چکیده انگلیسی:
Globally, coastal nearshore regions are an intersecting point for human and biological productivity, often serving
as hotspots for subsistence, commercial, and recreational fishing activities. Despite this, many nearshore areas
remain poorly understood, monitored or managed. This case study examined the nearshore sector of Oregon’s
groundfish trawl fishery, which exists in shallow estuarine and continental shelf habitats common along the West
Coast of North America; areas that are important for early life history stages of many commercial and recrea-
tional fisheries. The West Coast groundfish fishery includes over 90 different species, 40 of which occur within
Oregon’s nearshore (here defined as the portion of the shelf extending seaward to a water depth of 200 m). The
very shallow portions of the Oregon Coast (the area of the shelf inshore of 55 m) have been subject to limited
scientific survey monitoring, and much of the details of the ecology, health, and processes in these habitats
remain poorly understood. The utilization of the nearshore region by the commercial groundfish trawl fleet is
also minimally documented despite the fact that experiential knowledge (local ecological knowledge [LEK];
trawl logbooks, fish tickets, interviews) exists. This research explored the capacity of capturing LEK sources to
inform and enhance understanding of the drivers of effort and the vitality of nearshore fishery resources. Our
approach used statistical analysis and mapping of nearshore trawl effort from 1981 to 2017 and gathered semi-
structured interviews of intergenerational fishermen to bolster data-poor areas. Insights provided by sampling
strategies and historical to current knowledge of access to groundfish assemblages provide informed baselines for
future management. Spatial mapping results revealed a decline in trawl effort on the Oregon continental shelf
thought time. Logbook and interview data assessment illuminated market and ecological drivers of fishing
behavior as well as a unique sector of the groundfish fleet in Oregon: the beach fleet, with unique market and
socio-economic challenges. Findings indicate a mixed-methods approach can provide a more thorough assess-
ment of long-term interest in Oregon’s nearshore groundfish fishery. Ensuring better understanding of coastal
interfacing regions such as Oregon’s nearshore insights potential for better conservation and utilization of marine
resources and improved monitoring in resource limited management contexts.
