Location codes.
Hi Robert and others.
Location codes are important. A fish can be importet with the same scientific name and still be different species all though they look the same.
Many of the south american annuals with many locations, represent in fact a species, or a group of species, that appear the same. For instance Aus. nigripinnis strains cannot always be crossspawned with good results. The eggs will be less vital and fewer will survive. This is due to the fact that within the same species, the different strains can differ genetical. Roger Brousseau has also mentioned for me that when he tried to cross spawn two different Simp. boitonei locations, the result was poor and gave less than if spawning them serperately.
Also when it comes to extinct populations that we are fortune enough to still have in our aquariums, its good to know that we have the right one.
However, I dont think a fish without a location code is without value. As I have mentioned for you before, the most beutiful Nematolebias whitei I have seen is an old unnamed aquarium strain and I would always prefer this one instead of the SBJ-strain.
I also keep serverel endangered goodeids that does not have a location code. The fact that they are alive and still being a fish represents a value, and if the species itself becomes extinct in the wild, its better to have animals without location codes than no animals at all. I have an unnamed strain of Ataeniobius toweri and one Girardinichthys viviparus and I wouldnt trade them with a strain with a code. They are good fish anyway and are doing well for me. Why should I give them away, and to whom? Theya re fine where they are.
So my point is: dont mix fishes with a different location code, keep them "clean" if possible, but dont think that a fish without a location code is a poor fish! It can prove to be the only fish of its kind one day!
