Abstract

Rotifers are the best live food for feeding fish and shrimp larvae in their early stages. For rotifers live feed, certain wild animals were now harvested and fed to the larvae and brooders. Still, unfortunately, the collected wild live feeds are forming a way to the entry of pathogenic organisms, which can cause diseases to the cultivable species. Additionally, gathering live feeds from the wild is a labour-intensive task, and it is never sure that the requisite organisms will be available in the appropriate quantities. In this context, the current review focused on the rotifer and the methods for collecting, morphologically identifying, and mass-producing it. A range of alternate uses for rotifers can also be investigated. For a nation like India and other nearby countries, cultivating live feeds is essential, especially the culture of rotifer species in captivity. Unfortunately, due to a lack of adequate cultural technology and guidance and a lack of brood-stock facilities, there are currently viable technologies for the comprehensive production of the marine rotifer in the aquaculture business, especially in India. This necessitates the development of culture and technology for each conceivable species of marine rotifer, as well as the preservation and distribution of a pure culture of that species to farmers, researchers, and aquaculture practitioners across the country. Possibilities for high-density cultivation, microbial problems, and associated nutrient requirements have all been discussed. Keywords: Rotifer. Live feed. Brachionus angularis. Colurella. Nutrition.
