What Hydrosphère does

Hydrosphère is a privately held French environmental consulting firm founded in 1998 (continuing the activity of E.A.E Consultant established in 1993 by engineer-ecologist Pascal Michel) that specializes in the expertise and development of aquatic environments. The company delivers integrated professional services across four pillars: expertise and diagnostics (hydrobiology, ichthyology, hydrology); ecological engineering and project management (feasibility studies, design, construction supervision, regulatory dossiers); research and innovation (proprietary tools such as the PPIB expert system, IFh/IFS fish indices, and a patented automatic water-level regulation gate); and training and communication for river managers and the public. Its operations span three regional agencies in France (Île de France headquarters in Saint-Ouen-l'Aumône, Occitanie, and Méditerranée), serving public-sector project owners including municipalities, intermunicipal communities, river syndicates, departmental councils, and fishing federations.

The firm's underlying technology combines biological sampling protocols, standardized hydrobiological indices (I2M2, IBD, IBMR, MGCE), electric fishing, environmental DNA (ADNe) work via a research partnership with SPYGEN, and proprietary predictive models developed from long-term field datasets. The PPIB software quantifies impacts of riverbank works on fish vital functions (shelter, nutrition, reproduction, growth), while IFh and IFS indices evaluate spawning ground integrity against the EU Water Framework Directive's "good ecological status" objective. A patented automatic closing-gate system optimizes pike spawning-ground flooding on regulated large water bodies.

Hydrosphère operates a B2B, sales-led professional services model with project-based, quote-driven pricing delivered through direct consultation. Revenue is generated through consulting fees for studies, engineering work, regulatory dossiers, and training modules. The company maintains a deliberately controlled, organic growth posture and does not disclose revenue, funding, or headcount metrics. GTM channels are limited to a website contact form, LinkedIn presence, and downloadable brochures; no intermediary or digital marketing channels are used.

Core offering

Hydrosphère is a French consulting firm specializing in expertise and ecological engineering for aquatic environments. The firm delivers hydrobiological, ichthyological, and hydrological diagnostics, feasibility studies, construction supervision, and regulatory dossiers to public project owners (Maîtres d'ouvrage). It also conducts proprietary R&D producing tools such as the PPIB expert system, new fish indices (IFh/IFS), a patented automatic water level regulation system, and an ADNe sampling protocol, while offering technical training for river managers.

Product overview

Hydrosphère is a specialized consulting firm providing integrated aquatic environment studies and development services. The company offers four core service pillars: (1) Expertise and Diagnostic covering hydrobiology, ichthyology, and hydrology; (2) Ecological Engineering and Project Management including feasibility studies, construction supervision, and regulatory files; (3) Research and Innovation developing proprietary tools like PPIB software and fish indices; and (4) Training and Communication including technical training modules and communication tools. The flagship proprietary product is the PPIB (Potentialités Piscicoles des Berges) expert system software for quantifying fish habitat impacts of riverbank development.
