An outdoor pot experiment was carried out in sand culture to investigate the response of spinach (Spinacia oleracea ) cv. “Matador” grown at high salinity to supplementary phosphorus and potassium. Plants were tested during a period from germination to vegetative growth stage. Treatments initiated for seedling and more matured vegetative growth stages were (1) complete nutrient solution alone (...

abstarct at the present study effects of salinity were studied on growth and feeding performance, survival rate and blood biochemical parameters of pre on-growing rainbow trout (oncorhynchus mykiss) with initial weight 93.22±4.11 g for 60 days. after adaptation for 10 days to water salinity, 450 fish were distributed in 5 treatments and 3 replicates according to completely randomized design. be...

This study examined the extent of phenotypic plasticity for salinity tolerance and genetic variation in plasticity in the invasive copepod Eurytemora affinis. Euryemora affinis is a species complex inhabiting brackish to hypersaline environments but has invaded freshwater lakes and reservoirs within the past century. Reaction norm experiments were performed on a relatively euryhaline population...

The subarctic front is a thermohaline structure across the North Pacific, separating colder, fresher water to the north from warmer, saltier water to the south. Levitus's [1982] data and 72 conductivity-temperature-depth/salinity-temperature-depth sections are used to show the spatial and seasonal variations of the climatological frontal zone and the characteristics of the frontal structure in ...

The processing of intestinal fluid, in addition to a high drinking rate, is essential for osmoregulation in marine fish. This study analyzed the long-term response of the sea bream (Sparus aurata L.) to relevant changes of external salinity (12, 35 and 55 p.p.t.), focusing on the anterior intestine and in the less-often studied rectum. Intestinal water absorption, epithelial HCO(3)(-) secretion...

BENFER, N.P., KING, B.A. and LEMCKERT, C.J., 2007. Salinity observations in a subtropical estuarine system on the Gold Coast, Australia. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 646 – 651. Gold Coast, Australia, ISSN 0749.0208 Saltwater Creek and Coombabah Creek are branches of the Coomera River estuary situated within the subtropical Gold Coa...

plants for optimal growth requires absorb water and nutrients absorption from the soil. magnetic water downward movement of minerals and makes it easy for plants to absorb nutrients and water. this study was designed to investigate the effect of magnetic salt water on some quantity and quality characteristics of artichoke leaves. the experiment was factorial based on completely randomized desig...

10 This paper presents an investigation of the impacts of a Severn Barrage on the hydro-environment of 11 the Bristol Channel and Severn Estuary using the Environmental Fluid Dynamics Code (EFDC) model 12 with a recently developed Barrage module (EFDC_B). Details are given of a barrage module being 13 implemented into the EFDC model to represent the various hydraulic structures, such as turbine...

Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...
