Ecosure has strengthened its aquatic ecology capability with the addition of a new estuary‑capable electrofishing boat, equipped with a Hans Grassl GmbH system purpose‑built in Germany for precision, safety and performance.

This system is one of only two in Australia, giving Ecosure a rare ability to undertake high‑quality electrofishing across freshwater, brackish and estuarine environments. For clients and for Australia’s waterways, this represents a significant step forward in aquatic monitoring and management.

Why Estuary Capability Matters

Estuaries are among Australia’s most productive and ecologically important ecosystems, supporting fish nurseries, migratory species, fisheries, and sensitive mangrove and saltmarsh communities. They are also technically challenging environments to survey, with fluctuating salinity affecting electrical conductivity.

The Hans Grassl estuary‑capable unit is designed to adapt to these changing conditions, allowing Ecosure to safely and consistently sample across tidal and brackish systems. This delivers more reliable data, broader spatial coverage and stronger ecological and compliance outcomes.

Supporting Best‑Practice Aquatic Management

Electrofishing is a proven, science‑based technique used to temporarily stun fish so they can be identified, measured, assessed and safely released. It plays a critical role in fish community assessments, invasive species detection, native fish salvage, long‑term monitoring and impact assessment programs.

The new vessel allows Ecosure to undertake boat‑based electrofishing in wide rivers, dams, lakes and estuarine reaches that are difficult to sample using shore‑based or backpack methods alone.

Strengthening Invasive Fish Management

This capability directly supports Ecosure’s invasive fish management programs, including tilapia removal across Queensland. Operating seamlessly across freshwater and estuarine systems improves detection and removal efficiency while protecting native fauna.

Expertise Across Catchments and Coasts

Ecosure’s aquatic ecologists work across freshwater, estuarine and marine environments, with a strong understanding of ecological linkages from headwaters to the coast. All works are delivered under certified Quality, Environmental and Safety systems aligned with Ecosure’s Zero Harm principles.

Looking Ahead

With one of only two estuary‑capable electrofishing systems in Australia, Ecosure is uniquely positioned to deliver high‑quality aquatic assessments across the full freshwater‑to‑marine continuum — supporting better science, stronger compliance and healthier waterways.
