Fish schools exposed to these implied infection cues developed infections, but the rate of infection increase was slower and the peak infection density was lower than that seen in schools exposed to the control. The data demonstrates that guppies show subtle behavioral responses triggered by infection...

Fluorescence meters, also referred to as fluorometers, measure peak wavelengths in the regions of 685–690 nm (red) and 730–740 nm (far-red, near-infrared). Fluorescence ratios of red and far-red regions [23,27,28] enable direct estimates of chlorophyll content based on regression ...
As the world population recently reached 8 billion people, the demand for fish is continuously increasing. While production from fisheries has reached its peak, it cannot increase further without irreversible effects on the environment and marine and freshwater biota. The solution could be farmed fish...
The separation method was validated as follows: The linear correlations between peak area and standard concentrations were found to be high in the range of 0.5–50 µg·mL−1. The resulting linear equations were obtained with R2-value for a six-point calibration graph >0.99, and the slope...
