The objective of this study was to evaluate the effects of three levels of lipids in the diet on growth, metabolism, and intestinal and hepatic histopathology in discus fish (Symphysodon aequifasciatus). Fish were stocked in quadruplicate in aquarium (50L) and were fed experimental diets containing three levels (3%, 10%, and 14%) of dietary lipids (LP). At the end of the trial, no significant differences in growth performance were observed.

Article Synopsis
  • Live food is important for the growth of neotropical fish larvae, but using it can raise production costs; this study tests the use of complete diets with different moisture levels as a cheaper option for surubim larvae.
  • A total of 3200 three-day-old surubim larvae were fed exclusively on Artemia for five days, then given diets with moisture levels of 47%, 35%, 24%, and 8% in a controlled trial over 21 days; results showed the 24% and 8% moisture diets led to better weight gain and length.
  • Enzyme activity analysis indicated that the 47% moisture diet increased certain liver enzymes and showed negative liver effects, while the 24% and

Background: In February 2016, a new fungal disease was spotted in wheat fields across eight districts in Bangladesh. The epidemic spread to an estimated 15,000 hectares, about 16 % of the cultivated wheat area in Bangladesh, with yield losses reaching up to 100 %. Within weeks of the onset of the epidemic, we performed transcriptome sequencing of symptomatic leaf samples collected directly from Bangladeshi fields.

This work is a contribution to the development of flow sensors in the oil and gas industry. It presents a methodology to measure the flow rates into multiple-zone water-injection wells from fluid temperature profiles and estimate the measurement uncertainty. First, a method to iteratively calculate the zonal flow rates using the Ramey (exponential) model was described.
