        Abstract

        Current rearing procedures for marine finfish larvae involve feeding the rotifer Brachionus rotundiformis during the initial development stages. However, B. rotundiformis is regarded as too large an initial feed type for larvae of several tropical marine fishes including groupers (Okumura, 1997; Knuckey et al., 2004), Napoleon wrasse Cheilinus undulatus (Slamet and Hutapea, 2004) and rabbitfish Siganus spp. (Juario et al., 1985). For grouper larvae, even when B. rotundiformis is used as the initial feed, massive mortality related to poor feeding is commonly observed. The small larval mouth size is widely suspected as a cause of this mortality (Okumura, 1997; Wullur et al., 2009; 2011; Hagiwara et al., 2014). This study investigated the potential use of a minute rotifer Colurella sp., isolated from an estuary in North Sulawesi, Indonesia, as a starter food for small-mouthed marine fish larvae.
