Effect of different diets on growth of the sub-adult sea cucumber Holothuria scabra

Effects of diet quantity on growth performance of juvenile sea cucumbers Holothuria scabra

“…Experiments conducted using different feed types indicated a higher growth of H. scabra juveniles fed with seaweed extract (Magcanta et al 2021). In addition, Broom et al (2021a) showed a higher growth rate in H. scabra juveniles fed with a formulated feed. In this study, the growth performance of sea cucumber juveniles was evaluated using a commercial diet and formulated diet.…”

“…scabra juveniles were obtained from the National Aquaculture Group, Alith, Saudi Arabia. They were transported to the Obhur campus fish farm of the Faculty of Marine Sciences, King Abdulaziz University according to the method described by Broom et al (2021a). At the fish farm, juveniles were kept for acclimatization (for 7 days) in fiberglass tanks filled with sand at the bottom (5 cm).…”

“…At the fish farm, juveniles were kept for acclimatization (for 7 days) in fiberglass tanks filled with sand at the bottom (5 cm). A continuous re-circulating water supply was provided to the tanks and the animals were fed with a commercial diet once daily (Broom et al 2021a).…”

“…Further, feasibility studies for sea cucumber farming have been conducted in countries such as Australia, Saudi Arabia, India, the Maldives, Indonesia, the Philippines, Madagascar and Vietnam (Purcell et al 2012). Among the sea cucumber species, Holothuria scabra (common name: sandfish) is considered a potential species for aquaculture in tropical regions due to some salient features that make it suitable for hatchery production (Broom 2021a). Many studies have been conducted to understand the fishery status, ecology and biology of H. scabra (reviewed by Raison 2008).…”

“…In aquaculture, artificial diets are essential for economically viable productivity (Qin et al 2009). However, only a few previous studies have evaluated the effects of formulated feeds on sea cucumber farming (Yuan et al 2006;Giraspy & Ivy 2008;Liu et al 2010;Broom et al 2021a). Experiments conducted using different feed types indicated a higher growth of H. scabra juveniles fed with seaweed extract (Magcanta et al 2021).…”
