Bluey is a bait which has become immensely popular in UK sea fishing in recent years, and has been heavily hyped online and by the angling press. Bluey is a very good and versatile bait (although whether or not it lives up to the hype is open to debate). It can be used in smaller sections as a general sea fishing bait, or used whole or in fillets or flappers to temp the largest of species such as conger, large bass and big cod.
Many anglers are confused about what exactly bluey is. To start with bluey is a nickname, presumably given because of the vaguely blue colour of this fish. It is officially called Pacific saury (or to give it its scientific name Cololabis saira). They are a slim and streamlined fish with short fins and pointed snouts – it is accurate to describe them as looking something like a cross between a mackerel and a garfish. Their natural environment is the North Pacific where they swim in mid-water mostly feeding on plankton and the larvae of fish. They are an important part of the North Pacific food chain and are preyed upon by fish such as tuna and sharks. In Asia and parts of Russia the Pacific saury are a very important food fish and are considered a delicacy in parts of South Korea and Japan, where they are so popular Pacific saury ice cream is even available! However, they are yet to catch on as a food fish in Britain and the vast majority that are imported are used as fishing bait.
Unless anglers are prepared to travel to the North Pacific there is no chance of catching blueys on rod and line, and since they are not a common food fish in the UK they are not usually available from supermarkets (although places specialising in Asian food may stock them). That leaves the fishing tackle shop as the only place where blueys can be reliably purchased in frozen form, usually in packets of three or four. All of the UK major national frozen bait companies also supply bluey. Many anglers keep a supply of bluey in the freezer, ready for a fishing trip at short notice, or for winter fishing when fresh bait is hard to get hold of. Frozen bluey will keep perfectly well in a domestic freezer for several years.
Better than Mackerel?
Oily fish (such as herring and mackerel) are fish which have their oil throughout their body, contrasting with whitefish (such as cod, plaice and haddock) which have the oil in their bodies concentrated in their liver. Oily fish clearly make the best baits as the oil, guts and other juices leak out of the flesh and create a scent trail in a way that does not happen with whitefish.
Bluey are very oily indeed, more so than mackerel, which leads people to believe that bluey will put out more of a scent trail and take longer to become washed out than an equivalent sized mackerel bait. Although there is no definitive proof many anglers claim that catch rates are better when using bluey instead of mackerel, and although this is a species found nowhere near British waters it still catches all manner of British species.
Bluey Bait Presentation
As stated bluey is a versatile bait which can be used to catch a wide range of fish across British waters. For general sea fishing with hooks sized 1 to 2/0 strips of bluey around 3 – 9cm (1 – 3½ inches) can be used. Although bluey is not a particularly tough bait it will stay on the hook well if the hook is threaded through several times (as the picture above shows). Using a strong but relatively fine wire hook such as the Kamasan B940 Aberdeen is a good idea as this hook provides good bait presentation but is strong enough to handle any larger species which may take the bait. Sections of this size can also be used as a float fishing bait to catch mackerel, pollock and wrasse. For larger species such as cod, bass, and rays larger strips of bluey can be used, but if the size of the bait is increased it is a good idea to use bait elastic or cotton to secure it to the hook. If targeting larger species then stepping up to a stronger pattern of hook such as the Kamasan’s B950u Uptide hook is a good option.
For the very biggest fish such as conger eels and tope then blueys can be cut in half and both sections used as full baits. The head of a bluey can be hooked either through the eyes or through the roof of the mouth with size 6/0 – 10/0 hooks. Alternatively large fillets can be cut from the flanks of blueys, or they can be cut into flappers in the same way that mackerel are.
