Choosing the best model in the presence of zero trade: a fish product analysis

The purpose of the paper is to test the hypothesis that food safety (chemical) standards act as barriers to international seafood imports. We use zero-accounting gravity models to test the hypothesis that food safety (chemical) standards act as barriers to international seafood imports. The chemical standards on which we focus include chloramphenicol required performance limit, oxytetracycline maximum residue limit, fluoro-quinolones maximum residue limit, and dichlorodiphenyltrichloroethane (DDT) pesticide residue limit. The study focuses on the three most important seafood markets: the European Union’s 15 members, Japan, and North America.

Recent advances in fish processing and product development

There are good possibilities for expanding the consumer sector in both the traditional and nontraditional marine products. Frozen shrimp continues to be the item of highest demand in foreign markets. Individual quick frozen (IQF) prawns which are indeed value added products and have already penetrated international markets elicit export incentive from development agencies like the Marine Products Export Development Authority. With the projected potential of 1.8 lakh tonnes of cephalopods against the current yield of 13,000 tonnes, there are good prospects of increasing exports of frozen squid and cuttlefish. The technology of packing fish in retortable pouches as an alternative to canning has now been perfected. Salted fish mince has good market potential in India and abroad.

Ensiled product from fish by microbial fermentation

Fish ensilage for animal feed stuff was prepared from Jew fish (Pseudosciaena spp.) and Silver bellies (Leiognathus spp.) by fermentation with pure culture of Lactobacillus piantarum NCIB 6105. The precooked ensiled product gave better product of fish silage (high content of lactic acid, about 5%). Protein Nitrogen content ranged between 1.76 to 1.94%. During storage for one year, the Protein Nitrogen loss was not significant. The material can be used as a supplemental animal ration.
