Strange situation here and I do not see where to fix it.
I use JabRef-4.3.1 for my references. I've created a new KOMA-Script report
and used the JabRef -> LyX icon to insert a reference and bibliography
reference. As a test I tried to preview the document only to have lyx tell
me there are deprecated font types, e.g., \sc, in the bibtex entry.
Looking at the bibtex entry in JabRef I see expected ASCII text in bibtex
format. I tried exporting that entry but did not find a format that printed
in plain ASCII text. Sigh.
Here's the last few lines from lyx error log:
! Class scrreprt Error: undefined old font command `\bf'.
See the scrreprt class documentation for explanation.
Type H <return> for immediate help.
...
l.7 ...l of Fisheries and Aquatic Sciencess}, {\bf
37},
The entire log is attached; so is a MWE. If I need to send the actual JabRef
entry I'll figure out how to provide that in a useful format.
In LyX the citation type is authordate3.
Looking at the document's .lyx file I don't see the bibiographic entry at
all.

You should note that since 1994 LaTeX2e provides a new font selection scheme
called NFSS2 with several new, combinable font commands. KOMA-Script
classes had defined the old font commands like `\sc' only for compatibility
with old LaTeX 2.09 document styles of Script 2.0. Nevertheless, these
commands are deprecated and undocumented at least since 2003. Since 2013
KOMA-Script classes warned about soon removement of these deprecated commands.
Now, after two decades of LaTeX2e and NFSS2, these commands will not work any
more. If loading a package results in this error message, you should contact
the author of that package and ask him to replace the deprecated font command
`\sc', e.g., by `\normalfont \scshape `. Otherwise you should reconfigure
or replace the package. If you have used the old font command `\sc' yourself,
you should replace it, e.g., by `\normalfont \scshape '.
To make it work for now, you can use the already also deprecated class option
`enabledeprecatedfontcommands'.
