India has a large export trade in fish and fisheries products. There isample scope for further increase of export as well as internal trade of fish and fisheries products if proper quality control measures are taken. This standard, first published in 1985 is intended to introduce uniform methods of sampling to be adopted by various agencies for fish and fisheries products. This revision has been undertaken to update tl,e sampling requirements to help in exercising proper quality control of fish and fisheries products. For the purpose of sampling, fish and fishery products have been broadly classified into following groups: a) Canned fish, b) Fresh fish, c) Frozen fish, d) Dry-salted and dried fish, and e) Fish oils. For each of these groups, a suitable sampling plan has been recommended. This standard is applicable only to fish and fishery products belonging to the above five categories packed in containers. _uA- .
