I know that the only subspecies of Talapia you can stock "legally" in Tx. is the Mozambique variety. I just came across a really cool fish food mrkt. supplier in Conroe. They have some huge Talapia, mainly for eating, but I do not know what subspecies they are. Are there any subspecies of Talapia that can make the winter here in Tx.? I am wondering if some of the other subspecies, despite being illegal, might be able to do well here in the winter. Wonder if they spawn at the same rates as the Mozambique variety?
