Eckström's topknot

Eckström's topknot (Phrynorhombus regius) is a species of marine fish in the family Scophthalmidae. Contrary to some classifications that might mistakenly label it as a plant pest, this organism is an aquatic vertebrate inhabiting the northeastern Atlantic and the Mediterranean Sea.

Systematically, it belongs to the order Pleuronectiformes. Its entire life cycle, from larval stages to maturity, occurs within marine environments. It feeds on small invertebrates and benthic organisms, having no trophic relationship with terrestrial vegetation or crops.

As this species is not an insect or a mite, it does not damage crops. It lacks the specialized mouthparts required to consume plant foliage, stems, or roots. Therefore, it does not pose any economic or biological threat to agricultural productivity in any region.

There are no recorded cases of damage caused by this species to agricultural fields, greenhouses, or stored agricultural products. The classification of this fish as a pest is scientifically inaccurate and likely a data entry error in certain biodiversity databases.

No protection measures are necessary for this species in an agronomic context. Farmers should concentrate their pest management efforts on known agricultural pests such as aphids, beetles, or caterpillars that significantly impact plant health and yield quality.
