Fatty acids in ten species of fish commonly consumed by the Anishinaabe of the upper Great Lakes

Abstract

The Chippewa Ottawa Resource Authority (CORA) in Sault Ste. Marie, Michigan, has been monitoring contaminant concentrations in the fillet portions of fish from the 1836 treaty-ceded waters of lakes Superior, Huron, and Michigan since 1991. The goal is to provide up to date consumption advice for their CORA member tribes. For the first time since the program started, CORA has included fatty acid analysis in 2016 monitoring of fish in Lake Superior. Ten species were targeted by CORA based on 25 years of experience and regular discussions with Anishinaabe fish consumers. This paper reports these results and presents some preliminary discussion of the consequences for consumption advice for the CORA member tribes who inhabit the Great Lakes region. Six of the species were sampled from Lake Huron and Lake Superior and four were sampled from supermarkets. Wild caught fish are an important link to the culture of Great Lakes Native American tribes and important sources of food and omega-3 polyunsaturated fatty acids (PUFA N-3). While some PUFA N-3 data from the Great Lakes is available, this dataset provides an important supplement and is specific to the 1836-treaty ceded waters of CORA. This paper confirms the presence of PUFA N-3s in Great Lakes fish traditionally harvested by the CORA tribes.

Total Mercury and Fatty Acids in Selected Fish Species on the Polish Market: A Risk to Human Health

“…Dellinger et al [ 70 ] studied six fish species, including lake trout, and noted intra- and interspecies variability. In another example, a strong relationship between feeding behavior and fatty acid composition of the muscle lipids of fish from subalpine lakes was observed by Vasconi et al [ 71 ].…”

Evaluating Benefits and Risks of Polyunsaturated Fatty Acids and Methyl Mercury from Fish and Seafood Consumption in Peninsular Malaysia

“…Yet, these substitutions are not perfect. Signifcant diferences in the fatty acids profle within species occurred due to other factors as well, for instance, fsh species, genetics, harvesting seasons, reproductive cycle, and environmental characteristics [31,38,[40][41][42]. Mahafey [43] reported on a general coherent pattern of fatty acid composition for fsh and shellfsh species, but the relationship between ω-3 fatty acids and the fat content of all species is not a simple linear association.…”

“…Tey highlighted all taxonomic families from Great Lakes species and in-land salmonid fllets containing ≥250 mg/227 g fllet (or ≥110 mg/100 g EPA + DHA). In contrast, Dellinger et al [41] listed a few Great Lakes species (walleye, rainbow smelt, lake herring, yellow perch, whitefsh, and lake trout) that contained a high concentration of these fatty acids at a range between 244.2 and 2,395.3 mg/100 g. Gribble et al [39] summarized data on EPA and DHA across fsh populations in their review. Tey discovered that order Clupeiformes (e.g., sardine, Sardinops sagax), followed by order Salmoniformes, has the highest concentrations of ω-3 PUFA.…”
