Issues such as habitat damage; pollution of groundwater; escapes and disease transfer. Feed sustainability can be a concern but is being addressed independantly by this producer.
The king prawn (or whiteleg prawn, white shrimp) belongs to the largest of the prawn and shrimp family, the Penaeidae. It is a native species of the Eastern Pacific coast. Its lifecycle may be divided into 6 stages or phases, from embryo to adult, which it completes in one year. The age of sexual maturity varies from 5 to 7 months. They can live up to 2 years in the wild although farmed prawns are usually harvested at 6 months.
