2021 Alaska Fisheries Science Center Groundfish Seminar Series
2021 Groundfish Seminars held virtually using Webex - Tuesdays @ 10am Pacific.
The Groundfish Seminar Series (2016 – present) at the Alaska Fisheries Science Center (AFSC) starts in early October and ends in mid-December. We host 9 or 10 weekly talks on Tuesdays at 10AM Pacific Time, with speakers from both inside and outside of the AFSC. The purpose is to provide a friendly venue for connecting researchers in the widely dispersed groundfish community so that we can learn about advancements in other geographic locations, or on other species, that might be applicable to you and your work. We encourage speakers to talk in general terms about works-in-progress or newly published findings that might be of interest to a broad community.
The seminar series is hosted by the Groundfish Assessment Program at the AFSC and, as a well-attended seminar series at the AFSC, we attract an audience from other parts of the AFSC, the other five NOAA Fisheries science centers, NOAA Fisheries regional offices, NOAA Fisheries headquarters, other parts of NOAA, non-NOAA parts of the federal government, state agencies, universities, the fishing industry, non-governmental organizations, and independent research groups.

Building a cooperative rockfish survey in the Gulf of Alaska.
The AFSC and our partners in the Alaska fishing industry just completed the first summer of data collection in a cooperative rockfish survey. Our project, the Science Industry Rockfish Research Collaboration in Alaska (SIRRCA), aims to improve rockfish assessment models through partially standardizing industry trawls in "untrawlable" areas. Come learn more about what SIRRCA has accomplished thus far and the bigger promise of government industry cooperative research.

Filling science gaps in response to an unprecedented increase in redfish (Sebastes mentella and S. fasciatus) biomass in the Gulf of St. Lawrence.
The Gulf of St. Lawrence, Canada, redfish supported substantial landings in the mid-1950s until a sudden drop in landings and the absence of strong recruitment led to a moratorium in 1995. According to DFO surveys, the biomass is now the highest value of the time series starting in 1984. How can we conduct sustainable harvests without repeating the mistakes from the past?

Grand challenge for habitat science: Synthesis of fishing effects, stage-structured dynamics and movement (with a few toy demos).
The AFSC conducts “habitat assessments” by tracking depletion and recovery of benthic infauna/epifaunain occupied habitat. I propose a “Grand Habitat Challenge” (GHC) to improve these assessments by combining habitat and stock assessment tools. Two real-world examples will address components of the GHC including how to (1) estimate fine-scale movement from tags and surveys, and (2) estimate diet using a simple generalized linear model (GLM).

Stress physiology in the smalltooth sawfish: Effects of ontogeny, capture method, and habitat loss.
What does a gigantic fish with a hedge trimmer for a snout have to be stressed about? Come learn about the physiology of smalltooth sawfish, Pristis pectinata, one of the world's most endangered species of marine fishes. Specifically, we investigated how stress in this species changes over ontogeny, with varying capture methods, and how habitat loss may be affecting juveniles.
