Pfeffer’s flamboyant cuttlefish is a small cephalopod species that grows to between 6 and 8 cm in size. Undertaking formal stock assessments (scientific assessments of the numbers of a species) for cuttlefish is generally difficult for fishery managers, as reproduction is highly variable depending on environmental conditions. Since the beginning of 2019, most boats fishing in the QLD fishery have location monitoring devices, which means authorities can ensure fishing is only taking place in areas open to fishing. While there is no on-going observer program in NSW, a research observer program has been completed but the results are currently not publicly available. There is a high risk that these factors will be detrimental to the stock status of the prawn species. The Whyalla Giant Cuttlefish aggregation really is quite unique.

Yes, the Piglet Squid is a real, living (and insanely … Cuttlefish - More than 90 species of cuttlefish live in tropical and temperate waters off of Europe, Asia, Africa and Australia. Bycatch reduction devices (BRD) and Turtle Exclusion Devices (TEDs) reduce the amount of threatened and other species that are caught and killed in fishing gear. Discarding of unwanted species is considered to be low in comparison to other trawl fisheries by the WA Government; however, reducing the amount of discarded fish and other marine animals should be a management target. Koch’s bottletail squid or the tropical bottletail squid (Sepiadarium kochi) is a species of cuttlefish found in the Indo-West Pacific from India to Japan.

Cuttlefish are generally a fast-growing, short-lived group of species that are quick to reproduce, although reproduction varies according to environmental conditions. Note: South Australian caught cuttlefish can be considered a ‘better choice’ as while there is not sufficient catch to warrant full assessment; catches are small, they are primarily caught using jig methods that have no bycatch or habitat impacts, fishing is banned in important breeding grounds, and scientific surveys have shown that populations are healthy and increasing. Cuttlefish are caught using otter trawls that operate just above the seafloor. You can find them from Indonesia up to northern Australia. Parts of the Shark Bay Marine Park area are closed to trawl fishing, protecting a significant proportion of marine habitat and providing some additional protection for endangered wildlife.

Particularly so to the large bull males, that is simply not possible at any other time. The flamboyant cuttlefish has two tentacles and eight arms. Much of the marine park areas are closed to trawl fishing, protecting a significant proportion of marine habitat. Others come from Korea, Japan and Australia. Unfortunately the QLD Government closed the observer program for all QLD-managed fisheries in 2012. Trawling has the potential to cause significant damage to marine habitats. Sepia latimanus, also known as the broadclub cuttlefish, is widely distributed from the Andaman Sea, east to Fiji, and south to northern Australia.It is the most common cuttlefish species on coral reefs, living at a depth of up to 30 m.. However, threatened species bycatch remains an ongoing issue. Cuttlefish are caught using otter trawls that operate just above the seafloor. While a NSW Government report found some shallow areas are at risk of damage from trawl activity, spatial closures and marine parks are in place that provide some degree of protection for saltmarsh, mangrove and seagrass habitats. The giant Australian cuttlefish is exactly what its name suggests – the largest оf all the cuttlefish species. Their camouflage abilities can make it quite difficult to spot these critters, but they are quite common on reefs around the world.

Sepia apama, also known as the giant cuttlefish and Australian giant cuttlefish, is the world's largest cuttlefish species, growing to 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in weight. Several species of cuttlefish inhabit NSW waters ranging from the shallow inshore reefs and weeds beds to deep offshore areas. Note: South Australian caught cuttlefish can be considered a ‘better choice’ as while there is not sufficient catch to warrant full assessment; catches are small, they are primarily caught using jig methods that have negligible bycatch and habitat impacts, fishing is banned in important breeding grounds, and scientific surveys have shown that populations are healthy and increasing. Protected species interactions occur in both fisheries; species impacted include seahorses, pipefish and sea snakes, although the available research indicates the catch is not resulting in population declines. Discarded catch is not required to be reported in these fisheries, which means that there is no information on the impact of this fishery on marine animals that have no commercial value. * Sepia apama minimum depth is based on personal observations. They can be found in coastal waters near Asia, Europe, Africa, and Australia, as well as the Mediterranean Sea and Baltic Sea. Trawl fisheries generally catch a high number of species other than those targeted, which can result in a high volume of discarding of unwanted catch.
