A comparison of various seaweed-based diets and formulated feed on growth rate of abalone in a land-based aquaculture system
(Springer, 2007)The effects of different diets on growth in the cultured South African abalone, Haliotis midae (Linnaeus), was investigated. Growth of juvenile Haliotis midae was monitored on a commercial abalone farm over a period of ... -
Determining the most appropriate feeding regime for the South African abalone Haliotis midae Linnaeus grown on kelp
(Springer Verlag, 2008)Beach-cast kelp (the most widely used feed for commercially grown South African abalone) is plentiful during winter months when periodic storms cause kelp to wash ashore. During summer, however, this resource is not ... -
Effects of herbivore grazing on the physiognomy of the coralline alga Spongites yendoi and on associated competitive interactions
(National Inquiry Services Centre (NISC) and Taylor & Francis, 2008)The territorial gardening limpet Scutellastra cochlear occurs along the south and southern west coasts of South Africa, while one of its primary food items, the encrusting coralline alga Spongites yendoi, extends much ... -
Effects of wild and farm-grown macroalgae on the growth of juvenile South African abalone Haliotis midae Linnaeus
(Taylor and Francis, 2011)The effect of various macroalgal diets on the growth of grow-out (> 20 mm shell length) South African abalone Haliotis midae was investigated on a commercial abalone farm. The experiment consisted of four treatments: fresh ... -
Growth of market-size abalone (Haliotis midae) fed kelp (Ecklonia maxima) versus a low-protein commercial feed
(Taylor & Francis, 2008)The growth of grow-out abalone fed on kelp, with ca. 10 % dry weight protein content, was compared with that of those fed a new ,ca. 26 % protein, commercial feed in a flow-through system on a South African west coast ... -
The growth of post-weaning abalone (Haliotis midae Linnaeus) fed commercially available formulated feeds supplemented with fresh wild seaweed
(National Inquiry Services Centre (NISC) and Taylor & Francis, 2008)The effect of five formulated feeds, supplemented with fresh wild seaweed on the growth of post-weaning juvenile abalone (6 - 20 mm shell length), Haliotis midae Linnaeus was investigated by means of a growth trial at a ... -
Role of jellyfish in the plankton ecosystem revealed using a global ocean biogeochemical model
(Copernicus GmbH, 2021)Jellyfish are increasingly recognised as important components of the marine ecosystem, yet their specific role is poorly defined compared to that of other zooplankton groups. This paper presents the first global ocean ...
