MASGC Project Impacts

Inland shrimp farming operations improve production projects by increasing survival juvenile shrimp

Relevance:

Poor survival of post-larvae shrimp following acclimation to low-salinity waters has been a problem for farmers raising shrimp inland since the beginning of the west Alabama inland shrimp industry in 1999. As post-larvae are a significant expense for inland farmers, improved acclimation techniques were required to increase survival and subsequently improve profit margins.

Response:

A growth trial was conducted at different salinities and temperatures to explore the effects on growth and survival of juvenile shrimp. Another study was conducted to evaluate how various aqueous sodium-potassium ratios at different temperatures impacted survival, growth and osmoregulatory capacity of shrimp. Researchers are transferring research results to local farmers to improve on-site acclimation of post-larval shrimp.

Results:

Alabama producers are now more aware of the effects of shifting temperature and salinity and their effects on shrimp survival. Adoption of these techniques has led to better survival during the production season. Increased survival at acclimation has allowed farmers to increase their production at harvest by more than 500 pounds per acre compared to when the study began in 2008. The annual economic impact is approximately $1,200,000 to date ($200,000 per year).

Recap:

Mississippi-Alabama Sea Grant improved acclimation techniques that inland shrimp farmers in Alabama use, thus increasing survival and production of shrimp by 500 pounds per acre. (2014)
