Baitbox Frozen Bluey
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 resembles 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 bait when using baits of equivalent size.
You can use Blueys in exactly the same way as mackerel, Fillets, Chunks, Slithers, Strips, Whole or Head and Tailed. Slithers for Whiting, Chunks for Dogfish and Panelled Strips for Ray especially. For the latter, I generally cut a strip off of about 3-5inches and whip it on to the hooks. Do not strike straight away as Ray is scent feeders and often the first knocks you feel are the fish searching around trying to locate the bait with its mouth.
