Abstract

Asian redtail catfish (Hemibagrus nemurus) are fish that have high economic value. The Aimed of this study was to know of the effect the use of fermented Pistia stratiotes flour and to know the percentage of best P. stratiotes flour fermentation on the growth of Asian redtail catfish fingerling. The method in this study is a completely randomized design (CRD) with five treatments and three replications, the treatments are P0 (100% soybean flour, 0% fermented P. stratiotes flour), P1 (TK 95%, TKAT 5%), P2 (P2 TK 90%, TKAT 10%), P3 (TK 85%, TKAT 15%), and P4 (TK 80%, TKAT 20%). The fish used were 5.00 ± 1.00 cm long and weighed 1.50 ± 0.50 g, with a stocking density of 20 fish/m3. Fish are kept for 56% with a frequency of feeding three times a day. The results showed that the substitution of fermented P. stratiotes flour was able to effect the growth of Asian redtail catfish. The dosage of fermented P. stratiotes flour as much as 15% gives the best results on the growth of Asian redtail catfish, namely the specific growth rate (SGR), feed efficiency, and survival rate of 3.93%, 46.47% and 96.7%.

发酵层状臭臭鱼粉在亚洲红尾鲶鱼饲料中的应用

亚洲尾鲶(Hemibagrus nemurus)是一种具有很高经济价值的鱼类。本研究的目的是了解使用发酵的层状臭鱼粉对亚洲红尾鲶鱼鱼种生长的影响，并了解最佳层状臭鱼粉发酵的百分比。采用完全随机设计(CRD)， 5个处理，3个重复，分别为P0(100%大豆粉，0%发酵地沟扁豆粉)、P1 (TK 95%， TKAT 5%)、P2 (P2 TK 90%， TKAT 10%)、P3 (TK 85%， TKAT 15%)和P4 (TK 80%， TKAT 20%)处理。鱼长5.00±1.00 cm，体重1.50±0.50 g，放养密度为20尾/m3。养鱼率为56%，饲喂频率为每日3次。结果表明，发酵后的层状霉粉对亚洲红尾鲶鱼的生长有一定的影响。发酵层状霉粉添加量为15%时，对亚洲红尾鲶鱼的生长效果最佳，其特定生长率(SGR)、饲料效率和成活率分别为3.93%、46.47%和96.7%。
