John Birkett on Larvae Culture and the Human Condition

 

Lots of water has passed under the bridge the in the last 30 years.  Change and evolution have come to shrimp larvae rearing.  Water exchanges with the help of antibiotics and drastic water exchanges with lots of chemical help have morphed into zero water exchange with lots of probiotics.  Academically approved genetic selection of pedigreed shrimp families is being replaced by using microsatellites for genetic selection.  Wild broodstock for the production of seedstock have been replaced with domesticated broodstock.  The ways of humans, however, have remained the same, especially when money enters the equation.  That’s when humans get tricky.  Black turns to gray and even to white if necessary.  Hatchery managers will defend whatever point of view will help them survive even if its runs counter to their common sense.
