Aberaeron Crabbing Project

Recreational crab fishing has, and continues to be, a popular activity for holiday makers with many a British seaside town playing host to this traditional summer pastime.

Crab sketch

People use a variety of fishing gear and baits, along with techniques passed down within families from generation to generation. We are interested in understanding what influences the numbers of crabs caught, how often crabs are caught and how the food that is used as bait influences the population dynamics of crabs in high recreational crab fishing areas e.g. Aberaeron Harbour, Ceredigion, Wales.

We need your help

We are therefore looking for help from the general public in gathering information on your crabbing activities in order to address these scientific questions. We have marked approximately 1,000 crabs with small coloured markers (see the picture below) so we can see how often individual crabs are caught.

We are also interested in:

  • the type of fishing gear used e.g. line with a hook, line with a mesh bag

  • the type of bait used e.g. none, bacon, fish (if using fish it would be very useful to know the species or at least whether it is an oily or white fish), limpets

  • how long you fished for

  • the total number of crabs you caught

  • the number and identity (i.e. blue 21, yellow 89) of tagged crabs caught and

  • an estimate of how much bait you used or discarded into the harbour when you had finished fishing
