“…Therefore, several kinds of plant-based additives for aquafeed that are used to improve the performance of fish have been studied: plant products such as Astragalus radix and Scutellaria radix (Yin et al 2006); Allium sativum (Sahu et al 2007); mango (Awad & Austin 2010); and Nigella sativa (Awad et al 2013). These plants have been examined in fish to replace antibiotic growth promoters.…”

The effect of dietary Telfairia occidentalis leaf meal on growth, haematological profile, and body composition was investigated in African catfish Clarias gariepinus. Fingerlings of (5.12 ± 0.06 g) average weights were fed diets supplemented with four concentrations (5, 10, 15, and 20 g of T. occidentalis leaf powder/kg feed) for 56 days. Fish fed supplemented diets showed significantly improved growth performance, haematological parameters and feed utilization over the control (0 g T. occidentalis leaf meal/kg feed) treatment. The highest specific growth rate (7.33 ± 2.37% day −1 ) and best food conversion ratio (0.86 ± 0.06) were obtained in the 5 g T. occidentalis leaf meal/kg feed treatment. Protein efficiency ratio was higher in fish fed with T. occidentalis leaf meal and lowest in the control. No differences occurred in fish carcass moisture, protein, or ash content among the treatments (p > .05). The results suggest that dietary supplementation with T. occidentalis leaf powder improved the growth, feed utilization, and survival of C. gariepinus fingerlings. ARTICLE HISTORY

“…Similarly, decreasing in serum lysozyme activity was recorded in dab (Limanda limanda) exposed oil-contaminated sediments (Secombes et al, 1997). On other hand, several studies showed remarkable efficiency by medical plants to enhance immune system in fish and elevate its status to resist infection diseases (Ardo et al, 2008;Awad, 2010;Ndong and Fall, 2011;Awad et al, 2013).…”

“…Using antibiotics and other chemotherapeutics to control diseases may led to the development of strain resistant pathogens, environmental pollution and accumulation of residues in fish (Alexander et al, 2010;Awad et al, 2013). Therefore, there is a great direction toward using medical plants and its active ingredients to enhance the immune and biotransformation systems of farmed fish and elevate their resistance toward infectious diseases (Awad, 2010).…”

Aquatic pollutants are responsible form any alterations in fish health. Our study was designed to examine the efficacy of dietary supplement of black mustard seed, Brassica nigra (30% crude and 1% alcoholic extract) on enhancement the immunity and detoxification response of Nile tilapia, Oreochromis niloticus after exposed to a hydrocarbon pollutant; Benzo-a-Pyrene (BaP). Fish were divided into 3 groups before being fed for 28 days with crude black mustard seeds,1% alcoholic extract and un-supplemented commercial diet as the control. At the end of experiment, fish were exposed to 1 mg LG 1 of BaP for 24 h. Humoral immune parameters (lysozyme activity, antiprotease activity and total protein),ethoxyresorufin-o-deethylase (EROD) and hepatic cytochrome P450 1A1 content (CYP1A1) were investigated. Results recorded high significant difference (p<0.05) of antiprotease and total protein values in group fed with 1% extract followed by crude seeds as compared with control. The highest significant lysozyme activity (p<0.05) was recorded also in group fed with 1% extract as compared with other groups. On the other hand the extract group revealed a significant decrease in EROD (p<0.05) and CYP1A1 content compared to other groups. Which lowering the possible toxic effect of bio-transformed metabolic intermediate compounds.While the EROD activity and CYP1A1 content in group fed with the crude seeds showed increase over the control one. Therefore, the results suggest using of black mustard extract as a dietary supplement to increase the immune function and enhance the detoxification process of pollutants and hence, reduce the harmful effect of aquatic pollutants on Nile tilapia health.

“…Similar elevated lysozyme activity in Oreochromis mossambicus serum was reported to acetone extract (1% w/w) from four medicinal plants (Bermuda grass, Cynodon dactylon; beal Aegle marmelos; winter cherry, Withania somnifera and ginger, Zingiber officinale (Immanuel et al 2009). In addition, Awad et al (2013) notify that they found increased levels of lysozyme in rainbow trout serum which fed with black cumin seed oil and nettle extract. In another study (Baba et al 2016), all concentrations of oat extract-added (Avena sativa) diet fed fish serum lysozyme activity, significantly increased in the oat extract supplemented diet fed groups at all concentrations in C. carpio.…”

The aim of this study was to determine the immunostimulant effects of geophyte plant extract on non-specific defence mechanisms of rainbow trout (Oncorhynchus mykiss). For this purpose, Muscari comosum was collected in Muğla region and extracted in ethanol. Then, The plant extract applied into fish by intraperitonal injection in two different concentrations (0.5mg/ fish and 2.0 mg/fish). The average fish weight was 140 g. Following the injection on the 1st, 7th, 14th, 21st, 28th days the blood and serum samples were collected from fish in each group and examined for various parameters including percentage of hematocrit, the counts of nitroblue tetrazolium (NBT) positive neutrophils, total leukocyte counts, percentage of white blood cells and serum lysozyme activity. The results indicated that the counts of NBT (+) neutrophils, percentage of monocyte and neutophil and total leukocyte counts increased in the group with injected 0.5mg plant extract /fish compared to control group (P<0.05). It has been revealed that this dose of M. comosum can be suggested to use to enhance nonspecific immune system for rainbow trout aquaculture. However, immunostimulant effects of oral administration of this plant extract in rainbow trout are needed to be determine in future studies. Keywords Gökkuşağı Alabalığı (Oncorhynchus mykiss)'nın Spesifik Olmayan Savunma Mekanizması Üzerine Geofit Bitki Ekstraktının İmmunostimulant EtkisiÖz: Bu çalışmada amacımız, gökkuşağı alabalığının spesifik olmayan savunma mekanizması üzerine geofit bitki ektraktının immunostimulant etkisinin belirlenmesidir. Bu amaçla geofit bir bitki olan M. comosum Muğla bölgesinden toplandı ve etanolde ekstrakte edildi. Daha sonra farklı dozlarında (0,5 mg/balık ve 2,0 mg/balık) balıklara intraperitonal olarak uygulandı. Balıklar ortalama 140 g ağırlığa sahipti. Deneme süresince uygulamayı takiben 1, 7, 14, 21, 28. günlerde herbir gruptaki balıktan kan ve serum örnekleri alınarak farklı parametreler (hematokrit yüzdesi, nitroblue tetrazolium (NBT) pozitif nötrofil sayısı, toplam lökosit sayısı, beyaz kan hücrelerinin yüzdesi ve serum lizozim aktivitesi) açısından incelendi. Bu çalışmanın sonucunda NBT pozitif nötrofillerin sayısı, monosit ve nötrofil yüzdeleri ve toplam lökosit sayısı 0,5 mg/balık dozunda injeksiyon yapılan grupta kontrol grubuna kıyasla artış gösterdiği (P<0,05) belirlendi. Bu nedenle gökkuşağı alabalığı yetiştiriciliğinde spesifik olmayan immun sistemi uyarmak için bu dozdaki M. comosum'un kullanılması önerilebilir. Ancak, bitki ekstraktının oral yolla yeme ilave edilerek balıklara uygulanması ile immunostimulant etkisinin belirlenmesi için gelecekte yeni çalışmalara ihtiyaç duyulmaktadır.
