![]() Typically, larval stages of marine species are fed live feeds such as algae, zooplankton, rotifers and artemia. ![]() To date, much work has been done to improve general husbandry and impose better health management for broodstock and larval shrimp, but the heavy dependence on live food organisms in the field of larval nutrition suggests there is still a great deal to be done before diets can be optimized for consistently good performance. It is no surprise that in the 2001 Global Shrimp OP survey by the Global Aquaculture Alliance, responding shrimp hatchery technicians gave top priority to research and development in the area of nutrition.Īs the industry moves toward greater levels of control and the use of domesticated stocks, greater demands will be made on nutrition to support optimum performance. Growing good-quality PLs requires the use of quality feeds and optimal feeding protocols. It is estimated that in 2002, more than 11,500 hatcheries produced 220,000 million PLs worldwide.Īs the supply of PLs has increased, more attention has been placed on their quality, rather than simply quantity. Hatchery production has become the principal source of PLs for the industry. Complete replacement of live feeds will require long-term R&D Microbound postlarvae diets are made using different feed-processing techniques.Ī stable supply of high-quality postlarvae (PL) is an essential requirement to guarantee the future sustainability of shrimp production.
