Use of the Nematode Panagrellus redivivus as an Artemia Replacement in a Larval Penaeid Diet

Abstract

Penueus vannumei larvae (P2 through M3) and early postlarvae (<24 h old postlarva) were fed diets consisting of algae‐only, nematodes (Panugrellus redivivus) plus algae or Artemia plus algae. Growth (dry biomass gain) of second and third stage protozoea larvae fed the nematodealgae diet was significantly better than that of larvae fed the Artemia‐algae diet. From the first mysis through the postlarval substage (<24 h old), growth of shrimp fed the nematodealgae diet equalled that of larvae fed the Artemia‐algae diet. All larval substages fed nematodes plus algae accumulated significantly greater biomass than those fed a diet of only algae. Survival and percent metamorphosis of larvae fed nematodes plus algae did not differ significantly from that of larvae fed either Artemia plus algae or algae alone. A nematodealgae feeding regime, which potentially yields growth, survival and metamorphosis equal to that obtained on the standard Artemia plus algae regime, is proposed for P. vannamei.

Tetraselmis chuii biomass as a potential feed additive to improve survival and oxidative stress status of Pacific white-leg shrimp Litopenaeus vannamei postlarvae

“…Meanwhile, the highest carbohydrate content was shown by T100 and T75 which contained 20.83 ± 0.65 and 21.48 ± 0.73%, respectively. The protein content (53-57%) of the treatment feed CF, T25 and T50 in this study is well within the range recommended for growth and survival of shrimp postlarvae which should be greater than 44% (Biedenbach et al 1989). The total lipid content and carbohydrate content of the formulated diet with T. chuii were also within the ranges recommended for shrimp.…”

Growth and survival of grouper Epinephelus coioides (Hamilton) larvae fed free-living nematode Panagrellus redivivus at first feeding

“…P. redivivus is a desirable live food for marine fish larvae because of its high reproductive rate (Cryan et al 1963) and small size (50 lm up to 1.5 mm in total length). Moreover, the proximate composition and amino acid profile of P. redivivus are comparable to those of Artemia nauplii (Beidenbach et al 1989).…”

“…Free-living nematode, Panagrellus spp., is acceptable to some aquarium fish and various carp species (Kahan and Appel 1975;Hofsten et al 1983, Rottman et al 1991. Panagrellus redivivus, in particular, has been tested in larval shrimps (Beidenbach et al 1989;Kumlu and Fletcher 1997) and bighead carp and Asian catfish larvae (Santiago et al 2003). P. redivivus is a desirable live food for marine fish larvae because of its high reproductive rate (Cryan et al 1963) and small size (50 lm up to 1.5 mm in total length).…”

The Effect of Live Food on the Coloration and Growth in Guppy Fish, &lt;i&gt;Poecilia reticulata&lt;/i&gt;

“…However, Artemia nauplii quality varies with the strain, location, and season [36]. Additionally, Artemia nauplii are expensive and there is variation in availability, so we proposed Moina and Panagrellus as alternative of live food for aquaculture [37] [38]. Moina are crustaceans with high quality, and fast growth and reproduction.…”
