Summary: 
Five codend designs and four behavioral-type bycatch reduction devices were tested to reduce fish bycatch in the broad squid (Photololigo etheridgei) and bottle squid (Loliolus noctiluca) trawl fishery in New South Wales, Australia. Reducing posterior circumference, increasing mesh size, and changing to diamond-shaped mesh did not improve trawl selectivity. A square-mesh codend did improve selectivity by reducing fish bycatch by 71% without reducing squid catch.
