In this study, the optimum dietary lipid level was explained by analyzing the growth performance, antioxidant state, lipid metabolism, and gut microbiota of C. quadricarinatus after an eight-week cultivation trial. Six diets with different soybean oil levels (named L0, L2, L4, L6, L8, and L10) were fed to C. quadricarinatus (\n                    <jats:inline-formula>\n                      <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mn>11.39<\/a:mn>\n                        <a:mo>\u00b1<\/a:mo>\n                        <a:mn>0.28<\/a:mn>\n                        <a:mtext>\u2009<\/a:mtext>\n                        <a:mtext>g<\/a:mtext>\n                      <\/a:math>\n                    <\/jats:inline-formula>\n                    ). The results indicated that the specific growth rate and weight gain of crayfish fed the L4 and L6 diets were significantly higher than those of the other groups (\n                    <jats:inline-formula>\n                      <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.05<\/c:mn>\n                      <\/c:math>\n                    <\/jats:inline-formula>\n                    ). By the analysis of a second-order polynomial regression model according to growth performance (weight gain rate), the optimum lipid level in a practical diet for juvenile C. quadricarinatus was 9.67%. The survival, condition factor, and hepatosomatic index of crayfish were not significantly affected by dietary oil levels (\n                    <jats:inline-formula>\n                      <e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\">\n                        <e:mi>P<\/e:mi>\n                        <e:mo>&gt;<\/e:mo>\n                        <e:mn>0.05<\/e:mn>\n                      <\/e:math>\n                    <\/jats:inline-formula>\n                    ). As the level of dietary lipids increased, the total antioxidant capacity and glutathione peroxidase activity in serum showed a tendency to rise and then fall and the enzyme activity was highest in crayfish fed the L6 diet. Gut lipase and pepsin activities showed the highest value in crayfish fed the L6 diet. There was no significant difference in acetyl-CoA carboxylase and carnitine palmitoyltransferase-1 contents in crayfish among all the groups (\n                    <jats:inline-formula>\n                      <g:math xmlns:g=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\">\n                        <g:mi>P<\/g:mi>\n                        <g:mo>&gt;<\/g:mo>\n                        <g:mn>0.05<\/g:mn>\n                      <\/g:math>\n                    <\/jats:inline-formula>\n                    ). The relative abundance of Proteobacteria in the phylum and Citrobacter in the genus showed a significant decrease in crayfish of the L10 diet, while the relative abundance of Firmicutes in the phylum markedly increased compared to that of the other groups (\n                    <jats:inline-formula>\n                      <i:math xmlns:i=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M5\">\n                        <i:mi>P<\/i:mi>\n                        <i:mo>&lt;<\/i:mo>\n                        <i:mn>0.05<\/i:mn>\n                      <\/i:math>\n                    <\/jats:inline-formula>\n                    ). In summary, the results indicated that the 10.39% (L6 diet) dietary lipid level could induce better growth performance, antioxidant ability, and digestive enzyme activity. Most of the fatty acid composition of muscle is not closely related to the fatty acid composition of the diet. Moreover, the composition and diversity of the gut microbiota of C. quadricarinatus were changed by high dietary lipid levels.\n                  <\/jats:p>","DOI":"10.1155\/2022\/2640479","type":"journal-article","created":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T15:35:22Z","timestamp":1663688122000},"page":"1-16","source":"Crossref","is-referenced-by-count":14,"title":["The Optimum Lipid Level for the Juvenile Redclaw Crayfish Cherax quadricarinatus: Practical Diets with Soybean Oil as the Lipid Source"],"prefix":"10.1155","volume":"2022","author":[{"given":"Chengzhuang","family":"Chen","sequence":"first","affiliation":[{"name":"Key Laboratory of Tropical Hydrobiology and Biotechnology of Hainan Province, Hainan Aquaculture Breeding Engineering Research Center, College of Marine Sciences, Hainan University, Haikou, Hainan 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9985-7634","authenticated-orcid":true,"given":"Chang","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tropical Hydrobiology and Biotechnology of Hainan Province, Hainan Aquaculture Breeding Engineering Research Center, College of Marine Sciences, Hainan University, Haikou, Hainan 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tropical Hydrobiology and Biotechnology of Hainan Province, Hainan Aquaculture Breeding Engineering Research Center, College of Marine Sciences, Hainan University, Haikou, Hainan 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongyi","family":"Jia","sequence":"additional","affiliation":[{"name":"Agriculture Ministry Key Laboratory of Healthy Freshwater Aquaculture, Key Laboratory of Fish Health and Nutrition of Zhejiang Province, Key Laboratory of Freshwater Aquaculture Genetic and Breeding of Zhejiang Province, Zhejiang Institute of Freshwater Fisheries, Huzhou 313001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1849-8703","authenticated-orcid":true,"given":"Zhimin","family":"Gu","sequence":"additional","affiliation":[{"name":"Agriculture Ministry Key Laboratory of Healthy Freshwater Aquaculture, Key Laboratory of Fish Health and Nutrition of Zhejiang Province, Key Laboratory of Freshwater Aquaculture Genetic and Breeding of Zhejiang Province, Zhejiang Institute of Freshwater Fisheries, Huzhou 313001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8495-2241","authenticated-orcid":true,"given":"Erchao","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Tropical Hydrobiology and Biotechnology of Hainan Province, Hainan Aquaculture Breeding Engineering Research Center, College of Marine Sciences, Hainan University, Haikou, Hainan 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/0305-0491(82)90196-1"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aquaculture.2011.01.004"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.aquaculture.2014.09.018"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.aquaculture.2018.07.031"},{"key":"5","article-title":"Effect of dietary lipid\/essential fatty acid level on Pacific whiteleg shrimp, Litopenaeus vannamei (Boone, 1931) reared at three different water salinities\u2013Emphasis on growth, hemolymph indices and body composition","volume":"513, article 734405","author":"R.
