Nice conversation over here!
About wc rays exportation from Brazil, there's a limited quote and limited size allowed.If I'm not wrong, 100 per year, with a maximum size disc of 30 cm, diameter. So, that limits the collection of breeding adults, at least for the black ones(the ones I intend to work with), I guess.
A collector/ exporter cannot sell offspring unless he is also a commercial breeder, which needs an specific license. That license needs to be approved first, by presenting a breeding detailed project- not a peace of cake.
Here, in Brazil, there's no possibility of becoming a commercial breeder by chance.For instance, if one has a pair of rays that breeds for him, he can't sell offsprings legally. For that, he must have a specific license first, as stated before. An effort of patience indeed!
About my situation: the place where I intend to start my project, have a hot weather the hole year and flowing water with the specifications stated before. About food, the farm where I intend to work already have plenty of native river shrimp and fishes,which can be net collected anytime. Besides, it's at the littoral , so I can by fish goods direct from fisherman very cheaply. Not far from there, there are prawn farms, where I can get post larvae and discharged shrimps for almost nothing. So, as you can see, costs to run that breeding facility will not be huge.
About exportations,is just another opportunity. My intention is to be a commercial breeder and, if viable, an exporter of captive bred stingrays(not wc).
By captive breeding , I guess I can select breeding pairs by colors , producing attractive variations, from the same population, isn't it?
Well, those are my aspirations, and thank's for every opinion. They are valuable indeed!
