Juvenile production of the reshwater prawn Cryphiops caementarius (Decapoda: Palaemonidae) under laboratory conditions in Coquimbo, Chile
Two culture experiments from 1995 until 1997 were carried out with larvae obtained from gravid females of Cryphiops caementarius (Molina 1782), to define a methodology in order to produce juvenile using controlled conditions of water temperature, salinity and feeding. Time in culture of larval devel...
