Seven dietary treatments were evaluated, including fresh Chlorella sp. at 1 \u00d7 106 cells mL\u22121 (FF1; control) and six mixed dry diets (FF2\u2013FF7) formulated from spirulina powder, commercial shrimp feed, fish meal, and rice bran. Fairy shrimp were cultured for 20 days in a completely randomized design with three replicates per treatment at a stocking density of 30 individuals L\u22121. Growth performance (body length and wet body weight) and survival were assessed across three developmental stages (1\u20135, 6\u201310, and 11\u201320 days post-hatch). Across all developmental stages, FF2 (50% spirulina powder + 50% commercial shrimp feed) consistently supported culture performance comparable to that of the control treatment. During the early developmental stage (1\u20135 days post-hatch), shrimp fed FF2 exhibited growth and survival rates comparable to those of the control group and significantly higher (p &lt; 0.05) than those observed in several other dry diet treatments. During the late developmental stage (11\u201320 days post-hatch), survival of shrimp fed FF2 (62.45 \u00b1 5.28 percent) did not differ significantly from that of the control group (61.85 \u00b1 4.25 percent) but was significantly higher (p &lt; 0.05) than survival in the other dry diet treatments. In addition, shrimp biomass produced with FF2 showed greater protein, lipid, carotenoid, and amino acid contents than shrimp fed fresh Chlorella sp. Protein, lipid, and amino acid contents were determined using standard AOAC methods, and carotenoid content was analyzed by HPLC. These findings suggest that FF2 may serve as a practical algae-independent diet for maintaining growth and survival of S. sirindhornae under controlled hatchery conditions.<\/jats:p>","DOI":"10.3390\/biology15110893","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T08:43:04Z","timestamp":1780648984000},"page":"893","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Dry Feed Formulations for Culturing the Commercial Fairy Shrimp Streptocephalus sirindhornae"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9313-0125","authenticated-orcid":false,"given":"Kosit","family":"Sriphuthorn","sequence":"first","affiliation":[{"name":"Department of Fisheries, Faculty of Natural Resources, Rajamangala University of Technology Isan Sakon Nakhon Campus, Sakon Nakhon 47160, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6205-9510","authenticated-orcid":false,"given":"Prapatsorn","family":"Dabseepai","sequence":"additional","affiliation":[{"name":"Applied Taxonomic Research Center, Department of Biology, Faculty of Science, Khon Kaen University, Khon Kaen 40002, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5864-391X","authenticated-orcid":false,"given":"Naiyana","family":"Senasri","sequence":"additional","affiliation":[{"name":"Department of Fisheries, Faculty of Natural Resources, Rajamangala University of Technology Isan Sakon Nakhon Campus, Sakon Nakhon 47160, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"ref_1","unstructured":"Pennak, R.W.
