Abstract The spineless cuttlefish Sepiella japonica has been cultured in China in
recent years. After acclimatization to captivity, spawning induction and mating of
the broodstock, the females lay eggs attaching to the artificial substratum. Seawater temperature and salinity of hatching are 20–26 °C and 25.0–32.0 psu, respectively. The hatching period lasts for 17–26 days. Hatchlings are planktonic, with
approximately 4 mm mean mantle length (ML). The initial feedings are live cladoceran, copepods and enriched Artemia nauplii. The spineless cuttlefishes are sexually mature after 90–120 days, and mating is observed after that. Twenty-thousand
mature individuals are obtained, and survival rate from the juvenile to adult phase
is about 60 %. The mean weight of adult is 100 g. ML is 50 mm in the smallest
sexually mature individual. Spawning occurs as early as day 120. The amount of
spawned eggs is 300–500 per individual.

14.1 Importance of Sepiella japonica in the Market
Sepiella japonica Sasaki, 1929 belongs to Family Sepiidae. Russian Federation, Possiet Bay in southern Primorye and in Japan, from the Kanto region of Honshu to South
Korea, in the East China Sea as well as in the South China Sea (Jereb and Roper
2005, p. 133). S� japonica plays an important role in the fisheries of Japan, South
Korea and China. It is caught in large numbers in bottom trawls in China, and reported
under the erroneous name of Sepiella maindroni de Rochebrune, 1884 (Dong 1988;
Lu et al. 2012). A great deal of fundamental and implicational research about the species has been carried out since the 1930s, with emphasis on the following subjects:
faunal surveys, systematics, embryology and development, ecology, genetics as well
as fishery resources (Ohshima and Choe 1961; Choe 1966a, b; Adam and Rees 1966;
