The impact of diet on the growth and proximate composition of juvenile whelks, Dicathais orbita (Gastropoda: Mollusca)

Use of Tuna-Cooking Liquid Effluent as a Dietary Protein and Lipid Source Replacing Fishmeal in Formulated Diets for Growing Hatchery-Reared Juvenile Spotted Babylon (Babylonia areolata)

“…These results were in agreement with the conclusions of previous studies and indicated that various types of tuna by-products gave good results in growth performance on fish and shellfish. Woodcock and Benkendorff [14] demonstrated that artificial pellets had significantly less moisture, but higher protein, glycogen, and lipid content than bivalve feeds and produced whelk flesh with significantly higher calorific energy and ash content. Dicathais orbita showed a preference in captivity for scavenging frozen bivalves, over predation on live mollusks.…”

Application of anaesthetics for sex identification and bioactive compound recovery from wild Dicathais orbita

“…obs). It is common for a varied diet to increase growth of whelks, especially if a component of carrion is included that requires less energy than live prey (Nasution and Roberts, 2004;Woodcock and Benkendorff, 2008).…”

“…However, as the abalone stock is also vulnerable to predation by the whelks (e.g. Woodcock and Benkendorff, 2008) Conversely, ethanol appears to cause muscle contraction indicating a stress response in molluscs. This has proved useful for enabling non-destructive collection of the bioactive brominated indoles produced by D. orbita.…”

“…Severe population disruption of some commercially fished muricids (whelks) has provided impetus for research into aquaculture of this family to ensure sustainable supply (Nugranad et al, 1994;Xavier Ramesh et al 1994;Gutiérrez and Gallardo, 1999;Woodcock and Benkendorff, 2008).…”

Hatching, Growth and Feed Preference of Hatchlings of<i> Volagalea cochlidium</i> (Linnaeus, 1758)

“…However, limited information on these aspects is available. Effects of different diets on growth and survival of B undatum (Nasution and Roberts, 2004), impact of diet on the growth and proximate composition of juvenile whelks Dicathais orbita (Woodcock and Benkendorff, 2008); nutritive value of Chicoreus ramosus (Xavier and Ayyakkannu, 1992) and effects of starvation on larval growth and survival of Babylonia formosae (Zheng et al, 2005) Very limited information is available on the breeding and seed production of the genus Volagalea. Reproduction, juvenile growth, consumption, effects of starvation, prey preference and capture in Hemifusus tuba has been described by Morton (1986 a, b).…”
