浮萍（浮萍科）是一种很有潜力的替代鱼粉的水产饲料原料。在室外水池中规范了浮萍的养殖技术，并将其应用于池塘中。在1.2 × 0.35 × 0.3m的水槽中进行了三次连续实验。试验1采用四种不同的有机肥。在粪肥1（有机肥，OM）和粪肥3（2x OM），牛粪，家禽粪便，芥末油饼（1：1：1）使用;在粪肥2（无机肥，IF），尿素，钾肥，三重过磷酸钙使用;粪肥4（2x OM+IF）是粪肥2和粪肥3的组合。试验2采用有机肥1（OM）和有机肥2（IF），有机肥3（OM+IF）为两种有机肥的组合。试验3选用OM和IF。池塘（20 × 10 × 0.5m）施用有机肥。在施用粪肥5天后播种新鲜浮萍。在试验1和3中，OM处理的总产量显著高于其他处理（P < 0.05）。在试验2中，OM和IF的产量差异不显著（P > 0.05）。池塘中浮萍的相对生长率（RGR）为0.422 ~ 0.073 g/g/d，总产量为702.5 Kg/ha/月（干重）。OM培养的浮萍蛋白质、脂肪和灰分含量均高于IF培养的浮萍。浮萍是必需氨基酸（39.20%）、非必需氨基酸（53.64%）和非蛋白质氨基酸（7.13%）的丰富来源。必需氨基酸中亮氨酸、异亮氨酸、缬氨酸占48.67%。谷氨酸占非必需氨基酸总量的25.87%。在浮萍中发现了瓜氨酸、羟脯氨酸、牛磺酸等。脂肪酸组成以PUFA为主，占总脂肪酸的60-63%，主要是α-亚麻酸（LNA，18：3 n-3），约占41 - 47%，亚油酸（LA，18：2n-6）占17- 18%。对浮萍的营养价值及其在池塘条件下的生产潜力进行了评价。因此，浮萍生物质可用于替代目前水产养殖中使用的商业鱼粉。
The surface floating duckweed Lemna minor (Lemnaceae) is a potential ingredient to replace the application of fish-meal in the aqua-feed. The culture technique of the duckweed was standardized in outdoor tanks and then applied in the pond. Three consecutive experiments were conducted in tanks (1.2 × 0.35 × 0.3 m). In experiment 1, four different manures were used. In manure 1 (organic manure, OM) and manure 3 (2x OM), cattle manure, poultry droppings, and mustard oil cake (1:1:1) were used; in manure 2 (inorganic fertilizer, IF), urea, potash, triple superphosphate were used; manure 4 (2x OM+IF) was a combination of manure 2 and manure 3. In experiment 2, manure 1 (OM) and manure 2 (IF) were used, and manure 3 (OM+IF) was a combination of both manures. In experiment 3, OM and IF were selected. In pond (20 × 10 × 0.5 m), OM was applied. Fresh duckweed was seeded after 5 days of manure application. In experiments 1 and 3, total production was significantly (P < 0.05) higher in OM compared to other treatments. In experiment 2, there was no significant (P > 0.05) difference in production between OM and IF. In pond, relative growth rate (RGR) of duckweed ranged from 0.422 to 0.073 g/g/day and total production was 702.5 Kg/ha/month (dry weight). Protein, lipid, and ash contents were higher in duckweed cultured in OM compared to IF. The duckweed was a rich source of essential (39.20%), non-essential (53.64%), and non-proteinogenic (7.13%) amino acids. Among essential amino acids, leucine, isoleucine, and valine constituted 48.67%. Glutamic acid was 25.87% of total non-essential amino acids. Citrulline, hydroxiproline, taurine, etc. were found in the duckweed. The fatty acid composition was dominated by PUFA, 60–63% of total fatty acids, largely α-linolenic acid (LNA, 18:3n-3) at around 41 to 47% and linoleic acid (LA, 18:2n-6) at 17–18%. The nutritional value of duckweeds and their production potential in the pond conditions were evaluated. Duckweed biomass may thus be used to replace commercial fish-meal that is currently used in aquaculture.
