THE FISHES OF THE RIVER HULL. 
By H. M. Foster. 
(Read January 5th, 1898.) 
HE river Hull rises in the neighbourhood of Driffield. It 
flows through a flat country, and is consequently a deep 
but sluggish stream, with banks and hed of alluvial clay. It flows 
into the Humber at Hull after a course of upwards of twenty-five 
miles. It is joined on the right bank by several natural streams, 
Cottingham Beck, Beverley Beck, Arram Beck, Watton Beck, 
Scurf Dyke and West Beck—all of which are kept clean, so as 
to afford a ready means for the surplus water to run off the land. 
On the left bank the Leven Canal joins it above Beverley, and 
Mikla Dyke at Hempholme, while Frodingham Beck, one of its 
most important feeders, runs into it some distance above West 
Beck. Frodingham Beck itself is formed by the union of two 
streams—one of which flows from Foston, and the other Old Howe 
—and is several miles in length. For convenience the river may 
be divided into four sections. 
First, from its true source to a mile above the union of West 
Beck with the Driffield Canal. In this section the stream has a more 
appreciable amount of fall. Itis consequently rapid, the bottom 
gravelly, and trout thrive. This section embraces the far-famed 
Driffield trout streams. 
The SEconpD section comprises the Driffield Canal proper as 
far as Hempholme Lock. Here the water dammed up by the 
lock is sluggish. Roach, pike, and perch abound, but bream, 
flatfish, and gudgeon, are almost entirely absent. 
The TurrD section extends from the lock to Beverley, where 
the water is tidal, and the stream ebbs and flows, but is not 
discoloured by this action. Here every species of fish found 
in the river occurs. 
The FourtTH section extends from Beverley to the Humber. 
Here the action of the tide causes the water to be more or less 
turbid. Flatfish abound, while pike and perch are almost 
entirely absent. So much for the geography of the river. 
The following species occur in the Hull:—-Perch (Perca 
Jiuviatilis), Miller’s Thumb (Coftus godio), Three Spined Stickle- 
back (Gastertosteus aculeatis), Ten Spined Stickleback (G. 
pungitius), Gudgeon (Gobio fluviatilis), Roach (Leuciscus rutilus, 
Chub (Z. cephalus), Dace (L. vulgaris), Bream (Abramis brama), 
Minnow (Z. phoxinus), Loach (Nemachilus barbatulus), Pike 
(Esox lucius), Common Trout (Sa/mo fario), Lochleven ‘Trout
