Questions
Question (1)
What is your opinion on the ongoing discussion regarding the taxonomy of the genus Penaeus?
As someone that is not a taxonomist, when I began working with shrimp I was not aware of it and simply used Litopenaeus because it was the name that I mostly read in recent publications. Today I came upon a recent article published in Aquaculture "Making sense of the taxonomy of the most commercially important shrimps Penaeus Fabricius, 1798 s. l. (Crustacea: Decapoda: Penaeidae), a way forward" that drew my attention to it. There is also an older article by Tim Flegel that deals with this (See below). I am considering using his recommendation of placing the sub-genus in parenthesis, e.g., Penaeus (Litopenaeus) vannamei, because I find his arguments reasonable and what the Yang et al. (2023) study found, but I am concerned because it seems that the use of the sub-genera as genera is very prevalent already.
