6. Patterns of the different sizes of mesh used in fish 
trawl and shrimp nets. The meshes are measured 
around the four sides. A ‘‘seven-inch-mesh ”’ 
therefore is one having each side of the square 
13 in. from knot to knot. The size of fish-trawl 
mesh (44 inch) in use in this district before the 
institution of the Committee, and the size (7 inch) 
now enforced by the Committee’s bye-laws are 
shown, as well as the smaller sizes (both old and 
new) used in shrimping and prawning, and the 
5 in. and 6 in. mesh used specially for a fixed 
period in each year for the capture of soles (by 
deep sea trawlers on the off-shore grounds). 
7. Two large glass vessels containing common food- 
fishes of various sizes, illustrating the average 
style of catch obtained by the nets in use before 
and since the introduction of the Committee’s 
bye-laws. Reprints on cards of statistics from 
the Superintendent’s reports are placed alongside 
and show the results of experimental hauls made 
with the two sizes of mesh (4$ inch and 7 inch). 
The four jars on the shelf above show the actual 
kinds and sizes of the fish caught by the 7 in. 
mesh, as mentioned in these statistics. The 
three jars below show those caught by the 43 in. 
mesh. The very large number of small sized 
fish destroyed by the smaller mesh will be noticed 
in these last jars. 
8. Glass vessel showing an average sample of the 
fish caught in a shrimp net in some parts of our 
district. This illustrates the destruction to 
young food-fish caused by the indiscriminate use 
of shrimp nets in localities which serve as fish
