| Popis: | Dietary fatty acid (FA) composition influences the composition of fish tissues to a greater or lesser extent depending on the proportion of saturated FAs (SFAs) and medium-chain (MC) polyunsaturated FAs (PUFAs) that the feed contains. Our purpose was to evaluate the growth performance and tissue composition of largemouth bass Micropterus salmoides that were fed diets containing soy-derived lipids modified to contain more SFAs and less MC-PUFAs. Triplicate tanks of largemouth bass (∼1.6 g) were fed diets containing fish oil (FO diet) or 50:50 blends of fish oil and low-18:3(n-3) soybean oil, hydrogenated soybean oil (HYD-SBO diet), or SFA-enriched soybean oil (SFA-SBO diet). After 10 weeks, production performance was unaffected by diet, and weight gain (mean ± SE = 518 ± 19%), feed conversion ratio (1.29 ± 0.03), specific growth rate (2.59 ± 0.04% of body weight/d), and feed intake (1.42 ± 0.03% of body weight/d) indicated that all diets were accepted and well utilized.
