Our new paper is out in Environmental Science & Technology.

Lake deoxygenation favors elevated tissue mercury and decreased selenium, altering the nutrient-toxin profile of a food fish.

The better ability of wild fishes to meet multiple nutrients simultaneously underscores the importance of drawing upon a diverse portfolio of animal- and plant-based foods as societies seek to offset changes in fisheries while achieving healthy and sustainable diets.

[Sebastian Heilpern @heil_seb]

Wild fishes are incredibly diverse in their nutrient content. Hence, their replacement with farmed animals would require large increases in portion sizes to achieve comparable nutrient intakes.

This challenge is magnified in fishery-dependent nations with high biodiversity.

[Sebastian Heilpern @heil_seb]

Sustaining the dietary contributions fish make to people given declining biodiversity could require more biomass and ultimately exacerbate fishing pressure in already-stressed ecosystems. 3/3

Using household consumption data from the Amazon and Mekong (two of Earth's largest rivers, mind you!) we find that diverse fish portfolios can sustain more nourishing diets with less biomass, although this #biodiverisityeffect depends on how reliant people are on fisheries.
