A run of suckers is nearly always coincident with the 

 pike run, though no other rough fish appear in numbers 

 during the spawning time. 



Discussion. 



M^,. Cui.t.fr: I understood Mr. Cobb to say that the unripe female 

 came back after being thrown below the net. 



Mr. Cobb: In certain places they do; in some places they do not. 



Mr. Cullep: It mip-ht be unnecessary to pen the fish then. 



Mr, Cobb: In some instances M'here they come back we have no 

 pens. Pine River, where the water is very clear, the fish come in at night 

 but being unripe it is dropped out in the morning. In the evening it will 

 start to work its way back upstream and will get into the trap again that 

 same night. We do not pen where those conditions exist. 



Mr. Culler: That makes it very much better from the fish cul- 

 turist's standpoint. 



Mr. Cobb: Yes. 



Mr. Culler: In taking your eggs, what do you use, muck or starch? 



Mr. Cobb: Muck. 



Mr. Culler: Have you ever made an experiment with starch? 



Mr. Cobb: Yes, we have tried it, btit liked muck better. 



Mr. Adams: You spoke about the adherence of eggs in the jar. 

 Has any experiment been tried with the view of dripping automatically 

 into the jar a chemical that would not injure the egg but would be suffi- 

 cient to counteract that tendency to pack or collect? 



Mr. Cobb: I do not think so. We have never had any trouble ex- 

 cept at that one place. 



Mr. Adams: You collect your eggs in very quick water? 



Mr. Cobb: Yes. 



Mr. Adams: What gear do you use to take the adult fish? 



Mr. Cobb: Pound nets. 



Mr. Adams: You cannot anchor them in the quick water, can you? 



Mr. Cobb: We have succeeded in holding pound nets in water so 

 swift that it took two men to row a boat up to them, and in a channel 

 where we could not drive a stake — absolutely rock bottom. We ran two 

 wings to the shore, and put the big pound there. 



Mr. Adams: But your debris goes down the river. 



Mr. Cobb: We turn that to one side of the stream with boom logs 

 run out by the leads. 



Mr. Adams: Then you have to have booms on the up-side of the 

 stream — protect your trap in the same way? 



Mr. Cobb: We put a boom up above the works on an angle across 

 the river, and get the stuff away from our traps in that way. We fasten 

 two anchor lines up stream on either side of the banks, but we use no 

 stakes. In certain cases we put our pound into a frame, and anchor the 

 f ram.e and then drop the pound into it. Then we build from that to the 

 end of the two leads, which are also fastened to trees on the shore.
