(c) Aa taken by several types of gear. 
(d) In connection with the trapping, various kinds of bait 
should be tried out, (Mr. Harrison has suggested that 
wooden blocks or similar parous material impregnated with 
fish oil or like "smelly H and attractive product might 
prove to be the moat durable type of bait.) A bottle with 
wick or fine tub© or tubes emitting diffusible liquid in 
water might also be experimented with, 
5. In connection with movement and migration studies i 
(a) Bettor tagging method should be developed, 
(b) In any case tagging should b© continued. 
(c) Last but not least, a sum should be set aside for bounties 
to be paid out for the first hundred tagged crabs in each 
of the two areas where tagging has so far been undertaken 
— Canoe Bay (Pavlof Bay area) and Allt&k (not to exceed 
1100 at each place). 
4. All tagged crabs should be measured, if only carapace width} 
and measuring of crabs in general should be industriously continued when- 
ever and wherever possible. Much important data regarding life history, 
growth, and age of crabs can b© obtained if only enough reliable measure- 
ments are made. Particularly desirable are measurements of crabs before 
and after moulting. Suitable live boxes or corrals should be built for 
this purpose. 
5. Egg sample® should, be saved for embryological studies and perhpps 
specimens of ovaries of crabs as well (compare karakawa* s observations).
