WHS 3250

Features common to the submersible receiver models in this series include:

• Autonomous, underwater node – complete with hydrophone, receiver, logger in waterproof/submersible (400 m) package
• CDMA code division multiple access coding results in higher probability of detection
• 250 millisecond ID burst – robust against code collision in multi-tag congregations and multi-path/echo environments
• Over 80,000 unique ID codes
• Supports ID and sensor data transmission (temperature, pressure/depth, motion)
• Relative received signal strength indication
• Remote receiver status monitoring via Bluetooth cable
• Small, rugged form factor simplifies deployment andf recovery
• Easy access to primary battery pack and USB for re-battery and high speed data download
• Low cost and light weight – minimizes deployment resources required
• Supports mobile tracking for real time data collection
• Compatible with Lotek UMAP positioning software for continuous 2D or 3D (with depth tags) fish tracks
• Integrated transmit beacon – provides ongoing assurance of system functionality and a means for receiver location and recovery

What does the migration behavior of Tanner Crab in the Bering Sea, Chinook Salmon and White Sturgeon in the Columbia River, Pallid Sturgeon in the Missouri River and Striped Bass from the Hudson River to the Gulf of Mexico have in common?

Over the past two decades, MAP acoustic telemetry systems have been assisting biologists and fisheries managers involved in this research, answering important questions regarding these fish behaviors.

Applications include:

• Fish passage/guidance efficiency studies
• Adult salmon fallback
• Prespawn mortality
• Fish behavior, congregation, responses to anthropogenic disturbance
• Habitat use and species interactions
• Migration behavior and timing
• Continuous 2D and 3D (2D + depth tags) positioning

From monitoring reef fish behaviors in the Indian Ocean and around oil rigs in the Gulf of Mexico, to assessing the impacts of dams on fish migration in the Amazon River, researchers with leading Federal Agencies and Institutions world-wide have selected MAP acoustic systems to assist in elucidating these behaviors.

The MAP WHS 3250 now affords all researchers with a fish research and management mandate, even those working under tight budget constraints, an efficient and affordable acoustic system solution. Call us to discover more about how MAP Acoustic systems can provide a solution for your project.
