Fisheries and aquaculture operations rely on stable, predictable water conditions — but floating debris, invasive aquatic vegetation, and uncontrolled fish movement can disrupt daily operations and threaten fish health. Whether managing a hatchery, running an aquaculture pen system, or maintaining a natural river fishery, operators need tools that help create structure and protect sensitive areas. One of the most effective tools is the floating barrier, a versatile containment system used to control debris, guide fish behavior, and manage plant accumulation.
Elastec has developed a suite of floating barriers designed specifically for freshwater and inland fishery environments, offering long-lasting, field-tested solutions for conservation groups, tribal nations, state agencies, and aquaculture professionals.
1. Managing Debris for Healthier Fisheries
Floating debris is one of the most common challenges in fisheries — especially those located along rivers or reservoirs. Seasonal floods and high-water events can push logs, vegetation mats, and man-made trash into fish passages, hatchery raceways, and aquaculture systems. Not only does this debris disrupt water flow, but it can damage infrastructure and create dangerous conditions for staff.
Elastec Brute Boom is specifically engineered for high-impact debris environments. Its large-diameter floats and reinforced hardware allow it to intercept and hold logs and storm debris before they reach sensitive areas. In upstream fisheries where debris threatens fish ladders or overwintering zones, installing a Brute Boom across key inlets dramatically improves operational reliability.
2. Protecting Intake Structures & Flow Control Systems
Most hatcheries and aquaculture facilities depend on clean, consistent water flow. Intake structures are vulnerable to debris buildup, drifting vegetation, and fish overcrowding, which can reduce water quality and stress fish populations.
Floating barriers help:
- Keep debris away from intake screens
- Maintain flow uniformity
- Prevent equipment clogging
- Extend the maintenance cycle
- Reduce emergency shutdowns during storm events
For long-term protection, Elastec PermaFence is ideal. Designed for permanent deployments, it resists UV exposure, ice, and seasonal temperature changes. It’s a “set-and-forget” solution for fisheries that need year-round protection.
3. Fish Guidance & Exclusion Solutions
Guiding fish into the correct channels — or keeping them out of restricted areas — is critical for fisheries management. Proper guidance reduces stress, improves migration success, and protects fish from hazards like turbines, research zones, feeding lanes, or industrial structures.
Elastec Net Boom delivers an easy-to-deploy solution for:
- Directing fish toward ladders
- Keeping fish out of turbines or gates
- Separating species in multi-stock environments
- Creating temporary migration corridors
- Protecting rearing areas
Fishery teams often use Net Boom during migration periods, seasonal raises in water flow, or temporary maintenance windows.
4. Controlling Aquatic Vegetation
Invasive plants such as milfoil, water hyacinth, and floating grass mats can obstruct fisheries operations, limit water flow, and reduce oxygen levels. When vegetation collects around pens, cages, or hatchery raceways, it can suffocate fish, alter water chemistry, and require constant manual clearing.
Floating barriers give operators a way to redirect or contain vegetation before it enters critical infrastructure. By creating a defined perimeter and preventing plant buildup, fisheries can maintain healthier, more stable water conditions.
5. Supporting Habitat Restoration & Conservation
Restoration projects often require the separation of sensitive habitats from main channels — for example, juvenile rearing zones or protected spawning areas. Floating barriers help conservation teams maintain these zones and prevent disturbance from debris or unwanted species.
Elastec systems are frequently used by:
- State fish & wildlife agencies
- Watershed conservation groups
- Tribal fisheries
- Hydropower mitigation programs
- University research teams
Floating barriers are one of the most practical, affordable, and effective tools available to fisheries and aquaculture operators today. From protecting intake systems to guiding fish movement and keeping debris out of critical areas, the right boom can dramatically improve operational stability and fish health.
Elastec offers a full range of solutions — including Brute Boom, Net Boom, and PermaFence — designed specifically for the demands of freshwater fisheries.
