The Mesopotamian Goby: A Secret of the Seine River.

Seine River Goby: Ecological Assessment & Decline

The Mesopotamian Goby (*Mesogobius batrachocephalus*) is a keystone species within the Seine Estuary ecosystem, playing a critical role in the food web. Its sensitivity to environmental changes makes it a valuable bioindicator. Recent data reveals a concerning population decline, potentially due to deteriorating water quality. This study offers a preliminary assessment of the challenges facing this species.

Ecological Challenges

This study focuses on the ecological challenges facing the Mesopotamian Goby in the Seine Estuary. The high sensitivity of this species to environmental fluctuations, including pollution, temperature, and flow regimes, highlights its importance as a bioindicator of ecosystem health.

Reproduction and Habitat

Reproduction occurs in the Seine Estuary during spring, with larval development dependent on sufficient food resources. Bathymetric analysis shows an uneven distribution, suggesting a preference for habitats rich in aquatic vegetation.

Pollution Impact

Elevated nitrate and phosphate levels detected in water samples from certain areas may negatively impact Goby growth and survival.

Conservation Needs

Sustaining Mesopotamian Goby populations requires mitigating pollution and improving water quality. The effectiveness of current conservation strategies needs further evaluation. This study calls for expert recommendations to address the identified challenges.
