Reproductive Biology of Commercially Valuable Squid, Sepioteuthis lessoniana (Lesson, 1830) Taken as By-Catch in a Tropical Trawl Fishery
Some aspects of the reproductive characteristics of the commercially important squid Sepioteuthis lessoniana (Lesson, 1830) in the coastal waters of Mandapam, Palk Bay was studied with a view to provide possible management measures in this region. A total of 984 individuals (508 males and 476 female...
