Our previous study showed that a diet enriched with 400 g of carp per week improved plasma lipids in subjects after aortocoronary bypass (CABG). The aim of the present study is to determine whether the different carp farming systems have an impact on the effects of carp meat in secondary cardiovascular prevention. We examined 3 groups of patients after CABG over a 4-week period of spa treatment (108 persons, 73 males, 35 females, age over 60 years). We found no differences in baseline values of blood pressure or plasma lipids. The patients were given a standard spa diet (controls; N=36) or a diet enriched of 400 g of carp meat per week, enriched omega 3 (N=37) or cereal carp (N=35). Plasma lipid parameters were examined at start and after 4 weeks in a routine laboratory setting. Group consuming omega-3 carp showed the largest decline in total cholesterol, LDL cholesterol, triglycerides and an increase in HDL cholesterol (all p<0.01). We found that carp meat from the two production systems showed significantly different effects on plasma lipids. Further trials should be performed to clarify the exact causes of the differences.

OBJECTIVES: Fish is the major source of n-3 polyunsaturated fatty acids (n-3 PUFA) which are well known to have positive effects in prevention of cardiovascular diseases. This study investigated the possibility to produce common carp with defined flesh quality using finishing feeding strategy and predict changes of fillet FA by a dilution model. METHODS: During the 110-day experiment, fish were fed diets with two different vegetable oils (rapeseed/linseed blend, VO; olive oil, OO) only, or with a subsequent fish oil (FO) finishing treatment for 30 or 60 days. Fillet FA composition was measured and data were compared to the ones predicted by the dilution model. RESULTS: The FO finishing treatment resulted in the higher percentage of SFA (from 19.1% to 23.6%; p<0.001), MUFA (from 46.8% to 51.9%; p<0.001), n-3 PUFA (from 3.6% to 7.4%; p<0.001) and lower n-6 PUFA (from 30.5% to 16.9%; p<0.001) and n-6/n-3 ratio (from 8.7 to 2.3; p<0.001) in groups previously fed the VO diet and in lower MUFA percentage (from 67% to 63%; p<0.001) and n-6/n-3 ratio (from 8.2 to 2.8; p<0.001) and higher n-3 PUFA percentage (from 1.5% to 4.5%; p<0.001) in group previously fed the OO diet. The dilution model gave a good prediction for fillet FA changes (slope of the regression line 0.97-1.00; R2 value of 0.992-0.996). CONCLUSION: The finishing feeding strategy is suggested for production of common carp with a required flesh FA composition for purposes of special nutritional needs, especially for primary and secondary prevention of cardiovascular disease.

There is evidence that n-3 highly unsaturated fatty acids (n-3 HUFA), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are beneficial for human health, especially for the cardiovascular system. The sources of n-3 HUFA, including EPA and DHA, are scarce in diet consumed by the Czech population. Thus, it would be beneficial to generally increase fish consumption and also to increase the content of the beneficial fatty acids (FA) in locally produced fish and other products. Therefore the overall aim of this paper was to review factors influencing lipid content and composition in common carp, which is the major cultured fish in the Czech Republic, and to identify long term sustainable ways for increasing the beneficial fatty acids in the carp flesh. We conclude that there are several ways to improve the FA composition of common carp in the traditional pond production. High amount of natural food, good supplemental diet containing high level of alpha-linolenic acid (ALA) and suitable processing and cooking were identified as the most important ones.
