Effects of different wavelengths and intensities of visible light on the hatching success of Acartia tonsa Dana eggs.

摘要: Mass production of copepod eggs in intensive systems has recently been demonstrated to be economically feasible; a few companies producing have established. It is well documented that water physiochemical variables could significantly influence the hatching success Acartia tonsa Dana, 1849 (Copepoda: Calanoida) eggs. This information important end users order achieve predictable output nauplii when for live feed marine larviculture. The effect different wavelengths and intensities light on 48-h egg (HS) fresh cold-stored (2 °C) A. were examined present study. No correlations observed between HS environment or cold they hatched at 400 630 nm 0.0016, 1, 5 16 µE m−2 s−1. Fresh displayed highest declined with time storage. However, being same age showed similar regardless intensity wavelength, including darkness. We suggest produced cultures can without any concern environment.
