Pellets have certainly increased in popularity over the last decade as they catch small & large fish due to their various sizes, which range from micro feed pellets of no more than 1mm to gigantic halibut pellets over 20mm. They are also very easy to hook & very easy to catapult /throw at distance with a high degree of accuracy.
Pellets also come in many different flavours, many of which have been designed primarily to catch barbel & carp.
Flavoured Pellets are produced by all the large bait companies and there is a vast array of different flavours, all designed to catch specific fish. They can be either fishy in flavour or seriously sweet depending on the flavour chosen - best used on hard fished waters where you want to offer a new flavour to the fish.
Carp Pellets have little or no concentrations of oil meal which makes them ideal for venues where regular high oil pellets such as trout & halibut have been banned.
Expander Pellets are tough floating pellets which need to be processed within a pellet pump in order to soften them for use on the hook or as loose feed - these pellets can also be flavoured during the process of preparation.
Halibut Pellets & Trout Pellets are high oil pellets packed with nutritious fish meal which fish adore, they come in many different sizes which can be used either broken down in grounbaits, stick/bag mixes or drilled out and used on a hair rig.
Micro Feed Pellets are similar to carp pellets as they have a low or no concentrations of oil and are typically around 1 or 2mm in size. They are designed to be soaked and then moulded around flatbed feeders or used as loose feed in pole pots.
