I guess it depends on the philosophy of the breeder and what his/her aim is.
In a commercial situation where getting the fish to marketable size in the
quickest time is the aim and you have them in an intensive set-up I guess
continuous lighting, drip feed, higher temperatures, frequent water changes
and continuous culling will get the most saleable fish out in the shortest
time but on the other hand if you wish to produce the best next generation
for yourself or others then the "natural" approach seems the way to go.
Obviously there isn't a right or a wrong answer here - just preferred
options for a given set of priorities.
