“…For example, Chaetoceros calcitrans is effective for rearing larval Bohadschia marmorata [21], H. spinifera [22], and Parastichopus californicus [19], and dry yeast S. cerevisiae or sea yeast R. benthica can be used as stable food for A. japonicus larvae [20,31,33]. However, multispecies diets are usually used to rear holothurian larvae [5,13,17,20,29,30,50]. Combined diets are generally more nutritionally 6 Aquaculture Nutrition balanced and efficient than single diets.…”

“…Identifying suitable diets is the most important step for sea cucumber hatchery. Diets should be high-quality and relatively inexpensive and not be difficult or sophisticated to culture [17][18][19][20]. Traditional diets for rearing sea cucumber larvae have mainly used live microalgae.…”

“…The microalga Chaetoceros muelleri can tolerate a high temperature, salinity, photoperiod, and light intensity range and is characterized by fast growth and easy maintenance [24,[26][27][28]. Because this species is highly nutritious, it is often used as a food in aquaculture, and it is widely used in sea cucumber hatcheries for species such as A. japonicus, H. scabra, Australostichopus mollis, and Stichopus horrens [13,20,23,24,[29][30][31]. The alga C. muelleri could represent an integral component of the diet for rearing H. leucospilota larvae [5,15].…”

“…paste are effective for growing late auricularia larvae of H. scabra [ 12 ], commercially available microalgae concentrates could also be used to replace live microalgae for this species [ 18 , 34 , 35 ] and for A. japonicas [ 31 ]. Baker's (dry) yeast Saccharomyces cerevisiae and red yeast Rhodotorula benthica , both rich in protein and vitamins, are also acceptable phytoplankton substitutes for A. japonicus larvae [ 20 , 31 – 33 ] .…”

Because most tropical sea cucumbers have been overexploited around the world, the sea cucumber Holothuria leucospilota has become increasingly commercially important in recent years. Restocking and aquaculture of H. leucospilota using hatchery-produced seeds could both enhance declining wild populations and provide sufficient beche-de-mer product to satisfy increasing market demand. Identifying an appropriate diet is important for successful hatchery culture of the H. leucospilota. In this study, we trialed different ratios of microalgae Chaetoceros muelleri ( 2.00 – 2.50 × 10 6 cells/mL) and yeast (Saccharomyces cerevisiae, ~ 2.00 × 10 6 cells/mL) in diets for H. leucospilota larvae (6 d after fertilization, referred to as “day 0”) at proportions 4 : 0, 3 : 1, 2 : 2, 1 : 3, and 0 : 4 by volume, in 5 treatments (A, B, C, D, and E, respectively). Larval survival rates in these treatments decreased over time, with the survival highest in treatment B ( 59.24 ± 2.49 %) on day 15 (double that of the lowest rate in treatment E ( 28.47 ± 4.23 %)). For any sampling event, larval body length in treatment A was always the lowest after day 3, and that for treatment B was always the highest, except on day 15. The maximum percentage of doliolaria larvae occurred in treatment B (23.33%) on day 15, followed by treatments C, D, and E (20.00%, 10.00%, and 6.67%, respectively). No doliolaria larvae occurred in treatment A, and pentactula larvae occurred only in treatment B (3.33%). On day 15 in all treatments, late auricularia larvae had hyaline spheres, but these were not prominent in treatment A. Densities of juveniles attaching to settlement plates varied with treatments, and the values were very low for the larvae only fed microalgae (A, 2.39 ± 1.95 ind per plate) or yeast (E, 2.13 ± 1.05 ind per plate)—only ~5% of the maximum number settling in treatment B ( 45.56 ± 7.24 ind per plate). Increased larval growth, survival and development, and juvenile attachment indicates that diets combining microalgae and yeast are more nutritionally balanced than single diets for hatchery of H. leucospilota. A combined diet of C. muelleri and S. cerevisiae at a 3 : 1 ratio is optimum for the larvae. Based on our results, we propose a larval rearing protocol to facilitate mass production of H. leucospilota.

Now decrease press of the fishery on natural populations of hydrobionts and restoration of their number due to artificial reproduction is actual. At artificial cultivation important properly to choose the right feed. To develop the feeding technology, work was carried out with larvae and juveniles of sea cucumber and gray sea urchin in the conditions of the mini-plant of the Scientific and Production Department of Mariculture of the Far Eastern State Technical Fisheries University located in Severnaya Bay (Slavyansky Gulf, the Sea of Japan) and Troitsa Bay (Vladimir Gulf, the Sea of Japan). Experimental studies have shown the possibility of using the sea yeast Rhodotorula benthica as either the main feed or as a feed additive. Practical recommendations have been developed for the use of Rhodotorula benthica yeast as a substitute feed base for growing larvae and juveniles of Japanese sea cucumber and gray sea urchin. The results of the work will serve as a basis for the development of biotechnology for feeding at echinoderm breeding farms and will be useful to the organizations, whose duties include rational and competent progress of marine economic territories.
