Use of micro-algae concentrates for hatchery culture of sandfish, Holothuria scabra

Improving the fitness of Holothuria arguinensis larvae through different microalgae diets

“…and Thalassiosira weissflogii as single diets, and a combined diet of equal ratio of the three species to fed H. scabra larvae. These studies demonstrated that the single diet of T. weissflogii reported higher larvae survival, percentage of late auricularia with hyaline spheres, number of hyaline spheres with higher diameter and higher proportion of competent doliolaria larvae than the other diets (Duy, Francis, Pirozzi et al., ; Duy, Francis & Southgate, ). In that studies, the authors determined the biochemical composition of the different diets to assess the relationship between this variable and several larvae performance indicators (Duy, Francis, Pirozzi et al., ; Duy, Francis & Southgate, ).…”

In that studies, the authors determined the biochemical composition of the different diets to assess the relationship between this variable and several larvae performance indicators (Duy, Francis, Pirozzi et al., ; Duy, Francis & Southgate, ). The result showed that there was a negative correlation among dietary protein level and key performance indicators, and among total dietary lipids content and larval growth and settlement success (Duy, Francis, Pirozzi et al., ; Duy, Francis & Southgate, ).…”

“…Similar results were obtained on H. scabra larvae′s growth fed with a combination of C. muelleri (40%), I. galbana (40%) and P. salina (20%), and using the single microalgae C. muelleri ; however, higher larvae survival and competent doliolaria larvae were obtained with the single feeding of C. muelleri (Knauer, ). In addition, Duy, Francis, Pirozzi et al., ; Duy, Francis & Southgate, assessed commercial microalgae concentrates of Isochrysis sp ., Pavlova sp . and Thalassiosira weissflogii as single diets, and a combined diet of equal ratio of the three species to fed H. scabra larvae.…”

In addition, they showed that higher EPA:DHA ratio supported significantly better larval growth, greater hyaline spheres in auricularia larvae, higher competence in doliolaria stage and better settlement success (Duy, Francis, Pirozzi et al., ; Duy, Francis & Southgate, ).…”

Selective Feeding and Microalgal Consumption Rates by Crown-Of-Thorns Seastar (Acanthaster cf. solaris) Larvae

“…Likewise, information pertaining to the energetic content and nutritional value of these species is minimal and requires in-depth investigation. This is especially apparent considering the discriminatory feeding nature of CoTS and the previous demonstration of nutritional augmentation of growth and survival in other larval echinoderm species in response to varying phytoplankton feed sources [49]. The highest phytoplankton concentrations in flood plumes of the Great Barrier Reef were dominated by Skeletonema sp.…”
