摘要
这项研究的目的是观察红藻鱼(学名Oreochromis niloticus)生长所带来的压力。在本研究中使用的研究设计是一种完全随机的分层设计,由一种具有两种导体的治疗和一种具有两种导体和三层固体tebar 4.6.8条鱼组成。罗非鱼集装箱重量4±0.5 g中所孕育的红色盒子和水量15升容量8升。鱼可以养殖30天。观察到的变量包括鱼的体重、鱼的长度和高度、鱼肉的碳和蛋白质含量。观察到的环境因素包括溶解的氧气(DO)、pH、温度、氨、硝酸盐和硝酸盐。数据分析是通过双向指纹分析进行的。数据分析工作在SPSS版本23中。治疗方法的真正区别是用最小的蚊子测试(BNT)。P < 0.05级评价的真正差异。研究结果显示,单导管作为溶解氧气的来源,tebar的密度增加了一倍。在这项研究中,可以得出结论,河豚的密度仍然可以通过增加溶解的氧气来增加其正常容量的两倍。这项研究是为了检验活空间对大气和密度的影响,它是赤铁矿生长压力的源泉。这项研究中使用的研究发现是一种用两种方法进行的完整的转移设计,考虑到两种焊接和三层袜子的两种焊接和三层袜子的两种焊接。红罗非鱼weighing 4±0。5 g是reared in a box货柜with a capacity of 15升with a 8升的水的体积。鱼撑了30天。观察变化是鱼的长度和高度,carcass的重量和蛋白质组成的肉肉。环境因素观察包括分离氧、pH、温度、氨、硝酸盐和硝酸盐满足。数据分析采用两种变量分析方法进行分析。数据分析采用SPSS版本23个程序进行。treatments之间的重要区别使用了最重要的成分测试(LSD)测试。有争议的差异在P < 0.05的水平上被评估。替代品通过使用一种被稀释的氧气抑制剂和减少卡丝的分量和潜在的鱼肉蛋白质来显示正常电容器的增加。在这项研究中,它可以确定袜子的密度仍然可以增加到与越来越少的氢氧素的附加关系之间的可变电能。
Pertumbuhan Ikan Nila Merah (Oreochromis niloticus) Pada Berbagai Padat Tebar Dan Dengan Penambahan Aerator
Penelitian ini dirancang untuk melihat pengaruh aerasi dan kepadatan tempat hidup sebagai sumber stres terhadap pertumbuhan ikan nila merah (Oreochromis niloticus). Rancangan penelitian yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) faktorial dengan dua perlakuan, terdiri atas perlakuan dilengkapi dengan satu aerator dan perlakuan dolengkapi dengan dua aerator serta tiga tingkatan padat tebar 4,6,8 ekor ikan. Ikan nila merah dengan berat 4±0,5 g dipelihara dalam kontainer boks kapasitas 15 liter dengan volume air 8 liter. Ikan dipelihara selama 30 hari. Variabel yang diamati adalah bobot ikan, Panjang dan tinggi ikan, serta bobot karkas dan kandungan protein daging ikan. Faktor lingkungan yang diamati meliputi Oksigen terlarut (DO), pH, suhu, kandungan ammonia, nitrit dan nitrat. Analisis data dikerjakan menggunakan analisis sidik ragam (ANOVA) dua arah. Analisis data dikerjakan dengan program SPSS versi 23. Perbedaan yang nyata antar perlakuan diuji dengan uji Beda NyataTerkecil (BNT). Beda nyata dievaluasi pada taraf P < 0.05. Hasil penelitian menunjukkan peningkatan padat tebar sampai dengan dua kali lipat kapasitas normal dengan menggunakan satu aerator sebagai sumber oksigen terlarut menghambat pertumbuhan dan menurunkan bobot karkas dan kandungan protein daging ikan. Pada penelitian ini dapat disimpulkan bahwa padat tebar ikan masih bisa ditingkatkan sampai dengan dua kali lipat kapasitas normal dengan penambahan aerator sebagai peningkatan oksigen terlarut.This study was designed to examine the effect of aeration and density of living space as a source of stress on the growth of red tilapia (Oreochromis niloticus).
