It will be seen that there is no complete series of 
observations, including at least one haul in each month of 
the year in either Table I. or If. On this account and 
also with the object of eliminating as far as possible 
accidental conditions and variations, all the hauls taken 
during the Januarys in each of the years 1893-99 have 
been collected, and from these the total fish and shrimps 
caught and the averages per haul have been calculated. 
The same has been done for the other months, and the 
results are tabulated in Tables II]. and IV. III. deals 
with the portion of the ground considered in ‘lable I., and 
IV. with the portion considered in Table Ll. In Table 
VI. all the fish caught in the third quarters (July, August, 
September) of each of the years 1895-9 are collected, the 
numbers of hauls taken in each of those quarterly periods 
are given, and the average catches are calculated. In 
Table V. an attempt is made to compare the varying 
destruction of young fishes at different times and on the 
different grounds. 
We give on next page a map of the Mersey Shrimping 
Ground which has been reduced from the Liverpool Dock 
Board’s Chart of the area. It represents the extent of the 
sandbanks at low water of a spring tide ten feet below the 
level of the Old Dock Sill Datum at Liverpool. Almost 
the whole of the area shown is regularly fished over. 
More exactly, a line drawn from the N.W. extremity of 
Kast Hoyle Bank to Neweome Knoll Buoy, and from 
Newcome Knoll Buoy to the first red conical buoy in 
Queen’s Channel, defines the seaward limit of the Burbo 
Bank area. Shrimping is carried on over almost all this 
ground, the extent of which is roughly 16 to 18 square 
miles. Queen’s Channel, lormby Channel, Crosby 
Channel, Horse Channel, and the western portion of Rock 
Channel are also regularly fished. Shrimping is also
