Abstract

Rainbow kurumoi (Melanotaenia parva) merupakan salah satu ikan endemik Indonesia yang berasal dari Danau Kurumoi, Papua. Ikan ini merupakan salah satu komoditas potensial untuk perdagangan ikan hias. Akan tetapi, pemenuhan permintaan ikan rainbow masih mengandalkan hasil tangkapan alam. Rekayasa lingkungan diperlukan untuk meningkatkan produksi ikan rainbow ini. Penelitian ini bertujuan untuk mengetahui warna wadah yang sesuai untuk optimalisasi pemeliharaan larva ikan rainbow kurumoi. Perlakuan dalam penelitian ini adalah: A) warna wadah merah; B) warna wadah biru; dan C) warna wadah hijau. Larva dipelihara dalam wadah volume 4 L dengan kepadatan 20 ekor/L selama 28 hari. Pakan yang diberikan berupa infusoria, Rotifer, Artemia, dan Moina secara bertahap dengan metode ad libitum. Hasil penelitian menunjukkan bahwa larva yang diberikan perlakuan beda warna wadah tidak berbeda nyata (P>0,05) terhadap pertumbuhan dan sintasan. Perlakuan A (warna wadah merah) menunjukkan laju pertumbuhan spesifik panjang tertinggi yaitu sebesar 2,2 ± 0,1%/hari; dilanjutkan perlakuan B (2,1 ± 0,7%/hari); dan terakhir perlakun C (1,8 ± 0,7%/hari). Untuk laju pertumbuhan spesifik berat pada perlakuan A sebesar 6,7 ± 1,2%/hari; diikuti perlakuan C (6,4 ± 0,3%/hari) dan perlakuan B (5,5 ± 1,6%/hari).

来自巴布亚库鲁莫伊湖的印尼海鱼之一。这种鱼是花鱼贸易的潜在商品之一。然而，彩虹鱼的满足要求仍然依赖于自然捕捞。提高这条彩虹鱼的产量需要环境工程。本研究旨在确定彩虹库鲁莫伊鱼幼虫保育的容器的颜色。在这项研究中，治疗方法是:A)红色容器的颜色;B)容器的颜色为蓝色;C)容器的颜色为绿色。养幼虫的容器体积为4升，密度为20天/L。以inforia、Rotifer、青蒿素和Moina为基础的喂养逐渐采用了公元libitum方法。研究结果表明，对不同颜色容器的治疗并没有明显(P> 0.05)对生长和牙龈的影响。A待遇(容器红色)明确显示增长率最高的长度即高达2.2±0.1% /天;继续B(2.1±待遇0.7% /天);最后,perlakun C(1.8±0.7% /天)。为了具体的重量A待遇增长率高达6.7±49岁/天;遵循C(6.4待遇±0.3% /天)和B(5.5±待遇1.6% -天)。彩虹kurumoi (Melanotaenia parva)是来自印度尼西亚巴布亚鲁莫伊湖(kurumoi Lake)的一种特有的鱼。鱼被认为是鱼市场的潜在商品之一。等等，供应彩虹鱼的要求仍然是疯狂的捕获。环境控制需要改进彩虹鱼的生产。这项研究的目标是评估坦克在鲁莫伊彩虹拉维的生长颜色上的影响。这次研究的题目是:A)红色;B)蓝;绿色坦克。拉vae在4个L的坦克里，有20个舵的密度。拉vae是美联储的，在stages，以infuoria, Rotifer，青蒿素，和有拔利比乌的方法的Moina。results那里的《最高红坦克(A)有非常具体的增长速率长度正好(2.0±2。1% / day)跟着由蓝(B) (2 - day 1±0。7%)和格林(C)(1)。8±0。7% - day)坦克。《最高红坦克(A)有非常具体重量增长速率(6 - 9±1。2% - day)跟着由绿(C)(6)。4±0。3% / day)和《lowest是蓝色(B)(5。5±1。6% - day)坦克。幼虫生活在红色的坦克里，比其他两种坦克更明亮。在孵化后的27天内完成。这个研究的颜色坦克对彩虹库鲁莫伊·拉维的成长和生存没有任何影响。
