Hi everyone

Can anyone tell me the growth rate in river barbel.Im not sure
if its an exact science,but im sure one of you guys will know.
The angling club ive recently joined have just stocked a stretch
of river with over a thousand barbel ,and ive been lead to belive
that in five years our club will have some of the best barbel fishing
in the county! (hopefully),the fish that were stocked were said to be
two years old. Anyone know ?
cheers jel.

Hi Jel,

Growth rates vary dramatically from water to water and in ideal conditions, growth can be quite fast. A one year barbel may grow to six inches in length and weigh 0.5lb. By the third year, the fish will have more than doubled in length and weigh as much as 1.5lb. Years six to eight could see a weight of 5 lb, while a barbel weighing 10 lb may be eleven or twelve years old. Between twelve and fifteen years old they could potentially reach 15lb.

The variables that can make all the difference in growth rates are the water quality, temperature and availability of foodstuffs.
If the water is well oxygenated and clear of pollutants even natural ones such as iron, the fish will thrive. On the other hand poor quality water will cause stress in the fish which then has an adverse effect on their growth.

Food availibilty is dependant on the natural foodstocks and competition from other species. Barbel tend to prefer gravelly beds for feeding from rather than silty ones so again if your water has some of these you will find that the fish will move into them.

Hope this helps, Dave
