Nanoencapsulated Clove Oil Applied as an Anesthetic at Slaughtering Decreases Stress, Extends the Freshness, and Lengthens Shelf Life of Cultured Fish.

摘要: In the aquaculture industry, fish are stunned using a wide range of methods, but all them trigger stress responses and affect flesh quality. Chilled water is considered one most efficient even this not stress-free experience for fish. Anesthetics included in ice slurry or could decrease delay loss work, we analyze effect clove oil (CO) nanoencapsulated β-cyclodextrins (β-CD) (CO + β-CD), incorporated stunning bath, on response organoleptic attributes fresh marine freshwater from four economically important species: Atlantic salmon, European seabass, Nile tilapia, Rainbow trout. CO β-CD reduces time required to induce anesthesia, independently salinity, habitat temperature. The plasmatic glucose cortisol levels decreased species, although concentrations varied between species. Moreover, lactate level differed use extended shelf life species studied (by 3-7 days). conclusion, encapsulated anesthetizing can be regarded as an improved fish-stunning technique that anesthesia-induction time, decreases response, extends
