A comparative study on growth, protein turnover and energy budget of green and white color morphs of sea cucumber Apostichopus japonicus (Selenka)
A 98 d experiment was conducted to compare the growth performance, protein turnover and energy budget between green and white color morphs of the sea cucumber Apostichopus japonicus. During the experiment, sea cucumbers were fed a single natural diet of Sargassum thunbergii and a premixed artificial...
