Trout and Char of the World
Published by the American Fisheries Society
This book is the first comprehensive look at the taxonomy, life history, and conservation status of the world’s trout and char. These are fascinating and beautiful fish that rate high for the angler as well as for tourist and recreational economies. Trout and char also play key roles in the ecology of many lake and river systems around the world.

A call for global action
A 2019 international symposium titled “Advances in the Population Ecology of Stream Salmonids V” held in Granada, Spain included a special session entitled, “The Status and Conservation of Trout and Char Worldwide.” Attendees rallied to seek solutions and to introduce a new impetus to raise the global awareness of these iconic fishes and protect, conserve and restore trout and their habitats. The session presentations and ensuing forum repeatedly focused on a set of three themes: (a) a lack of coordination among or communication about conservation efforts internationally; (b) decentralised or unavailable data concerning current species status assessment and habitat threats and serious gaps in our knowledge about the evolution and ecology of many trout species and lineages; and (c) an absence of globally applied place-based conservation actions. We propose and describe here three critical objectives to address these limitations and uncertainties.
Lahontan Cutthroat Trout
Twelve-thousand years ago, there was a lake - Lake Lahontan - that covered more than 8,500 square miles of the Great Basin. Most of the rivers and lakes there today were at some point tributaries to this giant lake, or wholly covered by it. What does that mean for a species that’s been in the Great Basin for more than 10 million years in one form or another? It tells us that these fish were once widespread across the landscape with no barriers to movement, so they were likely well distributed without much genetic difference.
