We introduced blast frozen blueys (Cololabis saira) onto the UK sea angling market in 2007. They are an Extremely Oily fish making them Immensely Good especially for Rays, Dogfish and Whiting. To look at a Bluey it resemembles a cross between a Mackerel and a Garfish. These fish are found all over the Pacific from Japan to the Gulf of Alaska. The oil from a bluey has a far greater viscosity than mackerel or herring and as such remains in the flesh and washes out much slower making it far more effective as a bait when using baits of an equivalent size.
