temperatures and less abundant food earlier in their existence than 

 did those of the first population. The latter were probably the only 

 ones to survive to migrate to warmer waters late in November. 



Post-larval tarpon are strictly carnivorous and they are predominantly 

 piscivorous. The principal food varies with relative availability 

 of different food organisms. The size of the food consumed is 

 directly related to the size of the tarpon. Juveniles less than 

 125 mm in standard length consumed large numbers of ostracods; shrimps 

 ( Palaemonetes spp.) were eaten by tarpon longer than 75 mm in standard 



length. Fishes, mainly Gambusia affinis , were eaten by tarpon of 

 all sizes sampled. Birds appear to be the principal predators of 

 juvenile tarpon. (A. A.)

King salmon support a commercial, as well as a sport, fishery in 

 California. The estuary influences salmon populations primarily 

 because it is the migration route between the ocean and inland spawn- 

 ing areas. Little is known regarding growth of Sacramento River king 

 salmon from the time they leave the estuary as 3-inch outmigrants 

 until they begin to appear in ocean fishery landings as 20-inch fish 

 in the late summer of their second year. (B.W.)

salmon in Puget Sound, Washington. Washington Department of Fisheries 



Technical Report 10. 27 pp. 



Pink and chum salmon ( Onchorhynchus gorbuscho and 0^. keta ) were 

 collected from three widely separated onshore areas of Puget Sound 

 during April, May, and early June 1970 to determine the kinds and 

 types of organisms in the diet. Sampling areas included: Anderson 

 Island (southern Puget Sound), Port Susan (central Puget Sound), and 

 Toandos Peninsula (Hood Canal). Fish collected from the Anderson 

 Island area fed almost exclusively on harpacticoid copepods (95 percent 

 of the stomach contents). Food items consumed at the other sampling
