Good move – with Black Tiger also a possibility to import.
Now here is the biz – BT are closed thelycum and hold fertilized eggs inside theire bodies unlike vannamei whose eggs get fertilized on leaving the body.
In West Africa plenty of gravid females and many cannot spawn because areas where they want to spawn tend to have very high total dissolved solids.
SO the females hold back spawning and just grow while searching for ideal place to spawn. In this same fashion gravid BT females could enter and be held in a quarantine situation (but with a high TDS – artificial fine silt works) until an MPEDA (or OIE) approval is obtained against required pathogens.
Then gravid BT released into clear water (still controlled) indoor spawning tanks in separate bio-securely run facility (to exclude entry of disease).
Of course same could happen in US or with any other origin/species.
