16 CCMiERCIAL FISHERIES REVTEW Vol. 13, No. k 



certain conditions, such as uneven bottoms, limited dragging area, and debris caused 

 many of the drags to be shortened. 



The otter trawl was used for the purpose of comparing its fishing ability with 

 that of the beam trawl. No appreciable difference in fishing ability was noted when 

 comparison was made between the catches of 



the otter trawl and beam trawl over approx- /^^^ »»»« 



imately the same bottom; however, it ap- ^ '^ 



peared that the beam trawl was more capable ^ ;.-j 



of withstanding the rough bottom frequently 

 encountered. The beam trawl was fished 

 from the starboard davit with a scope of 

 2 to 1 in shallow water (20 to 40 fathoms) 

 and 2g- to 1 in deeper water (40 fathoms and 

 over), 



DISCUSSION ^ SHRBP CATCHES ; Four

kee Inlet, including Long Bay and Freshwater 

 Bay; Station 2 - Hood Bay, including North 



Arm and South Arm; Station 3 - Peril Strait, including Sitkoh Bay, Saook Bay, Rod- 

 man Bay, Ushk Bay, Deadman Beach, Fish Bay, and Hoonah Sound; Station 4 - Salisbury 

 Sound and Sitka area, including the open water off Kruzof Island, Nakwasina Passage, 

 Nakwasina Sound, Katlian Bay, Silver Bay, Deep Inlet, Sitka Sound, and Krestov Sound. 



Tenakee Inlet ; A total of 20 drags were made with the beam trawl and otter 

 trawl in Tenakee Inlet. The best showing of shrimp was found near the head of the 

 Inlet where 1 drag at 35 fathoms produced IO6 pounds of shrimp, 10 percent pink 

 (Pandalus borealis ) and 90 percent coon-stripe (Pandalis hypsinotis ) , on an hourly 

 basis. There were 22 large scallops taken in a beam-trawl drag 6 miles from the 

 head of Tenakee Inlet in 20 fathoms. A total of 5 drags were then made with the 

 scallop dredge, and 3 drags produced no scallops, while 2 of the 5 drags averaged 

 39 large scallops per drag. Evidently the scallops in Tenakee Inlet are few in 

 number and widely scattered, or are concentrated in areas not dragged by the John N. 

 Cobb . A set of 6 shrimp traps fished 39 hours in I5 to I7 fathoms near the south- 

 east end of a small island, 5 miles from the head of Tenakee Inlet, produced a 

 total of 209 spot shrimp ( Pandalus platyceros ) averaging 8 per pound, heads on, 

 and 256 coon-stripe, A single beam trawl drag in Long Bay netted small quantities 

 of pink and coon-stripe shrimp, 26 hard-shell male and 12 soft-shell male Dungenesa 

 crabs. From the exploration of Tenakee Inlet, the possibility of commercial shrimp 

 operation seems limited to trap fishing for spot shrimp or prawn in the gulleys 

 surrounded by rocky reefs. In Freshwater Bay 5 drags were made covering an area 

 from the head to Chatham Strait. No commercial quantities of shrimp were located; 

 46 pounds of mixed pink, side-stripe ( Pandalopsis dispar ) , and coon-stripe being 

 the largest catch of any one drag. Several ^rimp traps set near Pavlof Harbor 

 produced only one spot and 20 coon-stripe snrimp. 



Hood Bay ; Of four drags made in Hood Bay, three produced no sign of shrimp 

 and one drag netted nine pounds of pink shrimp, on an hourly basis. One drag 

 near the head of North Arm captured one small female king crab. North and South 

 Arm produced no shrimp, although two-thirds of South Arm was covered with ice and 

 could not be dragged. Five shrimp traps set in mid-channel from Cabin Point to- 

 wards the entrance produced no shrimp, and one to five starfish were found in each 

 trap. Throughout this survey when starfish were found in abimdance , a mariced ab- 

 sence of shrimp was noted.
