Abstract / Introduction / Summary:
Information on rare rearing records of three individ- uals of Masturus lanceolatus was obtained from Shima Marineland (Mie Prefecture, Japan), which closed down on 31 March 2021. The first individual of M. lanceolatus was caught by the set net off Nakiri (34°16–17′N, 136°52–54′E), Mie Prefecture, Japan and reared from 14 to 27 December 1989. The second individual of M. lanceolatus was caught by the set net off Nakiri (34°16–17′N, 136°52–54′E), Mie Prefec- ture, Japan and reared from 28 December 1993 to 5 January 1994. The final individual of M. lanceolatus was caught by the set net off Katada (34°14–15′N, 136°49–51′E), Mie Prefecture, Japan and reared from 5 to 8 July 2005. All three reared individuals eventual- ly died. The last reared individual of M. lanceolatus had photo data left in the aquarium, and there were Mola mola and Bathytoshia brevicaudata in the same water tank. These individuals of M. lanceolatus also represent the first reliable record from Mie Prefecture.
