CSIRO, Tiger Shrimp and Gold Coast Marine Aquaculture

 

Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO) has worked with industry partner Gold Coast Marine Aquaculture (GCMA) to develop a genetically selected strain of tiger shrimp (Penaeus monodon).  Consequently, from November 2013 to January 2014, GCMA is expecting to harvest up to 1,000 metric tons of shrimp.

 

“We have gained progressive cumulative benefits from genetic selection,” says CSIRO acting director Dr. Nigel Preston who is in charge of the tiger shrimp breeding project.  “With every generation there is incremental improvement.”

 

Genetic and viral health screening, along with mating systems developed by the CSIRO, have led to average yields of 15 tons per hectare, and a record high of 24.2 tons per hectare. The industry average for farmed shrimp is less than seven tons per hectare.

 

Shrimp at Sydney fish markets generally retail for between $20 and $30 a kilogram.  The extra-large GCMA shrimp are currently on sale for $27.50 a kilo.  GCMA also produces smaller shrimp that retail for about $20 a kilo.

 

About 50 percent of Australian shrimp are imported, about 30 percent are caught by Australian fishermen and between 15 and 20 percent are produced by shrimp farmers.  A report commissioned by CSIRO showed that the financial gains in shrimp yields delivered so far from the selective breeding program amounted to about $430 million.
