Research ArticleOpen accessIn the abstractAssessment of Hydroponically Grown Macrophytes for Their Suitability as Fish FeedA. M. Snow, Abdel E. GhalyWater hyacinth, water lettuce and parrot's feather plants were examined for their ability to remove nutrients from aquaculture wastewater at two retention times. During the experiment, the aquatic plants grew rapidly in the hydroponics system and appeared healthy with green color. At hydraulic retention times (HRTs) of 6 and 12 days, the average water hyacinth, water lettuce and parrot's feather … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Assessment of Hydroponically Grown Cereal Crops for the Purification of Aquaculture Wastewater and the Production of Fish FeedA. M. Snow, A. E. Ghaly, A. SnowHydroponically grown wheat, barley and oats were examined for their ability to remove nutrients from aquaculture wastewater. Wheat, barley and oats seeds were germinated in water in a hydroponics system. The seedlings then received wastewater from an aquaculture system stocked with Arctic charr. During the experiment, the crops grew rapidly and fairly uniformly and showed no signs of mineral deficiency … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 9,167 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Nutritive Value of Wastewater Grown Barley and its Utilization in Fish FeedA.M. Snow, A. E. GhalyThe feasibility of using wastewater grown barley plants as a component of fish feed was evaluated. The barley plants were grown in a hydroponics system on wastewater from a recirculating aquaculture facility. The effects of wastewater application rate on plant growth and pollution potential reduction were investigated. At the end of the experiment, the average crop heights and yields were … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,878 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSeasonal Pattern of Varroa Mite Infestation and Its Impact on Honey Production in Apis mellifera Beekeeping in Chitwan, NepalSujan Amgai, Kedar DevkotaHoneybee colony health and productivity are severely affected by infestations of Varroa mites, which have become one of the most significant threats to apiculture due to their role in colony weakening, reduced productivity, and increased colony losses worldwide. The study was conducted in Chitwan district to assess beekeepers’ perceptions on mite infestation in different seasons, its effect on honey production, … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 14 Aug 2026 · 1,234 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of In Vitro Nitrogen Nutrition to Phalaenopsis deliciosa Seedling GrowthChieh Wean Choong, Chin Hao Lim, Zherui Xiong, Siew Mee ChoongIn a continuous effort to conserve Phalaenopsis species, the optimization of a previously designed defined medium was carried out to understand the effect of in vitro nitrogen nutrition on Phalaenopsis deliciosa Rchb.f. In order not to alter the nutrient balance, macronutrient level instead of solely Nitrogen (N) was adjusted. Seedlings were obtained from in vitro germination and randomly inoculated on … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 16 Dec 2015 · 7,824 accessesView PDFCite
