Shell colour variation in farmed Litopenaeus vannamei: Comparison of white shell (regular) and brown shell (unusual) L. vannamei

Author(s): B. Madhusudana Rao, P. Viji and Jesmi Debbarma | Published: 12/4/2017 | 144 views

The regular shell colour of farmed Litopenaeus vannamei is off -white to greenish-white but instances of L. vannamei with brown-shell colour do occur in farmed shrimp. A study was conducted to determine if there were differences vis-à-vis shell colour, meat colour, meat composition and meat texture. White-shelled vannamei was determined to be better in terms of meat composition and texture profile but brown-shelled vannamei yielded a more brightly red-coloured cooked product.

Self-use manual on group formation and group certification of small-scale aqua-farmers

Published: 9/1/2012 | 2855 views
Responding to the emergent stakeholder concerns such as environmental sustainability, social equity, animal health and welfare, food quality and safety has become an immense challenge to the aqua-farmers. Certification acts as a tool of communication between the primary producer and the interest groups that assures them of a quality and safe market produce originated in an environmentally and socially accountable production system, however, aquaculture mostly being an enterprise of small and marginal farmers, obtaining certification as individuals is financially prohibitive and impractical. An innovative solution for this is ‘group certification’, which divides the cost and responsibility among the partners, enabling them to attain accreditation for their production process and remain in the industry.

This manual is expected to assist small scale aqua-farmers in the region by providing guidelines to implement BMPs through a cluster/group management approach and access markets through participating in group certification programs of their choice. This can also be used by the field extension officers and certifiers who are directly involved in the process and other parties who are interested in being informed about the concepts and practice of aqua-farmer group formation, group functioning and certification.

Draft Guidelines on Aquaculture Society Certification

Published: 31/3/2010 | 3239 views
These draft guidelines aim to support farming societies / groups to seek certification from independent third party certifiers. They could also be used for proposing voluntary branding by the Aqua Societies themselves.

The draft guidelines are based on the deliberations (keeping in mind the challenges faced by the small scale farmers and the stringency of standard set by certification bodies) of the inception meeting on Aquaculture Society Certification held at Kakinada, India, from 1-2 September 2009. The meeting was attended by leaders of farmer societies, representatives of certifying bodies and central organisations / institutions, in addition to representatives of MPEDA, NaCSA and NACA.

Report of the Beijing Expert workshop on Guidelines for Aquaculture Certification

Published: 29/5/2008 | 3229 views

This document provides the report of the Beijing FAO/NACA/Government of China Expert Workshop on Guidelines for Aquaculture Certification, Beijing, China 6-8 May 2008. The Expert Workshop on Guidelines for Aquaculture Certification was held in Beijing, P.R. China from 6 to 8 May 2008, hosted by the Government of China. The workshop was jointly organised and conducted by FAO, NACA, the Chinese Academy of Fisheries Science and the Department for Certification and Accreditation Administration of the People's Republic of China. The workshop is the fifth in a series of workshops and consultations to prepare the international guidelines for aquaculture certification. This workshop had a strong emphasis on aquaculture products from China, and explored opportunities and challenges for implementing the certification guidelines in China towards improving overall aquatic production and trade of aquaculture products nationally, regionally, and globally. The Expert Workshop was attended by 65 participants, including aquaculture experts and stakeholders from government agencies, private business, and agencies involved in certification schemes and food safety from China, as well as international experts from FAO, NACA and SEAFDEC. The workshop considered that international guidelines for aquaculture certification are of significant relevance to the current development of aquaculture and aquaculture certification schemes in China, providing a useful basis for development of standards and mechanisms for certification of aquaculture products in China. The participants provided a number of specific recommendations to the draft version of the international guidelines and implementation issues and mechanisms as detailed in this report.

Report of the FAO/NACA/Gov. Brazil Expert Workshop on Guidelines for Aquaculture Certification

Published: 5/10/2007 | 2942 views
This report is the final draft of the FAO/NACA/Government of Brazil Expert Workshop on Guidelines for aquaculture Certification held in Fortaleza, Brazil during 31 July - 3 August 2007.

The workshop was attended by 57 participants from 13 countries, including several major aquaculture producing and consuming nations. The participants included experts from government agencies, private business, experts involved in certification schemes and food safety, and non-government organizations.

The workshop gave stakeholders in the Americas a unique opportunity to get together with international stakeholders to discuss certification and in particular the development of the draft FAO/NACA guidelines for aquaculture certification. The workshop participants worked in groups to further develop and build consensus on the guidelines. The process and the development of the guidelines were supported by all participants and it was agreed to continue the process to develop the guidelines document further after the workshop.

The workshop recommended that there is a strong need for an aquaculture certification guideline document to inform and guide stakeholders towards responsible and sustainable aquaculture. The first draft guideline document based on the meeting in Bangkok, Thailand in March 2007 is a good base to further develop the guidelines. Overall the guidelines are on the right track but more work and stakeholder input is still needed to finalize the document. The workshop noted that it is important to have a set of minimum requirements in the final version of the guidelines document. A number of comments related to this chapter in the guidelines were given at the Brazil workshop and the chapter should be developed along these recommendations and comments.
