One of the key reasons behind any fish's addiction to trout and halibut pellets is the oil that is incorporated in them. Used as a powerful attractant as well as a concentrated energy source, this oil is the exact same product that is used in the manufacture of the vast majority of expanded pellets used in the aquaculture and bait industries. With a very distinctive oily fish aroma and taste, Trout/Halibut Pellet Oil can be used very effectively on or in most baits, but is more suitable for use during the summer months due to its viscous natural state that makes it semi-solidify in cold conditions. The recommended inclusion level in base mixes is 20-30ml/kg.
