Feeding fish larvae is expensive mo

Feeding fish larvae is expensive mostly because of the artemia costs. Although artemia is widely used and well known by the aquarists and fish farmers, costs and availability of artemia is a problem for both home use and large scale productions. There are several alternatives for larval feeding other than artemia (Santiago, et al. 2003; Delbare and Dhert, 1996). The free-living nematode Panagrellus redivivus has been recommended as a suitable food source for first-feeding fish (Reyes, et al. 2011; Schlechtriem, et al. 2004; Ricci, 2001). Panagrellus redivivus (microworm) and Radopholus similis (Banana worm) are commonly used by aquarists for the larval feeding and they are acknowledged as artemia replacement. Appropriate feeding of the larvae is very important for the further growth, development and health of the aquarium fishes (Delbare and Dhert, 1996). Suitable size and suspension of the prey in the water column is very important amongst the predator species to feed on. Any replacement of artemia salina should have the suspension and size characteristics of its predecessor. Panagrellus redivivus and Radopholus similis offers both size and suspension in water column.
