The species in EA surveys

About flounder

RiverFish's flounder profile shows observed river distribution, recent surveys and individual measured lengths.

The largest length in RiverFish's EA sample is 47 cm; the largest recorded weight is 0.450 kg. These maxima may describe different fish.

EA survey maxima are population-monitoring measurements, not authenticated angling records. They are not necessarily representative of the largest fish in British waters. No weight is estimated from a survey length.

Published name Pleuronectes flesus mapped explicitly to Platichthys flesus. Angling categories remain separate even when EA groups them under one species.

RiverFish preserves original classifications, joint holders and location strings. Weekly checks compare the HTML with the official PDFs. Unresolved values are flagged. A named river stretch receives a river relationship only when its geographical identity is established; stillwaters and ambiguous names do not receive river awards.
