This is a very broad category of products and substances that often bring innovative solutions in the field of fertilization and crop protection.The objective of this study is to improve the production of market garden where tomato plants in nurseries from powders of two green algae Ulva lactuca and Ulva intestinalis, harvested as bio-fertilizers in the west coast of Mostaganem province. They have minimal effects on the environment, including soil, subterranean water, River and Estuary ecosystems such as Cheliff River, biodiversity and global warming.The experimental part was carried out following the method of extraction of algae and used as a bio-fertilizer on tomato to its simplicity and accuracy, which is the subject of the study of the germination...

In this study, the effects of temperature stress on occurrence of clinical signs caused A. hydrophila on Capoeta damascina was carried out. For this purpose, 240 C. damascina were captured from Baft's rivers in Kerman province in spring season of 2014 and transported to central laboratory. After adaptation period in first stage, 0.1 ml of 3× 10 8 cfu/ml of A. hydrophila was injected intraperitoneal to each fish. Then, fish were divided into 4 groups (0-10, 10-20, 20-30 and to over 30 o C). After 2 weeks, clinical signs and mortality of each group were recorded. The results revealed that water temperatures can play an important role to pathogenicity of A.hydrophila on C. damascina. Most clinical signs and mortality were observed in 20-30 o C and above groups, although, at 10-20 o C and below 10 o C only 40% and 1% of fish revealed typical clinical signs, respectively.

Feeding animal, fish and poultry with diets supplemented with medicinal plants containing effective compounds and natural antioxidants in thymol demonstrated valuable potential of thymol to enhance the productive and reproductive performances, nutrient bioavailability, immunity and general health of livestock as well as lowering the problems of different animal diseases, side effects of chemical drugs, syntactic materials and cancer. These properties may be attributed to thymol’s capability to work as antispasmodic, antioxidant, antimicrobial, immunomodulatory, anticancer and anti-inflammatory agent by suppressing harmful compounds/free radicals from interacting with cellular biological compounds, ability to alter the gut microbiota, and increasing digestion, absorption and metabolism of nutrients. This review illustrates the multiple beneficial applications and various aspects of thymol including its chemical structure and physical proprieties, metabolism and excretion, mechanisms of action, natural sources and practical applications in animal, fish and poultry nutrition for increasing production, immunity and safeguarding health.

The disease has a wide geographical distribution having been observed in tropical and temperate climates. Up to now, more than forty species mainly of marine origin have been so far affected and this number is likely to rise in future following the introduction of new species and the increase of aquaculture trade. According to OIE all fish mortalities characterized by abnormal swimming behaviours associated with vacuolar lesions in the nervous tissues containing viral particles of the Nodaviridae family should be ascribed to one single disease, officially identified as viral nervous necrosis (VNN) also known as viral encephalopathy and retinopathy (VER). Affected fish may show different clinical symptoms depending on species, age and temperature; furthermore acute and sub-acu...

Some environmental and ecological changes such as red tide and temperature increment could be considered in causing Emerging Disease. Climate warming will be accompanied by increase of average global temperatures. The rate of Global warming will be rise to 1.1°C to 6.4°C so it had been cleared that by climate warming the disease will increase. By 6-fold increase in the temperature, the rate of fish mortality will be rise to 82 to 100 times (4 th IPCC assessment report, 2007). Red tide or planktonic blooming is a phenomenon that phytoplankton accumulate rapidly in the water surface. Some kinds of red tide will be resulting to produce natural toxins, reduce dissolved oxygen and could be greatest risk of red tide that causes mortality in wild aquatic marine and coastal fishes. In Persian Gulf Planktonic blooming started in early October, 2008 from Hormuz and it was observed at the southern coast of Qeshm, Bandar Abba...

(assay I) and immersion bath (assay II) with live theronts of Ichthyophthirius multifillis in Rhamdia quelen and its influence on the hemato-immunological and biochemical parameters. Fish were divided in control (non immunized no challenged); non immunized and challenged with 12,000 theronts/fish; non immunized and challenged with 22,000 theronts/fish; immunized and challenged with 12,000 theronts/fish; immunized and challenged with 22,000 theronts/fish. Six days after challenge, either in the assay I or in the assay II the prevalence of I. multifillis in the gills was higher in non immunized fish (33.33% and 27.77%, respectively). In the assay I showed higher numbers of thrombocytes, leukocytes, lymphocytes, neutrophils and monocytes 20 days after injection and lower numbers after challenge. The immunoglobulin values were higher in fish non immunized. Fish immunized by immersion bath (assay II) showed greater values of catalase (CAT) in the liver (1245.49 U/mgprt) when compared to i.p. (198.79 U/mgprt). The levels of CAT in the liver of fish from the assay II were greater (1.738,47 U/mgprt) 14 days after immunization than that observed 21 days after (1.114,26 U/mgprt). The vaccination by i.p method showed influence on the hematological parameters. On the other hand, the immersion bath vaccination showed greater influence on the catalase activity in the liver. The results showed that new parameters like total protein, immunoglobulin and antioxidant enzymes could be considered in evaluating the host response to infection.

In laboratory dark conditions, newly hatched rainbow trout alevins were exposed to two different doses of UV-B radiation (high dose: HD: 94.83 lW cm À2) and (low dose: LD: 68.75 lW cm À2) for 9 days (time of exposure: 15 min per day), whereas specimens kept in darkness served as a control group. At the end of the experiment, alevins exposed to HD-UVB had the lowest survival rate (43.9 ± 0.9%), whereas fish exposed to LD-UVB showed intermediate values (73.6 ± 0.4%) with regard to the control group (91.2 ± 0.2%). Light microscopic and scanning electron microscopic studies revealed necrosis, sunburned cells, epidermis lifting of the epidermis, reduced number of mucous cells, degeneration of mucous cells and destruction of pavement cell microridges in both UV-B exposed groups. Hemorrhage and inflation in the meningeal layer of the brain were also observed in 17% and 42% of fish exposed to LD-and HD-UVB, respectively.

Five treatments(three replicates/treatment) were employed as follows: treatmentA:fed with commercial diet (control), treatment B: 41 mg/kg AS (astaxanthin as positive control), treatment C: 33 mg/kg RP (Red pepper), treatment D: 44 mg/kg RP, treatments E: 55 mg/kg RP. All treatments were fed in hours 8,12,16, respectively. It should be considered that the feeding rate of biomass weight after each took biometrics. Finally, blood samples were taken from the caudal vein of fish. The results showed a significant difference between treatments in terms of weight and length (p<0.05) and no significant difference (p>0.05) in food intake and growth performance parameters, including Food conversion ration, Specific growth rate, Growth rate, Body weight increase and survival rate but the parameter of Condition factor showed a signific...
