Fatty acid enrichment of rotifers (Brachionus plicatilis) and Brine shrimp (Artemia sp.) using microcapsules containing marine oils

Abstract:Rotifers (Brachionus plicatilis) and brine shrimp ( genus genus Chirocephalus) are essential pull through feeds for devil dog fish and crustacean hatchery aquaculture worldwide. However, these have moo content of passing unsaturated fatty acids (HUFA), in ill-tempered eicosapentaenoic acid (EPA) and docosahexaenoid aicd (DHA), and essential be enriched prior being hand over to the larvae. In this experiment, microencapsulated enriching diets were hustling using a black colour sully betray liver oil which was high on HUFA, and last fed to rotifers and Artemia nauplii for 1 hour. The gut content of the rotifers and Artemia were examined at a lower place a microscope afterwards this period to observed the position of the ingested stain microcapsules. Introduction: proceed foods such as rotifers (Brachionus plicatilis) and brine shrimp (Artemia sp.) are economise essential for mass culture of larvae in the aquaculture industry, in circumstance to larvae of ma rine fish and crustaceans (Lemm & deoxyadenosine monophosphate; Lemarie, 1991; Southgate & Lou, 1995; Fernandez-Reiriz et al., 1998; Navarro et al., 1999; Han et al., 2000; Tonhein et al., 2000; Ando et al., 2004; Aragao et al., 2004; Ritar et al., 2004). The use of rotifers and Artemia is primarily because they are very well-off to use and are quick available (McEvoy et al., 1995).

Since no arranged feed formulation is provided available to completely allayer live feeds, feeding rotifers and Artemia to young fish larvae still remains essential in commercial hatchery operations (Sorgeloos et al., 2001). However, on that point is extended query of rotifers and many Artemia strains being unequal in the extremely unsaturate! d fatty acids (HUFA) eicosapentaenoic acid 20:5n-3 (EPA) and docosahexaenoid acid 22:6n-3 (DHA), which are both essential for public growth and knowledge of crustacean and marine fish larvae, and must be provided in the diet (Walford & Lam, 1987; Dhert et al. 1990; Rees et al., 1994; Southgate & Lou, 1995; Robin, 1998; Han...
