Mean wet weight increased from 32.1 g to 342.9 g for the control group and from 58.6 g to 372.0 g for the group fed dead food. Unexpectedly, no significant differences were found between the two groups. The two groups were evaluated for differences in (1) food intake, (2) survival, (3) growth (wet weight, mantle length, instantaneous growth rate), (4) morphologic (mantle thickness in four locations, digestive gland weight), and (5) digestive gland histologic features (indices for nuclear density and relative vacuolar density).
Food for the control group consisted of live, freely swimming fish (Cyprinodon variagatus) the test group was trained to grab freshly dead fish (days 1 to 45) and then thawed, frozen fish (days 46 to 95). Squid fcan be grouped into two categories the Myopsida group which live in the shallow waters and have suckers on their tentacles.The Oegopsida group live in. Two groups of squids (n = 16 per group) were held in closed seawater systems with similar water volume, temperature, salinity, water filtration, and water flow velocities. For example, squid that secrete luminescent ink are classified in the genus Heteroteuthis of the family Sepiolidae. Usually, a school or shoal is used to refer to a large group of sea creatures. However, the group is also referred to as school or shoal. Under this order, there are many subcategories of squid. A group of squid is mostly called a squad. The effects of non-living diets on the survival, growth, and digestive gland histologic features of the bigfin reef squid (Sepioteuthis lessoniana Lesson, 1830) cultured in the laboratory were evaluated during one-half of their life cycle (95 days). Squids (Cephalopoda) Introduction Squids belong to the group of mollusks called cephalopods, which include octopi, cuttlefish, etc.
