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 (See the Smolt [Section 8] & PTI [Appendix 7 revisions of July 2019]), 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 includes 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.

March 2, 2020: 62-day Public Consultation on ASC Shrimp Standard

(PS: period extended to end on May 18, 2020)

ASC sought feedback on changes we propose making to improve the current ASC Shrimp Standard v1.1. The proposals below are for revision are Shrimp-specific and ASC wants to make changes as soon as possible to improve the reach and relevance of the ASC Shrimp Standard:

New freshwater species – by expanding the scope of the standard to include some key freshwater species, more producers will be able to demonstrate their responsibly produced shrimp through certification. We have proposed new metrics for existing Standard indicators for these species. You can help by reading the short summary (Doc #3) and the full rationale for the proposed metrics (Doc #4) and letting us know if you have any feedback.

We also need to add new indicators to the ASC Shrimp Standard to ensure the environmental impacts of these new freshwater species are rigorously assessed. We have evaluated ASC’s existing species standards and proposed additional indicators to transpose into the Shrimp Standard. Read the short summary (Doc #5) and background documents (Doc #6 & Doc#9) and provide your comments.

Marine species revision – We have revised all the metrics included in the current Shrimp Standard and updated them based on current production data and recent research. We furthermore assessed if the specific metrics for P. vannamei and P. monodon can also be used to certify other Penaeid shrimp species.  Please help by reviewing the short summary (Doc #7) and the rationale for the proposed metric changes (Doc #8) as well as the background document on new marine shrimp species (Doc #8a) and let us know if you have any additional information that could inform this.

Other changes

The proposed Shrimp Review amendments and considerations are undertaken concurrently with the release of the ASC’s new Metrics Methodology (also went to Public Consultation).

Based on the recent research regarding detailed phylogenetic analyses of several shrimp within the family Penaidae (Ma et al., 2011) and the review by Flegel (2007) the Penaeus genus will be used for all potential new species. It is recommended to also apply this change to Penaues (Litopenaeus) vannamei within the revision of the ASC Shrimp Standard. In the interim, both genera can be used interchangeably (e.g. Penaeus (Litopenaeus) vannamei’) in the documents going through to Public Consultation.

  • For further information, please view the public webinar that was held on the 8th of April 2020 for all interested stakeholders:

The slides of the webinar can be downloaded here.

Next step…. Revisions will be ready for our next public consultation in August 2020.

ASC are working on several topics that are also relevant to other species. These will result in indicators in the new aligned ASC Farm Standard. This will take longer than other revisions relevant just to Shrimp so in the meantime we are working to finalise some revisions to the ASC Shrimp Standard. You can also find updates on Antibiotics, Marine litter and aquaculture gear, and Mangroves and Wetlands on the ASC Farm Standard development pages.

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 (kathrin.steinberg@asc-aqua.org) if you have any relevant data re. the above species. Thank you!
