Abstract

Feeds and feeding practices have a major influence on sustainability of intensive fish farming, in addition they affect many quality attributes of cultured fish species. In the framework of the “I.R.IDEA” project, the composition of feeds, feeding practices and major quality traits of fish produced by the local trout farming industry were investigated with the aim at seeking for possible distinctive features and/or suggesting novel feeding protocols which could add value to the regional trout supply chain. The survey has shown that the locally used trout feeds are quite different in formulation and nutrient characteristics resulting in variable quality attributes of the fish flesh. This actually does not allow acknowledgement of particular features of the local trout farming process/products. An agreement between fish farmers and the feed-mill industry for a sustainable range of raw materials–nutrients specifications to be set in trout feeds, is strongly recommended as an effective way to characterise local trout products and supply chain. Also the feeding practices and protocols currently adopted by the local trout farmers do not possess peculiar features. On this subject we have tested cyclic feeding as a novel protocol being adopted for the first time in commercial trout farms. The results obtained so far have shown cyclic feeding to be a promising practice, resulting in improved economic and environmental sustainability when compared to conventional feeding protocols. Cyclic feeding should be also recommended as a possible tool to characterise local trout farming management and supply chain.
