Report on the Fisheries Department of Madras for 

 the Year Ending 3l3t March 195 3. 50 p., print- 

 ed. Developnent Department, Government of 

 Madras, Madras, India, 1951. This report 

 briefly reviews the activities of the Fisher- 

 ies Department of Madras during 1949-50, as 

 well as experiments conducted on a number of 

 species of fish. For the first time studies 

 on the productivity of chank beds and hydro- 

 biology of pearl banks were started at the 

 Tuticorin Biological Station. Results of 

 deep-sea fishing conducted at 21 centers are 

 reported to have been unsatisfactory due to 

 frequent repairs required by the motor fish- 

 ing vessels and general failure of the fish- 

 ing season, which impaired fishing operations. 

 Preservation and transportation of fish has 

 shown some development. The Development De- 

 partment is urging the canning of fish on an 

 experimental basis since consumption of can- 

 ned fish has increased and there is very 

 little imported. 



"Results of the Pismo Clam Censuses, 1948, 1949, 

 and 1950," by Robert D-. Collyer, article, 

 California Fish and Game . July 1951, vol. 37, 

 no. 3, pp. 331-4, printed. Division of Fish 

 and Game, Department of Natural Resources, 

 San Francisco, Calif, Since 1925, the Bureau 

 of Marine Fisheries has made a census of the 

 Pismo clam (Tivela stultorum ) population in 

 the Pismo Beach area during the period of 

 lowest tides each November, This report 

 covers the censuses conducted in 1948, 1949» 

 and 1950. According to the author, the re- 

 sults of the clam censuses are perturbing. 

 First, there has been an almost complete lack 

 of young clams for the past three years. Se- 

 cond, there has been a reduction each year in 

 the total number of clams found. The 1950 

 clam census showed the smallest clam popula- 

 tion since 1941. Although the present status 

 of the Pismo clams is bad, the author points 

 out that there is also reason to expect good 

 sets of young clams in the next few years 

 and that the clam population will be re-es- 

 tablished, at least temporarily.
