Abstract
The effects of reducing bar spaces in a generic Nordmøre grid used in an Australian penaeid-trawl fishery were investigated within an objective of maximising bycatch reduction while maintaining target catches. Compared to a conventional Nordmøre grid with 20 mm bar spaces, those with 16 and 18 mm bar spaces maintained the retained weights of school prawns,
Metapenaeus macleayi, and with no effects
on size selectivity, but caught incrementally
lower weights of total fish, which for the 16
mm grid was significant (mean reduced by
~26%). The results imply that Nordmøre
grid bar spaces can be reduced to a size approaching the width of the largest penaeids
with no commercial impacts.
