Let the whole stew for an hour, and then strain it through a sieve, to use as occasion may require. If you should have no wine, put in some vinegar. The court-bouillon is better after having been served several times than on the first day. It is excellent for stewing crawfish. Any wine will do for
the court-bouillon, even if sour. It is a famous thing for stewing crawfish.
* This is a very proper dish for a Roman Catholic family during Lent. It is always good; only add a glass of wine to it every time you use it. Use it for marinade, &c. &c.
The above recipe is taken from
THE French Cook; or, The Art of Cookery Developed in All It's Various Branches. by Louis Eustache Ude. Formerly Cook to Louis XVI, King of France and at Present Cook to the Right Honorable Earl of Sefton.

The above exists in several editions, the dates of those range from 1813 to 1841.
I reproduce the above as it reminds me of the famous Chinese lu shui sauce (Master sauce) which must be reboiled every few days to keep it from spoiling. And I'm certain that this stock would require that too, after it's first use with poaching or simmering fish. In the past, the court bouillons I have made have been frozen and that eliminates the need for reboiling every few days.
By "after a few times" is meant that the fish flavor becomes more pronounced on the tongue after being used a few times. That is certainly true for the lu shui as well. A necessary.
Parsley roots are a relatively modern addition to the foodstuffs I see at produce markets. I don't recall such as little as 25 years ago.
By way of comparison, here is a court bouillon recipe I found two decades ago.
