The aim of this work was to investigate the effects of daily prey concentration during the first 15 days of active feeding of Hoplias lacerdae larvae, and the juvenile size on the feed training. In the first phase, the larvae received five Artemia nauplii concentrations (P). In the second phase, the juveniles from each treatment were trained to accept formulated diet. Superior growth was relate...
The antimicrobial activity of the Epilobium angustifolium, E. hirsutum, E. palustre, E. tetragonum and E. rosmarinifolium ethanolic extracts was studied in vitro on Gram-positive and Gram-negative bacteria, yeasts and fungi. The cytotoxicity of the extracts was also evaluated using the Artemia salina test. All the extracts showed antimicrobial activity in a range of concentrations between 10 an...
Nowadays, nanoparticles (NPs) have the great potential application in different industries. Among all NPs, titanium dioxide NPs is the biggest ecotoxicological and ecophysiology concerns due to the increase of anthropogenic input into the aquatic ecosystems. In this study, the effects of titanium dioxide NPs enriched yeast on the growth, survival; digestive enzymes activity and lipid metabolism...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Maculalactone A (1) constitutes a promising antifouling agent, inhibiting the formation of biofilms in marine and freshwater systems. In this study, we developed a new route, based on a late-stage formation of the butenolide core, leading to the total synthesis of maculalactone A (three steps, overall yield of 45%) and delivering material on a gram scale. In addition, analogues of the title com...
این پژوهش باهدف بررسی تغذیه آرتمیای فرانسیسکانا (Artemia fransiscana) غنیشده با روغن کبد ماهی کاد و ویتامین C بر روی میزان رشد، بازماندگی و مقاومت لاروهای ماهی مرکب ببری در برابر تنش شوری و دمایی، در ایستگاه نرمتنان خلیجفارس بندرلنگه انجام گرفت. لاروهای ماهی مرکب ببری، بیستوپنج روز پس از هچ با میانگین طول 15/0 ± 97/15 میلیمتر و میانگین وزن 03/0 ± 53/3 گرم در 5 تیمار، همراه با سه تکرار به م...
This study aimed to evaluate the effects of using Artemia franciscana enriched with cod liver oil and vitamins C and E on the growth, survival and stress resistance of juvenile Sepia pharaonis (Pharaoh cuttlefish). Twenty-five days after hatching, the larvae of S. pharaonis were transferred into culture tanks with an average length of 15.97±0.15 mm and average body weight of 3.53±0.03 g, in ele...
Increasing marine microplastic pollution has detrimentally impacted organismal physiology and ecosystem functioning. While previous studies document negative effects of microplastics on coral reef animals, the potential responses organisms such as large benthic foraminifera (LBF) are largely unknown. Here, we impact heterotrophic feeding behavior LBF. Specimens Amphistegina gibbosa were incubat...
Feeding farmed Artemia with yeast heat shock proteins is a novel way to protect them from stress conditions during the culture. In this study, the effect of feeding with stressed new identified Saccharomyces cerevisiae strain YG3-1 yeasts (containing induced heat shock proteins) on the survival of Artemia in stress conditions, was evaluated. For this purpose, heat shock proteins 82 (Hsps 82) o...
