Isle Beck must have come up the Rivers Ouse and Swale and Cod Beck 
before arriving in the Isle Beck on their spawning errand. 
Burbot. — A feature of the River Derwent in the vicinity of Elvington 
lias been the occurrence of Burbot Eels during August and September ; 
anglers caught twelve Burbot weighing up to 1 lb. each during the last 
week of September. The Burbot used to be very common in the River 
Foss at York thirty years ago, but appears to have now entirely dis- 
appeared from that river. 
Flounder. — Numbers of Flounders have been taken in the River 
Derwent below Sutton dam during September, and one specimen weighing 
15 ozs. was caught in the River Nidd at Hammerton early in October. 
Barbel. — A number of Barbel have been obtained in the. Rivers 
Ouse and Wharf e during the year, but the item of most interest is the 
capture of a young Barbel 7 ins. long in the River Foss between Yearsley 
Bridge and the Union Workhouse on October 16th by Mr. William 
Dodds, of York. This fish was brought to me alive, and is being kept 
in my aquarium for further observation. I have never previously known, 
during a period of thirty years, of the occurrence of the Barbel in this 
tributary of the River Ouse. 
Roach. — The River Ouse in the vicinity of Acaster has produced 
a good number of Roach during the year, probably as the result of 
•continued stocking by the York Angling Clubs. One specimen fish 
■weighed 1 J lbs., and this was reported as having been taken near Fulford. 
Perch. — Many hundreds of Perch have been introduced into the 
.River Ouse by the York and District Amalgamation of Anglers, but it 
is curious that this species does not become very firmly established. 
I believe the explanation to be lack of suitable spawning places ; Perch 
ova is produced in long strings and requires to be interlaced amongst 
subaqueous grasses and water-loving plants, and a lack of such accom- 
modation may explain the position in regard to this fish. A specimen 
weighing 15 f ozs. was caught in the River Wharfe at Tadcaster by Mr. 
W. Lee on July 19th, and another 1 lb. if ozs. was caught in the River 
Derwent at Bubwith by Mr. W. Spindley on the same date. 
Ruffe. — Mr. D. Langstaffe draws my attention to a remarkable 
feature of the Lower Ouse, the permanent stock of Ruffe ; during the 
year many thousands have been killed by local anglers, but the supply 
seems to be as great as ever. Mr. Langstaffe suggests there must be 
something peculiar in the manner of their spawning which permits 
them to become so firmly established, and I commend the subject to our 
local biologists fdt special study. 
Gudgeon. — Another noticeable feature of the Lower Ouse (the 
"Naburn and Acaster areas being indicated) is the increase in numbers of 
Gudgeon, most of them of large size. Mr. Langstaffe states that many 
years ago they were very plentiful in the River Ouse and then became 
very scarce. On one occasion some years ago a local angler (F. Henderson) 
won a fishing match with a catch of 8 lbs. of Gudgeon numbering 120. 
Chub. — There is nothing to report in respect of Chub. 
Dace. — There have been some good catches of Dace in the River 
Ouse and Isle Beck, but none of specimen weight. 
Bleak. — This fish is extraordinarily numerous in both the Rivers 
Ouse and Foss, and affords much sport, particularly to juvenile anglers. 
North Riding (W. J. Clarke, F.Z.S.) : — Marine Fish. — Observations 
on fish have been mostly confined to the Scarborough Fish Market, where 
some interesting specimens have been landed during the year. On 
June 2nd, 1932, a Red Mullet was brought in, an uncommon fish in this 
•district. A Black Bream was trawled 12 miles E.N.E. off Scarborough 
on January 26th. Two Red Gurnards were observed among the heaps 
of the commoner Grey species on January nth, 1932. Tunnies were 
abundant off Scarborough during the summer, the first being seen on 
August 6th, 1932. Between that date and September 17th fifteen of
