We aimed to evaluate the effect of poultry liver protein hydrolysate (PLPH) as feed additive on the productive performance of Nile tilapia reared in a water recirculation system and investigate stress responses and redox status after an air exposure challenge. Nile tilapia juveniles were distributed in 24 aquariums and fed plant-based diets supplem...

We aimed to evaluate the effects of ginger, starch, and it’s interaction on nutrient utilisation efficiency and on productive performance of Nile tilapia. Fish were fed diets containing three levels of corn starch inclusion (300, 400 and 500 g/kg) and four levels of ginger oil (0, 0.57, 1.14 and 2.27 ml/kg). Fish fed with 0.57 ml/kg of ginger oil p...

ABSTRACT We aimed to evaluate the effects of Curcuma longa as growth promoter, skin pigmentation enhancer, and stress reducer in diets of Trichogaster labiosa after transport. We used five diets containing 0.0, 1.0, 5.0, 10.0, and 25.0 g kg−1 of turmeric rhizome powder. We observed quadratic effects of turmeric supplementation for feed intake, weig...

The aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.83 ± 0.04 g) were fed, for 60 days, with six diets containing 0.0, 20.0, 40.0, 60.0, 80.0, and 100.0 g turmeric kg(-1) feed. There was an increasing linear effect of turmeric on the thickness of the musc...

The physiological state of fish before transportation is an important aspect to be observed when reduction in losses due to mortality is aimed. Various preparative procedures for transport are reported, but little is known about the use of additives in fish diet. In this study, we aimed to evaluate the effect of dietary turmeric (Curcuma longa) sup...

With this study, we aimed to assess the safety of using Curcuma longa in fish feed. Juvenile Astyanax aff. bimaculatus (0.83 ± 0.04 g) were kept in 24 80-L aquaria, at a density of 0.5 fish L−1 for 60 days. Six diets supplemented with 0.0, 20.0, 40.0, 60.0, 80.0 and 100.0 g kg−1 were evaluated. Histopathological analysis of the gills showed that th...

This study aimed to evaluate the effect of oregano oil on the intestinal and liver morphometry of yellow tail tetra, Astyanax altiparanae. Fish (1.46 ± 0.09 g) were kept in a 60-L aquaria, at a stocking density of 0.5 fi sh L-1. Six diets containing varying amounts of oregano oil were evaluated (0.0; 0.5; 1.0; 1.5; 2.0 and 2.5 g of oregano oil kg-1...
Article
This study aimed to evaluate the potential of oregano oil as a growth promoter for the yellowtail tetra, Astyanax altiparanae. The fish (1.46 ± 0.09 g) were distributed into twenty-four 60-L aquaria at a stocking density of 0.5 fish/L. Six isonitrogenous (350 g crude protein/kg) and isocaloric (4272 kcal gross energy/kg) diets containing 0.0, 0.5,...

... Dietary GRJE supplementation significantly improved rockfish growth (final weight, weight gain, and SGR) and feed utilization (FE and PER), even at the lowest dose (0.25% GRJE). Numerous studies have shown that dietary supplementation with various types and concentrations of ginger significantly affects growth and feed utilization in fish [1,20,21,[34][35][36]. Similar to our study, Naliato et al. [19] showed that growth performance parameters of Oreochromis niloticus including final body weight, WG, SGR, feed intake and feed conversion ratio, and PER were responsive to the increase on dietary ginger powder supplementation, showing a dose-dependent response and a linear correlation. ...
... reticulata) fed with diets added turmeric powder (0.09 %). However, Nascimento et al., (2019) indicated that supplementing to diets of turmeric powder (0-2.5 %) no improved the orange pattern of skin pigmentation of Trichogaster labiosa orange thick-lipped gourami. Similarly, in the present study, the pigmentation increased statistically by increasing of turmeric powder ratio in diets. ...
... Eugenol (4-allyl-2-methoxyphenyl) from Eugenia caryoplyllata, Pimenta dioica, Pimentara cemosa, Szygium aromaticum, and Cinnamomum zeylanicum exhibits biological activities, such as antimicrobial, antioxidant, antifungal, anti-inflammatory and anti-carcinogenic [29,30]. Furthermore, curcumin, cinnamaldehyde and eugenol are reported as safe to use in aquaculture practices [31][32][33]. Stigmasterol from the root of Dipsacus asper has been reported to possess antifungal activity [34]. Bioactive compounds morin possess anticancer, allelopathic, antifungal and antioxidant activities [35]. ...
... Selama proses transportasi benih vaname, terjadi penurunan kualitas air akibat akumulasi gas beracun seperti amonia, nitrit, karbon dioksida dan konsentrasi oksigen yang semakin menurun, dapat mempengaruhi kesehatan (stres) benih sampai lokasi tambak pembesaran. Benih yang stres ditunjukkan dengan kadar glukosa darah yang meningkat (Ferreira et al., 2017). Hasil pengukuran kadar glukosa darah pada akhir transportasi dapat dilihat pada Tabel 2. Tabel 2 menunjukkan bahwa sumber oksigen yang menggunakan nannobubble dan durasi transportasi tidak berpengaruh nyata terhadap kadar glukosa darah (P>0,05), demikian juga kombinasi perlakuan sumber oksigen dan durasi transportasi tidak berbeda nyata terhadap kadar glukosa darah (P>0,05). ...
... Fragments of the organs (intestine, liver and kidney) were fixed in Karnovsky fixative solution for 24 h at room temperature and transferred to 70% ethanol. 34 The organs were dehydrated in an ascending series of ethanol and embedded in glycol methacrylate (Historesin, Leica, Germany). Sections of 3 μm thickness were used, with a range of 30 μm. ...
... Our result obtained with laurel essential oil supplementation in terms of intestinal villus height is harmonious with that reported by Yusuf et al. (2017). Ferreira et al. (2016) found that the increased villus height and width in fish fed with oregano essential oil may be due to the antimicrobial property of this product. According to Snuossi et al. (2016), laurel essential oils have antimicrobial activity. ...
... Furthermore, carvacrol and thymol, the principal compounds in OO, have preeminent antioxidant properties and are effective in retarding the process of lipid peroxidation in fatty food and scavenging free radicals (Quiroga et al., 2013;Rodriguez-Garcia et al., 2016;Asensio et al., 2017). However, despite the fact that previous studies have shown that OO also has growth-promoting effects in fish and the dose is a very important factor (Ferreira et al., 2014), research on OO in fish is still relatively limited and incomplete. ...
