Abstract: An exogenous biomolecular tracing method includes: extracting a nucleotide marker from a marker source organism; combining a basic material with the nucleotide marker to form a nucleotide marked material; exogenously combining an aquatic creature or an aquatic product to form an exogenously-marked aquatic creature or an exogenously-marked aquatic product; and identifying a DNA sample from the exogenously-marked aquatic creature or the exogenously-marked aquatic product with at least one primer pair in an exogenous biomolecular tracing procedure to obtain an exogenously-marked identification result.

Abstract: A biomolecular characteristic identification method includes: breeding a plurality of Taiwan Tilapias in a predetermined environment to obtain a plurality of baited Taiwan Tilapias; seeking at least one nucleotide mark in the baited Taiwan Tilapias to obtain at least one feature sequence marker therefrom; producing at least one design of primer pair according to the feature sequence marker for identification; and identifying an unknown DNA sample of the baited Taiwan Tilapias with the at least one primer pair in a biomolecular tracing procedure to obtain an identification result.

Abstract: A recombinant vector, transgenic fish egg using the same and biomaterial using the same are applied to provide a transgenic fish that secreting recombinant human procollagens or collagens, and further to provide the biomaterial having the recombinant human procollagens or collagens and extract the recombinant human procollagens or collagens from the part(s), having the recombinant human procollagens or collagens, of the transgenic fish.
