Excerpt from Report: For the Year Ending June 30th, 1913
The new series of which this is the first number is continuous with the sixteen annual reports published by the Northumberland Sea Fisheries Committee. An arrangement has been made whereby the publication of the report will be undertaken by Armstrong College, and this will allow of the inclusion of papers other than those of purely fishery interest.
The results of an investigation on the Prawn or Norway Lobster Fishery of North Shields are described by Mr. Storrow. The Norway Lobsters are caught off the coasts of Northumberland and Durham, and the increasing importance of this branch, of the trawl fishing industry of North Shields, and the seasonal variation are indicated by a consideration of the statistics. From an examination of some 7, 000 specimens the contrast in size between the males and females, the scarcity of the females in the summer, the relatively same period of incubation as in the case of the common lobster, and similar facts have been made out. Spawning is probably biennial. The number of eggs carried varies with the size. The smallest berried specimen found measured 8 cm. The analysis has brought out also interesting details with regard to the casting season, and the influence of tides on the catches.
The experiments in lobster culture have been continued, and have shown the value of filtered water, and also of large tanks. Two young lobsters, now nearly a year old, have been successfully reared from the egg.
In the Annual Report of Proceedings under Acts relating to Sea Fisheries for 1910, issued in 1912, there appeared a paper with the title Memorandum on the Size, Sex and Condition of Lobsters. This gave the results of an investigation instituted by the Board in 1907 with a view to determining the best means of protecting lobsters.
