Tomarata lakes pest fish netting


TOMARATA LAKES PEST FISH SURVEY

On the 29th of october room3 went to Tomarata lakes to do a survey on the pest fish netting.



The Tomarata lake managment committee had organised pest fish netting and invited room 3 to come along and do a survey on how many rudd, trout, koi and tench they caught and then weigh and measure them.



Craig Stevens had a talk to us about the lake, the fish and their history.



Tomarata lake is a dune lake and is eutrophic, that means it is murky with higher amounts of nutrients and algae.



The Rudd is just one type of fish that they are netting, they eat the native weed which affects the water quality and also other fish like trout and tench.



At the end of our survey we were left with these results.
85 rudd, 17 trout and 1 tench.
