Species identification by DNA barcoding
A total of 49 PCR products were sequenced successfully from 49 samples, of which 33 sequences were related to fish eggs and 16 sequences were related to fish larvae. Aligned sequences in a consensus length of 540bp yielded 212 polymorphic sites. The 49 DNA sequences were deposited to GenBank (see sequence accessions MZ461989-MZ462037 and their corresponding sample codes on Fig. 2).
