Welcome to the uFish Ireland website, where you can find all the details you need to go angling in the Foyle and Carlingford catchments.

Length to Weight Conversions

These tables give a very good indication of the weight of each species of fish covered;- Tope, Pike and Salmon. By using these tables you can minimise the amount of stress and potential damage to your catch, returning them to the water in a better condition.

 

Tope

(reproduced by kind permission of the UK Shark Tagging Programme)

Tope anglers are encouraged not to weigh tope (for reasons of welfare of the fish) unless they have an appropriate weighing sling.

An indication of weight can be obtained by measuring length and obtaining an estimate of weight using a length to weight conversion chart, similar to the one that follows.

Total length is measured from tip of nose to end of tail.
