SEA-FISHERIES LABORATORY. 137 
‘Some other investigations having reference to much 
needed information with respect to methods of analysis of 
shell-fish, and permissible standards of sewage contamination 
are in progress. It is hoped that a complete account of these 
may be given some time in the future. 
(1) The Cardigan Bay Mussel Fisheries. 
A report on the results of inspections made in reference 
to these shell-fisheries, and on the results of analyses, was 
presented to the Scientific Sub-Committee at the meeting 
in November, 1915. This is now reprinted as an Appendix 
to the present Annual Report. 
(2) The Mussel Fisheries in the Estuary of the Lune. 
Complaints by the Health Authorities. 
Here, also, the local conditions required considerable 
attention. During October and November repeated complaints 
were made. to the Committee and the Lancaster Health 
Local Authority. The precise genesis of these complaints 
is not very clear. In some instances, they appear to have 
arisen in consequence of the results of analyses of mussels 
taken from markets and shops, and made for the Fishmongers’ 
Company. These analytical results were then communicated 
to the local authorities. In other instances, they appear to 
have arisen as the result of investigations made by the local 
authorities into cases of enteric fever in their districts. 
Evidence on which complaints were based. 
In neither case was the evidence implicating the mussels 
satisfactory. It is unsatisfactory merely to take a sample 
of mussels from a market stall, or shop, and then to extend 
the results of the analysis to the natural bed from which 
the shell-fish were said to have come, The mussels may have 
been contaminated after removal from the fishery, and the 
statement of their place of origin may have been erroneous.
