Pulsed lighting is characterized by frequency (number of on/off cycles that occur per second) and duty ratio (ratio of ‘on’ time to ‘off’ time in one on/off cycle). The concept is to provide pulses of light at specific frequencies in order to optimize net photosynthetic rate.

Sensible heat is the energy required to change the temperature of a substance with no phase change. The temperature change can come from the absorption of sunlight by the soil or the air itself. Or it can come from contact with the warmer air caused by release of latent heat (by direct conduction). (https://climate.ncsu.edu/learn/)
Common term used to describe the cultivation of organisms in land-based ponds. Various pond designs are used in different stages of an organism's development, such as spawning ponds, wintering ponds, fry ponds and ongrowing ponds. (AQUALEX. Multilingual glossary of aquaculture terms, 1998)
Diel vertical migration, also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The migration occurs when organisms move up to the epipelagic zone at night and return to the mesopelagic zone of the oceans or to the hypolimnion zone of lakes during the day.
