![]() Another method is fishing with drift nets, which hang vertically in the sea without being anchored to the bottom and drift through the open sea. Bottom trawling aims to catch ika species directly on the seabed, while pelagic trawling aims to catch shoals in medium-deep or bottom-near waters. During the day, they gather above the sea floor. Especially when fishing with trawl nets, the natural behaviour of the animals is exploited. Since the advent of modern fishing in the 20th century, ika has been fished in large quantities. Genetic studies have confirmed that they are closely related but independent species. Until the mid-1990s, the shiro-, aka-, and kua-ika populations in Okinawa were thought to belong to the same species. The bright and slightly transparent meat is highly appreciated in Japan for the preparation of sushi and sashimi and is called by many the “King of Cuttlefish” ( ika no ōsama). The distribution of aori-ika extends from Japan to Australia and New Zealand and from Hawaii to East Africa, north to the Red Sea and south to Madagascar.Īori-ika is mostly caught near the coast and landed within a short time to be traded as fresh as possible. ![]() The origin of the name is based on the fact that the fins along the body resemble an aori (障泥), a horse harness for protection against mud. The bigfin reef squid, whose name in Japanese ( aori-ika, アオリイカ), is easily recognized by its large, rounded fins, which extend almost the entire length of its mantle. This ability is used for various purposes such as camouflage and indirect communication.Ĭlearly visible are the short white horizontal lines on the back of the male aori-ika. Another characteristic of squids is that they can change the color of their body. When fleeing from an enemy, it moves at high speed by sucking seawater between its head and body and blowing it out of the funnel at once. If a squid feels threatened, it releases its secretion and can flee hidden in the protection of the colored water cloud. This secretion is located in a muscle sack which is colloquially called ink sack. Squids are known being able to release a brown to grey-black fluid. Ika-species have ten arms, two of which serve as tentacles, which are very mobile and serve to feel or grab the prey. Ika are mainly short-lived animals that live for one to three years depending on the species and typically die shortly after spawning. The total length varies depending on the species from a few centimeters to several meters. The group of squids are adapted to life in the open water, whereas cuttlefish prefer a habitat near the bottom. There are no species found in fresh water. ![]() Ika can be found in all oceans of the world, from shallow to deep waters. ![]()
