Frozen gutted or filleted are the major form of Antarctic toothfish export products and therefore possibly available throughout the year, despite the restricted annually reviewed regional catch seasons.
Demersal longlines have low levels of bycatch. All bycatch and subsequent releases of Macrourus spp. (rattails), rays and other species by operating vessels must be documented and reported to the CCAMLR. Since the gear involves no direct contact with and disturbance to the seafloor and other marine structural habitats, this method does limited damage to the marine environment.
