Assessing the Efficacy of Marine Copepods as an Alternative First Feed for Larval Production of Tiger Shrimp Penaeus monodon
Intensive production of marine shrimp is mainly depending on live prey in rearing of the first feeding shrimp larval stages. Commonly rotifers and brine shrimps are the primary live feed for the shrimp, and commercial shrimp production has conventionally acclimatized with this. Because, commercial scale need fast growing and high reproductive rates live pray and they mainly depend on rotifers which fulfil all the requirements. At the same time, brine shrimp Artemia can be collected in nature and stored as cysts until needed. Regrettably, still marine larviculture faces an unbalanced live feed which contains low nutritional compositions, and it reflects in shrimp larval survival and their disease resistance capability. While there is a mass production of shrimp larvae, the high and fluctuating costs of Artemia push to find an alternative live prey such as copepods (Abate et al. 2015; Drillet et al. 2008).
