries of the United States, Relation of Scientific Research to 

 Economic Problems ; the habits and development of the lobster, the 

 hatching of sturgeon, fish-culture, fishery laws, salmon disease, fish- 

 parasites, fishery investigations at St Andrews Laboratory, &c, &c. In 

 the Official Catalogue of the British section,* Professor E. Ray Lankester 

 gives a valuable review of the progress of fishery investigations in the United 

 Kingdom during recent years, dealing chiefly with those of the Scottish 

 Fishery Board and the Marine Biological Association. 



The Report of the Boston Fish Bureau, as usual, contains brief but 

 interesting notes about American Fisheries and the fish trade, f 



5. SWEDEN. 



As stated in previous reports, complete statistics in regard to the 

 fisheries of Sweden are not published ; but those relating to the fisheries 

 of the Bohuslan Coast are pretty full. J The total value ofjthese fisheries 

 last year was 3,193,313 kroner, of which herring yielded 1,711,467 

 kroner and mackerel 563,812 kroner. In the previous years the total 

 value of the fish caught was much less, amounting to only 2,325,397 

 kroner, the increase being chiefly due to the long continued herring 

 fishery, and the great increase is the yield of mackerel. The deep-sea 

 fishing employed 97 vessels and 990 men, and the fishing in the Kattegat 

 104 decked boats and 608 men. The mackerel fishing with, drift nets 

 was carried on in the Kattegat and Skager Rack by 381 boats, and the line 

 fishing in the North Sea employed 90 boats — a considerable increase on 

 previous years. The winter fishery for herrings was prosecuted by siene- 

 nets and set-nets, the former yielding 1,942,066 hectolitres, valued at 

 976,139 kroner, and the latter 240,775 hectolitres of the value of 661,705 

 kroner. 



As in previous years strenuous efforts were made by the Swedish curers 

 to extend and perfect the curing and preparation of herrings according to 

 the Scotch method, and the Government gave a grant of 2000 kroner to 

 defray the cost of instruction in this method. Enormous quantities of 

 fresh herrings are exported from the Bohus Provinces to Germany and 

 England to be smoked in these countries, establishments for the smoking 

 of herrings being but slowly established in this part of Sweden, although 

 several now exist, and have exported small quantities both of bloaters 

 and kippers to England and Germany. It is stated that the factories 

 for the manufacture of guano and oil from herrings have had a favourable 

 season. The guano is for the most part exported to France and the oil
