Altogether over the months from Feb. to Aug., Mr. 
Dawson’s statistics show that the number of immature 
fish to 1 qt. of shrimps caught by means of the shrimp 
trawl on our ordinary shrimping grounds varies from 87 
to 687, the average being 310. 
Various suggestions have already been made as to a 
remedy for this most unfortunate and wasteful state of 
affairs. It has been proposed that the shrimp net should 
have at its extremity a light wooden frame bearing a wire 
sieve with long narrow meshes of such a size as would 
allow the small flat-fish to wriggle through while keeping 
back the full grown shrimps. This might do if it could 
be kept clear, but possibly it might be liable to get choked 
up and so do little good. Mr. Dawson has devised a 
modified form of shank net with a horizontal bar about 3 
ins. off the bottom to which the lower part of the net is 
attached. he theory is that as the shank frame comes 
along and disturbs the bottom the shrimps will spring 
upwards above the level of the bar and so be caught, while 
the young fish will swim along nearer the ground and so 
escape under the bar. Mr. Dawson has had this form of 
shank net made and has used it in this district and he 
reports that it ‘takes a much less number of young sea- 
fish and quite as many shrimps as the old form. In fact, 
on dirty ground more shrimps were taken, owing to a large 
proportion of the debris passing underneath the net and
