Sorry, prawn trawling is one of the most environmentally destructive of all fishing practices (usually using bottom trawls with light-weight, small bobbins or pieces of rubber on the ground rope). It is responsible for most damage done to the seabed between 250-550m in New Zealand; terrible damage is and has been done elsewhere (for almost a century).
I can't remember the true stats offhand (and these will vary from region to region), but you can expect ~90% of the total catch to be bycatch (including your octopuses). It is responsible for the extinction of one species of cirrate octopus, and near-extinction of an incirrate species in New Zealand, and a wealth of other molluscan, echinoderm and coelenterate species.
