the influence of different initial inoculum densities of the root-knot nematode meloidogyne javanica on the growth of sage (salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. with the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...

Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...

Two hunared day old broiler chicks were alloted to five treatment groups evaluate the effect of whole soyabean and fish meal supplementation on productivity experimental birds. Feed consump­tion weight gains similar diets 1 -and 3, while feed efficiency protein ratio better (P<0.05) cooked diet 3 as compared groundnut cake based (control) ration. Fish also unproved performance. The raw gave ...

In this study were investigated the effects of Rosehip (Rosa canina L.) oil added to juvenile rainbow trout (Oncorhynchus mykiss diets in different proportions on growth performance, feed efficiency and survival rate fish. For purpose, 4 concentrations (0, 2, 6 ml / kg) was with an initial average weight 1.7 ± 2.8 g, for 90 days (pH 7.15-8.33, temperature 12,3-15.9 °C dissolved oxygen range 6.8...

Two feeding trials were carried out to evaluate the efficiency of probiotics and maslinic acid, on growth and survival of juvenile dentex; liver proteolytic activities were also investigated in the second trial. For experiment 1, triplicate groups were fed six diets with two probiotics (Bacillus toyoi, T, and B. cereus, E) at increasing levels (0.5, 1 and 2 g kg diet) and a control diet. Growth...

the spatial and temporal distribution of heavy metals in water, sediment and fish (dry weight basis) of buriganga river, bangladesh were determined by atomic absorption spectrophotometer. in water concentration of pb, cd, ni, cu and cr varied seasonally and spatially from 58.17 to 72.45î¼g/l, 7.08 to 12.33î¼g/l, 7.15 to 10.32î¼g/l, 107.38 to 201.29î¼g/l and 489.27 to 645.26î¼g/l, respectively. ...

We conducted a 84-day nutritional feeding experiment with dried whole cells of DHA-rich marine microalga Schizochytrium sp. (Sc) to determine the optimum level of fish-oil substitution (partial or complete) for maximum growth of Nile tilapia. When we fully replaced fish oil with Schizochytrium (Sc100 diet), we found significantly higher weight gain and protein efficiency ratio (PER), and lower ...

Eleven diets (D1-D11), designated as treatments (T1-T11), supplemented with different levels of inorganic phosphorus (P) (Ca2PO4) were fed to Heterobranchus bidorsalis (10.8 ±0.02 g) to determine the optimum P requirement. D1 D11 contained total P of 10.2, 10.4, 11.0, 11.9, 12.3, 12.6, 13.4, 13.9, 14.2 14.7 and 15.4 g kg respectively. After 84 days of feeding trial, there was increase in fish g...
