New Zealand has the largest and longest-standing orange roughy fishery in the world. In the case of . Catch limits exceeded recommended estimates of sustainable yields for a subsequent decade and catches were estimated to have exceeded those catch limits because of burst nets, escape windows in nets and lost gear. Knowing a fish populations age distribution is important for fisheriesmanagement, but studying otoliths isnt quite as easy as counting tree rings, says Kyne Krusic-Golub. why is orange roughy so expensive Posts. Scientists believe that, though orange roughy normally live in high densities, they migrate to form even denser aggregations for the purposes of spawning. of bottom trawling. [4], The maturation age used in stock assessments ranges from 2340 years,[5][6] which limits population growth/recovery, because each new generation takes so long to start spawning.

Orange roughy are very slow-growing and do not begin to breed until they are at least 20 years old, when they are around 30 cm (12 in) in length.
