Gathering local ecological knowledge to augment scientific and management understanding of a living coastal resource: The case of Oregon’s nearshore groundfish trawl fishery
جمع آوری دانش زیست محیطی محلی برای تقویت درک علمی و مدیریت از یک منبع ساحلی زنده: مورد ماهیگیری ماهی قرمز مایل به قرمز اورگان-2021 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. keywords: دانش زیست محیطی محلی | زمین های دریایی ساحل غربی ایالات متحده | اطلاعات وابسته به ماهیگیری | ماهیگیری ساحلی | Local ecological knowledge | US West Coast groundfishes | Fisheries-dependent data | Coastal fisheries |

Going on and off the map: Lessons from Swedish fisher knowledge about spawning areas in the Baltic Sea
رفتن به داخل و خارج از نقشه: درسی از دانش فیشر سوئد در مورد مناطق تخم ریزی در دریای بالتیک-2021 Scholars frequently promote fishers’ rich understanding of marine environments as a legitimate and unique form
of knowledge that must be accounted for in fisheries management. It is, however, challenging to combine fisher
knowledge (FK) with the conventional scientific knowledge that fisheries management relies upon. In this paper
we investigate the (in)commensurability between FK and scientific objectives and procedures. Towards this aim
we performed interviews with a group of fishers who participated in an earlier Swedish study in which FK was
used to map locations of fish spawning areas along the Swedish Baltic coast. By interviewing these fishers again
we were able to identify and assess aspects of FK that were left implicit in the earlier study. Based on our results
we discuss the value of these aspects of FK for understanding marine environments. keywords: دانش زیست محیطی محلی | روش های کیفی | ماهیگیری در مقیاس کوچک | دانش زیست محیطی سنتی | Local ecological knowledge | Qualitative methods | Small-scale fisheries | Traditional ecological knowledge |
