Abstract

An experiment of a-sexual reproduction by fission was conducted on sea cucumber, Holothuria (Lessonothuria) verrucosa (Selenka, 1867) for 98 days. Anterior fission was observed on Day 1 with the formation of fission on the body of the sea cucumber. Initial length of 14 cm and weight of 21 g was measured at Day 1 in an aquarium under laboratory condition. Complete fission was observed on Day 7 of experiment by formation of 2 specimens; A and P. Initial length and weight for A was 4.5 cm and 3.18 g, while P was 9.5 cm and 17.30 g respectively. Increased weight for specimen A was observed on Day 20 with the first observation of the formation of anal pore. Tentacles started to form on specimen P on Day 34. Complete formation of anus on specimen A was seen on the 98th day of experiment with final weight of 3.84 g and length of 4.6 cm. Large growth of tentacle was also seen on Day 98 of the experiment with a final weight of the specimen P as 17.56 g and length as 9.7 cm.
