Sepioteuthis australis, calamari, southern calamari, calamari squid and southern squid.
The only species that might be mistaken for a squid is its cousin the cuttlefish, but squid can be distinguished by the diamond shape to their body that is created by the fins that run around the entire body and the nearly transparent appearance of the body with its transparent pen, as opposed to the more opaque body of the cuttlefish with its cuttlebone. Squid have eight tentacles as well as two extendable feeding tentacles that have suckers for grasping prey. Squid can change colour rapidly and so can vary greatly in their colouring, with colours ranging from yellow-green to orange and even purple. Squid can reach up to 50cm in length, although they are mostly caught at around 20cm.
Found from Dampier in the north to the South Australian border in the south. Squid are often found in inshore waters associated with sandy bottoms, algae (seaweed) and seagrass meadows. They are found close to the bottom during the day and closer to the surface at night when they feed more actively.
Rigs and Techniques
A light spinning rod and reel outfit will do just fine when fishing for squid along with a light braided line.
The most popular method for catching squid is using a squid jig. This can be fished from the back of a boat over a weed and sand bottom or from jetties (which is the more popular option at night as squid are attracted to the lights that often illuminate jetties at night). The best retrieval is jerky, giving the squid jig time to sink after each movement as this is when the squid are most likely to strike. The speed of the retrieval can vary greatly from slow to fast and squid will pursue even a fast moving jig. Although not as common, fishing for squid with live bait does occur. One of the best live baits for catching big squid is actually smaller squid although fish can also be successful.
