Appendices to Tenth Annual Report 
Illegal Fishing. 
Is illegal fishing prevalent in your district ? Were any prosecutions 
instituted under the Salmon Fishery Acts in 1891 1 If so, for what 
offences were they instituted, and what has been their result ? 
Artificial Obstructions to the Passage of Salmon. 
1. Mention the dams and cruives in your district, and state whether 
they are worked in accordance with the provisions of the bye-laws 
(Schedules F and G) regulating the same. 
2. Are there salmon-ladders or passes on all the dams in your district ; 
and if so, do they afford at all times a free passage to salmon wishing to 
ascend ? 
Natural Obstructions to the Passage of Salmon. 
1. Mention the natural obstructions in the shape of waterfalls in your 
district which prevent the ascent of salmon. State wdiether there are 
good and extensive spawning grounds above them, and give your opinion 
as to the best mode of opening up such spawning grounds, by attaching a 
salmon-ladder to the fall ; by blasting it ; or by a combination of the two 
methods. 
2. At present, District Boards, under the 13th section of the Salmon 
Fisheries Act of 1868, have power to attach a fish-pass to a waterfall by 
agreement with the proprietor. There is no compulsory power, similar 
to that which is conferred, under certain conditions, on Boards of Con- 
servators in England by section 49 of the Salmon Fisheries Act of 1873. 
Would you be in favour of giving such compulsory power ; and if so, 
under what conditions and restrictions ? 
Pollutions. 
Are any of the streams in your district contaminated by pollutions 1 
If so, mention them, state the nat me of the pollution, whether it is in- 
creasing or diminishing, and also whether any steps have been taken by 
the polluters to neutralise the pollution before returning the water used 
by them into the river. 
The Salmon Disease. 
1. Has the salmon disease shown itself in your district? If so, when 
did it first make its appearance ? Has it attacked kelts only, or both 
kelts and clean fish 1 ? Is it increasing or diminishing? 
2. Have you formed any opinion as to what has caused it, and what 
will prevent or cure it 1 
3. Do you think that there is sufficient provision made in the Salmon 
Fishery Acts of 1862 and 1868 to authorise District Boards to order 
their watchers to remove from the rivers and burn or otherwise destroy 
diseased fish ; or do you think that more specific authority should be 
given in a future Act? 
4. Generally, have you any remarks or suggestions to make with regard 
to the salmon disease ?
