October 26, 2026 — Longfin squid is an economically important species that is challenging to study. Mostly caught from Rhode Island to New Jersey, it supports a commercial fishery worth approximately $32.5 million in 2024. It is often found on restaurant menus as calamari.
Longfin squid live less than a year, grow rapidly, and the number of young entering the population is highly variable. Their populations are influenced by dynamic ocean conditions, leading to shifts in abundance and distribution that are challenging to understand or predict. Longfin squid migrate with the seasons, generally moving south and offshore in the late fall and returning north and inshore during the spring. Scientific surveys capture seasonal snapshots of the population but they cannot provide specifics about the squid caught in the fishery.
Successful Research Track Peer Review
In August 2026, an independent panel of scientists completed the peer review for the Longfin Inshore Squid Research Track Assessment. The panel approved two new assessment models—both of which met all required Terms of Reference and were deemed suitable for management advice. These models mark a significant technical advancement over past index-based approaches. They are better able to capture the rapid growth, seasonal changes in abundance, and unique biology of this short-lived species.
This major accomplishment for a historically data-poor species was possible because of strong collaboration between scientists and commercial fishing industry partners. Having a better foundational understanding of longfin squid life history, as well as two distinct and credible models, gives managers greater flexibility and confidence in using the best available science. The review marks an important milestone in the multi-year effort to improve our understanding of longfin squid and develop better tools to assess the stock. The findings will be implemented during the upcoming Longfin Squid Management Track Assessment this fall.
We combined analytical expertise of scientists with on-the-water knowledge of fishermen who encounter this species throughout the year, making great strides together toward better understanding this economically important and enigmatic species.
“The foundation of trust and collaboration between the science and fishing communities was critical to the scientific progress made during the longfin squid assessment. From sharing ecological observations to collecting data to providing input on model assumptions and outputs, industry partners played a critical role in all phases of the assessment,” shared Dr. Anna Mercer, chief of the center’s Northeast Cooperative Research branch.
The goals of the collaboration are:
- Better science for sustainable management
- Better information to support decisions about how much seafood can make its way from the ocean to our tables
