Escapement was about 17 percent of the parent year, and only a few streams received an 

 adequate number of spawners. 



Qiun production of 75/000 cases accounted for 68 percent of the district's total 

 pack. Escapement was excellent and well above that of recent years for this species. 

 Many streams which norraally have only pinks had good numbers of chums. A surplus of 

 spawners provided a fall fishery in Port Jldalgo, and 158,000 good quality chum salmon 

 were taken in four days during the first week of September. There was a relatively good 

 riin and catch of Eshamy reds (fig. 13)» Satisfactory escapement did not occui- until late 

 in the season when fresh rains after a long dry period enabled schooled sockeyes to 

 ascend to the lake. 



In tlie spring. Copper River red salmon escapement and catch were normal. Observa- 

 tions indicated better than average escapement in the upper tributaries but in the lower 

 streams it was only fair. Tlie condition of the run of summer reds was also average and a 

 fair escapement was apparent. Throughout the season good weather contributed to the suc- 

 cess of the catches (fig. 1^), and the resulting pack of 5'*>000 cases was slightly under 

 the annual average of 56,000. The run, pack, and escapement of both cohos and kings were 

 about half normal. 



Research in this district is concerned primarily with developing methods of pre- 

 dicting the abundance of pink and chum salmon. Hiree methods are being explored.
