 This paper, the third in a series on the formation 

 of drip in fish, reports on (1) a comparison of the 

 composition of free drip and centrifuge drip taken 

 from paired lots of frozen Pacific cod fillets and (2) 

 changes in the composition of drip taken from cod 

 fillets after varying periods of storage at 0° and 

 20° F. 



Vol. 3, No. 1. Occuri'ence of pomfret (Brama 

 japonica) in the Northeastern Pacific Ocean. 

 By Charles R. Hitz and Robert R. French. 

 December 1965, pp. 1-7, 5 figs., 4 tables. 

 ABSTRACT 

 During investigations by the Bureau of Commer- 

 cial Fisheries in the Northeastern Pacific, pomfret 

 were found to be widely distributed, from north of 

 Latitude 12° North and from Longitude 175° East 

 to the coast of North America. Pomfret were taken 

 mainly during August and September at surface- 

 water temperatures of 11° to 14° C. The catches 

 by the Bureau and others suggest that pomfret may 

 occur in certain areas of the Northeastern Pacific 

 in commercially harvestable quantities

 fatty acid pattern of muscle and organ lipids 

 of the rainbow trout (Snimo Gairdneri) . Bv 

 Werner G. Knii^prath and James F. Mead. 

 December 1965, pp. 23-27, 2 tables. 

 ABSTRACT 

 Fatty acids of the total lipids of 2 groups of rain- 

 bow trout kept at different water temperatures were 

 analyzed. 



Both muscle and organ lipids tended to incor- 

 porate more highly unsaturated fatty acids at 

 lower temperatures. The specific fatty acids that 

 were incorporated, however, differed in the 2 types 

 of tissues. 



Vol. 3, No. 1. Costs and earnings of tropical 

 tuna vessels based in California. By Roger E. 



Green and Gordon C. Broadhead. December 



1965, pp. 29-45, 15 figs., 8 tables. 

 ABSTRACT 

 This paper presents a method of estimating earn- 

 ings of purse seiners, taking into account effects of 

 vessel size and various tuna prices and rates of 

 harvest on the economics of purse .seining. Esti- 

 mations are made of earnings to crew and net profit 

 or loss to owners for a selected range of prices and 

 catch rates for vessels in the size range 100 to 500 

 tons capacity. Optimum vessel sizes are examined 

 from standpoints of both owner and crewman. 



Vol. 3, No. 1. Amino acid composition of the 

 alewife (Alosa pseudoharengHs) . By Mary 

 H. Thompson and Robert N. Farragut. De- 

 cember 1965, pp. 47-53, 4 figs., 3 tables. 

 ABSTRACT 

 The amino acid and related compound of alewife 

 samples collected from Lake Michigan was deter- 

 mined on a seasonal basis. Significant seasonal var- 

 iations in total available nitrogen, ninhydrin-positive 

 compounds, and protein amino acids are discussed 

 in relation to the reproductive cycle of the alewife. 

 Results are reported in terms of the concentration 

 of the various nitrogenous compounds present in 

 the whole fish.
