摘要

Gacilia sp.是在国内外市场表现优异的来源。为了满足市场需求,必须采用营养法来满足种子库存。营养是这个过程中的重要因素之一。如果媒体发展得不够,就需要满足需求。本研究旨在了解Walne培养基剂量变化对江豚生长的影响,并寻找最佳剂量作为营养来源。所使用的方法是采用闪酸设计(RAL)的实验实验室方法,使用5个处理、1个对照和3个重复,包括处理A(对照)、B(0.5 ml/L)、C(1 ml/L)和D(2 ml/L),E(4 ml/L)以及F(8 ml/L)。观测到的参数包括大爆炸、金枪鱼、金枪鱼长度、绝对大生长、比生长率和中等水质。使用单向方差分析分析分析的数据继续进行Tukey和Games-Howell检验。结果表明,平均体重、金枪鱼数量和金枪鱼长度之间存在显著差异(p<0.05)。处理E(4ml/L)的平均绝对体重增加为0.07±0.01 g/天,处理E(4 ml/L)的最高比生长率为2.24%/天。人们期望营养物质发挥最佳作用。pH(4-7,92)、盐度(23-32 ppt)和温度(27-31 oC)监测结果。4ml/L的剂量是最佳浓度,因为在该剂量下,Gracilia sp.受到显著影响。[UNK][UNK][UNK][UNK]江豚是琼脂的来源,在国内外市场上都很畅销。为了满足市场需求,必须满足种子库存,其中一种是使用营养方法。营养素是该方法过程中的重要因素之一。如果培养基不够,就需要施肥。本研究旨在确定Walne培养基剂量变化对江豚生长的影响,并了解作为营养来源的最佳剂量。所使用的方法是完全随机设计(CRD)的实验室实验方法,使用5个处理、1个对照和3个重复,包括处理a(对照)、B(0.5毫升/升)、C(1毫升/升,D(2毫升/升、E(4毫升/升和F(8毫升/升。观察到的参数包括外植体重量、芽数、芽长、绝对重量生长、比生长速率和培养基的水质。数据采用单因素方差分析,然后进行Tukey和Games-Howell检验。结果表明,在平均重量、芽数和芽长方面存在显著差异(p<0.05)。平均绝对体重增长最高的是处理E(4ml/L),为0.07±0.01g/天,最高的比生长率是处理E的2.24%/天。人们怀疑营养物质发挥最佳作用。在pH(4–7.92)、盐度(23–32 ppt)和温度(27–31 oC)下观察到了结果。4ml/L的剂量是最佳浓度,因为在该剂量下Gracilia sp.具有显著的效果。

Pertumbuhan Rumput Laut Gracilaria sp. terhadap Variasi Dosis Media Walne
Gacilaria sp. merupakan sumber agar yang sangat laku di pasaran baik dalam negeri maupun luar negeri. Untuk memenuhi permintaan pasar maka stok bibit harus terpenuhi salah satunya dengan menggunakan metode vegetatif. Nutrien merupakan salah satu faktor penting dalam proses metode ini. Jika media tumbuh tidak mencukupi kebutuhan perlu dilakukan pemupukan. Penelitian ini bertujuan untuk mengetahui pengaruh variasi dosis media Walne pada pertumbuhan Gracilaria sp. dan mengetahui dosis optimal sebagai sumber nutrien. Metode yang digunakan adalah metode eksperimental laboratoris dengan Rancangan Acak Lengkap (RAL) menggunakan 5 perlakuan 1 kontrol dan 3 ulangan, antara lain perlakuan A (kontrol), B (0,5 ml/L), C (1 ml/L), D (2 ml/L), E (4 ml/L) dan F (8 ml/L).

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
