Thus out of 393 plaice, caught some with shrimp and some 
with fish net, 318, or 81 per cent., have recovered after being 
on an average about an hour in the tub. It does not appear 
that the one net is any more fatal than the other. It must 
be remembered however that these experimental hauls were 
of short duration and that under ordinary circumstances the 
fish trawl is down for about six hours.* Probably the great- 
est mortality is caused when the net is down for a consider- 
able time and accumulates a great weight of fish, or of 
starfishes, or gets choked with mud and rubbish, or when in 
rough weather the net full of fish is bumped heavily on the 
side of the boat in being got on board. It is astonishing 
however how even a crushed looking plaice may sometimes 
recover when put in the tub. 
* However in our district the greatest destruction of young food fishes is 
certainly caused by the shrimpers and other smaller boats fishing in inshore waters 
which in many places are the fish nurseries.
