Open for Spawning: Monitoring the Salinas River

Formed by the confluence of the San Antonio, Nacimiento, and Arroyo Seco rivers, the 172-mile-long Salinas is the largest river on California’s Central Coast, and it supports a small run of threatened steelhead (Oncorhynchus mykiss). The status of this South Central California Coast Distinct Population Segment (SCCC DPS)  is of interest to both researchers and […]

Salinas River Steelhead PIT Tag Antenna Array

FISHBIO designed and fabricated a PIT tag antenna array for the Nature Conservancy to answer questions about steelhead (Oncorhynchus mykiss) movement and behavior in the Salinas River basin on the central California coast. The Salinas River is a dynamic and sometimes challenging environment to study, due to its shifting, sandy riverbed and the “flashy” flows […]

Steelhead and the Continually Changing Carmel River

Like the city of the same name, the Carmel River is small and picturesque, nestled in the hills of the Carmel Valley. The average passerby may not realize the importance of this little stream, both for fish that call it home as well as hundreds of thousands of people living on the Monterey Peninsula. The […]

Fish in Fickle Rivers

A desert may seem an unlikely home for a freshwater fish, but many species find a way to scrape by. In order to survive, desert fish have to be ready to take advantage of habitats when they are available. Brief periods of rainfall can send  flow down tributaries that are normally dry, opening up new […]

Reconnected River

Steelhead can live in the Salinas River watershed, but their ability to access this habitat depends largely on the rain forecast and river water levels. While the main-stem Salinas River is not ideal habitat for adult steelhead spawning, small reaches of suitable habitat exist in Santa Margarita, Nacimiento, and possibly San Antonio rivers in some […]

Riverwatchers unite!

The Riverwatcher infrared fish scanner, developed by Vaki Aquaculture Systems Ltd. in Kopavogur, Iceland, is a truly international tool for monitoring fish migration. The Riverwatcher collects data with infrared scanning technology and high-resolution cameras to count and identify migrating fish species. These devices are now used at more than 300 sites all over the world, […]

Salinas Basin Monitoring

The Salinas River Diversion Facility increases the water available for irrigation in California’s agriculturally rich Salinas River Valley. To identify the effects of the diversion facility on threatened South-Central California Coast steelhead and their critical habitat, FISHBIO conducts a comprehensive juvenile steelhead outmigration monitoring program for the Monterey County Water Resources Agency, which operates the […]

The FISHBIO Countdown of 2020

Like the many who are eager to tick off the minutes until the end of 2020, we have put together our own FISHBIO countdown to wrap up a year like no other: 4,300 fish relocated from Phoenix Lake 3,284 fish PIT tagged on the San Joaquin, Stanislaus, and Calaveras Rivers 1,451 estimated rainbow trout in […]

FISHBIO Highlights of 2020

The past year has been challenging for the entire world, and for us at FISHBIO it has been no exception. Yet despite the difficulties of the coronavirus pandemic, shutdowns, and wildfires, we had the fortunate ability to continue much of our work surveying fish and rivers. Our family-style business came in handy when we could […]
