Regular operational reviews ensure the continued efficiency of the various ASC standards. They are focused on areas where the performance of a particular standard is not as anticipated, or may not deliver on the intent as set out in the ASC’s Theory of Change.

Review – Shrimp

The goal of the ASC standards is to provide a means to measurably improve the environmental and social performance of aquaculture operations. Each farm standard undergoes periodic review every three to five years to ensure their continued effectiveness. During the most recent review period, it was determined that improvements would be made to the standards for salmon (Smolt [Section 8], PTI [Appendix 7]), pangasius, freshwater trout and shrimp. It is not intended that these will constitute full reviews of the standard, rather a focused review on areas where the effectiveness of a particular standard is not as anticipated during the Aquaculture Dialogues or will not deliver on the intent as set out in ASC’s Theory of Change.

The revision process of the Shrimp Standard will include a review of the current antibiotic-related requirements, and of those regarding mangroves, farm management, broodstock and the species-scope. Efforts will be made to review the applicability of these requirements, including the monitoring of antibiotic use and the application of antibiotics in a responsible manner, to establish a unified approach to antibiotics across all ASC Standards. 

Update – December 2019:

ASC is currently looking for farming (and/or research) data for the following species:

  • Giant tiger prawn – Penaeus monodon, 
  • Whiteleg shrimp – Penaeus vannamei
  • Giant freshwater prawn – Macrobrachium rosenbergii
  • Lousiana crawfish – Procambarus clarkii
  • Crayfish – Cherax spp. 

The data will be used for metric-setting and will be anonymised. Data is being sought for all criteria/indicators in the Shrimp Standard with a metrics dimension, and with a special focus those related to feed use, effluents and survival rate. For instance:

  • Chloride concentration or specific conductance;
  • Survival rate;
  • System type (fed and aerated, fed and non-permanently aerated, non-fed);
  • Stocking density (not covered in the current standard);
  • % PLs that are SPF or SPR;
  • %PLs from closed loop hatchery (origin of PLs);
  • % FM/FO in the diet (or general information on feed formulation used);
  • % non marine ingredients in the feed;
  • FFER (forage fish efficiency ratio, can be calculated from eFCR and %FM in the feed);
  • N effluent per tonne of shrimp;
  • P effluent per tonne of shrimp;
  • Settleable solids concentration in the outflow / data on general water quality;
  • eFCR;
  • Protein retention efficiency.

Please contact Kathrin Steinberg, the ASC Performance Data Coordinator ( if you have any relevant data re. the above species. Thank you!
