Key to the F»Mn-i lies of Common Commercial Fishes 

 in the Philippines . by Augustin F. Umali, 

 Research Report 21, 47 p.i illus., printed, 

 20 cents, 1950. This report is an attengjt 

 to frame an artificial key to the families 

 of the most common commercial fishes found 

 in Philippine waters . Two sets of keys have 

 been compiled: one for the cartilaginous 

 fishes represented by the sharks, rays, and 

 their allies; and another for the bony fishes, 

 or true fishes, to which group the majority 

 of the present-day forms belong. A list of 

 the representative species and the localities 

 where each is abundantly caught is likewise 

 included. 



Larvae of Tuna and Tuna-Like Fishes from Philip - 

 pine Waters , by Charles B. Wade, Fishery Bul- 



letin 57 (From Fishery Bulletin of the Fish 

 and Wildlife Seind.ce, vol. 51) i 41 p., illus., 

 printed, 25 cents, 1951. The results of the 

 study conducted by the Philippine Fishery 

 Program of the U.S. Fish and Wildlife Serv- 

 ice of larval forms of tuna-like fishes col- 

 lected in Philippine and adjacent seas are 

 recorded in this publication. Five genera, 

 embracing four known species, of larvae pre- 

 viously unknown in the western Pacific are 

 described and illustrated: Grammatorcynus 

 bicarinatus , Neothunnus macropterus (yellow- 

 fin tuna) . Katsuwonus pelamis (skipjack tuna) 

 Euthynnus yaito . and Auxis sp. (?) . Distri- 

 bution and abundance of larvae throughout the 

 year are discussed, andtentative spawning 

 areas are defined. Some evidence of diurnal 

 vertical migration was discovered for all the 

 species except Grajiimatorcynus bicarinatus .

Observations on Gonad Development . Spawning and 

 Setting of Oysters and Starfish in Long Is- 

 land Sound . Bulletin No. 2, vol. 15, June 15, 

 1951, 2 p., free. (Available upon request 

 from the Fishery Biological Laboratory, U.S. 

 Fish and Wildlife Service, Milford, Conn.) 

 First of this year's series of special bul- 

 letins issued periodically each oyster season 

 for information of oyster growers. The bul- 

 letins will describe the progress of accumu- 

 lation of spawn in oysters during the pre- 



spawning and spawning periods, report on the 

 intensity of spawning of the oyster popula- 

 tion at different depths of Long Island Sound, 

 give the number of oyster larvae found in the 

 water, and report on the beginning and inten- 

 sity of oyster set at different sections of 

 Long Island Sound throughout the setting sea- 

 son. Observations of a similar nature will 

 also be made on the common starfish of Long 

 Island Sound, which is the chief enemy of 

 oysters in our waters. 



ARTICLE BY FISH AND WILDLIFE SERVICE AUTHORS IN OTHER PUBLICATIONS 



"Spawning and Setting of the American Oyster, 

 0. Virginica . in Relation to Lunar Phases," 

 by V. L. Loosanoff and C. A. Nomejko, article. 

 Ecology . January 1951, vol. 32, no. 1, pp. 113- 

 34, printed, single copy of periodical $2.00. 

 Duke University Press, Box 6697,' College Sta- 

 tion, Durham, N. C. In this article the au- 

 thors discuss the relation between the lunar 

 phases and the spawning and setting of the 



American oyster. According to the authors, 

 in general, "it was found that in Long Island 

 Sound no definite relationship exists between 

 the important events in the propagation of 

 oysters and the lunar phases. All of the 

 events, such as beginning of spavming, be- 

 ginning of setting, and dates of maximum sets, 

 may happen at any of the four lunar phases 

 and, therefore, under widely different hy- 

 drostatic conditions.
