摘  要:
Study on high-density pond larval-rearing of Nibea diacanthus has been made at Zhao-an county in 2007.Larvae after hatching 4d have been removed from indoor pool into the outdoor earth pond straightly.After raising 42d,about 623,000 fingerlings,with main body length of 5.2cm(4.6 cm.~5.8cm),were gained.The survival rate of larvae was 51.91%.The unit productive force was 47196 fingerlings per 'mu' at average level.Better economic efficiency has been gained.
