QUAHAVGS FROM NEW BRUNSWICK 79 



SESSIONAL PAPER No. 38a 



RECOMMENDATIONS, 



1. That the floating trays he moored in water of greater salinity and lower tem- 

 perature than that referred to above. 



2. That more favourable methods of promoting circulation and change of water 

 in the trays be adopted. These would seem to be: — - 



(a) Wider and more numerous slots. 



(6) Shallower trays, or present ones filled to about half their capacity, 

 (c) Mooring in a more open arrangement, so as to utilize the full benefit of 

 the tide. 



3. That stock be shipped in the order of its arrival. 



4. That cars be ventilated and kept at a fairly uniform temperature, about 



5. And that crowding and pressure be avoided as far as possible. 



POINTS AWAITING INVESTIGATION. 



In the course of the investigation, some biological questions and considerations 

 were suggested which might, in the interests of the fishery and science, be fully- 

 examined and settled. These may be summarized in part :— 



(1) At what age and size is the quahaug sexually mature, and do large and small 

 individuals spawn at the same time? 



(3) What proportion of the clams of the various sizes die normally every year, 

 and does death generally follow the spawning season? 



(3) What is the general effect of the retention of ova in the case of clams kept 

 for some time in the open air? 



(4) Comparison at intervals of quahaug raked early in May with those on the 

 native beds to determine the growth of the reproductive organs of the former, and 

 the general effect of storage.
