“…Using polymorphic analysis of genomic DNA, Yang et al (2015) recognized the presence of two genetically different populations, apparently separated by the Shandong Peninsula: one population residing in the Yellow Sea and East China Sea, and the other in the Bohai Sea. The distribution of this species is said to extend from Hainan Island in the south, along the coastal shelf of China and Korea to the Primorye coast of Russia and southern S akhalin, and the main Japanese islands including Hokkaido (Sasaki, 1929;Okutani et al, 1987;Zheng et al, 2014). Small numbers of ' O.'…”

“…obs.). Yamamoto (1942b) provides an account of an apparently similar species in Korean waters which he identified as O. variabilis typicus (Sasaki, 1929), describing it as a mud-dweller in shallow, sheltered bays, where it digs deep into the mud (see also Zheng et al, 2014). It is harvested at low tide during Spring and Autumn, using a spade-like implement or a small hand-held plough to dig the octopuses out of the mud.…”

“…The breeding season is May-June, sometimes extending into the Autumn. Females lay 120-130 large aubergine-shaped eggs of length 21-22 mm (Yamamoto, 1942b;Zheng et al, 2014). Hatchlings develop directly over 72-89 days (at 21-25°C; Zheng et al, 2014) and show the adult-like burrowing habit soon after hatching, the adults eventually reaching a total length of up to 700 mm (Yamamoto, 1942b).…”

“…In Asia, many cephalopods are important economic species for human beings. Octopods were reported the highest production for 2010, at 217,506 tones, while European production of octopuses was only 42,945 tones (Norman et al 2014), which are also one of the most important commercial cephalopod groups in China (Zheng et al 2014;Xu and Zheng 2018). Cuttlefish, such as Sepia pharaonis and Sepiella japonica, were also an important fishery in the northern part of the Indian Ocean and southeastern Asia (Nesis, Yin et al 2018).…”

Parasitic diseases and other abnormalities play critical roles in causing morbidity in the majority of Cephalopoda. However, to date, reports of cephalopod diseases from Asia are scarce and lack detailed information on the description of specific characters. This paper presents a brief overview of various pathogens and produced diseases in Asian cephalopods, including coccidiosis by Aggregata, Anisakiasis, infection by the copepods Octopicola, and other abnormalities such as edema and broken skin. The coccidian Aggregata sp. that infects the definitive host Amphioctopus fangsiao is a heteroxenous parasite transmitted through the food web. Anisakids play an important role in Asia as parasitic disease for cephalopods and it is even transmitted to humans. Concerning the infection by copepods, Octopicola sp. is the only species of the family Octopicolidae reported from North Pacific waters. Other abnormalities like edema or broken skin may have been the result of bacterial infections, so that abnormalities could cause the degeneration and death observed in A. fangsiao.

Multiple paternity was assessed in Octopus minor using microsatellite DNA markers. Octopus minor adults were captured in traps and kept in indoor cement ponds. The females spawned after several days. Ten broods (B1-B10), each containing 15 embryos and the maternal octopus, were maintained until the embryos reached the stage at which DNA could be extracted and used for genotyping. Multiple paternity was tested using five microsatellite DNA markers and the results proved the hypothesis that multiple paternity occurs in O. minor (observed in six out of the 10 broods). Analysis with GERUD software gave the minimum number of fathers and showed that four broods were sired by a single male, three were sired by two different males and three were sired by three different males. In brood B10, the number of fathers identified by the single-locus method was one fewer than that by the GERUD method. Of the six multiple paternity broods, four (66.7%) showed significant skew from equal paternal contributions, which indicated that sperm competition and/or cryptic female choice may be important for post-copulatory paternity bias in this species.
