Gathering and Synthesizing Critical Data

Cramer Fish Sciences is a recognized expert in the design and implementation of fish habitat and population monitoring projects. Our monitoring is focused on improving our knowledge about aquatic ecosystems. We are adept in applying innovative technologies and optimal sampling designs to efficiently assess status and trends. We also have biostatisticians and biologists that are experienced with sophisticated statistical analysis to describe meaningful patterns, relationships, and trends. We are equipped with a fleet of boats, a storehouse of sampling gear, and a full shop for fabrication and maintenance of field gear. Our services include:

Fish Population Monitoring Migration Migrant traps Resistance board weirs Radio and acoustic tracking Survival Tagging (PIT, CWT, telemetry) Distribution and Population Trends Electrofishing (boat and backpack) Underwater video/infrared Snorkeling/diving surveys Seine and gill netting Growth Scale and otolith analysis Diet analysis
