In this study, … Pacific abalone, Haliotis discus hannai viscera is, reported to possess bioactivities such as antioxidative stress and anti-inflammatory. 3.3 Ecology of the species 1) [3, 4]. This species is not native to South America. In China, several abalone species are cultured, with H. discus hannai being more common in the colder water regions of northern China. The sex ratio of Haliotis discus discus collected on Jeju Island has been reported to be 1:0.8 (Kim et al. Abalone and their food, Ulva and Gracilaria. The interior surface has a peculiarly metallic luster, light bronze-green and coppery-red predominating." infections. Practical III Broodstock conditioning. Alfonso Mardones 1, Alberto Augsburger 1, Rolando Vega 1 & Patricio de Los Ríos-Escalante 2, 3. 648-658. The name abalone is probably derived from the Spanish-American word ‘aulon’ or ‘aulone’. © Copyright 2020 CAB International. In Korea, two species of abalone are found, H. gigantea, which is found on Jeju Island, and H. discus hannai, which is a cold water species, inhabiting the mainland. Research Article . The annual production of cultured abalone exceeded 100,000 t in 2013, and the Pacific abalone was the main farmed species. Aquaculture of this species is a thriving and prosperous industry in China, producing about 50,000 mt in 2010 (China Bureau of Fisheries 2011). Abalone (Haliotis discus hannai) is a marine gastropod, and an important fishery and food industrial resource that is massively maricultured in Asia, Africa, Australia and America. It is well known that abalone habitation impacts algal communications connected with the reef ecosystem, so they are often utilized for ecological research [2]. In H. discus hannai the epipodium has a brownish striped appearance. The species page of 'Haliotis discus hannai'. (2020). Bull Tohoku Reg Fish Res Lab 38: 143–153, 1977. hybridization between H. discus hannai and H. gigantea. Haliotis discus hannai was introduced into Chile specifically for commercial farming which has occurred since the late 1980s. Metal-responsive transcription factor-1 (MTF-1) is a key transcriptional regulator playing crucial roles in metal homeostasis and cellular adaptation to diverse oxidative stresses. The genetic diversity of hatchery stocks of H. discus hannai in most areas of China, however, remains unknown. It is also the most commonly cultured species of abalone in Korea. The interior surface of the shell has an iridescent appearance, being covered by a ‘nacre’ or so-called ‘mother of pearl’. or Laminaria sp.. although the species is an important mariculture shellfish in Korea. Like all other abalone, H. discus hannai is a member of a large molluscan class, the Gastropoda, and the group is characterized by having single-piece shells. In the present study, a full-length cDNA encoding the IGFBP-5 gene was cloned and characterized from the cerebral ganglion of Haliotis discus hannai. Previous work has shown that it is possible to induce spawning behavior using free radicals in tank experiments, but the stimulus for spawning in the wild is not fully understood. Synchronized control of early life in the abalone, Haliotis discus hannai INO, Haliotidae, Gastropoda [In Japanese with English summary]. Haliotis discus hannai is probably the most widely studied abalone species in the world (Hahn, 1989). (juvenile vibriosis) of abalone. Abalone (Haliotis discus hannai) is one of the most valuable marine aquatic species in Korea, Japan and China.Tremendous exposure to bacterial infection is common in aquaculture environment, especially by Vibrio sp. "This species is closely allied in all characters to Haliotis kamtschatkana but is more elongated than the typical Kamtschatkana. A sensory structure, the epipodium, is an extension of the foot that bears tentacles and projects beyond the shell edge in the living abalone. Data such as monthly frequencies of gonad development stages, GI, and CI, can provide important information to Haliotis (Haliotis) discus discus Reeve, 1846, Haliotis discus, commonly called "disk abalone," or "Edo abalone," is a species of abalone sea snail. Farms cultivating the Japanese abalone have been established in many parts of Japan, particularly in the colder water locations. Ezo abalone Haliotis discus hannai mainly spawn during stormy weather.
