Nutrient‐efficient catfish‐based aquaponics for producing lamb's lettuce at two light intensities

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 11, Page 6541-6552, 30 August 2024.
Abstract BACKGROUND Aquaponic systems are sustainable processes of managing water and nutrients for food production. An innovate nutrient‐efficient catfish‐based (Clarias gariepinus) aquaponics system was implemented for producing two cultivars of two leafy vegetables largely consumed worldwide: lamb's lettuce (Valerianella locusta var.

Mismatches between cues can occur when they persist in the environment for different periods of time, potentially increasing uncertainty about which mate to choose. We found that patches with a mismatch between cues signalling female mating status led to intermediate survival costs in males, with the substrate cues left by females being instrumental ...
