Watching native fishes vanish

Andrew Rypel & Peter Moyle, CALIFORNIA WATER BLOG

It’s an odd, disturbing feeling – watching populations of native fish species collapse and then disappear. Sometimes it happens quickly, other times it’s a series of slowstep change events. The end result is the same though – smaller populations, extinctions, less biodiversity. We put up a little fight, and occasionally have moderate success. But by and large, the overall trend is down, the pace of change quickening, and it is relentless. We’ve watched it over our careers, and maybe some of you have too. Either as biologists or water professionals, or perhaps as long-time readers of this blog. This summer has been no different. It has been an avalanche of stories, all with variations on this theme. Here, we provide a synopsis of some recent events, along with wider thoughts on what watching this happen means.

When we lose species, it speaks volumes about our inability to prevent ecosystem decline, and to constantly borrow from nature without repayment (Rypel 2023). The pattern is especially sobering with charismatic species such as Chinook salmon, which receive large amounts of conservation funding and attention. This is a clear and unambiguous signal that cannot be ignored. But what should we do about it? A good start might be the development and implementation of a comprehensive fish management plan for California. We provided some scaffolding for what such a plan might look like in a previous blog. The 30×30 conservation goal of the Resources Agency can boldly protect many declining fishes if fully implemented. This initiative seeks to directly protect entire watersheds, including where many declining fish occur.
