Effects of food availability on feeding and growth of cultivated juvenile Babylonia formosae habei (Altena & Gittenberger 1981)

Abstract

Juveniles of the scavenging gastropod Babylonia formosae habei (Altena & Gittenberger 1981) were kept at different ration levels in the laboratory for 30 days. Feeding behaviour and growth performance of the juveniles in relation to food availability were studied. Babylonia formosae habei juveniles were exposed to one of the four ration levels with food provided once either every 1, 2, 5 or 10 days. Higher food consumption, longer time spent on feeding and higher percentage of feeding individuals were obtained in individuals maintained at lower ration levels. Similar growth performances were observed in individuals fed once every day or every two days. A sustained production of shell was obtained in the juveniles maintained at low ration levels. At the end of the experiment, lower protein and lipid content as well as lower energy content were measured in the somatic tissue of juveniles maintained at lower ration levels. During the 30-day experiment, food availability is not a crucial factor on survival of juvenile B. formosae habei due to its physiological and behavioural adaptations developed in association with starvation

Effects of dietary protein and lipid levels and protein to energy ratios on growth performance and feed utilization of hatchery-reared juvenile spotted babylon (Babylonia areolata)

“…These differences might be that spotted babylon is a carnivorous mollusk, whereas abalone is omnivorous or herbivorous. Chen et al (2005) reported that higher food consumption and growth performances were observed in juvenile B. formosae habei fed once everyday or every 2 days and food availability is not a crucial factor on survival due to its physiological and behavioral adaptations developed in association with starvation. In conclusion, the trends in growth rate and nutritional indices provided a good indication for the response of B. areolata juveniles to the proportions of dietary protein and lipid.…”

Growth, food efficiency, and biochemical composition of juvenile spotted babylon Babylonia areolata (Link) fed on conventional trash fish and a formulated moist diet

“…The reported differences may be due to trophic levels of the spotted babylon-a carnivorous mollusk, whereas abalone are herbivorous. Chen et al (2005) reported higher food consumption and growth performances for juvenile B. formosae habei fed once every day or every two days, and food availability was not a crucial factor for survival due to its physiological and behavioral adaptations developed in association with starvation. Moreover, this study indicated that the nutritional composition of the diets affected the proximate and amino acid composition of juvenile, B. areolata.…”

“…On-growing efficiency (growth and feed efficiency) is an important criterion that must be considered for aquaculture of the target species, and therefore, it is important to understand the nutritional requirements of a species to develop effective foods. In addition, diet has also been shown to have an impact on the nutritional composition and taste of cultured animals (Britz 1996;Chen et al 2005;Woodcock and Benkendorff 2008;Chaitanawisuti et al 2010;Zhou et al 2007a, b). Consequently, determination of the biochemical composition of spotted babylon fed on different diets could be useful for optimizing the diet which in turn may help produce a high-quality product.…”

Temperature effects on the toxicity of four trace metals to adult spotted Babylonia snails (Babylonia areolata)

“…Any substantial or systematic reproduction, redistribution, reselling, loan, sub-licensing, systematic supply, or distribution in any form to anyone is expressly forbidden. Terms & Conditions of access and use can be found at http://www.tandfonline.com/page/termsand-conditions Introduction Studies on Babylonia areolata have been conducted for the last 50 years with regard to its biology and suitability as an aquaculturally important species Kritsanapuntu 1999a, 1999b;Chen et al 2005;Woodcock and Benkendorff 2008;Van Ha 2003). However, in Malaysia and globally, little information exists on the effects of metals or any toxicant on this animal.…”
