Guava Psidium guajava L (Pg) and bhumi amla Phyllanthus amarus Schum. et Thonn (Pa) are well-known plants in traditional medicine. However, the capacity of these for improving immune system aquatic species has received less attention so far. This study aimed to investigate effects single supply or mixture Pg Pa extracts on responses, disease resistance liver proteome profiles striped catfish Pangasianodon hypophthalmus. Fish were fed diets including basal diet 0% one three doses each plant...
This study aimed to screen the in vitro antioxidant and antimicrobial activities of ethanolic extracts from 20 plants three herbal commercial products empirically used for aquaculture improvement Vietnam. The results 2,2-diphenyl-1-pycrylhydrazyl (DPPH) radical scavenging assays showed that Phyllanthus amarus extract was strongest antioxidant, followed by four subsequent order: Piper betle > Psidium guajava Euphorbia hirta Mimosa pudica. These five plant were very active a DPPH assay with...
This study investigated the effect of dietary arachidonic acid (ARA, 20:4n-6) on final maturation, spawning performance and composition gonad black sea urchin (Diadema setosum). Four different ARA levels 0.3 g/kg (Control diet), 1.4 (ARA 1.4), 2.5 2.5) 3.7 3.7) were prepared tested in this feeding trial for 90 days. The result showed that growth terms weight was not relatively affected by ARA. Gonadosomatic Index (GSI) animals gradually increased all diets throughout trial. highest GSI level...
Hydrogen peroxidase-inactivated vaccines have recently developed in controlling infectious diseases aquaculture. The present study aimed to compare the efficacy of hydrogen Streptococcus agalactiae vaccine via different delivery routes (injection, immersion, and oral administration) red tilapia (Oreochromis sp.) without using adjuvant. Fish were randomly divided into 4 groups including G1: Control treatment (without vaccine), G2: vaccine-based diet (oral administration), G3: vaccinated by...
This study is aimed to evaluate the effect of levamisole-enrich diets on innate immune response striped catfish (Pangasianodon hypophthalmus). Different concentrations levamisole (0, 50, 150, 300 and 450 mg/kg) were incorporated with fish feed for a period 4 weeks. Experimental challenged intra-peritoneally Edwardsiella ictaluri in 4th week after feeding levamisole. Hematological immunological parameters determined 2 4. The results experiment reveased that total leukocyte count, monocytes...
Edwardsiella (E.) ictaluri is a major bacterial pathogen that affects commercially farmed striped catfish (Pangasius hypothalamus) in Vietnam. In previous study, 19 strains of E. collected from were biochemically identified with an API-20E system. Here, the same used to assess ability matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF MS; applied using MALDI Biotyper) conduct rapid, easy and accurate identification ictaluri. MALDI-TOF MS could directly...
Reproductive characteristics of black sea urchin Diadema setosum was studied during the period April 2016 to 2017. A total 632 specimens were collected from intertidal reef at Hon Son, Kien Giang province, Viet Nam. Monthly data collection showed that reproductive cycle seasonal dependence. The highest gonadosomatic index (GSI) found in June (16.10±7.70), but no differ significantly with those GSI occurring July. lowest September December and remain low until March next year. suggested...
This study was conducted to evaluate the effects of herbal extracts on quality striped catfish (Pangasianodon hypophthalmus) fillets throughout storage period. Quality changes during ice were studied after dip treatments in aqueous solutions ethanolic extract Phyllanthus amarus (0.02% and 0.04%, w/v) or Euphorbia hirta (0.06% 0.02%, w/v). The control (dipped tap water) treated fish samples analyzed periodically for total viable counts (TVC), peroxide value, physicochemical parameters (pH,...
Psidium guajava and Phyllanthus amarus are well-known as herbs that have been widely used in Vietnamese traditional medicines. However, studies on the effects of these plants improving immune system striped catfish (Pangasianodon hypophthalmus) received less attention. Therefore, this study aimed to investigate effect ethanolic leave extracts from P. guajava, amarus, their mixtures (1: 1, v/v) leukocytes (P. hypophthalmus). Leukocytes (5×106 cells/mL) collected peripheral blood head kidney...
This study was conducted to determine theappropriate feed for maturation culture and spawning induction method on black sea urchin Diadema setosum. Two experiments were conducted. In the first experiment, urchins fed with three different diets including (1) Seaweed Gracilaria sp., 2) pellet feed, 3) combination of weed feed. For second four inductions injection 1.0 mL KCl (0.5M), temperature shock, UV shock H2O2 methods employed induce urchin. The result showed that average survival rate...
This study was conducted to determine the optimum microalgal species and rearing density for black sea urchin’s larvae (Diadema setosum). In first experiment, (2.0 larvae/mL) were fed with four different mixtures of algae [Nannochloropsis oculata Chaetoceros gracillis (N+C); N. Thalassiosira sp. (N+T); C. (T+C); oculata, sp., (N+T+C)] 25 days. The results showed that highest survival rate (60±1.5%) found those mixture N+T+C. Similarly, growth in total body length (TBL), mid-body (MBL) width...
